Castle Constructions Pty Limited v Sahab Holdings Pty Ltd and Anor

Castle Constructions Pty Limited (the appellant) appealed to the High Court of Australia against a decision of the Court of Appeal of the Supreme Court of New South Wales. The dispute concerned the interpretation of a clause within a contract for the sale of land, specifically whether the appellant had validly exercised an option to extend the settlement date. The respondent, Sahab Holdings Pty Ltd, argued that the appellant had failed to comply with the conditions precedent to exercising the option, rendering the extension invalid.

The High Court was required to determine whether the notice of exercise of the option to extend the settlement date was validly given in accordance with the terms of the contract. This involved considering the proper construction of clause 11.2 of the contract, which stipulated the conditions that had to be met before the option could be exercised, and whether those conditions had been satisfied by the appellant.

The Court reasoned that the plain language of clause 11.2 required the appellant to provide written notice of its intention to extend the settlement date and to pay a specified sum of money. The Court found that while the appellant had provided written notice, it had failed to pay the required sum concurrently with the notice. This failure meant that the conditions precedent to the valid exercise of the option had not been met. The Court applied the principle that where a contract specifies conditions precedent to the exercise of an option, those conditions must be strictly performed.

The High Court allowed the appeal, finding that the notice of exercise of the option was invalid. Consequently, the contract was terminated, and the appellant was not entitled to an extension of the settlement date.
