District Court Stays Line 5 Shutdown Despite Trespass Finding, Citing Transit Treaty Obligations Over Tribal Sovereignty
District court stayed its June 16, 2026 shutdown injunction requiring Enbridge to cease operations on Line 5's 2.33-mile segment crossing Bad River Reservation despite finding the pipeline operator lacks valid easement and committed ongoing trespass on tribal lands. The stay pending Seventh Circuit appeal balances tribal sovereignty against international treaty obligations under the 1977 Transit Pipelines Treaty, with the court acknowledging no legal authority supports indefinite trespass but citing 'devastating impact' on energy trade.
Background
The Bad River Band of the Lake Superior Tribe of Chippewa Indians brought suit against Enbridge Energy over a 2.33-mile segment of Line 5 that crosses the Bad River Reservation in Wisconsin. The district court found that Enbridge lacks a valid easement for the pipeline segment and that its continued operation constitutes ongoing trespass on tribal lands. The pipeline's route through the reservation became the subject of litigation after the tribe challenged Enbridge's legal authority to maintain operations across sovereign tribal territory.
The District Court's Trespass Finding and Shutdown Injunction
The district court issued a June 16, 2026 shutdown injunction ordering Enbridge to cease Line 5 operations across the reservation segment. The court's ruling turned on its determination that Enbridge's easement rights had expired or were otherwise invalid, rendering the pipeline's continued presence an ongoing trespass on tribal lands. The injunction represented a complete remedy for the trespass—removal of the offending infrastructure from tribal lands. The court acknowledged that no legal authority supports allowing an indefinite trespass to continue, a principle that applies with particular force in the context of tribal sovereignty over reservation lands.
The Stay Pending Appeal
Despite its trespass finding, the district court stayed its own shutdown injunction pending Enbridge's appeal to the Seventh Circuit. The stay rests on the court's assessment of the 'devastating impact' that Line 5's shutdown would have on energy trade and local economies. The court balanced tribal sovereignty interests against international treaty obligations under the 1977 Transit Pipelines Treaty, which governs cross-border pipeline infrastructure between the United States and Canada. The court's decision to grant the stay reflects its weighing of the tribe's property rights against broader energy security and international relations concerns during the appellate process.
International Treaty Considerations
The court invoked the 1977 Transit Pipelines Treaty as part of its justification for staying the shutdown injunction. By referencing the treaty in its balancing analysis, the district court considered international treaty obligations alongside the remedies for trespass on tribal lands. This raises questions about the interaction between tribal sovereignty, property rights, and international treaty obligations in pipeline litigation.
