SDCV v Director-General of Security

The appellant, SDCV, challenged an adverse security assessment made by the Director-General of Security, which led to the cancellation of his visa on character grounds. The appellant sought merits review of this assessment before the Administrative Appeals Tribunal (AAT). The Minister, citing national security concerns, issued certificates under s 39B(2)(a) of the Administrative Appeals Tribunal Act 1975 (Cth) (AAT Act), preventing the disclosure of certain information related to the security assessment to the appellant or his representatives. The AAT affirmed the security assessment. The appellant then appealed to the Federal Court of Australia.

The central legal issues before the High Court of Australia concerned the constitutional validity of s 46(2) of the AAT Act. Specifically, the appellant argued that this provision, which prohibited the disclosure of certificated matter to parties in an appeal to the Federal Court, was invalid. The grounds for this argument were that it denied a party a fair opportunity to respond to evidence that could determine their rights or interests, thereby infringing Chapter III of the Constitution, and that it required or authorised the Federal Court to act inconsistently with the essential character of a court or the nature of judicial power.

The High Court rejected the appellant's arguments. The Court reasoned that s 46(2) of the AAT Act, when considered alongside the forensic advantage conferred by s 46(1) (which allowed the Federal Court to consider the certificated matter), did not cause practical injustice. The Court held that Parliament was entitled to strike a balance between competing public interests, including national security and the rights of individuals, and that there was no constitutional imperative for such balancing to be conducted solely on a case-by-case basis by the courts. The Court noted that the appellant had a choice of remedial procedures, and the chosen procedure, while having limitations, was not practically unjust compared to the alternatives.

The appeal was dismissed with costs.
