Michigan Supreme Court Vacates Line 5 Tunnel Authorization

In a landmark decision issued July 31, 2026, the Michigan Supreme Court vacated the Michigan Public Service Commission’s authorization of Enbridge’s proposal to route its Line 5 pipeline through a tunnel beneath the Straits of Mackinac.
A coalition of Tribal Nations and environmental groups appealed the Commission’s approval, arguing that the agency failed to address the significant dangers posed by the project to the environment and the public trust in the Great Lakes. Kanji & Katzen represented Flow Water Advocates in an appeal focused on the important public trust issues in the case.
The Michigan Supreme Court agreed with the co-appellants and directed the agency to rigorously evaluate these harms on remand, including the harms to public trust resources such as the fisheries (both tribal treaty and non-Indian fisheries) and navigation, and the significant risk that perpetuation of Line 5’s lifespan through construction of the tunnel will lead to releases elsewhere along the span of the aging pipeline. The significance of this risk was driven home on August 25, 2026, when Line 5 ruptured and released at least 1.3 million gallons of natural gas liquids near Saxon, Wisconsin, just to the east of the Bad River Reservation.
The Michigan Supreme Court’s decision marks a crucial step in protecting the Great Lakes and tribal treaty rights from the threat of Enbridge’s proposed tunnel. It will also have important implications for Michigan environmental law more broadly. The decision confirms that state agencies have a responsibility to safeguard the public trust in their administrative decision making. And it holds that one of the state’s key environmental statutes—the Michigan Environmental Protection Act—requires agencies to engage in a searching analysis of environmental harms caused by a proposed project and to evaluate the project against alternatives in a fair and even-handed way.

Federal Appeals Court Holds that Enbridge Is Trespassing on Bad River Reservation

On July 30, 2026, the United States Court of Appeals for the Seventh Circuit held that Enbridge, a Canadian pipeline company, is trespassing on land belonging to the Bad River Band of the Lake Superior Tribe of Chippewa Indians and confirmed that the company must remove its pipeline from the Band’s Reservation.
Line 5 runs through twelve miles of sensitive habitat on the Bad River Reservation. The easements allowing Enbridge to maintain a right of way across the Reservation expired over a decade ago, but Enbridge has refused to remove its pipeline. In 2019, the Band filed suit against the company to end this unauthorized occupation. Last month, a unanimous panel for the Seventh Circuit agreed with the Band that Enbridge is in trespass. As the court held, “the Band exercises its sovereign power over the Bad River Reservation” and has the authority “to expel those who enter the reservation without proper authority.” The court’s decision is clear: “Enbridge must remove the pipeline.” The company must also pay the Band restitution for its years of intentional trespass.
The case will now return to the United States District Court for the Western District of Wisconsin for further proceedings to calculate the restitution award and determine the timeline for Enbridge to remove Line 5.

Federal Courts Reject Challenges to White Earth Water Protection Ordinance

The White Earth Reservation Groundwater and Surface Water Protection Ordinance requires all new high-capacity pumps and wells on the Reservation to be permitted by the White Earth Band of the Minnesota Chippewa Tribe. The White Earth Reservation Business Committee enacted the Ordinance to safeguard the waters, fisheries, wild rice, and other natural resources—resources that were guaranteed to the Band by treaty in 1867 and that sustain hundreds of Tribal members’ subsistence lifestyle—from the devastating effects of high-capacity water appropriations, primarily by non-Indian agricultural interests. On March 5, 2025, in Vipond v. DeGroat, 24-cv-03125 (D. Minn.), U.S. District Judge Katherine Menendez denied the plaintiff irrigator’s motion for a preliminary injunction to enjoin ongoing White Earth Tribal Court proceedings in which the Band seeks a declaration that the irrigator’s proposal to pump 65 million gallons of water each summer from the Wild Rice River is validly subject to tribal regulatory authority. Judge Menendez stayed the federal case pending the exhaustion of tribal court remedies. And on March 21, 2025, in R.D. Offutt Farms Co. v. White Earth Division of Natural Resources, 24-cv-01600 (D. Minn.), U.S. District Judge Jeffrey Bryan dismissed an industrial potato producer’s challenge to the Ordinance for lack of jurisdiction.

Washington Tribes Obtain Dismissal of Industry Lawsuit Challenging Water Quality Standards Protective of Sustenance Fishing

On March 19, 2025, the U.S. District Court for the District of Columbia dismissed a lawsuit brought by the Association of Washington Business (AWB) and other industry trade groups against the U.S. Environmental Protection Agency. The lawsuit challenged human health criteria that EPA promulgated for Washington waters to address pollution that has resulted in fish consumption advisories across the state. AWB argued that these federal water quality standards were too stringent because they correctly recognized that Washingtonians eat more fish than citizens in many other states (i.e., fish consumption rate of 175 g/day) and required that PCBs pose no greater risk of cancer to the population of Washington than any other toxic pollutant (i.e., cancer risk level of one in one million). The District Court dismissed the case as moot after the State of Washington adopted the federal human health criteria into state law and EPA approved the criteria under the Clean Water Act. Five Tribes and the State of Washington intervened in the lawsuit to defend the protective federal human health criteria and moved to dismiss the case as moot once they were adopted into state law.

Port Gamble S’Klallam Tribe and NRD Trustee Council Reach Settlement with Owners of Former Mill Site to Restore Habitats in Port Gamble Bay

The Port Gamble S’Klallam Tribe and the other members of the Port Gamble Bay Natural Resource Trustee Council have reached a settlement with the owners of the site of a former sawmill at the mouth of the bay to build two habitat restoration projects that are valued at nearly $10 million.

For 142 years, starting in 1853, Pope & Talbot, Inc. operated a sawmill on the property, which released hazardous substances into Port Gamble Bay that were harmful to fish, shellfish, migratory birds, and other organisms. In 2014, the Trustee Council was formed to assess harm to natural resources in the bay and to seek compensation for that harm. The Trustee Council includes the Port Gamble S’Klallam Tribe, the Jamestown S’Klallam Tribe, the Lower Elwha Klallam Tribe, the Skokomish Indian Tribe, the Suquamish Tribe, the U.S. Fish and Wildlife Service (representing the U.S. Department of the Interior), and the State of Washington (led by the Department of Ecology).

The settlement requires the current and former property owners, Pope Resources, OPG Properties LLC, and OPG Port Gamble LLC, to restore approximately nine acres of riparian habitat along the southern shoreline of the mill site, which will include removing hardscape, installing an intertidal cap, restoring the beach to near-natural slopes, and planting native vegetation. Additionally, the property owners will place sand cover and plant eelgrass over at least eleven acres of subtidal areas on the western side of the bay. The property owners will also provide funding for long-term maintenance and monitoring and permanent stewardship of the southern mill site to preserve the benefits of the habitat restoration in perpetuity. Approximately 30 acres in and around the bay will also be protected by easements that will prohibit activities that could harm the habitat projects.

The settlement, which takes the form of a Consent Decree, was approved by the United States District Court in the Western District of Washington on September 23, 2024. John Sledd, Jane Steadman, Reed Bienvenu, and other members of the Kanji & Katzen, P.L.L.C. team have represented the Port Gamble S’Klallam Tribe in connection with this matter for well over a decade. Kanji & Katzen congratulates the Tribe and the Trustee Council on this historic achievement, which will have tremendous benefits for Port Gamble Bay and for the people and wildlife that make the bay their home.
