Phillip Morris Inc & Phillip Morris Ltd v Adam P. Brown Male Fashions Pty Ltd

Phillip Morris Inc and Phillip Morris Ltd sought an interlocutory injunction against Adam P. Brown Male Fashions Pty Ltd in a legal dispute concerning trademark infringement and unfair competition. The case was heard by the High Court of Australia, which was asked to determine the legality of an application to vary an existing undertaking given to the Court in lieu of an injunction. The appellants argued that the trial judge had erred in granting the respondent's application to vary the undertaking, which they claimed was not permissible under the law.

The legal issues before the Court included whether the trial judge had the power to release a party from an undertaking given in lieu of an injunction due to a mistake or error, and if so, under what circumstances. The Court needed to consider the discretion available to a trial judge in such matters and whether the trial judge had exercised that discretion properly. The appellants contended that the trial judge had exceeded his jurisdiction by making an order that varied the terms of the original undertaking without sufficient justification.

The Court found that the trial judge had indeed exceeded his jurisdiction by varying the terms of the undertaking given to the Court. The undertaking in question was a substitute for an injunction and was considered a final order until set aside by the Court. The Court concluded that the trial judge did not have the power to alter the terms of such an undertaking without the Court's explicit consent. Furthermore, the Court held that the trial judge had not acted within his jurisdiction when he granted the respondent's application to vary the undertaking. As a result, the Court set aside the judgment and order appealed from, dismissed the respondent's motion, and allowed the appeal with costs.
