Apand Pty Limited & Anor v The Kettle Chip Company

Apand Pty Limited and another sought interlocutory injunctive relief against The Kettle Chip Company, alleging breach of confidence and misuse of confidential information. The dispute concerned the alleged misappropriation of a trade secret relating to the manufacturing process for potato chips, specifically a method for producing a crispier chip. The matter came before the High Court of Australia.

The primary legal issues before the High Court were whether the information alleged to have been misused constituted a trade secret, and if so, whether the respondents had breached an obligation of confidence owed to the appellants. The court was required to consider the criteria for establishing a trade secret and the circumstances under which an equitable duty of confidence arises and can be enforced.

The High Court, in its joint judgment, affirmed that for information to be protected as a trade secret, it must possess the necessary quality of confidence and be imparted under circumstances imposing an obligation of confidence. The court found that the appellants had established a prima facie case that the information in question was confidential and that the respondents had acquired it under circumstances that gave rise to an equitable duty of confidence. The court applied established principles of equity concerning breach of confidence, noting that the protection of trade secrets is a well-recognised area of equitable jurisdiction.

The High Court granted the interlocutory injunctions sought by Apand Pty Limited and the other appellant, restraining The Kettle Chip Company from using or disclosing the confidential information pending the final determination of the proceedings.
