Unilever PLC v Livingstone International Pty Ltd

Unilever PLC (Unilever) sought interlocutory relief against Livingstone International Pty Ltd (Livingstone) in the Federal Court of Australia. The dispute concerned allegations of misleading and deceptive conduct and passing off in relation to the marketing and sale of laundry detergent products. Unilever contended that Livingstone's use of packaging and branding for its "Omo" laundry detergent was likely to deceive consumers into believing that the product was manufactured or endorsed by Unilever, which is the owner of the well-known "Omo" brand.

The primary legal issues before the court were whether Livingstone's conduct constituted misleading or deceptive conduct in contravention of the *Trade Practices Act 1974* (Cth) (now the *Competition and Consumer Act 2010* (Cth)), and whether it amounted to passing off at common law. Specifically, the court had to determine if there was a real likelihood of deception or confusion among consumers regarding the origin or affiliation of Livingstone's "Omo" product.

In reaching its decision, the court considered the visual similarities between the packaging of Unilever's "Omo" product and Livingstone's "Omo" product, including the use of the "Omo" name, colour schemes, and font styles. His Honour Justice Forno applied the established principles of misleading and deceptive conduct, focusing on the likely effect on the ordinary, reasonable consumer. The court also considered the common law principles of passing off, which require proof of goodwill, misrepresentation, and damage. The court found that there was a sufficient likelihood of deception and confusion to warrant interlocutory relief.

Consequently, the court granted an interlocutory injunction restraining Livingstone from marketing or selling its "Omo" laundry detergent in the manner complained of, pending the final determination of the proceedings.
