Hawkesbury City Council v Grewlan Investments Pty Ltd

The dispute in Hawkesbury City Council v Grewlan Investments Pty Ltd involved the Hawkesbury City Council and Grewlan Investments Pty Ltd, with the matter being heard in the Supreme Court of New South Wales. The primary issue was whether Grewlan Investments Pty Ltd was estopped from claiming compensation for land that was dedicated to the Council, based on representations made by Mr DeMarco, a representative of Grewlan. The Council sought to enforce a representation made by Mr DeMarco, that Grewlan would not claim compensation for the land dedicated to the Council if the parties entered into a deed for the construction of a road. Grewlan argued that the representation was not binding and that there was no mutual mistake necessitating rectification of the deed.

The court examined whether Mr DeMarco's conduct constituted a misleading or deceptive representation. The court rejected Grewlan's argument that the conduct was not misleading or deceptive, finding that the representation was clear and that Grewlan was estopped from claiming compensation. The court noted that Grewlan's objection to and deletion of a clause that would have precluded a compensation claim did not negate the representation made by Mr DeMarco. Furthermore, the court held that the representation was a statement of Grewlan's state of mind at the time, which bound Grewlan to its terms. The court also dismissed Grewlan's argument that the representation was not within trade or commerce and therefore not subject to statutory relief.

The court concluded that Grewlan was estopped from claiming compensation for the dedicated land. The representation made by Mr DeMarco was clear and unequivocal, and Grewlan was bound by it. The court found that rectification was not necessary as there was no mutual mistake, and Grewlan was not entitled to rely on the absence of a mutual mistake to avoid the estoppel. The court held that the estoppel was based on the representation made by Mr DeMarco and the Council's reliance on it. The court's decision was based on the principle that a party cannot be allowed to rely on a mistake if the other party is aware of the mistake and deliberately sets out to ensure that the mistaken party does not become aware of the mistake.
