Karen Walker Limited v Premonition Designs Pty Ltd and Mamta Group Pty Ltd

Karen Walker Limited (the applicant) sought an interlocutory injunction against Premonition Designs Pty Ltd and Mamta Group Pty Ltd (the respondents) to restrain them from infringing its registered trade mark "KAREN WALKER" and passing off their goods as those of the applicant. The application was heard in the Federal Court of Australia.

The primary legal issues before the Court were whether the respondents' use of the mark "KAREN WALKER" on their clothing and accessories constituted trade mark infringement under the *Trade Marks Act 1995* (Cth), and whether such use amounted to passing off at common law. Specifically, the Court had to consider the likelihood of confusion among consumers as to the origin of the goods.

Her Honour Justice Robertson found that there was a serious question to be tried regarding both trade mark infringement and passing off. The Court applied the principles of interlocutory injunctions, requiring the applicant to demonstrate a prima facie case or a strong arguable case, and that the balance of convenience favoured granting the injunction. The Court considered the distinctiveness of the applicant's mark, its established reputation, and the similarity between the marks and the goods. The Court concluded that the respondents' use of the mark was likely to deceive or cause confusion, and that the potential damage to the applicant's reputation and goodwill outweighed any prejudice to the respondents.

The Court ordered that the respondents be restrained from using the mark "KAREN WALKER" in relation to clothing and accessories, pending the final determination of the proceedings.
