Bruce v Commonwealth Trade Marks Label Association

In this matter before the Full Court of the High Court of Australia, the plaintiffs, W. Bruce and D. R. Davies, sought to restrain the registration of a trade mark by the defendant, the Commonwealth Trade Marks Label Association, and Stephen Barker. The plaintiffs alleged that the proposed registration would injure their business as printers and stationers and contended that Part VII of the *Trade Marks Act 1905* (Cth) was beyond the legislative power of the Commonwealth Parliament. The Registrar of Trade Marks, also a defendant, informed the court that the application for registration had been withdrawn after the action was commenced.

The legal issues before the Full Court were whether it had the power to entertain a question of law concerning the constitutional validity of a Commonwealth statute when the substantive relief sought by the plaintiffs was no longer available due to the withdrawal of the trade mark application, and whether a declaratory order could be made in such circumstances. The plaintiffs argued that under Order III, rule 1 of the *Rules of the High Court 1903*, a declaratory order could be made even if no substantive relief could be granted.

The Full Court reasoned that it would not entertain abstract questions of law or give opinions on the validity of legislation where such opinions could not be followed by effective orders. The Court held that it was limited to determining rights that were actually controverted and that it was not empowered to decide moot questions or abstract propositions that could not affect the result of the case before it. Citing authorities, the Court emphasised that it would not give speculative opinions on hypothetical questions of law, but only answer questions arising in concrete cases involving private rights.

Consequently, the Full Court ordered that the case be struck out of the list, as the withdrawal of the trade mark application rendered the question of the Parliament's power to enact Part VII of the *Trade Marks Act 1905* a hypothetical one, and no effective relief could be granted to the plaintiffs.
