Tan Hung Nguyen v Luxury Design Homes Pty Ltd

The appeal concerned a dispute between Tan Hung Nguyen (the appellant) and Luxury Design Homes Pty Ltd (the respondent) regarding progress payments under a building contract. The matter came before the District Court of New South Wales, where a referee was appointed under Part 28B of the District Court Rules 1973 to report on the issues. The trial judge adopted the referee's report, leading to the appellant's appeal against the reasons given in the judgment.

The primary legal issues before the court were the proper construction of the building contract, particularly concerning the second progress payment, the sufficiency of the reasons provided in the judgment, and the correct approach to the calculations of amounts due. Further issues included the interpretation of a termination clause, whether the contract was an "entire contract" such that entire performance was a condition precedent to payment, and the application of the rule in *Sumpter v Hedges* to exclude common law rights to relief for repudiatory conduct.

The court considered the contract's terms to determine the parties' intentions regarding payment obligations and the consequences of non-performance. It analysed whether the contract mandated entire performance before any progress payment was due, referencing the principles established in *Sumpter v Hedges* concerning entire contracts and the right to payment. The court also examined the termination clause to ascertain its scope and effect. The reasoning focused on the contractual provisions and established legal principles governing building contracts and payment structures.

The appeal was dismissed, and the appellant was ordered to pay the respondent's costs.
