Attorney-General (Vic) v Andrews

The Attorney-General of Victoria appealed to the High Court of Australia against a decision of the Federal Court concerning the interaction between Commonwealth and Victorian workers' compensation legislation. The dispute arose when Optus Administration Pty Ltd was granted a licence under the *Safety, Rehabilitation and Compensation Act 1988* (Cth), which subjected Optus to the federal scheme. The Attorney-General argued that the Victorian *Accident Compensation Act 1985* and the *Accident Compensation (WorkCover Insurance) Act 1993* were invalid to the extent that they were altered, impaired, or detracted from the operation of the federal Act.

The High Court was required to determine two principal legal issues. Firstly, whether the Victorian legislation was invalid due to inconsistency with the Commonwealth Act, specifically concerning the impact of the federal licence on Optus's obligations under Victorian law. Secondly, the Court had to consider whether certain provisions of the Commonwealth Act were invalid as laws with respect to "State insurance" within the meaning of s 51(xiv) of the Constitution, and conversely, whether the Victorian scheme constituted "State insurance" that the Commonwealth Act could not legislate upon.

The Court reasoned that the question of inconsistency under s 109 of the Constitution depended on the substance and operation of the legislation. Drawing on established principles, particularly from *Bourke v State Bank of New South Wales* and *Fairfax v Federal Commissioner of Taxation*, the Court affirmed that the characterisation of legislation is determined by the rights, duties, powers, and privileges it changes, regulates, or abolishes. The Court rejected the submission that the Commonwealth Act indirectly circumvented the exclusion of "State insurance" in s 51(xiv) of the Constitution. The Court found that the licensing provisions of the Commonwealth Act, in their true substance, were not laws with respect to insurance in a way that would invalidate them by reason of their incidental effect on State insurance obligations.

The appeal was dismissed, and the appellant was ordered to pay the costs of the respondents.
