Under the Construction Contracts Act 2004 (WA), a contract that includes both 'construction work' and excluded work (such as mining work) is a 'construction contract' and the duty to dismiss under s 31(2)(a)(i) does not arise. However, an adjudicator's jurisdiction under s 31(2)(b) is limited to determining 'payment disputes' as defined, and an adjudicator who erroneously determines a claim for payment for work that is not 'construction work' commits jurisdictional error. Such error does not void the entire determination where the affected portion is severable under common law principles. The question of whether there is a de minimis threshold for a contract to qualify as a 'construction contract' was left open.
