McDonald v Commissioner of Business Franchises

The Commissioner of Business Franchises sought to recover unpaid franchise fees from McDonald. McDonald argued that the Commissioner was estopped from recovering these fees due to representations made by the Commissioner's officers. The High Court of Australia was tasked with determining whether the Commissioner was bound by these representations.

The central legal issue before the High Court was whether the doctrine of estoppel could operate to prevent a statutory authority, such as the Commissioner of Business Franchises, from exercising its statutory power to recover unpaid franchise fees, where such a prevention would be contrary to the public interest. The court also considered the circumstances under which a public authority might be estopped by the conduct of its officers.

The High Court held that the Commissioner was not estopped from recovering the unpaid franchise fees. The majority reasoned that the Commissioner's statutory duty to collect fees was a public duty, and that allowing estoppel to prevent the recovery of these fees would be contrary to the public interest. The court affirmed the principle that estoppel will not generally be applied against a public authority where it would frustrate the performance of its statutory obligations or be contrary to the public interest. The court distinguished this case from situations where estoppel might apply to prevent a public authority from acting in a manner inconsistent with representations made, particularly where no public interest is adversely affected.

The High Court ordered that the Commissioner was entitled to recover the unpaid franchise fees.
