In the application by Soul Pattinson (Laboratories) Pty. Ltd. and others ("Soul Pattinson"), Soul Pattinson was the respondent in a proceeding commenced in the general division of the Federal Court of Australia by delivery of a statement of claim which alleged that the applicant Richardson-Merrell Pty. Ltd. ("Richardson-Merrell") had since 1970 manufactured for sale in Australia and sold in Australia a "skin care product under the name Oil of Ulan" got up in a particular manner. It was alleged that the product had become widely known to consumers and that Richardson-Merrell had acquired a substantial reputation in the product and that the get-up was distinctive of its product. It further alleged that Soul Pattinson (Laboratories) Pty. Limited had commenced to produce and other respondents to market, in Australia, a skin care product in cartons "got up so as to be misleadingly and deceptively similar" to Richardson-Merrell's product and that such conduct was "misleading or deceptive or likely to mislead or deceive". The relief sought in the proceedings was a declaration that Soul Pattinson had engaged in conduct constituting a contravention of ss. 52 and 53 of the Trade Practices Act, an injunction restraining Soul Pattinson from manufacturing, distributing etc. a skin care product, not manufactured under licence of Richardson-Merrell, which is so got up as to be substantially identical with or deceptively similar to the appearance of the get-up of Richardson-Merrell's skin care product, and from manufacturing, distributing etc. a product substantially identical with or deceptively similar to the appearance or the get-up of Richardson-Merrell's product in such a manner as to engage in conduct constituting a contravention of ss. 52 and 53, an order for delivery up by Soul Pattinson of all cartons, and advertising material etc. which is in the possession, power or control of Soul Pattinson and which is got up to be in appearance substantially identical with or deceptively similar to the appearance of the get-up of the skin care product manufactured and sold by Richardson-Merrell, an inquiry into loss and damage suffered by Richardson-Merrell by the conduct of Soul Pattinson in contravention of s. 52 or s. 53 and an order that Soul Pattinson pay Richardson-Merrell the amount of such loss and damage and finally an injunction restraining Soul Pattinson from manufacturing, distributing etc. or selling whether by use of the said cartons or otherwise any skin care product which is got up in such a way as to be calculated to lead to such product being believed to be or passed off or sold as being the skin care product of Richardson-Merrell. By notice of motion dated 7th April 1978 Richardson-Merrell sought an interlocutory injunction. The order nisi dated 17th April 1978 gave us grounds for the issue of a writ of prohibition that "the last named respondent [Richardson-Merrell] is a competitor of the first named prosecutor [Soul Pattinson] and not a person having standing to constitute proceedings for relief under s. 80 of the Trade Practices Act 1974 and that as a consequence the respondent Judges of the Federal Court of Australia and each and every one of them do not have jurisdiction to hear the said application". On a later date a further ground was added, namely, that the Trade Practices Act did not confer upon the Federal Court jurisdiction to hear a claim for damages in respect of an injury to reputation or otherwise to hear a claim for the order sought and a further ground that in so far as the proceedings claimed an injunction Richardson-Merrell had no standing to sue for such relief under the Trade Practices Act and that the proceedings were proceedings for passing off and that accordingly the Federal Court had no jurisdiction to hear the application.
