Regulation 110(3) of the Mining Regulations 1981 (WA) has its ordinary meaning: no dealing, including one creating an equitable interest, is effectual to pass any estate or interest in a mining tenement until registered. The Barry v Heider read-down applicable to Torrens System legislation does not apply to mining tenement registration. The 'user principle' exception to compensatory damages does not apply where the plaintiff's entitlement is to a limited quantity of a resource and sufficient quantity remains after the wrongful taking to satisfy the full entitlement.
