Plaza West Pty Ltd v Simon's Earthworks (NSW) Pty Ltd

Plaza West Pty Ltd (the respondent) sought to enforce an adjudication certificate issued under the *Building and Construction Industry Security of Payment Act 1999* (NSW) against Simon's Earthworks (NSW) Pty Ltd (the appellant). The dispute concerned a payment claim made by the respondent for work carried out under a construction contract. The appellant sought to set aside the adjudication certificate, alleging various errors by the adjudicator.

The primary legal issues before the Court of Appeal were whether the adjudicator had committed an error of fact or law sufficient to vitiate the adjudication determination, whether the adjudicator had failed to fulfil their statutory task, and whether the appellant had been denied procedural fairness. The Court also considered whether the appellant's payment to a third party discharged its debt to the respondent.

The Court of Appeal held that the adjudicator had not made an error of fact or law that vitiated the determination. It was found that the adjudicator had properly considered the evidence before them and had undertaken the task required by the Act. Furthermore, the Court found no denial of procedural fairness to the appellant. The Court also determined that the appellant's payment to a third party did not discharge its debt to the respondent under the Act. Consequently, the appeal was dismissed with costs.
