Section 9(a) of the Building and Construction Industry Security of Payment Act 1999 (NSW) is not a jurisdictional requirement; an adjudicator's misconstruction or misapplication of contractual provisions in calculating a progress payment is an error within jurisdiction, not amenable to judicial review for jurisdictional error. The obligation of good faith and natural justice must be assessed having regard to the magnitude of the task and the way the parties have framed the dispute; a party that fails to draw the adjudicator's attention to relevant material in voluminous documentation cannot complain that the adjudicator failed to deal with that material.
