Represented enrolled members of the Comanche, Caddo, Apache, Cherokee, and Kiowa Tribes of Oklahoma, who own a trust allotment outside of Anadarko, Oklahoma, in actions for trespass and condemnation arising from the continued operation of a natural gas pipeline for more than sixteen years after the easement expired.

We obtained dismissal of the gas company’s condemnation claims, and the federal district court for the Western District of Oklahoma entered summary judgment against the gas company for trespass. On appeal, the Tenth Circuit affirmed the dismissal of the condemnation claims and affirmed summary judgment on trespass. Marcia W. Davilla, et al. v. Enable Midstream Partners, L.P., et al., No. 5:2015cv01262 (W.D. Okla. 2016); Marcia W. Davilla, et al. v.
