Leighton Contractors Pty Ltd v South Australian Superannuation Fund Investment Trust

Leighton Contractors Pty Ltd (Leighton) and the South Australian Superannuation Fund Investment Trust (SASFIT) were parties to a dispute concerning a construction contract for a shopping centre. The case reached the High Court of Australia.

The High Court was required to determine whether Leighton had validly exercised its right to terminate the contract due to alleged breaches by SASFIT, specifically concerning delays in providing access to the site and the provision of plans. A key issue was whether SASFIT's conduct amounted to a repudiation of the contract, thereby entitling Leighton to terminate.

The Court considered the principles of repudiation, which requires a party to evince an intention no longer to be bound by the contract or to fulfil it only in a way that is inconsistent with its obligations. Deane, Toohey and Gaudron JJ found that SASFIT's conduct, while causing delays and inconvenience to Leighton, did not demonstrate a clear intention to abandon the contract or to perform it in a fundamentally different manner than agreed. The Court held that the delays and failures, though significant, did not amount to a repudiation that would justify Leighton's termination of the contract.

Consequently, the High Court found that Leighton had wrongfully repudiated the contract by purporting to terminate it.
