Air Caledonie International & Ors v The Commonwealth of Australia

Air Caledonie International and others, the plaintiffs, brought proceedings against the Commonwealth of Australia, the defendant, in the High Court of Australia. The plaintiffs alleged that section 34A, and specifically subsection (3), of the Migration Amendment Act 1987 (Cth) was invalid on the grounds that it exceeded the legislative power of the Commonwealth.

The central legal issue before the High Court was the constitutional validity of section 34A of the Migration Amendment Act 1987. This section imposed a prescribed fee for immigration clearance on passengers arriving in Australia on overseas flights, with certain exceptions for "prescribed passengers" as defined by regulations. The plaintiffs contended that this legislative provision was beyond the scope of the Commonwealth's constitutional authority.

The Court was required to consider the ambit of the Commonwealth's legislative powers, particularly in relation to immigration and the imposition of fees or taxes. The plaintiffs argued that the fee imposed by section 34A was not a valid exercise of any head of Commonwealth power. The defendant, the Commonwealth, would have contended that the provision was supported by an appropriate constitutional power, likely related to immigration or external affairs. The definition of "overseas flight" and the scope of "prescribed passenger" were also relevant to the interpretation and application of the impugned section.
