Plaintiff S157/2002 v Commonwealth of Australia

[2003] HCA 2

S157/2002

ORDER

The questions reserved for consideration by the Full Court are answered as follows:

Question 1

Is section 486A of the Migration Act 1958 (Cth) invalid in respect of an application by the plaintiff to the High Court of Australia for relief under section 75(v) of the Constitution?

Answer

Upon its proper construction, s 486A does not apply to the proceedings the plaintiff would initiate.  No question of the validity of s 486A arises in that regard.

Question 2

Is section 474 of the Migration Act 1958 (Cth) invalid in respect of an application by the plaintiff to the High Court of Australia for relief under section 75(v) of the Constitution?

Answer

Section 474 would be invalid if, on its proper construction, it attempted to oust the jurisdiction conferred on the High Court by s 75(v) of the Constitution. However, on its proper construction, it does not attempt to do so. Section 474 is valid but does not apply to the proceedings the plaintiff would initiate.

Question 3

By whom should the costs of the proceeding in this Honourable Court be borne?

Answer

The Commonwealth should pay 75 per cent of the costs of the plaintiff of the proceeding.

1. GLEESON CJ. The plaintiff wishes to institute proceedings against the Minister for Immigration and Multicultural and Indigenous Affairs ("the Minister"), and the Refugee Review Tribunal ("the Tribunal"), invoking the jurisdiction of this Court under s 75(v) of the Constitution to issue writs of prohibition and mandamus against officers of the Commonwealth, and the power, in an appropriate case, to grant ancillary relief in the form of certiorari[1]. The proceedings in contemplation concern a decision of the Tribunal confirming a refusal to grant the plaintiff a protection visa. The proposed challenge to the decision is based upon the ground of a denial of natural justice "in that [the Tribunal] took into account material directly relevant and adverse to [the plaintiff's claim of refugee status] without giving him notice of the material or any opportunity to address it". The merits of that contention are not presently in issue. Sections 474 and 486A of the Migration Act 1958 (Cth) ("the Act") present potential obstacles to the proceedings. However, the plaintiff contends that those provisions are invalid. He commenced an action in this Court, against the Commonwealth, seeking declarations of their invalidity. Gummow J stated a case for the consideration of a Full Court, asking, as to each section, in its application to the plaintiff's proposed application under s 75(v), whether it is invalid.

   [1]Re Refugee Review Tribunal; Ex parte Aala (2000) 204 CLR 82 at 90-91 [14].

2. The questions, and the terms of the legislative provisions, are set out in the judgment of Gaudron, McHugh, Gummow, Kirby and Hayne JJ ("the joint judgment"). For the reasons that follow, I agree with the answers proposed in the joint judgment. It is convenient to begin with a consideration of s 474.

   Section 474

3. The first step in the plaintiff's argument, in support of the contention that s 474 is invalid, is an assertion that the section means what it says. It is argued that, in their ordinary and natural meaning, the words of s 474 purport to prevent any applicant from seeking, and any court, including this Court, from granting, any relief with respect to any application for review of a decision of an administrative character (save for some minor exceptions) under the Act. Therefore, the section purports to oust the jurisdiction conferred upon this Court by s 75(v) of the Constitution. The Parliament has no power to do that.

4. The Commonwealth accepts that, if read literally, s 474 would purport to oust the jurisdiction of this Court, and at least to that extent would be invalid. However, the Commonwealth contends that s 474 does not have that meaning. It has a more restricted meaning than that which, at first sight, it appears to convey. It was enacted against a background of established judicial interpretation of similar provisions, and Parliament acted in the light of that interpretation. Furthermore, s 15A of the Acts Interpretation Act 1901 (Cth) requires that an Act is to be "read and construed subject to the Constitution, and so as not to exceed the legislative power of the Commonwealth."

5. Section 75(v) of the Constitution confers upon this Court, as part of its original jurisdiction, jurisdiction in all matters in which a writ of mandamus, or prohibition, or an injunction, is sought against an officer of the Commonwealth. It secures a basic element of the rule of law. The jurisdiction of the Court to require officers of the Commonwealth to act within the law cannot be taken away by Parliament. Within the limits of its legislative capacity, which are themselves set by the Constitution, Parliament may enact the law to which officers of the Commonwealth must conform. If the law imposes a duty, mandamus may issue to compel performance of that duty. If the law confers power or jurisdiction, prohibition may issue to prevent excess of power or jurisdiction. An injunction may issue to restrain unlawful behaviour. Parliament may create, and define, the duty, or the power, or the jurisdiction, and determine the content of the law to be obeyed. But it cannot deprive this Court of its constitutional jurisdiction to enforce the law so enacted. In the Convention debates at the time of the framing of the Constitution, Mr Barton explained the purpose of the provision[2]:

   "This will give the High Court original jurisdiction … in these cases, so that when a person wishes to obtain the performance of a clear statutory duty, or to restrain an officer of the Commonwealth from going beyond his duty, or to restrain him in the performance of some statutory duty from doing some wrong, he can obtain a writ of mandamus, a writ of prohibition, or a writ of injunction.

   …

   This provision is applicable to those three special classes of cases in which public officers can be dealt with, and in which it is necessary that they should be dealt with, so that the High Court may exercise its function of protecting the subject against any violation of the Constitution, or of any law made under the Constitution."

   [2]Official Record of the Debates of the Australasian Federal Convention, (Melbourne), 4 March 1898, vol 2 at 1884-1885.

6. The Parliament cannot abrogate or curtail the Court's constitutional function of protecting the subject against any violation of the Constitution, or of any law made under the Constitution. However, in relation to the second aspect of that function, the powers given to Parliament by the Constitution to make laws with respect to certain topics, and subject to certain limitations, enable Parliament to determine the content of the law to be enforced by the Court.

7. Privative clauses which deprive, or purport to deprive, courts of jurisdiction to review the acts of public officials or tribunals in order to enforce compliance with the law, or which limit, or purport to limit, such jurisdiction, may apply in either State or federal jurisdiction. Many of the considerations relevant to their interpretation and application are common to both[3].

   [3]See, eg, Darling Casino Ltd v NSW Casino Control Authority (1997) 191 CLR 602; Vanmeld Pty Ltd v Fairfield City Council (1999) 46 NSWLR 78.

8. Speaking of a nation with a unitary constitution, Denning LJ said[4]:

   "If tribunals were to be at liberty to exceed their jurisdiction without any check by the courts, the rule of law would be at an end."

   [4]R v Medical Appeal Tribunal; Ex parte Gilmore [1957] 1 QB 574 at 586.

9. In a federal nation, whose basic law is a Constitution that embodies a separation of legislative, executive, and judicial powers, there is a further issue that may be raised by a privative clause. It is beyond the capacity of the Parliament to confer upon an administrative tribunal the power to make an authoritative and conclusive decision as to the limits of its own jurisdiction, because that would involve an exercise of judicial power.[5]

   [5]R v Coldham; Ex parte Australian Workers' Union (1983) 153 CLR 415 at 419.

10. Legislation which confers power or jurisdiction on officials or tribunals, or imposes public duties, or enacts laws which govern official conduct, and which, in addition, deprives, or purports to deprive, courts of jurisdiction to control excess of power or jurisdiction, or to compel performance of duties, or to restrain breaches of the law, involves a potential inconsistency.  A provision that defines and limits the jurisdiction of a tribunal may be difficult to reconcile with a provision that states that there is no legal sanction for excess of jurisdiction.  In 1909, in Baxter v New South Wales Clickers' Association[6], Griffith CJ said:

    "A grant of limited jurisdiction coupled with a declaration that the jurisdiction shall not be challenged seems to me a contradiction in terms."

    [6](1909) 10 CLR 114 at 131.

11. This Court's approach to the interpretation of provisions such as s 474 has been developed over a long period. In Deputy Commissioner of Taxation v Richard Walter Pty Ltd[7], Mason CJ said that "they are effective to protect an award or order from challenge on the ground of a mere defect or irregularity which does not deprive the tribunal of the power to make the award or order".  Some years earlier, in Church of Scientology v Woodward[8], he had said of privative clauses that, "notwithstanding the wide and strong language in which these clauses have been expressed, the courts have traditionally refused to recognize that they protect manifest jurisdictional errors or ultra vires acts".  In both cases, reference was made to R v Hickman; Ex parte Fox and Clinton[9].

    [8](1982) 154 CLR 25 at 55-56.

    [9](1945) 70 CLR 598 at 614-617.

12. The case of Hickman was decided in 1945, but even then there was a history of English and Australian decisions on the meaning and effect of privative clauses.  In 1874, the Privy Council, in Colonial Bank of Australasia v Willan[10], was dealing with a Victorian mining statute, which contained a provision that no proceeding under the statute should be removed or removable into the Supreme Court, subject to certain exceptions.  Their Lordships said[11]:

    "It is, however, scarcely necessary to observe that the effect of this is not absolutely to deprive the Supreme Court of its power to issue a writ of certiorari to bring up the proceedings of the inferior Court, but to control and limit its action on such writ.  There are numerous cases in the books which establish that, notwithstanding the privative clause in a statute, the Court of Queen's Bench will grant a certiorari; but some of those authorities establish, and none are inconsistent with, the proposition that in any such case that Court will not quash the order removed, except upon the ground either of a manifest defect of jurisdiction in the tribunal that made it, or of manifest fraud in the party procuring it."

    [10](1874) LR 5 PC 417.

    [11](1874) LR 5 PC 417 at 442.

13. The concept of "manifest" defect in jurisdiction, or "manifest" fraud, has entered into the taxonomy of error in this field of discourse.  The idea that there are degrees of error, or that obviousness should make a difference between one kind of fraud and another, is not always easy to grasp.  But it plays a significant part in other forms of judicial review.  For example, the principles according to which a court of appeal may interfere with a primary judge's findings of fact, or exercise of discretion, are expressed in terms such as "palpably misused [an] advantage", "glaringly improbable", "inconsistent with facts incontrovertibly established", and "plainly unjust"[12].  Unless adjectives such as "palpable", "incontrovertible", "plain", or "manifest" are used only for rhetorical effect, then in the context of review of decision-making, whether judicial or administrative, they convey an idea that there are degrees of strictness of scrutiny to which decisions may be subjected.  Such an idea is influential in ordinary appellate judicial review, and it is hardly surprising to see it engaged in the related area of judicial review of administrative action.

    [12]See, eg,  House v The King (1936) 55 CLR 499 at 505; Devries v Australian National Railways Commission (1993) 177 CLR 472 at 479.

14. The reasons for judgment of Dixon J in Hickman have been taken up in the approach of Australian courts to privative clauses, both in State and federal jurisdiction.  The decision of the Court was unanimous; and it is important to an understanding of what Dixon J said to note what he and the other members of the Court decided.  Like many of the cases on privative clauses in federal jurisdiction, the proceedings concerned an exercise, or purported exercise, of award-making power by an industrial tribunal.  A Local Reference Board was given, by the National Security (Coal Mining Industry Employment) Regulations 1941 (Cth) ("the Regulations"), power, by arbitral award, to settle disputes between employers and employees in the coal mining industry.  Regulation 17 provided that a decision of a Board should "not be challenged, appealed against, quashed or called into question, or be subject to prohibition, mandamus or injunction, in any court on any account whatever".  A Board made an award purporting to cover truck drivers employed by a transportation company which carried coal, as well as other commodities.  Their employers sought a writ of prohibition in this Court, on the ground that they were not engaged in the coal mining industry.  The employees argued that transportation of coal was part of the coal mining industry.  That argument was rejected.  Prohibition was granted, on the basis that the Board was acting beyond its powers.

15. Dixon J considered, and rejected, an argument that reg 17 excluded relief. He said:[13]

    "The presence of this provision in the Regulations makes it necessary to say whether and to what extent it is ineffectual to protect the decision of the Board from invalidation. In the first place, it is clear that such a provision cannot, under the Constitution, affect the jurisdiction of this Court to grant a writ of prohibition against officers of the Commonwealth when the legal situation requires that remedy. But a writ of prohibition is a remedy that lies only to restrain persons acting judicially from exceeding their power or authority. It is therefore necessary to ascertain before issuing a writ whether the persons or body against which it is sought are acting in excess of their powers; and that means whether their determination, when made, would be void. The Board derives its power from Regulations of which reg 17 forms a part, and that regulation must be taken into account in ascertaining what are the true limits of the authority of the Board, and whether its decision is void."

    [13](1945) 70 CLR 598 at 614.

16. Thus, this Court's jurisdiction to grant prohibition in the event that the Board exceeded its lawful authority could not be taken away by statute. However, the question was whether the Board had exceeded its authority, and that was to be decided by reference to the whole of the Regulations, of which reg 17 formed a part. Dixon J went on to state the primary principle for which his judgment stands[14]:

    "In considering the interpretation of a legislative instrument containing provisions which would contradict one another if to each were attached the full meaning and implications which considered alone it would have, an attempt should be made to reconcile them."

    [14](1945) 70 CLR 598 at 616.

17. The essential problem is the inconsistency between a provision in a statute, or an instrument, conferring a limited power or authority, and a provision which appears to mean that excess of power or authority may not be prohibited.  When the power or authority is conferred by a federal statute, and it is this Court's constitutional jurisdiction to prohibit acts of officers of the Commonwealth in excess of power or authority that the statute purports to take away, a possible solution is that urged by the plaintiff in the present case:  accept the privative clause at face value, and declare it invalid.  However, the reasons of Dixon J show that, although Hickman was decided in the context of federal jurisdiction, he also had unitary constitutions in mind.  And his preferred solution, both in State and federal jurisdiction, was attempted reconciliation.  His view as to how that could be achieved in the case before him was as follows[15]:

    "It is, of course, quite impossible for the Parliament to give power to any judicial or other authority which goes beyond the subject matter of the legislative power conferred by the Constitution … It is equally impossible for the legislature to impose limits upon the quasi-judicial authority of a body which it sets up with the intention that any excess of that authority means invalidity, and yet, at the same time, to deprive this Court of authority to restrain the invalid action of the court or body by prohibition. But where the legislature confers authority subject to limitations, and at the same time enacts such a clause as is contained in reg 17, it becomes a question of interpretation of the whole legislative instrument whether transgression of the limits, so long as done bona fide and bearing on its face every appearance of an attempt to pursue the power, necessarily spells invalidity.  In my opinion, the application of these principles to the Regulations means that any decision given by a Local Reference Board which upon its face appears to be within power and is in fact a bona fide attempt to act in the course of its authority, shall not be regarded as invalid."  (emphasis added)

    [15](1945) 70 CLR 598 at 616.

1. The echoes of what was said by the Privy Council in Willan are discernible.  The concepts of "manifest defect of jurisdiction" and "manifest fraud" are the obverse of what "appears to be within power" and "a bona fide attempt to act in the course of … authority," although it may be noted that, in Willan, the fraud referred to was that of the party procuring the decision.   The last sentence in the passage quoted is the application of the principles stated to the particular instrument in question in Hickman.  By contrast with the complex legislative scheme presently in question, it was a relatively simple instrument.  The Board had power to settle industrial disputes in a certain industry.  In that regard, it had to follow certain procedures.  In Hickman, it was claimed that a purported decision was beyond power because the dispute in question was between parties who were not in the relevant industry.  It might have been thought that the view that they were in the relevant industry was at least fairly open.  There was certainly a bona fide attempt by the Board to pursue its powers.  Even so, the "decision" (Dixon J said he preferred to call it something else[16]), in the Court's opinion, did not on its face appear to be within power. Therefore, it was not protected by reg 17 from judicial interference.

   [16](1945) 70 CLR 598 at 619.

2. Giving effect to the whole of a statute which confers powers or jurisdiction, or imposes duties, or regulates conduct, and which also contains a privative provision, involves a process of statutory construction described as reconciliation.  The outcome of that process may be that an impugned act is to be treated as if it were valid.  Brennan J said in Deputy Commissioner of Taxation v Richard Walter Pty Ltd[17], in a passage quoted by Gaudron and Gummow JJ in Darling Casino Ltd v NSW Casino Control Authority[18]:

   "In so far as the privative clause withdraws jurisdiction to challenge a purported exercise of power by the repository, the validity of acts done by the repository is expanded."

   On the other hand it may be that, as in Hickman, the impugned act is not to be treated as if it were valid. In the case of a purported exercise of decision-making authority, limitation on authority is given effect, notwithstanding the privative provision. That may involve a conclusion that there was not a "decision" within the meaning of the privative clause. In a case such as the present, it may involve a conclusion that a purported decision is not a "decision ... under this Act" so as to attract the protection given by s 474.

   [17](1995) 183 CLR 168 at 194.

   [18](1997) 191 CLR 602 at 630.

3. Limitations or conditions on the exercise of power or authority that are given effect, notwithstanding a privative provision, were described by Dixon J in R v Murray; Ex parte Proctor[19] as "indispensable".  In that case, he described the process of statutory construction contemplated in Hickman as involving two steps[20]. The first step is to note that the protection afforded by a provision such as reg 17 will be inapplicable unless there has been "an honest attempt to deal with a subject matter confided to the tribunal and to act in pursuance of the powers of the tribunal in relation to something that might reasonably be regarded as falling within its province". The second step is to consider "whether particular limitations on power and specific requirements as to the manner in which the tribunal shall be constituted or shall exercise its power are so expressed that they must be taken to mean that observance of the limitations and compliance with the requirements are essential to valid action". In explanation of the second step, Dixon J referred, by way of analogy, to the distinction between statutory provisions that are directory and those that are mandatory[21].  That distinction is now in disfavour[22].  Even so, the process of ascribing legislative purpose, which underlay the distinction, is one with which courts are familiar.  The question is "whether it was a purpose of the legislation that an act done in breach of the provision should be invalid."[23]

   [22]Project Blue Sky Inc v Australian Broadcasting Authority (1998) 194 CLR 355 at 390.

   [23](1998) 194 CLR 355 at 390.

4. Later again, in R v Metal Trades Employers' Association; Ex parte Amalgamated Engineering Union, Australian Section[24], Dixon J referred to "imperative duties or inviolable limitations or restraints" which may be imposed by legislation, contravention of which would not be protected by a privative provision.  To describe a duty as imperative, or a restraint as inviolable, is to express the result of a process of construction, rather than a reason for adopting a particular construction; but it explains the nature of the judgment to be made.  Because what is involved is a process of statutory construction, and attempted reconciliation, the outcome will necessarily be influenced by the particular statutory context.

   [24](1951) 82 CLR 208 at 248.

5. The approach to the interpretation of statutes containing privative provisions enunciated by Dixon J in Hickman, and developed by him in later cases, has been accepted by this Court as authoritative[25]. Parliament has legislated in the light of that acceptance. That approach is inconsistent with the plaintiff's submission that s 474 should be read literally, treated as an attempted ouster of this Court's jurisdiction under s 75(v) of the Constitution, and, to that extent at least, declared invalid. In this respect, the argument for the Commonwealth prevails.

   [25]eg Deputy Commissioner of Taxation v Richard Walter Pty Ltd (1995) 183 CLR 168; Darling Casino Ltd v NSW Casino Control Authority (1997) 191 CLR 602.

6. However, the questions in the case stated deal with the operation of s 474, not in the abstract, but in its application to the proceedings for constitutional writs contemplated by the plaintiff. Those proceedings involve a challenge to a purported decision of the Tribunal on the ground of denial of procedural fairness or natural justice. Accordingly, there was argument from both parties as to the operation of the Act, including s 474, in a case of that kind.

7. In order to establish the context in which the competing arguments on statutory construction are to be considered, it is convenient to identify the issues that would arise apart from the effect of s 474. In that regard, it should be noted that, since the time relevant to this case, Parliament has enacted further legislation, which was assented to on 3 July 2002, and commenced on the following day, dealing with certain aspects of the requirements of natural justice in connection with the operation of parts of the Act[26].  That legislation is presently irrelevant.

   [26]Migration Legislation Amendment (Procedural Fairness) Act 2002 (Cth).

8. In Australian Broadcasting Tribunal v Bond[27], Deane J explained that, in the past, it was customary to refer to the duty to observe common law requirements of fairness as a duty "to act judicially".  In a passage from Hickman quoted above, Dixon J can be seen using that expression.  Later, the duty came to be referred to as a duty to observe the requirements of "natural justice".  Later again, it became common to speak of "procedural fairness".  The precise content of the requirements so described may vary according to the statutory context; and may be governed by express statutory provision.  Subject to any such statutory regulation, and relevantly for present purposes, the essential elements involved include fairness and detachment.  Fairness and detachment involve "the absence of the actuality or the appearance of disqualifying bias and the according of an appropriate opportunity of being heard"[28].  A statute may regulate and govern what is required of a tribunal or other decision-maker in these respects, and prescribe the consequences, in terms of validity or invalidity, of any departure.[29]  Subject to any such statutory provision, denial of natural justice or procedural fairness will ordinarily involve failure to comply with a condition of the exercise of decision-making power, and jurisdictional error.  In 1885, the consequences of such failure were described by Lord Selborne in Spackman v Plumstead District Board of Works[30], a case concerning the potential for judicial review of an architect's decision as to where a building line should be.  The architect's decision-making authority was conferred by statute.  His Lordship said[31] that, by directing the architect to decide the building line, the statute (by implication) imposed upon him a duty to decide it to the best of his judgment, independently and impartially. His Lordship then said[32]:

   "No doubt, in the absence of special provisions as to how the person who is to decide is to proceed, the law will imply no more than that the substantial requirements of justice shall not be violated.  He is not a judge in the proper sense of the word; but he must give the parties an opportunity of being heard before him and stating their case and their view.  He must give notice when he will proceed with the matter, and he must act honestly and impartially and not under the dictation of some other person or persons to whom the authority is not given by law.  There must be no malversation of any kind.  There would be no decision within the meaning of the statute if there were anything of that sort done contrary to the essence of justice."

9. In the present context, there is a question whether a purported decision of the Tribunal made in breach of the assumed requirements of natural justice, as alleged, is excluded from judicial review by s 474. The issue is whether such an act on the part of the Tribunal is within the scope of the protection afforded by s 474. Consistent with authority in this country, this is a matter to be decided as an exercise in statutory construction, the determinative consideration being whether, on the true construction of the Act as a whole, including s 474, the requirement of a fair hearing is a limitation upon the decision-making authority of the Tribunal of such a nature that it is inviolable. The line of reasoning developed by Dixon J in Hickman and later cases identifies the nature of the task involved, and the question to be asked.  By identifying the task as one of statutory construction, all relevant principles of statutory construction are engaged.  It cannot be suggested that Dixon J was formulating a principle of construction which excluded all others.  On the contrary, by treating the exercise as a matter of construction he was opening the way for the application of other principles as well.  Those principles have been stated by this Court on many occasions, and are as well known to Parliament as Hickman itself.

10. In considering and applying the relevant principles of statutory construction, it is necessary to begin with an examination of the scheme of the Act. For present purposes, the central provisions of the Act are those which concern the making of decisions to grant or refuse visas, which enable a non-citizen lawfully to enter, or remain in, Australia. Unlawful entry into, or presence in, Australia, exposes a person to loss of liberty and compulsory removal. The Act, and the Regulations made under it, provide for multiple classes, and sub-classes, of visa. For each class of visa detailed criteria are provided. These must be satisfied by applicants, and are to be applied by decision-makers. The plaintiff in this case applied for a protection visa. By virtue of s 36 of the Act, a criterion for a protection visa is that the applicant for the visa is a non-citizen of Australia to whom Australia has protection obligations under the Convention relating to the Status of Refugees as amended by the 1967 Refugees Protocol. That Convention includes a definition of "refugee". It is presently unnecessary to note the detail of that definition. It suffices to say that its elements have given rise to much litigation, and have been the subject of judicial interpretation in many cases. Section 65 of the Act provides that if, after considering a valid application for a visa, the Minister is satisfied that the prescribed criteria have been met, the Minister is to grant the visa. If not so satisfied, the Minister is to refuse the visa. The Minister has power to delegate this function. Decisions of the Minister or a delegate are subject to review by the Tribunal. Such a review occurred in the present case. The essence of the plaintiff's application for a visa was that he satisfied the Convention definition of a refugee, and that, pursuant to the Convention, Australia owed him protection obligations. The relevant provisions of the Act constitute the means by which Australia gives effect to its international obligations. The interpretation of the definition of refugee in the Convention is a matter of law. Decisions as to whether a person is someone to whom Australia owes protection obligations often turn upon questions of law; sometimes complex and difficult questions of law. Although it is the provisions of the Act concerning protection visas that are directly relevant in the present case, they are only part of a wider, and more detailed, pattern of legislation which, in a variety of respects, affects fundamental human rights and involves Australia's international obligations.

11. In such a context, the following established principles are relevant to the resolution of the question of statutory construction.

12. First, where legislation has been enacted pursuant to, or in contemplation of, the assumption of international obligations under a treaty or international convention, in cases of ambiguity a court should favour a construction which accords with Australia's obligations[33].

    [33]Minister for Immigration and Ethnic Affairs v Teoh (1995) 183 CLR 273 at 287 per Mason CJ and Deane J; see also Chu Kheng Lim v Minister for Immigration (1992) 176 CLR 1 at 38 per Brennan, Deane and Dawson JJ.

13. Secondly, courts do not impute to the legislature an intention to abrogate or curtail fundamental rights or freedoms unless such an intention is clearly manifested by unmistakable and unambiguous language.  General words will rarely be sufficient for that purpose.  What courts will look for is a clear indication that the legislature has directed its attention to the rights or freedoms in question, and has consciously decided upon abrogation or curtailment[34].  As Lord Hoffmann recently pointed out in the United Kingdom[35], for Parliament squarely to confront such an issue may involve a political cost, but in the absence of express language or necessary implication, even the most general words are taken to be "subject to the basic rights of the individual"[36].

    [34]Coco v The Queen (1994) 179 CLR 427 at 437 per Mason CJ, Brennan, Gaudron and McHugh JJ.

    [35]R v Home Secretary; Ex parte Simms [2000] 2 AC 115 at 131.

    [36]See also Annetts v McCann (1990) 170 CLR 596 at 598 per Mason CJ, Deane and McHugh JJ.

14. Thirdly, the Australian Constitution is framed upon the assumption of the rule of law[37].  Brennan J said[38]:

    "Judicial review is neither more nor less than the enforcement of the rule of law over executive action; it is the means by which executive action is prevented from exceeding the powers and functions assigned to the executive by law and the interests of the individual are protected accordingly."

    [37]Australian Communist Party v The Commonwealth (1951) 83 CLR 1 at 193 per Dixon J.

    [38]Church of Scientology v Woodward (1982) 154 CLR 25 at 70.

15. Fourthly, and as a specific application of the second and third principles, privative clauses are construed "by reference to a presumption that the legislature does not intend to deprive the citizen of access to the courts, other than to the extent expressly stated or necessarily to be implied"[39].

    [39]Public Service Association (SA) v Federated Clerks' Union (1991) 173 CLR 132 at 160 per Dawson and Gaudron JJ.

16. Fifthly, a principle of relevance to Hickman is that what is required is a consideration of the whole Act, and an attempt to achieve a reconciliation between the privative provision and the rest of the legislation. In the case of the Act presently under consideration, that is a formidable task. There may not be a single answer to the question. But the task is not to be performed by reading the rest of the Act as subject to s 474, or by making s 474 the central and controlling provision of the Act.

17. The Commonwealth's argument as to the effect of s 474, in its application to the proceedings contemplated by the plaintiff, is inconsistent with the above principles. In essence, the argument is that the amendment of the Act which introduced s 474 brought about a radical transformation of the pre-existing provisions. From that time, there were no "imperative duties", and no "inviolable limitations" on the powers and jurisdiction of decision-makers under the Act. When s 474 says that constitutional writs do not lie, it means that, subject to "the Hickman conditions", breaches of the Act do not involve jurisdictional error. The "Hickman conditions" are that a decision is a bona fide attempt to exercise power, that it relates to the subject matter of the legislation, and that is reasonably capable of reference to the power. Applying that to a decision to refuse a protection visa under s 65 of the Act, it will always necessarily relate to the subject matter of the legislation, it will always be reasonably capable of reference to power given to the decision-maker, and so long as it is a bona fide attempt to exercise the power conferred by s 65, all the conditions necessary for legally valid decision-making will have been satisfied. Australia's international protection obligations will be fulfilled by the executive government's bona fide attempt to fulfil them.

18. The theory behind this argument appears to be that, in whatever statutory context it is found, a privative provision controls the meaning of the remainder of the statute, and, in the case of a conferral of jurisdiction upon a decision-maker, expands that jurisdiction in such a way that excess of jurisdiction will only occur in the event of a breach of one of the "conditions" mentioned.  That is difficult to reconcile with the actual decision in Hickman. And, in the context of the Act, and decisions as to protection visas, it is impossible to reconcile with the principles of statutory construction stated above.

19. As French J observed in NAAV v Minister for Immigration and Multicultural and Indigenous Affairs[40], the Act is "replete with official powers and discretions, tightly controlled under the Act itself and under the Regulations by conditions and criteria to be satisfied before those powers and discretions can be exercised". In that case, and a number of related cases heard at the same time, the Full Court of the Federal Court dealt with several different kinds of challenge to decisions under the Act, and the operation of s 474 in relation to each of them. Here we are concerned with only one kind of challenge, involving a claim of denial of natural justice. A rejection of the Commonwealth's global approach to the operation of s 474 does not mean that the opposite conclusion follows in relation to every possible kind of challenge to a decision.

    [40](2002) 193 ALR 449 at 542 [399].

20. The principles of statutory construction stated above lead to the conclusion that Parliament has not evinced an intention that a decision by the Tribunal to confirm a refusal of a protection visa, made unfairly, and in contravention of the requirements of natural justice, shall stand so long as it was a bona fide attempt to decide whether or not such a visa should be granted. Decision-makers, judicial or administrative, may be found to have acted unfairly even though their good faith is not in question. People whose fundamental rights are at stake are ordinarily entitled to expect more than good faith. They are ordinarily entitled to expect fairness. If Parliament intends to provide that decisions of the Tribunal, although reached by an unfair procedure, are valid and binding, and that the law does not require fairness on the part of the Tribunal in order for its decisions to be effective under the Act, then s 474 does not suffice to manifest such an intention.

1. It follows that, in my view, if the Tribunal's decision in relation to the plaintiff was taken in breach of the rules of natural justice, as is alleged, then it is not within the scope of protection afforded by s 474. It is not, relevantly, a decision to which s 474 applies.

   Section 486A

2. As to s 486A, three features of the section may be noted. First, it applies in relation to a "privative clause decision", which is defined in s 5 to mean a decision of the kind referred to in s 474(2). Secondly, the time limit commences to run from notification of the decision, which may be very different from the time when a person becomes aware of the circumstances giving rise to a possible challenge to the decision. Thirdly, the time limit must not be extended. Even on the Commonwealth's submissions as to the meaning and effect of s 474, there may be decisions which that section does not protect. A decision procured by a corrupt inducement would be an obvious instance. The inducement might not be discovered until a time later than 35 days after the notification of the decision. How does the legislation operate in such a case? That is not a question that arises in the present case.

3. The Commonwealth contends that the meaning and effect of s 486A is that decisions of the kind described in s 474(2), unless challenged within the time limited by s 486A, are to be treated as valid and effective for all purposes, even if they are affected by error of a kind which, consistently with "the Hickman principles" would not be protected from judicial review by s 474. Thus, for example, if the Regulations in question in Hickman had included, not merely reg 17, but also a regulation in terms similar to s 486A, reg 17 would not defeat an application for prohibition but, if the time limit elapsed before proceedings were commenced, the additional regulation would bar the proceedings.

4. That approach involves treating "decision ... under this Act" in s 474(2) as meaning "purported decision ... under this Act"; but if that were correct, it appears to leave no textual basis for the hypothesis that s 474 does not, of its own force, protect the decision from judicial review. Whatever term is used to describe, in a summary form, the kinds of error that expose a decision to judicial review, notwithstanding a privative provision, the process of statutory construction involved cannot lead to "decision" being read as "purported decision". If a decision is not treated as a "decision ... under this Act" for the purposes of s 474, it is not such a decision for the purposes of s 486A.

5. It is to be noted that s 474 does not apply only to decisions that have been made. It also covers a failure or refusal to make a decision, conduct preparatory to the making of a decision, and other acts or omissions which may not involve something that is a purported decision, but not a decision under the Act. The operation of s 486A in such a case does not arise for decision. In the present case, s 486A will not operate in relation to a purported decision made in breach of the requirements of natural justice.

   Conclusion

6. I would answer the questions in the case stated in the manner proposed in the joint judgment.

7. GAUDRON, McHUGH, GUMMOW, KIRBY AND HAYNE JJ.   The plaintiff commenced proceedings in this Court by writ of summons endorsed with his statement of claim.  He contends that certain provisions of the Migration Act 1958 (Cth) ("the Act") are invalid. The provisions in question bear on his right to seek judicial review of a decision of the Refugee Review Tribunal ("the decision") affirming an earlier decision of the delegate of the Minister for Immigration and Multicultural and Indigenous Affairs refusing his application for a protection visa. By reason that he brings these proceedings in his capacity as a person who applied for a protection visa under s 36 of the Act, the plaintiff cannot be named by this Court[41].

   [41]Section 91X of the Act relevantly provides:

   "(1)This section applies to a proceeding before the High Court, the Federal Court or the Federal Magistrates Court if the proceeding relates to a person in the person's capacity as:

   (a)    a person who applied for a protection visa; ...

   (2)The court must not publish (in electronic form or otherwise), in relation to the proceeding, the person's name."

   In the absence of any direct challenge, it will be assumed that s 91X is constitutionally valid.

8. After the defendant, the Commonwealth of Australia, filed its defence to the plaintiff's statement of claim, Gummow J stated a case for the consideration of the Full Court.  At this stage, it is necessary only to note that the following is recorded in the case stated:

   "The Plaintiff asserts that he would have applied and would, but for sections 474 and 486A of the Migration Act 1958 (Cth), apply to the High Court for judicial review of and for relief in its original jurisdiction under section 75(v) of the Constitution of the decision."

   A draft Order Nisi attached to the case stated reveals that he would have challenged, or would challenge, the decision on the ground that it was reached in breach of the requirements of natural justice and would have sought, or would seek, relief by way of prohibition, certiorari and mandamus, but not by way of injunction. Breaches of the requirements of natural justice found a complaint of jurisdictional error under s 75(v) of the Constitution[42].

   [42]Re Refugee Review Tribunal; Ex parte Aala (2000) 204 CLR 82. It is unnecessary in these proceedings to consider any consequences that may follow from the Migration Legislation Amendment (Procedural Fairness) Act 2002 (Cth) which came into force, and applies to decisions made, after the decisions relevant to these proceedings.

   Questions in the case stated

9. By reference to the facts and matters therein set out, which are briefly recorded above, the following questions are asked in the case stated:

   "QUESTION 1

   Is section 486A of the Migration Act 1958 (Cth) invalid in respect of an application by the Plaintiff to the High Court of Australia for relief under section 75(v) of the Constitution?

   QUESTION 2

   Is section 474 of the Migration Act 1958 (Cth) invalid in respect of an application by the Plaintiff to the High Court of Australia for relief under section 75(v) of the Constitution?

   QUESTION 3

   By whom should the costs of the proceeding in this Honourable Court be borne?"

10. As the draft Order Nisi attached to the case stated does not claim injunctive relief, Questions 1 and 2 above should be answered by reference only to the writs of mandamus, certiorari and prohibition.

    Legislative provisions in issue

11. Section 474 was inserted into the Act by Sched 1 of the Migration Legislation Amendment (Judicial Review) Act 2001 (Cth) ("the Amending Act") which came into operation on 2 October 2001. That section relevantly provides:

    "(1)     A privative clause decision:

    (a)      is final and conclusive; and

    (b)must not be challenged, appealed against, reviewed, quashed or called in question in any court; and

    (c)is not subject to prohibition, mandamus, injunction, declaration or certiorari in any court on any account.

    (2)In this section:

    privative clause decision means a decision of an administrative character made, proposed to be made, or required to be made, as the case may be, under this Act or under a regulation or other instrument made under this Act (whether in the exercise of a discretion or not), other than a decision referred to in subsection (4) or (5).

    (3)A reference in this section to a decision includes a reference to the following:

    (a)granting, making, suspending, cancelling, revoking or refusing to make an order or determination;

    (b)granting, giving, suspending, cancelling, revoking or refusing to give a certificate, direction, approval, consent or permission (including a visa);

    (c)granting, issuing, suspending, cancelling, revoking or refusing to issue an authority or other instrument;

    (d)imposing, or refusing to remove, a condition or restriction;

    (e)making or revoking, or refusing to make or revoke, a declaration, demand or requirement;

    (f)retaining, or refusing to deliver up, an article;

    (g)doing or refusing to do any other act or thing;

    (h)conduct preparatory to the making of a decision, including the taking of evidence or the holding of an inquiry or investigation;

    (i)a decision on review of a decision, irrespective of whether the decision on review is taken under this Act or a regulation or other instrument under this Act, or under another Act;

    (j)a failure or refusal to make a decision."

    Sub-section (4) then sets out certain decisions that, for the purposes of s 474(2), are not privative clause decisions. And sub-s (5) permits the making of regulations specifying that particular decisions are not privative clause decisions.

12. As will later appear, there may be a question whether the decision which the plaintiff wishes to challenge is a "privative clause decision" as defined in sub-ss (2) and (3) of the Act. However, if it is, it is common ground that neither sub-ss (4) nor (5) operates to take the decision outside of the definition in sub-ss (2) and (3) of s 474.

13. Section 486A of the Act was amended by the Migration Legislation Amendment Act (No 1) 2001 (Cth) which came into operation on 27 September 2001 and by the Migration Legislation Amendment (Judicial Review) Act 2001 (Cth), which came into operation on 2 October 2001. It now reads as follows:

    "(1)An application to the High Court for a writ of mandamus, prohibition or certiorari or an injunction or a declaration in respect of a privative clause decision must be made to the High Court within 35 days of the actual (as opposed to deemed) notification of the decision.

    (2)The High Court must not make an order allowing, or which has the effect of allowing, an applicant to make an application mentioned in subsection (1) outside that 35 day period.

    (3)The regulations may prescribe the way of notifying a person of a decision for the purposes of this section."

14. The plaintiff was notified of the decision on 5 April 2002, more than 35 days before commencing these proceedings.

    The competing arguments with respect to s 474 of the Act

15. Although it is the subject of the second question in the case stated, it is convenient to consider s 474 of the Act first. The argument advanced on behalf of the plaintiff is that par (c) of s 474(1) is directly inconsistent with s 75(v) of the Constitution which confers original jurisdiction on this Court "[i]n all matters ... in which a writ of Mandamus or prohibition or an injunction is sought against an officer of the Commonwealth". That being so, it is said, s 474(1)(c) is invalid. Further, it is put that the other parts of s 474 are inseverable from sub-s (1)(c) and, thus, are also invalid.

16. On behalf of the Commonwealth, it was conceded that s 474 cannot oust the jurisdiction which s 75(v) of the Constitution confers on this Court. That concession was properly made. It reflects what has been understood to be the position since the decision in The Tramways Case [No 1][43] given in 1914, and what follows is to be read with that starting point in mind. However, it was submitted that, when the Act is construed as a whole, s 474 does not have that effect and, thus, is not invalid. It will later be necessary to refer in some detail to the construction which, according to the submissions for the Commonwealth, should be placed on relevant provisions of the Act and the effect which s 474 is said to have on this Court's power to review decisions pursuant to s 75(v) of the Constitution. For the moment, however, it is sufficient to note that it is necessary to engage in a process of construction before the constitutional validity of s 474 can be considered.

    [43]R v The Commonwealth Court of Conciliation and Arbitration; Ex parte The Brisbane Tramways Company Limited (1914) 18 CLR 54.

    Section 474 of the Act; privative clauses generally

17. The construction of legislation containing provisions such as s 474 of the Act has a particular, but not entirely satisfactory, history. For the moment, it is necessary to refer only to the decision in R v Hickman; Ex parte Fox and Clinton[44]. Doubtless because of that decision and, also, because of the terms of s 75(v) of the Constitution, the Commonwealth contends that s 474(1) is not to be construed as totally excluding judicial review. Moreover, it is clear that Parliament did not intend it to have that effect.

    [44](1945) 70 CLR 598.

18. So far as legislative intent is concerned, it is relevant to note that, in the second reading speech for the Bill that became the Amending Act which amended the Act so to include s 474, the Minister said:

    "          The privative clause does not mean that access to the courts is denied, nor that only the High Court can hear migration matters.  Both the Federal Court and the High Court can hear migration matters, but the grounds of judicial review before either court have been limited."[45]

    A little later, the Minister added:

    "          Members may be aware that the effect of a privative clause such as that used in Hickman's case is to expand the legal validity of the acts done and the decisions made by decision makers.  The result is to give decision makers wider lawful operation for their decisions, and this means that the grounds on which those decisions can be challenged in the Federal and High Courts are narrower than currently."[46]

    Of course, the Minister's understanding of the decision in Hickman cannot give s 474 an effect that is inconsistent with the terms of the Act as a whole[47].

19. In Hickman, a question arose as to the effect of reg 17 of the National Security (Coal Mining Industry Employment) Regulations 1941 (Cth), made under the National Security Act 1939 (Cth) and thus supported by the defence power. Regulation 17 provided that a decision of a Local Reference Board, which had a general power to settle disputes as to any local matter likely to affect the amicable relations of employers and employees in the coal mining industry[48], "[should] not be challenged, appealed against, quashed or called into question, or be subject to prohibition, mandamus or injunction, in any court on any account whatever"[49]. Dixon J said of reg 17:

    " The particular regulation is expressed in a manner that has grown familiar. Both under Commonwealth law, and in jurisdictions where there is a unitary constitution, the interpretation of provisions of the general nature of reg 17 is well established. They are not interpreted as meaning to set at large the courts or other judicial bodies to whose decision they relate. Such a clause is interpreted as meaning that no decision which is in fact given by the body concerned shall be invalidated on the ground that it has not conformed to the requirements governing its proceedings or the exercise of its authority or has not confined its acts within the limits laid down by the instrument giving it authority, provided always that its decision is a bona fide attempt to exercise its power, that it relates to the subject matter of the legislation, and that it is reasonably capable of reference to the power given to the body."[50]

    [49]Regulation 17.

    [50](1945) 70 CLR 598 at 614-615.

20. It should be noted at once that, in the passage last quoted, Dixon J was not speaking of reg 17, but of privative clauses generally. Even so, it is important to appreciate that his Honour's observations were confined to "decision[s] ... in fact given"[51].  Moreover and as later decisions of this Court have made clear, the expression "reasonably capable of reference to the power given to the body"[52], has been treated as signifying that it must "not on its face go beyond ... power"[53].  Thus, even on this general statement, a privative clause cannot protect against a failure to make a decision required by the legislation in which that clause is found or against a decision which, on its face, exceeds jurisdiction.

See also O'Toole v Charles David Pty Ltd (1991) 171 CLR 232 at 287 per Deane, Gaudron and McHugh JJ.

21. As to the effect of the privative clause actually considered in Hickman, Dixon J first noted that the Parliament could neither "give power to any judicial or other authority" in excess of constitutional power nor "impose limits upon the ... authority of a body ... with the intention that any excess of that authority means invalidity, and ... at the same time ... deprive this Court of authority to restrain the invalid action ... by prohibition."[54]  Rather, if legislation purports to impose limits on authority and contains a privative clause, it is, so his Honour said, "a question of interpretation of the whole legislative instrument whether transgression of the limits, so long as done bona fide and bearing on its face every appearance of an attempt to pursue the power, necessarily spells invalidity."[55]  And in that process, according to his Honour, an attempt should be made to "reconcile" the apparently conflicting legislative provisions[56].

    [55](1945) 70 CLR 598 at 616.

    [56](1945) 70 CLR 598 at 616.

22. The reconciliation of the conflicting provisions effected by Dixon J in Hickman was expressed in these terms:

    "the decisions of a Reference Board should not be considered invalid if they do not upon their face exceed the Board's authority and if they do amount to a bona fide attempt to exercise the powers of the Board and relate to the subject matter of the Regulations"[57].

    In the result, prohibition issued with respect to the decision under challenge in that case as, on its face, it exceeded the Board's authority.

    [57](1945) 70 CLR 598 at 617.

23. It follows from Hickman, and it is made clear by subsequent cases[58], that the so-called "Hickman principle" is simply a rule of construction allowing for the reconciliation of apparently conflicting statutory provisions.  Once this is accepted, as it must be, it follows that there can be no general rule as to the meaning or effect of privative clauses.  Rather, the meaning of a privative clause must be ascertained from its terms; and if that meaning appears to conflict with the provision pursuant to which some action has been taken or some decision made, its effect will depend entirely on the outcome of its reconciliation with that other provision.

    [58]See R v Coldham; Ex parte Australian Workers' Union (1983) 153 CLR 415; O'Toole v Charles David Pty Ltd (1991) 171 CLR 232; Deputy Commissioner of Taxation v Richard Walter Pty Ltd (1995) 183 CLR 168 at 193-195 per Brennan J; Darling Casino Ltd v NSW Casino Control Authority (1997) 191 CLR 602.

    Privative clauses and the process of reconciling legislative provisions

24. It was said in R v Coldham; Ex parte Australian Workers' Union that, where there is an inconsistency between a privative clause and other statutory provisions:

    "The inconsistency is resolved by reading the two provisions together and giving effect to each.  The privative clause is taken into account in ascertaining what the apparent restriction or restraint actually signifies in order to determine whether the situation is one in which prohibition lies."[59]

    As a general statement, so much may be accepted.  However, it provides little guidance as to the manner in which a privative clause is taken into account or the light it sheds on the restriction or restraint in question.

    [59](1983) 153 CLR 415 at 418 per Mason ACJ and Brennan J.

1. On behalf of the Commonwealth, it was contended that s 474 should first be construed as meaning and intended to mean that decisions are protected so long as there has been a bona fide attempt to exercise the power in question, that they relate to the subject-matter of the legislation and are reasonably capable of reference to the power. Then it is said that, being a later provision than those by which particular powers are conferred, s 474 should be construed as impliedly repealing all limitations on those powers leaving only constitutional limitations and those which derive from s 474. In terms, the argument was that s 474 "enlarges the powers of decision-makers so that their decisions are valid so long as they comply with the three Hickman provisos".

2. It might be thought that the first step of the argument for the Commonwealth finds some support in what was said by Dixon J in R v Murray; Ex parte Proctor[60].  In that case, his Honour said as to the reconciliation of apparently inconsistent legislative provisions:

   "The first step in such a process of interpretation is to apply to a [privative clause] provision ... the traditional or established interpretation which makes the protection it purports to afford inapplicable unless there has been an honest attempt to deal with a subject matter confided to the tribunal and to act in pursuance of the powers of the tribunal in relation to something that might reasonably be regarded as falling within its province"[61].

   [60](1949) 77 CLR 387.

   [61](1949) 77 CLR 387 at 399-400.

3. A proper reading of what Dixon J said in Murray is not that a privative clause is construed as meaning that decisions are protected so long as they conform to "the three Hickman provisos".  Rather, the position is that the "protection" which the privative clause "purports to afford"[62] will be inapplicable unless those provisos are satisfied.  And to ascertain what protection a privative clause purports to afford, it is necessary to have regard to the terms of the particular clause in question[63].  Thus, contrary to the submissions for the Commonwealth, it is inaccurate to describe the outcome in a situation where the provisos are satisfied as an "expansion" or "extension" of the powers of the decision-makers in question.

   [63]See Darling Casino Ltd v NSW Casino Control Authority (1997) 191 CLR 602 at 633-635 per Gaudron and Gummow JJ.

4. There are other difficulties with the argument for the Commonwealth.  The process of construction for which it contends is not a process of construing the legislation as a whole.  It is a process which places a construction on one provision, the privative clause, and asserts that all other provisions may be disregarded.  That process ignores what Dixon J said in Murray was a "second step in [the process of] interpreting the whole legislative instrument"[64], namely:

   "to consider whether particular limitations on power and specific requirements as to the manner in which the tribunal shall be constituted or shall exercise its power are so expressed that they must be taken to mean that observance of the limitations and compliance with the requirements are essential to valid action."[65]

   His Honour explained that:

   "a clearly expressed specific intention of [that] kind can hardly give way to the general intention indicated by ... a [privative clause]"[66].

5. The importance of giving effect to express legislative provisions, notwithstanding the existence of a privative clause, is to be seen in Coldham[67]. In that case, it was contended that the privative clause contained in s 60(1) of the Conciliation and Arbitration Act 1904 (Cth) protected a decision under s 142A(1) of that Act. The latter provision authorised the making of an order that an organisation of employees should have the exclusive right to represent some or all of the industrial interests of a class or group of employees who were "eligible for membership of the organization"[68].  It was said by Mason ACJ and Brennan J that s 60 "[could not] affect the operation of a provision which impose[d] inviolable limitations or restraints upon ... jurisdiction or powers"[69].  In this regard, the requirement that persons be "eligible for membership of the organization" was said to be "quite explicit" and, thus, an inviolable jurisdictional restraint[70].

6. So far as it was contended on behalf of the Commonwealth that s 474 effected an implied repeal of statutory limitations on authority or powers conferred by the Act, the argument seeks to give s 474 an effect which was denied in Coldham and which exceeds anything that was said in Hickman.  And because it exceeds anything that was said in Hickman, by reference to which the Minister explained the effect of s 474 in the second reading speech for the Bill that became the Amending Act, it is impossible to conclude that the Parliament intended to effect a repeal of all statutory limitations or restraints upon the exercise of power or the making of a decision.

7. More fundamentally, the method of reconciliation by implied repeal of limitations or restraints in the Act on the exercise of power must be rejected because it seeks to give to s 474 a meaning which its terms cannot bear. It seeks to give to that section a meaning that is descriptive of a recognised limitation on the effectiveness of privative clauses generally and ignores the words of the section which, in terms, limit access to the courts. Accordingly, the argument that s 474 effected an implied repeal of all statutory limitations and restraints must be rejected.

8. Although s 474 does not purport to effect a repeal of statutory limitations or restraints, it should be noted that it may be that, by reference to the words of s 474, some procedural or other requirements laid down by the Act are to be construed as not essential to the validity of a decision[71].  However, that is a matter that can only be determined by reference to the requirement in issue in a particular case.

9. Of course, the process of reconciliation elaborated by Dixon J in Murray which may result in some procedural or other requirement being construed as not essential to the validity of an act or decision, is necessary only if there is an apparent conflict between the provisions which impose those requirements and the privative clause in question[72].  Thus, if reliance is placed on a privative clause, the first step must be to ascertain its meaning or, as Dixon J put it in Murray, to ascertain "the protection it purports to afford"[73].

   Construction of s 474 of the Act

10. There are two basic rules of construction which apply to the interpretation of privative clauses. The first, which applies in the case of privative clauses in legislation enacted by the Parliament of the Commonwealth, is that "if there is an opposition between the Constitution and any such provision, it should be resolved by adopting [an] interpretation [consistent with the Constitution if] that is fairly open."[74]

    [74]R v Hickman; Ex parte Fox and Clinton (1945) 70 CLR 598 at 616 per Dixon J. See generally with respect to the rule that, if possible, legislative provisions should be construed conformably with the Constitution: Ex parte Walsh and Johnson; In re Yates (1925) 37 CLR 36 at 61-62 per Knox CJ, 127 per Rich J, 138 per Starke J; Pidoto v Victoria (1943) 68 CLR 87 at 109 per Latham CJ; R v Director-General of Social Welfare (Vict); Ex parte Henry (1975) 133 CLR 369 at 374 per Gibbs J; Russell v Russell (1976) 134 CLR 495 at 542 per Mason J; Bourke v State Bank of New South Wales (1990) 170 CLR 276 at 291; Re Nolan; Ex parte Young (1991) 172 CLR 460 at 485-486 per Brennan and Toohey JJ; Re Dingjan; Ex parte Wagner (1995) 183 CLR 323 at 339 per Brennan J; Victoria v The Commonwealth (Industrial Relations Act Case) (1996) 187 CLR 416 at 501-503 per Brennan CJ, Toohey, Gaudron, McHugh and Gummow JJ; Wilson v Minister for Aboriginal and Torres Strait Islander Affairs (1996) 189 CLR 1 at 10 per Brennan CJ, Dawson, Toohey, McHugh and Gummow JJ, 26 per Gaudron J; R v Hughes (2000) 202 CLR 535 at 556-557 [43] per Gleeson CJ, Gaudron, McHugh, Gummow, Hayne and Callinan JJ, 560-561 [53] per Kirby J; Re Patterson; Ex parte Taylor (2001) 207 CLR 391 at 494-495 [310] per Kirby J; Acts Interpretation Act 1901 (Cth), s 15A.

11. The second basic rule, which applies to privative clauses generally, is that it is presumed that the Parliament does not intend to cut down the jurisdiction of the courts save to the extent that the legislation in question expressly so states or necessarily implies[75].  Accordingly, privative clauses are strictly construed.

    [75]Public Service Association (SA) v Federated Clerks' Union (1991) 173 CLR 132 at 160 per Dawson and Gaudron JJ. See also Darling Casino Ltd v NSW Casino Control Authority (1997) 191 CLR 602; Shergold v Tanner (2002) 76 ALJR 808 at 812 [27] per Gleeson CJ, McHugh, Gummow, Kirby and Hayne JJ; 188 ALR 302 at 307.

12. Quite apart from s 75(v), there are other constitutional requirements that are necessarily to be borne in mind in construing a provision such as s 474 of the Act. A privative clause cannot operate so as to oust the jurisdiction which other paragraphs of s 75 confer on this Court, including that conferred by s 75(iii) in matters "in which the Commonwealth, or a person suing or being sued on behalf of the Commonwealth, is a party". Further, a privative clause cannot operate so as to allow a non-judicial tribunal or other non-judicial decision-making authority to exercise the judicial power of the Commonwealth[76].  Thus, it cannot confer on a non-judicial body the power to determine conclusively the limits of its own jurisdiction.  So much is clear from the observation of Mason ACJ and Brennan J in Coldham that they were "unable to perceive how the Commission could be given authority to determine conclusively the question [upon which its jurisdiction depended] consistently with its character as a body which does not exercise the judicial power of the Commonwealth."[77]

    [77](1983) 153 CLR 415 at 419. See also at 426-428 per Deane and Dawson JJ.

13. As previously indicated, it was argued on behalf of the plaintiff that s 474(1)(c) of the Act is directly inconsistent with s 75(v) of the Constitution. However, s 474(1)(c) cannot be read in isolation from the definition of "privative clause decision" in s 474(2). That definition relevantly confines "privative clause decision[s]" to decisions "made, proposed to be made, or required to be made ... under this Act".

14. When regard is had to the phrase "under this Act" in s 474(2) of the Act, the words of that sub-section are not apt to refer either to decisions purportedly made under the Act or, as some of the submissions made on behalf of the Commonwealth might suggest, to decisions of the kind that might be made under the Act. Moreover, if the words of the sub-section were to be construed in either of those ways, s 474(1)(c) would be in direct conflict with s 75(v) of the Constitution and, thus, invalid. Further, they would confer authority on a non-judicial decision-maker of the Commonwealth to determine conclusively the limits of its own jurisdiction and, thus, at least in some cases, infringe the mandate implicit in the text of Ch III of the Constitution that the judicial power of the Commonwealth be exercised only by the courts named and referred to in s 71.

15. Once it is accepted, as it must be, that s 474 is to be construed conformably with Ch III of the Constitution, specifically, s 75, the expression "decision[s] ... made under this Act" must be read so as to refer to decisions which involve neither a failure to exercise jurisdiction nor an excess of the jurisdiction conferred by the Act. Indeed so much is required as a matter of general principle. This Court has clearly held that an administrative decision which involves jurisdictional error is "regarded, in law, as no decision at all"[78].  Thus, if there has been jurisdictional error because, for example, of a failure to discharge "imperative duties"[79] or to observe "inviolable limitations or restraints"[80], the decision in question cannot properly be described in the terms used in s 474(2) as "a decision ... made under this Act" and is, thus, not a "privative clause decision" as defined in ss 474(2) and (3) of the Act[81].

16. To say that a decision that involves jurisdictional error is not "a decision ... made under [the] Act" is not to deny that it may be necessary to engage in the reconciliation process earlier discussed to ascertain whether the failure to observe some procedural or other requirement of the Act constitutes an error which has resulted in a failure to exercise jurisdiction or in the decision-maker exceeding its jurisdiction.

17. The effect of s 474 is to require an examination of limitations and restraints found in the Act. There will follow the necessity, if s 474 is constitutionally valid and if proceedings are brought by the plaintiff in accordance with the draft Order Nisi, to determine, in those proceedings, whether, as a result of the reconciliation process, the decision of the Tribunal does or does not involve jurisdictional error and, accordingly, whether it is or is not a "privative clause decision" as defined in s 474(2) of the Act.

    Constitutional validity of s 474 of the Act

18. Before turning to the constitutional validity of s 474 of the Act in its application to the proceeding which the plaintiff would commence or would have commenced in respect of the decision of the Refugee Review Tribunal, it is important to note two matters with respect to s 75(v) of the Constitution. The first is that that provision makes no mention of certiorari which lies to quash the decisions of inferior courts and tribunals for error of law on the face of the record[82].

    [82]See R v Cook; Ex parte Twigg (1980) 147 CLR 15 at 32 per Aickin J; R v Marshall; Ex parte Federated Clerks Union of Australia (1975) 132 CLR 595 at 609 per Mason J; O'Toole v Charles David Pty Ltd (1991) 171 CLR 232 at 270 per Brennan J; Re Refugee Review Tribunal; Ex parte Aala (2000) 204 CLR 82 at 90-91 [14] per Gaudron and Gummow JJ; Re McBain; Ex parte Australian Catholic Bishops Conference (2002) 76 ALJR 694 at 725 [165] per Kirby J; 188 ALR 1 at 43-44.

19. Notwithstanding that s 75(v) does not refer to certiorari, it has long been accepted that certiorari may issue as ancillary to the constitutional writs of mandamus and prohibition[83].  However, following the decision in Re McBain; Ex parte Australian Catholic Bishops Conference, it must also be accepted that, subject to the existence of "a matter", certiorari may also issue in the exercise of jurisdiction conferred by s 75(iii) of the Constitution in "all matters ... in which the Commonwealth, or a person suing or being sued on behalf of the Commonwealth, is a party" and that conferred pursuant to s 76(i) of the Constitution "in any matter ... arising under [the] Constitution, or involving its interpretation"[84].  Thus it may be that, at least in some matters, judicial review of administrative decisions has not been and, in the absence of a privative clause having that effect, is not confined by the notion of jurisdictional error.

    [84](2002) 76 ALJR 694; 188 ALR 1.

20. As no constitutional provision confers jurisdiction with respect to certiorari, it is open to the Parliament to legislate so as to prevent the grant of such relief. However, because "privative clause decision" is relevantly defined in terms of a "decision ... made under [the] Act", s 474(1)(c) does not prevent the issue of certiorari as ancillary to mandamus or prohibition, but validly does so for non-jurisdictional error of law on the face of the record.

21. The other aspect of s 75(v) that should be noted is its conferral of jurisdiction in matters in which "an injunction is sought against an officer of the Commonwealth". Given that prohibition and mandamus are available only for jurisdictional error[85], it may be that injunctive relief is available on grounds that are wider than those that result in relief by way of prohibition and mandamus.  In any event, injunctive relief would clearly be available for fraud, bribery, dishonesty or other improper purpose.  The Hickman requirement that a decision be made bona fide presumably has the consequence that s 474 permits review in all such cases[86]. If it does not, there must, to that extent, be a real question as to the constitutional validity of s 474. However, as the draft Order Nisi indicates that relief would be or would have been sought only by way of prohibition, certiorari and mandamus, those questions need not now be explored.

    [85]Re Refugee Review Tribunal; Ex parte Aala (2000) 204 CLR 82.

    [86]cf O'Toole v Charles David Pty Ltd (1991) 171 CLR 232 at 286-287 per Deane, Gaudron and McHugh JJ where the view was expressed that the question of bona fides is to be determined solely by reference to the record and not by reference to subjective considerations. Dawson J at 305 and Toohey J at 309 expressed the view that the question of bona fides is to be determined by reference to considerations personal to the decision-maker.

22. Because, as this Court has held, the constitutional writs of prohibition and mandamus are available only for jurisdictional error and because s 474 of the Act does not protect decisions involving jurisdictional error, s 474 does not, in that regard conflict with s 75(v) of the Constitution and, thus, is valid in its application to the proceedings which the plaintiff would initiate. The plaintiff asserts jurisdictional error by reason of a denial to him of procedural fairness and thus s 474, whilst valid, does not upon its true construction protect the decision of which the plaintiff complains. A decision flawed for reasons of a failure to comply with the principles of natural justice is not a "privative clause decision" within s 474(2) of the Act.

    Section 486A of the Act: the competing arguments

1. His Honour's statement derives to some extent at least from what was held in Colonial Bank of Australasia v Willan[136].  There, Sir James W Colvile, speaking for the Privy Council, which had before it a Victorian Act containing a privative clause, said[137]:

   "It is, however, scarcely necessary to observe that the effect of this is not absolutely to deprive the Supreme Court of its power to issue a writ of certiorari to bring up the proceedings of the inferior Court, but to control and limit its action on such writ.  There are numerous cases in the books which establish that, notwithstanding the privative clause in a statute, the Court of Queen's Bench will grant a certiorari; but some of those authorities establish, and none are inconsistent with, the proposition that in any such case that Court will not quash the order removed, except upon the ground either of a manifest defect of jurisdiction in the tribunal that made it, or of manifest fraud in the party procuring it."

   [136](1874) LR 5 PC 417.

   [137](1874) LR 5 PC 417 at 442.

2. And a little later his Lordship described the minimum requirements of a due exercise of jurisdiction[138]:

   "In order to determine the first it is necessary to have a clear apprehension of what is meant by the term 'want of jurisdiction'.  There must, of course, be certain conditions on which the right of every tribunal of limited jurisdiction to exercise that jurisdiction depends.  But those conditions may be founded either on the character and constitution of the tribunal, or upon the nature of the subject-matter of the inquiry, or upon certain proceedings which have been made essential preliminaries to the inquiry, or upon facts or a fact to be adjudicated upon in the course of the inquiry.  It is obvious that conditions of the last differ materially from those of the three other classes.  Objections founded on the personal incompetency of the Judge, or on the nature of the subject-matter, or on the absence of some essential preliminary, must obviously, in most cases, depend upon matters which, whether apparent on the face of the proceedings or brought before the superior Court by affidavit, are extrinsic to the adjudication impeached.  But an objection that the Judge has erroneously found a fact which, though essential to the validity of his order, he was competent to try, assumes that, having general jurisdiction over the subject-matter, he properly entered upon the inquiry, but miscarried in the course of it.  The superior Court cannot quash an adjudication upon such an objection without assuming the functions of a Court of appeal, and the power to re-try a question which the Judge was competent to decide."

   [138](1874) LR 5 PC 417 at 442-443.

3. Willan was frequently cited in this Court before Hickman and in Hickman itself, Dixon J referred to some of those citations[139].  Hickman has been applied on a number of occasions in this Court[140].

4. In R v Murray; Ex parte Proctor[141] Dixon J elaborated upon what has come to be called "the Hickman doctrine".  His Honour said:

   "But the question must always remain whether in a given case the writ does properly lie. That depends in turn upon the authority which the law gives to the proceedings which it is sought to prohibit. If the law denies to the tribunal in question all authority over the proceedings so that they cannot result in a lawful and effective exercise of power, then the proper remedy is prohibition."

   [141](1949) 77 CLR 387 at 398. See also Project Blue Sky v Australian Broadcasting Authority (1998) 194 CLR 355 at 389-390 [92] per McHugh, Gummow, Kirby and Hayne JJ.

5. Later, his Honour added[142]:

   "It then becomes a question whether, upon the true interpretation of the legislative instrument as a whole, it does not sufficiently express an intention that what the Board does shall be considered an authorized exercise of its power and accordingly valid and effectual, notwithstanding that the Board has failed strictly to pursue the procedure the instrument indicates or prescribes and that the Board has in some respects gone outside or beyond the limits within which it was intended that the actual exercise of its authority should be confined."

   [142]R v Murray; Ex parte Proctor (1949) 77 CLR 387 at 399.

6. His Honour then referred to the distinction between directory and mandatory provisions, forms of nomenclature which were both useful and descriptive, but which have since been criticised in this Court[143].  He said that the distinction supplies an analogy which may help to explain the effect of the relevant regulations[144]:

   "For construed in the traditional manner it must be taken to mean that strict compliance with at least some of the provisions of Part III [of the relevant regulations] is not an indispensable condition to the jurisdiction of the Board and to its authority to make a valid and binding award order or determination."

   [144]R v Murray; Ex parte Proctor (1949) 77 CLR 387 at 399.

7. Later, his Honour[145] stated the question to be whether the provision (with respect to the making of the relevant determination) is imperatively expressed, or may, on the contrary, yield to the general policy or intention indicated by the provision as to finality.

   [145]R v Murray; Ex parte Proctor (1949) 77 CLR 387 at 400.

8. The plaintiff argued in this case that the long line of authority to which I have referred, and in particular, the Hickman doctrine states no more than a mere rule of interpretation and has little or nothing to say about the denial of access to the remedies referred to in s 75(v) of the Constitution. I think that this is an understatement. Dixon J in Hickman and Proctor, as well as stating a rule of construction, embraces two important concepts. The first is that there is a distinction to be made between the exercise of an Executive power and a Judicial power. A court's scrutiny of the former should be undertaken with an understanding that officials and courts operate in different ways: they have different objects to achieve, and that the Constitution by the careful separation in it of the sections relating to Executive power from those concerning the Judicial power which reflect the underlying principle of the separation of powers is expressly indicative of this. The second concept is that because of the nature of Executive power and the way it has to be exercised, perfection will be unachievable, errors will inevitably be made, not all of which it will be the business of courts to correct, even if sufficient judicial resources were available to do so: hence the use in Proctor of "indispensable [requirements]" of the exercise of a power and of "manifest error" in Willan[146] and other cases. It is very likely that fraud or bribery also would be amenable to correction under s 75(v), being squarely within the Hickman doctrine as conduct falling short of being a bona fide attempt to exercise the relevant power. It may be, for example, that to attract the remedies found in s 75(v) of the Constitution when jurisdictional error is alleged, no less than a grave, or serious breach of the rules of natural justice will suffice, a matter which it is unnecessary to decide at this stage of these proceedings. In my opinion, these matters, the unqualified amplitude of the immigration power in s 51(xxvii) and perhaps also the external affairs power in s 51(xxix), and the careful selectivity by the founders of the remedies which would be available under the Constitution in s 75(v), relevantly require a strict, and perhaps less ambulatory or non-ambulatory reading of s 75(v), and a different approach to its meaning and application from the law which has developed in relation to the prerogative writs generally, and in which s 75(v) is not engaged. Indeed, in my opinion, these matters, the language and structure of the Constitution and the other matters to which I have referred give a particular relevance and vitality to the Hickman doctrine in Constitutional law.  The doctrine does not however provide any basis for a departure from the fundamental rule of statutory construction that a provision in an enactment or instrument is to be construed in context having regard to the statute or instrument as a whole.

   [146](1874) LR 5 PC 417 at 442.

9. In my opinion therefore, mandamus, prohibition and an injunction may go to cure manifest error of jurisdiction whether, in a relevant sense, by a failure to exercise it, or by a clear excess of it and not otherwise, notwithstanding the apparently absolute language of s 474 of the Migration Act.  Another way of expressing the rule is in terms of the Privy Council's advice in Willan, that the remedies will only lie if there has been a departure from an essential or imperative requirement on the part of the relevant officer or tribunal, or a material failure to comply with what might once have conventionally been described as a mandatory provision.  Both of these approaches have much in common with the approach of Mason ACJ and Brennan J in R v Coldham; Ex parte Australian Workers' Union[147] in which their Honours said that the privative provision "[could not] affect the operation of a provision which impose[d] inviolable limitations or restraints upon the jurisdiction or powers" (emphasis added), thereby recognizing that there might be degrees of limitation upon power, some violable and therefore legally tolerable, and some more serious and therefore inviolable and legally intolerable.

   [147](1983) 153 CLR 415 at 419. Dixon J had earlier, in R v Metal Trades Employers' Association; Ex parte Amalgamated Engineering Union, Australian Section (1951) 82 CLR 208 at 248 referred to "inviolable limitations or restraints [by enactments]".

10. Whether a decision made by an official or an administrative body is not within power or jurisdiction, and whether it is therefore invalid and ineffective, will only usually not be established unless and until a court of appropriate jurisdiction holds that to be so.  At that point, to adopt the language of McHugh J in Re Wakim; Ex parte McNally[148] the decision can be seen to "have no constitutional effect. For constitutional purposes [it is] a nullity." Whether however relief under s 75(v) will be granted may involve discretionary considerations as well as proof that an error of jurisdiction of a sufficient degree of gravity has been made[149].  The "decision" may not therefore necessarily turn out to be ineffective.

    [148](1999) 198 CLR 511 at 565 [79].

    [149]cf the suggestion to this effect by Gummow J in Minister for Immigration and Multicultural Affairs v Eshetu (1999) 197 CLR 611 at 657 [146].

11. I earlier noted the defendant's argument that s 474 of the Act enlarged the decision-making power of any Commonwealth officer making a decision of the kind to which the section applied, and that in that sense the jurisdiction of the officer or the tribunal was enlarged. To the extent that the submission would have it that those acting under the relevant provisions had a jurisdiction to exceed their jurisdiction, it must be rejected. Merely to state the unqualified proposition is to expose its frailty. It would also be a very unusual and indirect means of expanding a jurisdiction which, if the legislature had wanted those acting under the Migration Act to have, and it could constitutionally confer, it could have sought to confer directly in express terms.  The submission if correct, could also produce the constitutionally unacceptable consequence that a tribunal such as the one established under the Migration Act could conclusively determine its own jurisdiction.

12. It follows from what I have said that s 474 of the Act is not wholly invalid. It does not however provide a shield against the discretionary remedies of prohibition, mandamus and injunction available in this Court pursuant to s 75(v) of the Constitution in respect of errors of the kind that I have discussed.

    Is s 486A of the Act invalid?

13. Whether however the plaintiff can pursue his case in which he alleges jurisdictional error of a kind arguably entitling him to the constitutional remedies also depends upon the validity or otherwise of s 486A of the Act.

14. As I have observed, s 486A does not of itself, on its face, appear to seek to extinguish the right conferred by s 75(v) of the Constitution of any person to challenge in this Court a "privative clause decision". Nonetheless the questions remain: whether, notwithstanding its appearance, the section does in fact so substantially interfere with or limit access to the constitutional remedies for which s 75(v) provides, that it goes beyond regulation and renders them either nugatory or of virtually no utility; and, whether, in any event, the legislature may regulate (assuming the section to be regulatory only in effect) access to this Court under s 75(v).

15. In argument, the plaintiff asked the Court to infer a negative implication of absence of power of regulation with respect to the remedies under s 75(v) by reason of the express reference in s 73, and the absence of any reference in s 75, to regulation. This is an argument by no means lightly to be dismissed. However, as I have pointed out, s 73 itself was not literally construed in Smith Kline & French Laboratories[150] and what on its face appears to be a prohibition was treated there as in the nature of a mere regulation[151].

    [150](1991) 173 CLR 194.

    [151]See, for example, Judiciary Act 1903 (Cth), s 35(2).

16. The defendant relies on Parisienne Basket Shoes Pty Ltd v Whyte[152] in which Starke J said:

    "Prima facie, procedural statutes do not touch jurisdiction.  The Factories and Shops Act 1928 merely prescribes that a party shall lay his information within a prescribed period, but that touches his right to proceed and not the jurisdiction or capacity of the tribunal to adjudicate."

    [152](1938) 59 CLR 369 at 385.

17. In the same case Dixon J, with whom Evatt and McTiernan JJ agreed said[153]:

    "The limitation of time for laying an information is not a limitation upon the jurisdiction of the court or tribunal before whom the charge comes for hearing.  The time bar, like any other statutory limitation, makes the proceedings no longer maintainable, but it is not a restriction upon the power of the court to hear and determine them. It is not true that because an information is in fact laid out of time, the Court of Petty Sessions is powerless to deal with it.  Whether or not an information was laid too late is a question committed to their decision; it is not a matter of jurisdiction.  In courts possessing the power, by judicial writ, to restrain inferior tribunals from an excess of jurisdiction, there has ever been a tendency to draw within the scope of the remedy provided by the writ complaints that the inferior court has proceeded with some gross disregard of the forms of law or the principles of justice.  But this tendency has been checked again and again, and the clear distinction must be maintained between want of jurisdiction and the manner of its exercise."

    [153](1938) 59 CLR 369 at 388-389.

18. Citing Bell v Stewart[154], the defendant further submits that the High Court Rules, including those relating to time limits do not "limit" the right of appeal provided by s 73 of the Constitution; they "merely regulate the procedure by which the appeal is brought"; their presence and absence of challenge to them suggests that time limits of various kinds upon any proceedings in this Court are constitutionally acceptable.

    [154](1920) 28 CLR 419 at 424 per Knox CJ, Gavan Duffy and Starke JJ.

19. The thrust of the defendant's primary submission is that unless the regulation has the effect of prohibiting or extinguishing the right it will be valid.

20. The defendant seeks to uphold the section on yet other bases. One of these is that the section is within the constitutional power with respect to one or more of the naturalization and aliens power, the immigration power and the external affairs power. The answer to this last may readily be given, that all of these are subject to the Constitution which confers a power which cannot be extinguished, to grant the remedies to which s 75(v) refers.

21. As an additional argument, the defendant contends that s 486A is a valid law under s 51(xxxix) being a law with respect to a matter incidental to the execution of any power vested by the Constitution in the federal judicature: that the Parliament has already lawfully delegated legislative power to the High Court to make rules and that that power has been used since 1963. Order 55 r 30, which imposes a time limit of two months for an application for a writ of mandamus was given as an example of the exercise of this delegated power.

22. I accept that the Parliament may, consistently, in my opinion, with the approach of the Court to regulation and prohibition in Smith Kline & French Laboratories[155] regulate the procedure by which proceedings for relief under s 75(v) may be sought and obtained. But the regulation must be truly that and not in substance a prohibition.

    [155](1991) 173 CLR 194.

23. I have formed the opinion that s 486A is therefore invalid to the extent that it purports to impose a time limit of 35 days within which to bring proceedings under s 75(v) in this Court. There are certain matters which cannot be ignored for the purposes of judicial notice. Those matters include that the persons seeking the remedies may be incapable of speaking English, and will often be living or detained in places remote from lawyers pursuant to, for example, ss 178, 189, 192, 250 or 253 of the Migration Act.

24. In those circumstances, to prescribe 35 days within which to bring properly constituted proceedings in this Court under s 75(v) of the Constitution, which can only as a practical matter be filed in one of the capital cities, effectively would be to deny applicants recourse to the remedies for which it provides, particularly when, as here, the section purports to deny power to the Court to extend the time that it might otherwise have under O 60 r 6 of the Rules. Section 486A, although not wholly invalid, can have no operation in relation to the constitutional remedies of mandamus, prohibition and injunction.

25. I do not doubt that there is a power to prescribe time limits binding on the High Court in relation to the remedies available under s 75 of the Constitution as part of the incidental power with respect to the federal judicature. But those time limits must be truly regulatory in nature and not such as to make any constitutional right of recourse virtually illusory as s 486A in my opinion does. A substantially longer period might perhaps lawfully be prescribed, or perhaps even 35 days accompanied by a power to extend time. Finality of litigation is in all circumstances desirable. The Commonwealth has just as much interest in knowing that rights and remedies against it may no longer be pursued as do other litigants. As I earlier observed, the Commonwealth and its Executive have many departments to administer and many priorities to assess and allocations to make. These need to be able to be done upon a reasonably settled basis of the numbers involved and other demands upon the treasury of the nation. It is consonant with the exercise of both Executive and Judicial power that a finite reasonable time be fixed for the supervision by the latter over relevant decisions made by the former. It should also be kept in mind that in any event, delay may provide a discretionary bar to the grant of relief under s 75(v).

1. I would answer the questions in the stated case as follows:

   1Is section 486A of the Migration Act 1958 (Cth) invalid in respect of an application by the Plaintiff to the High Court of Australia for relief under section 75(v) of the Constitution?

   Answer:

   Upon its proper construction s 486A can have no valid operation with respect to the plaintiff's entitlement (if he can make it out) to mandamus and prohibition under s 75(v) of the Constitution.

   2Is section 474 of the Migration Act 1958 (Cth) invalid in respect of an application by the Plaintiff to the High Court of Australia for relief under section 75(v) of the Constitution?

   Answer:

   Section 474 would be invalid if, on its proper construction, it attempted to oust the jurisdiction conferred on the High Court by s 75(v) of the Constitution. However, on its proper construction, it does not attempt to do so. Section 474 is valid but does not apply to proceedings for mandamus or prohibition that the plaintiff would initiate.

   3By whom should the costs of the proceeding in this Honourable Court be borne?

   Answer:

   The costs of the proceedings should be borne as to 25% by the plaintiff and 75% by the defendant.
