Atok-Big Wedge Mining Company v. Court of Appeals

Summary

ATOK-Big Wedge Mining Company sought to eject Liwan Consi from mineral land covered by a valid mining claim established in 1930-1931. Consi constructed a house in 1964 and claimed long-term family occupation. The Municipal Trial Court dismissed the case, but the Regional Trial Court reversed, ordering ejectment. The Court of Appeals found both parties had equal possessory rights. The Supreme Court reversed the CA, holding that a valid mining claim segregates land from the public domain and grants the locator exclusive rights superior to subsequent occupants. The Court applied Civil Code Article 538, favoring ATOK as the longer possessor (since 1931 vs. 1964), and ruled that possession of mineral land as agricultural land cannot defeat mining rights. The decision clarified that perfected mining claims create private property rights without need for patents.
