Schneider v Hoechst Schering Agrevo Pty Limited and Anor S55/2001

Schneider v Hoechst Schering Agrevo Pty Limited and Anor S55/2001 was a case heard by the High Court of Australia, with judgment delivered by Gleeson CJ and McHugh J. The dispute concerned an application by the plaintiff, Schneider, for an interlocutory injunction to restrain the defendants, Hoechst Schering Agrevo Pty Limited and another, from continuing to use or exploit certain confidential information and trade secrets. Schneider alleged that this information had been improperly obtained and was being used in breach of confidence.

The primary legal issue before the High Court was whether the plaintiff had established a sufficient likelihood of success on the merits to justify the grant of an interlocutory injunction. This involved considering whether the information in question was indeed confidential, whether it had been imparted in circumstances importing an obligation of confidence, and whether there had been an actual or threatened breach of that obligation. The court also had to assess the balance of convenience between the parties, considering the potential harm to each if the injunction was granted or refused.

In their joint judgment, Gleeson CJ and McHugh J applied the principles governing the grant of interlocutory injunctions, particularly the test established in *Australian Broadcasting Corporation v O'Neill*. This test requires the applicant to demonstrate that there is a "real question to be tried" and that the balance of convenience favours the grant of the injunction. The court found that the plaintiff had not discharged the onus of showing a sufficient likelihood of success to warrant the grant of the interlocutory relief sought, and that the balance of convenience did not favour the plaintiff. Consequently, the application for an interlocutory injunction was dismissed.
