Adjudicators' determinations under the Building and Construction Industry Security of Payment Act 1999 (NSW) are final and binding between the parties as to the issues determined, attracting the principles of issue estoppel. A claimant dissatisfied with an adjudication cannot serve a further identical payment claim to obtain a redetermination. Section 13(5) operates as a prohibition such that a purported payment claim in respect of the same reference date as a previous claim is not a valid payment claim under the Act. Section 22(4) is not exhaustive of the binding effect of earlier determinations; all issues resolved by an adjudicator (including questions of entitlement, not just valuation) are binding in subsequent adjudications.
