Bay, et al. v. Anadarko E&P Onshore, et al., No. 21-1361 (10th Cir. 2023)Annotate this Case
Marvin and Mildred Bay (“the Bays”) challenged a court order dismissing their trespass claim against Anadarko E&P Onshore LLC and Anadarko Land Corporation (collectively, “Anadarko”). Anadarko, an oil and gas company, owned the mineral rights under the Bays’ farm. The Bays brought a putative class action along with other surface landowners against Anadarko, alleging that Anadarko’s mineral lessees had exceeded the scope of their mineral rights by drilling multiple vertical wells on the surface owners’ land when it was possible to drill fewer wells of the “directional” type. At the conclusion of the Bays’ presentation of evidence, the district court found that the Bays’ evidence failed as a matter of law to demonstrate that Anadarko’s activities amounted to a trespass and dismissed the case. Finding that the district court applied the wrong legal standard, the Tenth Circuit reversed the dismissal in "Bay I," finding that Colorado’s common law of trespass required the Bays to show that Anadarko’s lessees had “materially interfered” with the Bays’ farming operations. The appellate court questioned whether the record demonstrated that the Bays met this standard in their trial, but because Anadarko had not raised this specific issue, the case was remanded to the district court for further proceedings. On remand, the district court again granted judgment as a matter of law to Anadarko on the material interference issue. Specifically, the court first held that it was bound by the Tenth Circuit's interpretation in Bay I of the material interference standard, then found that the Bays showed only that Anadarko’s conduct inconvenienced them—which was insufficient to satisfy the material interference standard. The Bays again appealed, arguing that the Tenth Circuit's discussion of the material interference standard in Bay I was dictum; thus, the district court incorrectly determined that it was bound to apply that standard. They further argued the material interference standard applied by the district court was inconsistent with the Colorado standard for trespass outlined in Gerrity Oil & Gas Corp. v. Magness, 946 P.2d 913 (Colo. 1997), and that the evidence they presented in their trial established a prima facie case of material interference under Gerrity. The Tenth Circuit determined the district court did not err in its second dismissal and affirmed judgment.
