Irwin v Meander Valley Council

Irwin brought a case against the Meander Valley Council in the court, seeking judicial review of the council's decision to deny her application to build a shed. The primary issue before the court was whether the statutory framework governing the council's decisions precluded the application of common law principles of natural justice, specifically the rule against bias. Irwin argued that the council's decision-making process was flawed due to an apprehended bias on the part of one of the council members. The court needed to determine whether statutory provisions could exclude the common law principles of procedural fairness and, if so, under what circumstances.

The court examined the relevant legislation and found that it did not explicitly exclude the common law principles of natural justice. The court considered the purposive approach to statutory interpretation and concluded that the legislature did not intend to displace the common law principles of procedural fairness and the rule against bias unless such an intention was clearly expressed. The court held that the common law principles continue to apply unless the statute explicitly states otherwise. The apprehension of bias was found to be a valid ground for judicial review, and the council's decision was quashed due to the failure to observe the rule against bias.

The court ordered the council to reconsider Irwin's application for a shed, with a properly constituted decision-making body that did not include the member who was perceived to be biased. The court also noted that the council should ensure that its decision-making processes are transparent and free from any apprehension of bias in the future. The decision emphasised the importance of procedural fairness in administrative decision-making and the need for authorities to be mindful of the potential for bias.
