Abigroup Contractors Pty Ltd v Multiplex Constructions Pty Ltd

Abigroup Contractors Pty Ltd sought to have certain claims for payment made by Multiplex Constructions Pty Ltd, a subcontractor, cancelled. The dispute arose under a building and engineering contract. The matter was heard by the Supreme Court of New South Wales. The primary issue for determination was whether the claims made by Multiplex were valid charges under the Subcontractors’ Charges Act 1974, specifically whether they constituted claims for money payable or to become payable under the subcontract and if those claims were governed by a provision of the subcontract that had not yet been complied with.

The court examined the nature of the claims made by Multiplex, considering whether they related to money payable or to become payable under the subcontract and if there were any conditions precedent that had not been fulfilled. The court found that the claims were for uncertified amounts and that the payment of these amounts was subject to certain conditions within the subcontract that had not been met at the time the claims were made. As such, the court determined that the claims did not constitute valid charges under the Act. The court concluded that the claims for money were not yet payable as they were contingent on the satisfaction of conditions within the subcontract, which had not been complied with.

In light of the findings, the court ordered that the notices of claim of charge dated 1 April 2003 and 2 May 2003 issued by Multiplex be cancelled pursuant to section 21 of the Subcontractors’ Charges Act 1974. This decision effectively disallowed Multiplex from enforcing the claims as charges against Abigroup until the conditions specified in the subcontract were met.
