Minister for Home Affairs v Benbrika

The High Court of Australia considered the constitutional validity of Division 105A of the Criminal Code (Cth), which allows for the making of continuing detention orders against individuals convicted of terrorist offences. The Minister for Home Affairs sought such an order against Mr Benbrika, leading to a challenge to the constitutional basis of the Division. The central dispute concerned whether the power to make these orders, conferred on State Supreme Courts, infringed Chapter III of the Constitution by vesting non-judicial power in courts that exercise federal jurisdiction.

The legal issues before the Court were whether Division 105A, or any part of it, was invalid because the power to make a continuing detention order under section 105A.7 of the Code was not within the judicial power of the Commonwealth and had been conferred on State Supreme Courts contrary to Chapter III of the Constitution. This required the Court to consider whether the scheme for preventative detention of terrorist offenders could fall within an exception to the principle that involuntary detention is penal or punitive and thus an incident of the judicial function of adjudging and punishing criminal guilt. The Court also had to determine if the Division was directed towards the safety and protection of the community from the risk of harm posed by terrorism.

The Court reasoned that the power to make a continuing detention order under Division 105A was not invalid. It held that such orders were not punitive in character but rather served a protective purpose, aimed at preventing future harm to the community by individuals posing an unacceptable risk of engaging in terrorist acts. This protective purpose distinguished the orders from the penal consequences of adjudging and punishing criminal guilt, thereby allowing them to be made by courts exercising federal jurisdiction without violating Chapter III of the Constitution. The Court applied the exception to the principle established in *Chu Kheng Lim v Minister for Immigration* (1992) 176 CLR 1, finding that the involuntary detention authorised by Division 105A was for a non-punitive, protective purpose.

The Court answered the question reserved for its consideration in the negative, holding that no part of Division 105A of the Criminal Code was invalid on the grounds raised. The respondent, Mr Benbrika, was ordered to pay the applicant's costs.
