Goodman v Zhao

In the Federal Court of Australia, the plaintiff, Goodman, brought an action against the defendant, Zhao, concerning a construction dispute. The plaintiff alleged that Zhao had failed to complete works to the required standard and had delayed completion, resulting in a claim for liquidated damages. Zhao, on the other hand, sought to recover the balance of monies owed under the contract, along with damages for the plaintiff's alleged defective work. The court was required to determine the parties' common contractual intention and assess the validity of the claims and cross-claims.

The central issue was whether the contract documents, which included plans, specifications, and a contract, represented the complete agreement between the parties. The plaintiff argued that the contract documents did not accurately reflect the parties' agreement, while the defendant maintained that the written documents were the complete and exclusive statement of the agreement. The court had to decide if the written contract documents accurately captured the parties' intentions or if there were additional terms or modifications that needed to be considered. Additionally, the court needed to assess the validity of the claims for defective work, liquidated damages for delay, and the cross-claim for outstanding payments.

The court found that the contract documents did not fully represent the parties' agreement, as there were additional oral modifications and clarifications. The court examined the conduct of the parties and the surrounding circumstances to ascertain the common intention of the parties. The court determined that the plaintiff's claims for defective work were not substantiated and dismissed the cross-claim for outstanding payments. However, the court found that the defendant had delayed the completion of the works, and the plaintiff was entitled to liquidated damages for the delay. The court calculated the quantum of the liquidated damages and awarded the plaintiff $157,847.30 plus interest. The court reserved the decision on costs.
