Here is the opinion. An excerpt:

Plaintiff Enable Oklahoma Intrastate Transmission, LLC, appeals the district court’s dismissal of its case for lack of subject matter jurisdiction and for failure to join an indispensable party. Enable also challenges the amount of attorney fees the court awarded to the landowner defendants. Because our decision in Public Service Company of New Mexico v. Barboan, 857 F.3d 1101 (10th Cir. 2017), is dispositive of the subject matter jurisdiction issue, we affirm the district court’s order dismissing the action. We likewise affirm the attorney fees award as consistent with Oklahoma law.
