Abacus v Davenport

The case of Abacus v Davenport dealt with a dispute between a construction company, Abacus, and an engineer, Davenport, over payment disputes under the Building & Construction Industry Security of Payment Act. The case was heard in the Supreme Court of Victoria. The primary issue before the court was whether the engineer had the authority to make a binding determination on payment disputes under the Act and, if so, what remedies were available if that determination was legally flawed.

The court had to determine whether, and under what circumstances, prerogative relief could be sought against an adjudicator's determination made pursuant to the Act. Specifically, the court needed to consider whether errors of law on the face of the record constituted a jurisdictional error that would allow for such relief. The court also examined whether the determination contained fundamental errors of law that rendered it void, and if so, whether this would allow for the engineer to be compelled to re-evaluate the dispute.

The court concluded that an adjudicator's determination under the Act could be subject to prerogative relief if it contained jurisdictional errors, such as errors of law that went to the adjudicator's authority or the process by which the decision was made. However, the court found that the determination in question did not contain such errors. It was held that the adjudicator had jurisdiction to make the determination and that it was not void for any error of law. Consequently, the court dismissed Abacus's application for prerogative relief, holding that the adjudicator's determination was valid and binding.

The court ordered that Abacus pay the amount determined by the adjudicator, subject to the usual right of recourse through the courts for review of the merits of the determination. This decision underscored the limited scope of prerogative relief in relation to adjudicators' determinations under the Act, emphasizing the importance of the merits-based review process.
