Copper Mines of Tasmania Pty. Ltd. (Agreement) Act 1999 (TAS)

In the matter of the Copper Mines of Tasmania Pty. Ltd. (Agreement) Act 1999, the case involved the approval and ratification of an agreement between the Crown in right of the State of Tasmania and Copper Mines of Tasmania Pty. Ltd. The agreement pertained to mining and mineral processing operations at Mt. Lyell, and the case was heard in the Tasmanian Parliament. The primary dispute centred around the ratification of the agreement and the legal implications of its provisions, particularly concerning environmental protection and liability.

The court was tasked with determining the legality and enforceability of the agreement, examining whether the agreement's provisions were consistent with existing laws and whether the protections afforded to the parties were lawful. Additionally, the court needed to decide whether the modifications to state laws, as required by the agreement, were valid and enforceable. The court also had to consider whether the protections from liability granted to certain parties were consistent with environmental protection standards and whether the repeal of previous legislation was justified.

The court found that the agreement was valid and enforceable, with the provisions having the force of law. The modifications to state laws were deemed necessary to give effect to the agreement and were held to be lawful. The court also ruled that the protections from liability were consistent with the agreement's terms and did not contravene environmental protection laws, except in cases of negligence or wilful misconduct. The repeal of the previous legislation was justified as it aligned with the new agreement's terms and objectives.

The court approved the ratification and implementation of the agreement, authorised the Crown to enforce the agreement, and modified state laws as necessary to give effect to the agreement. The court further held that the agreement was enforceable against the Crown by indemnified persons and that the protections from liability were valid, except in cases of negligence or wilful misconduct. The court declared that the project was no longer of state significance and that the relevant environmental protection notice was valid. Finally, the court repealed the previous legislation, replacing it with the new act.
