Onesteel Manufacturing Pty Ltd v Whyalla Red Dust Action Group Inc

Onesteel Manufacturing Pty Ltd sought judicial review of a decision by the Environment, Resources and Development Court, which dismissed the company's application for a civil enforcement order under the Environment Protection Act 1993. The Whyalla Red Dust Action Group Inc intervened in the proceedings, asserting their interests were affected by the subject matter of the application. The central legal issues revolved around the statutory criteria for standing and the granting of leave to intervene in judicial review proceedings.

The court had to determine whether the Whyalla Red Dust Action Group Inc's interests were indeed affected by the subject matter of the application and, if not, whether the group should be granted leave to intervene under the statute. The court examined the legislative provisions conferring standing and the criteria for granting leave, focusing on the requirement that the applicant's interests must be affected and the additional criteria for granting leave. The court also considered the impact of legislative changes made after the initial determination of the application.

The court concluded that the Whyalla Red Dust Action Group Inc did not meet the statutory criteria for standing as their interests were not affected by the subject matter of the application. Additionally, the court held that it was not appropriate to grant the group leave to intervene, as they failed to satisfy the rigorous test for leave. The appeal was allowed, and the decision of the Environment, Resources and Development Court was set aside. In lieu thereof, the court ordered that Onesteel Manufacturing Pty Ltd's application for a civil enforcement order under section 104 of the Environment Protection Act 1993 be dismissed.
