Wyloo Metals Pty Ltd v Quarry Park Pty Ltd

Wyloo Metals Pty Ltd sought to impugn the grant of a mining lease to Quarry Park Pty Ltd, asserting that the lease was invalid due to non-compliance with statutory requirements and therefore, lacked jurisdiction. The dispute was heard in the Supreme Court of Western Australia. The central legal issues involved the interpretation of the Mining Act 1978 (WA), specifically whether the term 'dealing' in section 116(2) of the Act should be interpreted in its defined sense and whether the protection afforded by this section extends to a third party purchaser before they are registered as the holder of the mining lease. Additionally, the court had to consider whether the lapse of time between the invalid grant of the mining lease and the commencement of the proceedings was a sufficient basis for exercising the judicial discretion to refuse declaratory relief.

The court examined the statutory language and legislative history to determine the intended scope of section 116(2). It found that the definition of 'dealing' was introduced to align with the registration requirements under the Act and to maintain the correlation between registered transactions and the protection afforded by the statute. The court concluded that the term 'dealing' was indeed used in its defined sense within section 116(2), thereby excluding unregistered equitable interests from its protection. Consequently, the protection under section 116(2) did not extend to the third party purchaser until they were registered as the holder of the mining lease. The court also held that the lapse of time did not preclude declaratory relief, as the statutory provisions did not impose a time limit on such claims.

The court allowed the appeal, setting aside the primary orders and declaring the mining lease invalid. It further discharged the interim and interlocutory injunctions previously granted. This decision underscores the importance of statutory compliance in mining leases and the specific protections afforded by the Mining Act 1978 (WA).
