WPX Energy Williston, LLC v. Honorable B.J. Jones

September 4, 2026

Summary

The Eighth Circuit vacated the district court's preliminary injunction and remanded, holding that the Three Affiliated Tribes District Court has jurisdiction over the dispute arising from the side‑letter agreements between WPX Energy and tribal members, that WPX Energy is unlikely to succeed on the merits of its jurisdictional claim, and that WPX Energy does not suffer irreparable harm.
