The matters in s 31(2)(a) of the Construction Contracts Act 2004 (WA) are jurisdictional facts in the 'broad' sense, meaning a court reviewing an adjudicator's finding on compliance with s 26 does not inquire into whether the application was in fact served in time, but only whether the adjudicator's conclusion was unreasonable, based on misconstruction, or affected by irrelevant considerations. A contractual right of setoff does not constitute 'payment' under s 39(1) of the Act, so a party cannot resist enforcement of a determination on the basis that the determination sum has been satisfied by setoff. Section 45(3) does not prohibit the use of adjudication materials in proceedings challenging the validity of a determination.
