Australian Super Developments Pty Ltd v Marriner (No 2)

In the Federal Court, Australian Super Developments Pty Ltd brought an action against Marriner, seeking an injunction to restrain the defendant from proceeding with the sale of certain land. Marriner counterclaimed, alleging misleading and deceptive conduct by the plaintiff and seeking damages, an account of profits, and an injunction. The case focused on whether Marriner's claims were substantiated by evidence and whether the counterclaimants suffered a loss as a result of the plaintiff's conduct.

The court was required to determine the nature and effect of any representations made by the plaintiff that could be considered misleading or deceptive. Additionally, the court had to assess whether Marriner relied on these representations and if such reliance led to a loss. The court also needed to consider the applicability of estoppel in the context of the counterclaimants' claims.

The court found that the plaintiff's representations were not misleading or deceptive as they were made in good faith and were not intended to create a false impression. The court held that Marriner did not rely on any representations made by the plaintiff and, therefore, did not suffer any loss as a result. The court also dismissed the counterclaimants' estoppel argument, concluding that there was no basis for the application of estoppel in this case. Consequently, the counterclaim was dismissed, and the plaintiff was granted an injunction against the defendant.

The court ordered that the defendant refrain from proceeding with the sale of the land in question. Additionally, the court ruled that the plaintiff was entitled to recover costs associated with the proceedings from the counterclaimants. The decision underscored the importance of establishing reliance and loss in claims of misleading and deceptive conduct, as well as the stringent requirements for the application of estoppel in similar disputes.
