BSA Advanced Property Solutions (Fire) Pty Ltd v Ventia Australia Pty Ltd

The Court of Appeal of New South Wales considered a dispute between BSA Advanced Property Solutions (Fire) Pty Ltd (BSA) and Ventia Australia Pty Ltd (Ventia) concerning an adjudication under the *Building and Construction Industry Security of Payment Act 1999* (NSW). Ventia had served a payment claim on BSA, which BSA contended was invalid. The primary judge had found in favour of Ventia, and BSA appealed.

The central legal issues before the Court of Appeal were whether the "one contract" rule, which requires a payment claim to arise under a single contract, applied to condition the validity of a payment claim, and whether the contractual arrangements between the parties constituted one or multiple contracts. The Court also considered the statutory interpretation of the Act, particularly regarding jurisdictional constraints on adjudication and the legislative purpose of facilitating payment flow to subcontractors.

The Court of Appeal reasoned that the "one contract" rule, as previously understood, was not a jurisdictional prerequisite for the validity of a payment claim under the Act. Instead, the focus of the Act is on work performed under a construction contract, and a payment claim need not precisely identify the source of the entitlement, but rather refer to putative entitlements. The Court found that the contractual provisions, which stated that each work order constituted a new agreement, were inconsistent with other provisions and that the parties' characterisation of the arrangement was not determinative. Ultimately, the Court concluded that the primary judge had erred in her interpretation of the Act and the contractual arrangements.

The Court of Appeal allowed BSA's appeal, setting aside the orders of the Equity Division and dismissing Ventia's proceedings with costs. Ventia was also ordered to pay BSA's costs in the Court of Appeal.
