Metgasco Limited v Minister for Resources and Energy

In Metgasco Limited v Minister for Resources and Energy, Metgasco challenged the Minister for Resources and Energy’s decision to suspend its mining operations under section 22(3A) of the Petroleum (Onshore) Act 1991 (NSW). The Minister had acted through a delegate who determined that Metgasco's operations posed a risk to the environment and public safety. The case was brought before the Supreme Court of New South Wales, which was tasked with reviewing the legality of the Minister's decision.

The legal issues before the court involved whether the Minister's decision was made according to law and whether the court should grant certiorari to quash the decision. Metgasco argued that the Minister had not followed the statutory criteria in making the decision and had acted without proper consideration of relevant evidence. The court was required to determine whether the Minister had adhered to the legislative requirements and if there were any procedural errors that warranted judicial intervention.

The court examined the statutory provisions and the decision-making process undertaken by the Minister's delegate. It found that the Minister had correctly identified the statutory criteria but failed to consider all relevant evidence. The court held that the Minister's decision contained an error of law as it did not appropriately weigh all the evidence, and thus the decision was not made according to law. Consequently, the court granted certiorari to quash the Minister's decision.

The final orders of the court included a declaration that the Minister's decision to suspend Metgasco's mining operations was unlawful. The court quashed the decision and remitted the matter to the Minister for reconsideration in accordance with the statutory requirements.
