Mineralogy Pty Ltd v Chief Executive Officer, Department of Environment Regulation

Mineralogy Pty Ltd sought judicial review of a decision by the Chief Executive Officer of the Department of Environment Regulation to amend a desalination licence. The amendment in question allowed for the transhipment of water from one location to another, which Mineralogy argued would affect its operations and interests adversely. The dispute centred on the legality of the Chief Executive Officer's actions in amending the licence and whether the decision-making process complied with statutory requirements. The court was tasked with determining whether the Chief Executive Officer had the authority to amend the licence and whether they could reasonably have formed the opinion that Mineralogy had no direct interest in the subject matter of the licence or its amendment. Additionally, the court examined whether the decision was invalid due to non-compliance with a specific section of the Environmental Protection Act 1986 (WA) and whether there was an inconsistency between a Ministerial Statement and the amendment of the licences.

The court addressed the legal issues by first examining the statutory framework governing the powers of the Chief Executive Officer and the requirements for amending licences. It found that the Chief Executive Officer did indeed have the authority to amend the licence as per the provisions of the relevant legislation. The court then considered whether the Chief Executive Officer could reasonably have formed the opinion that Mineralogy had no direct interest in the subject matter. It concluded that the evidence supported the Chief Executive Officer's view, thus upholding the decision. The court further assessed whether the decision-making process complied with the statutory requirement and found no procedural flaws that would render the decision invalid. Lastly, the court examined the alleged inconsistency between the Ministerial Statement and the grant or amendment of the licences, concluding that no such inconsistency existed.

In light of the findings, the court dismissed Mineralogy's application for judicial review. The orders reflected this outcome, with the application being formally dismissed and no further judicial intervention deemed necessary. This decision affirmed the Chief Executive Officer's actions and the legality of the amended licence.
