Wilson v Interhealth Energies Pty Limited

The District Court of New South Wales was asked to consider a dispute between Wilson and Interhealth Energies Pty Limited, wherein Wilson sought to enforce a promise made by Interhealth relating to a business sale. The case hinged on whether promissory estoppel, an equitable doctrine, could be applied in the District Court, which was typically seen as a court of law. The primary issue before the court was whether promissory estoppel is an equitable defence that falls within the jurisdiction of the District Court.

The court examined the statutory framework provided by the Law Reform (Law and Equity) Act 1972, specifically section 6, which delineates the equitable defences available to defendants in the District Court. The court found that promissory estoppel was not listed among the equitable defences that the District Court could entertain. As a result, the court held that promissory estoppel was not available to Interhealth as a defence in the District Court. The court's decision was based on a strict interpretation of the statutory language, which did not include promissory estoppel as an equitable defence within the court's jurisdiction.

As a consequence of the court's reasoning, Wilson's claim could not be supported by the doctrine of promissory estoppel in the District Court. The court dismissed Wilson's claim, finding that it did not have the authority to apply promissory estoppel as a defence. This decision underscored the importance of jurisdictional boundaries in relation to equitable doctrines and the specific statutory provisions that define them. The court's final orders were that Wilson's claim against Interhealth was dismissed without any orders for costs.
