This appeal concerns the proper exercise of the executive right of a mineral estate. The suit is one of several suits filed in the controversy among the various parties. The present suit was filed by J. C. Guerra and others against Clinton Manges, Gas Producing Enterprises and the Bank of the Southwest National Association. Clinton Manges and several members of the Guerra family were mineral co-tenants, with Manges holding the executive right to all the minerals. The Guerras sued Manges for failure to exercise diligence in leasing the minerals to third persons and for leasing a portion of the minerals to himself at allegedly unfair terms. The trial court rendered judgment removing Manges as holder of the executive rights; canceling a lease Manges executed to himself; voiding, as to the Guerras interests, certain transactions between Manges and third parties; and awarding the Guerras $382,608.79 in actual damages and $500,000 in exemplary damages. The court of civil appeals affirmed the judgment of the trial court. 621 S.W.2d 652.
