CaseChat Overview and Summary
The High Court of Australia considered the validity of Division 104 of the *Criminal Code* (Cth), which empowers federal courts to make interim control orders imposing obligations, prohibitions, and restrictions on individuals to protect the public from terrorist acts. The plaintiff, who was subject to such an order made by the first defendant, Mowbray FM, at the application of the second defendant, an officer of the Australian Federal Police, challenged the validity of this order.
The central legal issues before the Court were whether Division 104 of the *Criminal Code* was constitutionally valid. This involved determining whether the Division conferred non-judicial power on Chapter III courts, whether it authorised the exercise of judicial power in a manner contrary to Chapter III, and whether it was supported by a valid head of legislative power under the Commonwealth Constitution. Specific sub-issues included whether the defence power extended to non-state actors, whether the external affairs power was engaged, and whether the provisions conferred non-justiciable matters or impermissibly directed courts to consider future conduct.
The majority of the Court found that Subdivision B of Division 104, which deals with the making of interim control orders, was valid. The Court reasoned that the power conferred by Division 104, while involving considerations of future risk, was sufficiently defined by legal criteria and did not amount to an impermissible delegation of non-judicial power or a compulsion to exercise judicial power in a manner contrary to Chapter III. The Court also found that the Division was supported by the defence power, which it held extends to protecting the Commonwealth from threats posed by non-state actors, and by the external affairs power. The Court concluded that the criteria for making an interim control order, such as whether it was "reasonably necessary" for the purpose of protecting the public from a terrorist act, provided sufficient legal guidance.
The Court answered the questions posed in the special case. It held that Subdivision B of Division 104 was valid, and it was inappropriate to answer the broader questions regarding the invalidity of the entire Division. The plaintiff was ordered to pay the costs of the Commonwealth.
