Narui Gold Coast Pty Ltd v Charles Harrison Pty Ltd

Narui Gold Coast Pty Ltd brought proceedings against Charles Harrison Pty Ltd seeking to avoid a contract on the basis of common mistake. The defendant raised a defence of estoppel, claiming that the plaintiff had acted inconsistently with its assertion of a mistake in the contract. The dispute came before the Supreme Court of Queensland. The primary legal issue before the court was whether the plaintiff was entitled to avoid the contract due to a common mistake and whether the defendant's estoppel defence was properly pleaded. The court had to consider whether the plaintiff's claim for relief was consistent with the equitable maxim that a person who seeks equity must come with clean hands and whether the defendant's estoppel defence was sufficiently pleaded to warrant the grant of leave to re-plead.

The court held that the plaintiff's claim to avoid the contract was not precluded by the maxim that equity requires clean hands because there was an immediate and necessary relation to the equity sought. The court found that the plaintiff's claim for relief was not inconsistent with the maxim, as the relief sought was directly related to the equity of the situation. Regarding the defendant's estoppel defence, the court found that the defence was not properly pleaded as it did not provide sufficient particulars of the facts upon which the estoppel arose. The court considered whether it was appropriate to grant leave to re-plead, taking into account the principles of Supreme Court procedure and the need for pleadings to state with particularity the facts showing why the estoppel arises. Ultimately, the court found that it was not appropriate to grant leave to re-plead as the defendant had not demonstrated sufficient grounds for an amendment to the pleadings.

The court dismissed the defendant's estoppel defence and ordered that the defendant pay the plaintiff's costs of the proceedings. The court did not make any orders regarding the plaintiff's claim to avoid the contract on the basis of common mistake, as that issue was not fully argued before the court. The court held that the defendant's estoppel defence was not properly pleaded and that it was not appropriate to grant leave to re-plead. The court emphasised the importance of pleadings stating with particularity the facts upon which a defence is based and the need for an immediate and necessary relation to the equity sought in order for a claim to be consistent with the maxim that equity requires clean hands.
