The binding legal principles established are: (1) The right of appeal to the High Court under section 361 of the Mines and Minerals Act is not ousted by the right to appeal to the Minister under section 50(2), and the High Court retains discretion to entertain matters before domestic remedies are exhausted, particularly where the matter involves compliance with High Court orders. (2) Administrative decisions in mining disputes must be based on empirical evidence, particularly ground surveys, and cannot be made in contradiction of such evidence without contrary scientific evidence. (3) The principle 'first in time, first in right' (qui prior est tempore potior est jure) applies only in situations of double or multiple allocations of mining claims, not in cases of encroachment where a ground survey establishes that claims are located at different positions. (4) Mining registrations acquired after a forfeiture cannot be cancelled without setting aside or addressing the validity of the underlying forfeiture.
