Slee v Warke

The parties to this matter were Slee and Warke. The dispute concerned a contract for the sale of land, and the proceedings were heard by the High Court of Australia.

The High Court was required to determine whether the contract for the sale of land should be rectified on the grounds of mutual mistake, or alternatively, whether rectification should be ordered based on unilateral mistake. The court also considered whether specific performance or damages should be awarded in relation to the contract.

The court's reasoning focused on the principles governing rectification for mistake. It was held that rectification for mutual mistake requires proof that both parties were under a common misapprehension as to the terms of the agreement, and that the written instrument does not accurately reflect their true intentions. The court also examined the circumstances under which rectification might be available for unilateral mistake, particularly where one party is aware of the other's mistake and seeks to take advantage of it. The court applied established equitable principles relating to the correction of written instruments to reflect the true agreement of the parties.

The court ultimately ordered that the contract be rectified to reflect the true agreement of the parties.
