David and Gai Spankie and Northern Investment Holdings Pty Ltd v James Trowse Constructions Pty Ltd (No. 2)

David and Gai Spankie, along with Northern Investment Holdings Pty Ltd, brought a case against James Trowse Constructions Pty Ltd, challenging a decision made by an adjudicator under the Building and Construction Industry Payments Act 2004 (Qld). The applicants, David and Gai Spankie and Northern Investment Holdings, were contesting a claim by the first respondent, James Trowse Constructions, which was upheld by the adjudicator. The applicants argued that the adjudicator's decision was fundamentally flawed because it was based on considerations that neither party had discussed during the proceedings, which they claimed breached the principles of procedural fairness.

The primary legal issue before the court was whether the adjudicator’s decision was void due to a breach of natural justice. The applicants contended that the adjudicator made a significant part of the decision based on an issue that was not presented or argued by either party, thus denying them a fair opportunity to respond and defend against it. The court needed to determine if the failure to address this issue amounted to a denial of procedural fairness.

The court found that the adjudicator's decision did indeed breach the principles of natural justice. The adjudicator had effectively decided on a matter that neither party had addressed, which deprived the applicants of a fair opportunity to present their case. This procedural flaw rendered the decision void. Consequently, the court declared the decision of the third respondent, dated 2 November 2009, in respect of the dispute between the applicants and the first respondent, to be void.
