Snook and Western Australian Planning Commission

The matter involved Snook and the Western Australian Planning Commission, heard in the Western Australian Civil and Administrative Tribunal. The dispute centred on the resolution of planning issues through mediation, with a focus on whether issues previously resolved in mediation could be reintroduced into the proceeding. The central issue was whether the parties' agreement reached in mediation could be expanded upon in the Tribunal proceeding, despite the mediation process having largely resolved the disputes between them.

The court had to determine the legal principles governing the role of mediation in administrative proceedings and whether issues resolved in mediation could be reopened in the Tribunal. It considered the objectives of the Tribunal, the nature of mediation, and the terms of the mediation orders. The court needed to balance the finality of mediation agreements with the procedural flexibility required to achieve justice in individual cases.

In reaching its decision, the court examined the nature of the mediation process and its objectives. It noted that mediation was designed to facilitate dispute resolution, often resulting in agreements that are final and binding unless the parties expressly agree otherwise. The court found that the mediation had effectively resolved most of the issues, leaving only a single issue in dispute, which was clearly defined in the mediation orders. The court held that reopening issues resolved in mediation would undermine the purpose of the mediation process and the objectives of the Tribunal. Consequently, the application to expand the issues in the proceeding was dismissed, affirming the finality of the mediation agreement and the role of mediation in achieving the Tribunal's objectives.
