Xipolitas v Auburn United Pty Ltd

In *Xipolitas v Auburn United Pty Ltd* [1995] NSWCA 528, the New South Wales Court of Appeal considered a dispute concerning a contract for the sale of land. The appellant, Xipolitas, was the vendor and the respondent, Auburn United Pty Ltd, was the purchaser. The core of the disagreement revolved around whether the purchaser had validly exercised an option to purchase the land.

The primary legal issue before the Court of Appeal was whether the notice of exercise of the option to purchase the land was effective. This involved determining whether the notice complied with the terms of the option agreement and, if not, whether the vendor had waived any non-compliance or was estopped from relying on it. The Court also had to consider the implications of the purchaser's conduct in relation to the property after the purported exercise of the option.

The Court of Appeal found that the notice of exercise of the option was defective because it did not strictly comply with the requirements stipulated in the option agreement. However, the Court further held that the vendor, through its conduct and representations, had waived its right to insist on strict compliance with the terms of the notice. The principles of waiver and estoppel were applied, establishing that the vendor's actions led the purchaser to believe that the notice was sufficient and that the option had been validly exercised. Consequently, the vendor was precluded from later asserting the invalidity of the notice.

The Court of Appeal dismissed the appeal, upholding the primary judge's decision that the option had been validly exercised and that the contract for sale was therefore binding.
