John Holland Pty Ltd v Cardno MBK (NSW) Pty Ltd

The case of John Holland Pty Ltd v Cardno MBK (NSW) Pty Ltd was heard in the New South Wales Supreme Court. The dispute involved a challenge to an adjudicator's determination under the Building and Construction Industry Security of Payment Act 1999. The primary issue was whether the adjudication response must be tied to the payment schedule and whether the adjudication application must also be tied to the payment claim. Specifically, the court needed to decide if the adjudicator had the authority to consider reasons for withholding payment that were not included in the payment schedule, and whether the adjudicator could rely on reasons supporting the payment claim that were not included in the payment claim.

The court examined the statutory scheme of the Security of Payment Act, focusing on the role and powers of the adjudicator. The court determined that under Section 20(2B), an adjudication response must be tied to the payment schedule, meaning that any reasons for withholding payment must have been included in the payment schedule. Furthermore, the court found that the adjudication application must also be tied to the payment claim. The adjudicator does not have the power to consider materials or reasons in the adjudication application that were not included in the payment claim. The court concluded that the adjudicator's role is limited to the materials and reasons presented in the payment claim and the payment schedule.

The Supreme Court ruled in favour of John Holland Pty Ltd, stating that the adjudicator's determination was invalid because it relied on reasons not included in the payment schedule and the payment claim. The court held that the adjudicator exceeded their powers by considering external materials not provided within the scope of the payment claim. The decision was a significant clarification of the adjudicator's role and the scope of their authority under the Security of Payment Act. The court's ruling emphasized the importance of adhering strictly to the statutory requirements and the need for precise alignment between the payment claim, payment schedule, and adjudication application.
