Concho Resources, Inc. v. Ellison (Corrected)Annotate this Case
The Supreme Court reversed the judgment of the court of appeals reversing the trial court's grant of summary judgment for Defendants in this trespass-to-try-title suit between the lessees of adjacent mineral estates, holding that the court of appeals erred.
In its complaint, Plaintiff claimed that Defendants drilled wells either on Plaintiff's leasehold or closer to the lease line than allowed by Railroad Commission rules. Defendants argued in response that Plaintiff ratified an agreed boundary line, foreclosing Plaintiff's trespass claims. The trial court granted summary judgment for Defendants. The court of appeals reversed, concluding that a boundary stipulation between the fee owners of the two mineral estates, which Plaintiff accepted, was void and could not be ratified. The Supreme Court reversed, holding that the boundary stipulation was valid and that Defendants conclusively established their ratification defense.
