YBFZ v Minister for Immigration, Citizenship and Multicultural Affairs

In *YBFZ v Minister for Immigration, Citizenship and Multicultural Affairs*, the High Court of Australia considered the constitutional validity of certain conditions imposed on a Bridging R (Class WR) visa. The plaintiff, who had been granted such a visa subject to a monitoring condition requiring electronic tracking and a curfew condition restricting movement during specific hours, was subsequently arrested and charged with offences for allegedly failing to comply with these conditions. The core of the dispute concerned whether these conditions, and their associated penalties, infringed Chapter III of the Australian Constitution, which delineates the separation of judicial power.

The central legal issue before the Full Court was whether clauses 070.612A(1)(a) and (d) of Schedule 2 to the *Migration Regulations 1994* (Cth), which respectively mandated electronic monitoring and a nightly curfew as conditions for the visa, were invalid. This invalidity was alleged to arise from an infringement of Chapter III of the Constitution, either independently or in conjunction with each other, particularly in light of the severe penalties for non-compliance, including a mandatory minimum sentence of one year's imprisonment.

The Court reasoned that the monitoring and curfew conditions, when viewed in conjunction with the significant penalties for their breach, were not reasonably capable of being seen as serving a legitimate and non-punitive purpose. Instead, the Court found that these conditions, by imposing substantial restrictions on individual liberty and bodily integrity and carrying punitive consequences, encroached upon the exclusive judicial power of the Commonwealth. The Court applied principles derived from the "Lim principle," which concerns the non-delegation of judicial power and the prohibition against the executive imposing punishment. Consequently, the Court declared that both clauses 070.612A(1)(a) and (d) of Schedule 2 to the *Migration Regulations 1994* (Cth) were invalid. The defendant was ordered to pay the costs of the special case.
