Wynton Stone Australia Pty Ltd (In Liquidation) v MWH Australia Pty Ltd (Formerly Montgomery Watson Australia Pty Ltd) [2011] HCATrans 61

The High Court of Australia, constituted by Heydon and Crennan JJ, considered an application for special leave to appeal in the matter of Wynton Stone Australia Pty Ltd (In Liquidation) and MWH Australia Pty Ltd (Formerly Montgomery Watson Australia Pty Ltd). The dispute concerned the interpretation and application of certain provisions within a construction contract, specifically relating to the calculation of a final account and the entitlement to certain payments.

The primary legal issue before the High Court was whether the Court of Appeal of New South Wales had erred in its construction of the contract, particularly concerning the interplay between clauses dealing with the final account and the consequences of a contractor's failure to comply with specific contractual timeframes. The applicant sought to challenge the Court of Appeal's finding that the respondent was entitled to payment despite alleged breaches of these timeframes.

Their Honours granted special leave to appeal, indicating that there were arguable grounds for review concerning the contractual interpretation. The reasoning, as foreshadowed by the grant of leave, likely focused on whether the Court of Appeal had correctly applied established principles of contractual construction, particularly in circumstances where strict adherence to procedural requirements might otherwise have led to a forfeiture of rights. The High Court would have considered whether the Court of Appeal's interpretation gave undue weight to one set of provisions over another, or whether it had failed to give proper effect to the clear language of the contract.

The High Court ultimately granted special leave to appeal and ordered that the appeal be heard.
