Theodore v Mistford Pty Ltd & Ors

Theodore (the appellant) brought proceedings against Mistford Pty Ltd and others (the respondents) in the High Court of Australia concerning the enforceability of a guarantee. The dispute centred on whether the appellant was entitled to enforce a guarantee provided by the respondents in favour of a company, Theodore Pty Ltd (in liquidation), in circumstances where the company had been deregistered.

The primary legal issue before the High Court was whether the deregistration of the company, Theodore Pty Ltd, extinguished the debt owed to it, thereby rendering the guarantee unenforceable. The appellant argued that the debt survived the deregistration and that he, as a director and creditor of the company, had a sufficient interest to pursue the guarantee. The respondents contended that the deregistration of the company meant it no longer existed as a legal entity capable of owing a debt, and consequently, the guarantee, which was contingent on that debt, could not be enforced.

The High Court, in a joint judgment, held that the deregistration of a company does not extinguish its debts. Drawing on established principles of corporate law, their Honours explained that while deregistration terminates the company's existence as a legal entity, its assets and liabilities do not simply vanish. Instead, they vest in the Commonwealth for the benefit of creditors and other interested parties. The Court reasoned that the guarantee was a promise to answer for the debt of Theodore Pty Ltd, and the debt itself continued to exist despite the company's deregistration. Therefore, the appellant, as a creditor with a proprietary interest in the debt, had standing to enforce the guarantee.

The High Court allowed the appeal, setting aside the orders of the Full Federal Court and remitting the matter to the Federal Court of Australia for further determination.
