On May 6, the Land and Environment Court at Umeå District Court announced that Copperstone was granted an environmental permit for the reopening of the Viscaria copper mine. The court has also granted Copperstone an enforcement order which means that certain time-critical processes can be initiated immediately, pending the judgment gaining legal force and the permit being fully used. The enforcement includes the construction and operation of water treatment plants and the drainage and rehabilitation of the existing underground mine.

The environmental permit covers the extraction of up to 3.6 million tonnes of ore per year and is subject to certain conditions regarding emissions to water and air, species protection, Natura 2000 and protection measures for reindeer husbandry. The judgement of the Land and Environment Court can be appealed to the Land and Environment Court of Appeal, MÖD, and then to the Supreme Court, which is the final instance. In order for an appeal to be considered by either of these courts, the court in question must grant leave to appeal.

When the MMD's decision cannot be further appealed, it becomes final. The deadline for appealing the Land and Environment Court's judgment is 27 May 2024.
