Zauner Construction Pty Ltd v No 2 Pitt Street Pty Ltd

Zauner Construction Pty Ltd initiated legal proceedings against No 2 Pitt Street Pty Ltd concerning a building contract. The dispute centred around a progress claim made by Zauner, which was followed by a late certificate issued by No 2 Pitt Street. The issue in contention was whether Zauner was obligated to pay the amount claimed in the progress claim or if the subsequent valid certificate altered this obligation.

The primary legal issue before the court was the interpretation of the contract in light of the late certificate. The court was required to determine whether the late issuance of the certificate by No 2 Pitt Street Pty Ltd affected the obligation to pay the amount claimed by Zauner Construction Pty Ltd. Additionally, the court had to consider whether a subsequent valid certificate could adjust the obligation to pay the amount certified, less any previous payments.

The court examined the contractual provisions and relevant sections of AS2124-1992, specifically clauses 42.1 and 44.9. It concluded that a late certificate does not absolve the obligation to pay the amount claimed initially. However, a subsequent valid certificate adjusts the obligation to pay the amount certified, less any payments already made. This interpretation was consistent with the intention of the parties as expressed in the contract. The court ruled in favour of No 2 Pitt Street Pty Ltd, stating that Zauner Construction Pty Ltd was obligated to pay the amount certified in the subsequent valid certificate, minus any payments already made.
