Imerva Corporation Pty Ltd v Kuna

Imerva Corporation Pty Ltd brought an action against Kuna in the Supreme Court of New South Wales, seeking a declaration and an injunction to enforce a contract for the construction of a building. The dispute centred on the interpretation of the contract's progress payment schedule and whether it was governed by the contract or by the Domestic Building Contracts Act 1995. The court was tasked with determining the legal framework governing progress payments and whether the parties could validly agree to a schedule that deviated from the statutory requirements.

The primary legal issue was whether the parties could effectively agree to a payment schedule that differed from the one prescribed by the Act, and if so, whether the agreement was properly executed. The court examined the statutory provisions and regulations that allowed parties to depart from the prescribed schedule, provided they did so in the manner outlined in the regulations. The regulations required a clear demonstration of the building owner's understanding of the change in legal rights, typically evidenced by a signed document. The court considered whether the signature on the document met this requirement and whether estoppel could prevent the owner from enforcing the statutory protection.

The court found that the signature on the document, which consisted only of initials, was insufficient to demonstrate the required understanding of the change in legal rights. The objective of the statutory requirement was to protect the consumer, and a mere initials were not a sufficient manifestation of this understanding. The court rejected the builder's argument that estoppel should preclude the owner from enforcing the statutory protection. The court held that the builder's contravention of the statutory requirements meant the owner could not be estopped from relying on the statutory provisions. The court granted leave to appeal, but ultimately dismissed the appeal.

The court's decision emphasised the importance of clear and unequivocal communication in altering statutory rights, particularly in consumer protection contexts. The court confirmed that the statutory requirement of a signed document was intended to ensure that the consumer fully understood the implications of any changes to their legal rights. The outcome underscored the need for builders to strictly adhere to the statutory requirements when negotiating changes to the prescribed payment schedule.
