Act 1939-1943 and the regulations thereunder had ceased to be in force and were not continued in force by the National Security Act 1946. He claimed declara- tions accordingly, and also that the regulations were not authorized by the Constitution and were void and of no effect. The defendants demurred.
Held, by Latham C.J., Dixon and McTiernan JJ. pro (Rich, Starke and Williams JJ. contra), that the demurrer should be allowed and judgment given for the defendants.
Held, by Latham C.J., Dixon and McTiernan JJ. (Rich, Starke and Williams JJ. dissenting), that the regulations in Part III. of the National Security (Economic Organization) Regulations were valid when made: by virtue of S. 19 of the National Security Act 1939-1943 they continued in force notwithstanding the surrender of enemy nations; they were still valid as legislation under the defence power and they would come to an end on 31st December 1946 as regulations under the Act by reason of the provisions of S. 19 as inserted by S. 2 of the National Security Act 1946.
Held, by Rich, Starke and Williams JJ., that the "absolute discretion" conferred upon the Treasurer by reg. 9 (2) of the National Security (Economic Organization) Regulations was not authorized by the defence power.
Held, by Latham C.J., Starke and McTiernan JJ., that His Majesty did not cease to be engaged in war" within the meaning of S. 19 of the National Security Act 1939-1943 upon the cessation of active hostilities.
Held, by Latham C.J., Dixon and McTiernan JJ., that the defence power includes not only a power to prepare for war and to prosecute war, but also a power to wind-up after a war and to restore a condition of peace as gradually as the particular circumstances may require.
Held, by Rich J., that the scope of the defence power becomes very wide in time of war, and does not shrink to its normal peace-time dimensions immediately on cessation of hostilities, although (by Starke J.) the increasing change after the cessation of hostilities in the circumstances which called for war-time legislation affords less justification for the continuance of that legislation than when it was passed even if then valid.
Per Latham C.J. and McTiernan J.: (1) If it can reasonably be considered that there is a real connection between the subject matter of certain legislation and defence the Court should hold that the legislation is authorized by the power to make laws with respect to defence; and (2) The scope of possible legislation under the defence power varies from time to time in accordance with the circumstances of the time, and the mere fact that a state of war con- tinues does not in itself authorize the continuance of laws which may have been validly operative when made, but which cannot he regarded as having any relation to defence at a later time when their validity is challenged.
The application of S. 46 (b) of the Acts Interpretation Act 1901-1941 to the provisions of reg. 9 (2) of the National Security (Economic Oganization) Regula- tions, considered.
