Taco Bell Corporation v Taco Bill Mexican Restaurants (Australia) Pty Ltd

This decision concerns a trade mark application by Taco Bill Mexican Restaurants (Australia) Pty Ltd for the mark "TACO BILL" across various goods and services, including food, drink, and hospitality. Taco Bell Corporation filed an opposition to this application, raising several grounds, including that the mark is not capable of distinguishing the applicant's goods and services, that its use would be contrary to law, and that the applicant is not the owner of the mark. Taco Bell Corporation subsequently applied to the Registrar of Trade Marks for a summons requiring Taco Bill Mexican Restaurants to produce documents relating to its dealings with a restaurant in Newcastle operating under the name "Taco Bill's Restaurant."

The primary legal issue before the Registrar was whether the documents sought by Taco Bell Corporation were arguably relevant to the grounds of opposition, particularly those concerning the distinctiveness of the "TACO BILL" mark under section 41 of the *Trade Marks Act 1995*. Taco Bell Corporation contended that evidence of another entity using the name "Taco Bill" would demonstrate that the mark is not capable of distinguishing the applicant's goods and services, as it suggests a common use of the term. The Registrar was required to determine the appropriate test for relevance in such discovery proceedings and whether the requested documents met that threshold.

The Registrar applied the principle that a party seeking production of documents need not prove substantive relevance but must show that the material sought is arguably relevant to the issues in dispute. While initially unconvinced that dealings with a separate restaurant in Newcastle were relevant to the inherent distinctiveness of the "TACO BILL" mark, the Registrar reconsidered after Taco Bell Corporation argued, by reference to *Melhero Pty Ltd v Club X*, that evidence of multiple users of a name could bear directly on its capacity to distinguish. The Registrar accepted that this interpretation was arguable, finding that documents showing multiple entities using the name "Taco Bill" might arguably be relevant to the section 41 grounds of opposition.

Consequently, the Registrar ordered the issuance of a notice requiring both Taco Bill Mexican Restaurants (Australia) Pty Ltd and the proprietors of the Newcastle restaurant to produce all documents relating to their dealings from 1 January 1985 to the date of the notice. The Registrar outlined the procedural steps for the production of these documents, including provisions for objections and claims of reasonable excuse for non-production.
