Quadrant Research Services Pty Ltd v Dessmann & Anor

Quadrant Research Services Pty Ltd (the applicant) sought to restrain the respondents, Dessmann and another, from continuing to use certain confidential information and trade secrets. The dispute concerned the alleged misuse of proprietary information relating to a computer program developed by the applicant, which the respondents had allegedly obtained during a period of employment with the applicant. The matter came before the High Court of Australia.

The High Court was required to determine whether the respondents had breached their contractual and equitable obligations of confidence by using or disclosing the applicant's confidential information and trade secrets. Specifically, the court considered the scope of implied terms in employment contracts regarding the protection of confidential information and the application of the equitable doctrine of confidence in the context of former employees. The court also had to assess whether the information in question constituted confidential information or trade secrets, and if so, whether its use by the respondents amounted to a breach.

The High Court affirmed that an employee's duty of good faith and fidelity, implied in an employment contract, extends to a duty not to misuse or disclose confidential information acquired during employment, even after the termination of employment. This duty is distinct from, but reinforced by, the equitable doctrine of confidence. The court emphasised that the protection afforded to confidential information and trade secrets is not absolute and depends on the nature of the information and the circumstances of its acquisition and use. The court found that the information in question was indeed confidential and that the respondents' actions constituted a breach of their obligations.

The High Court granted an injunction restraining the respondents from using or disclosing the confidential information and ordered them to deliver up any materials containing such information.
