In resolving disputes among the mineral interest family, there is no bright-line rule delineating the duty of the executive right holder. In Texas Outfitters Limited v. Nicholson, the Texas Supreme Court explained why. The Court last addressed executive rights in 2015 in KCM Financial v. Bradshaw, where the executive allegedly colluded with a lessee for lease terms favoring itself at the expense of the non-executive. Texas Outfitters presented an oppportunity for the Court to apply the KCM guidelines to a different scenario: whether the executive breached the duty by refusing to lease.
(Spoiler alert: Yes.)
