The 5th Circuit Court of Appeals in New Orleans has ruled for Chesapeake in two cases, holding that it can deduct post-production costs from gas royalties. Potts v. Chesapeake Exploration, No. 13-10601, and Warren v. Chesapeake Exploration, No. 13-10619. Both cases were decided by the same three judges, and both opinions were written by Judge Priscilla R. Owen. In both cases, Judge Owen relied on the Texas Supreme Court case of Heritage Resources v. NationsBank, 939 S.W.2d 118 (Tex. 1996). Judge Owen was on the Texas Supreme Court when Heritage v. NationsBank was decided, and she wrote an opinion in that case. Judge Owen cites her own opinion in Heritage as the principal precedent for her opinions in Potts and Warren.
The Potts and Warren cases were tried in federal district court. Because Chesapeake’s home office is in Oklahoma, it has the right to remove suits filed against it in Texas to federal court. Federal courts have “diversity” jurisdiction over cases between citizens of different states. In diversity cases, federal courts must follow the law of the states. No federal law is involved. So, in deciding Potts and Warren, the 5th Circuit judges were attempting to predict what a Texas court would do, following prior precedent from Texas courts — in this case, Heritage v. NationsBank.
Heritage v. NationsBank is a seminal case in oil and gas law, some would say infamous. The question in Heritage was whether Heritage, the lessee, could deduct transportation costs for gas from royalties owed to NationsBank. NationsBank’s lease provided that royalties on gas would be “the market value at the well of 1/5 of the gas so sold or used, … provided, however, that there shall be no deductions from the value of the Lessor’s royalty by reason of any required processing, cost of dehydration, compression, transportation or other matter to market such gas.” The Texas Supreme Court held that Heritage could deduct transportation costs from NationsBank’s royalty. In her concurring opinion, Justice Owen said that the no-deductions proviso on NationsBank’s lease was “circular” and “meaningless”:
