Background
The case arose from the breakdown of a property-development venture between entities associated with builder Thomas Cull and developer Vaughan Blank. STM123 acquired a 50% interest in TC Build, later renamed Alta Vale Residential, and related STM123 project companies engaged the builder on cost-plus contracts. Although the projects initially carried an 8% builder’s margin, the principals later agreed to reduce the margin to 3%, but disputed the duration and effect of that arrangement.
After the builders issued payment claims in June 2022 seeking an 8% margin, the STM123 entities did not pay and the builders ceased work. Hoz Construction completed the unfinished projects. Alta Vale and TC Build Group pursued claims concerning unpaid costs and margin, suspension and termination, lost profits, contractual restraints, and alleged assistance in fiduciary breaches. The defendants cross-claimed over alleged defects, oppression, set-off, and damage associated with construction work at a neighbouring property.
The Court’s Holding
Nixon J determined the factual and legal issues necessary to resolve the parties’ competing claims, including the contractual arrangements governing project costs and margins, responsibility for the breakdown of the construction relationships, alleged defects, corporate and fiduciary-duty claims, statutory building-duty allegations, and asserted rights of set-off. The Court deliberately did not decide hypothetical issues that ceased to matter once other findings had been made.
The judgment did not itself record a final quantified award or comprehensive set of dispositive orders. The Court discharged Order 5 made by Peden J on 22 April 2026 and directed the parties to submit agreed orders giving effect to the reasons by 7 August 2026. If agreement could not be reached, each side was required to provide its proposed orders, limited submissions, and evidence concerning costs.
Key Takeaways
- Cost-plus construction arrangements should state clearly whether any reduced margin is temporary, retrospective, or project-specific.
- When former business partners give conflicting accounts of old conversations, contemporaneous documents, objectively established facts, and commercial probabilities can be decisive.
- In complex litigation involving interdependent claims, a court may determine the substantive issues in reasons while leaving the precise monetary relief and costs orders for a later process.
Why It Matters
The decision illustrates how a construction-payment dispute can expand into interconnected claims involving contract formation and termination, statutory suspension rights, defects, fiduciary obligations, shareholder oppression, and insolvency set-off. Lawyers structuring joint builder-developer ventures should ensure that project contracts, shareholder arrangements, margin variations, and responsibility for defects are documented consistently.
It also cautions readers not to treat reasons for judgment as a final executable outcome where the court has directed the parties to formulate consequential orders. The ultimate allocation of monetary liability and costs depended on the orders to be settled after judgment.
