Bad River Band Files Legal Challenge Against Line 5 Reroute Approval in Wisconsin Court

By Joe Morey Rez Life Weekly Editor

The Bad River Band of Lake Superior Chippewa has filed a petition for judicial review in Wisconsin's Iron County Circuit Court, challenging a recent ruling that approved permits for Enbridge's proposed Line 5 pipeline reroute. The legal action contests Administrative Law Judge Angela Chaput Foy's decision to uphold Wisconsin Department of Natural Resources permits for the 41-mile project.

Tribal Chairwoman Elizabeth Arbuckle announced the filing alongside a motion for an immediate stay that would halt any construction activities until the court can hear the Band's legal claims.

“The Bad River watershed is not an oil pipeline corridor... It is our homeland. We must protect it,” Arbuckle said in a Feb. 20, 2026 statement reported by Wisconsin Public Radio (WPR). The Band is joined in its challenge by environmental organizations including Clean Wisconsin and the Sierra Club.

Line 5 has been operating on the Bad River Reservation without authorization for more than a decade. A federal court previously ruled the pipeline's presence unlawful and set a shutdown deadline of June 2026. The proposed reroute would create a new 41-mile section that encircles the northern Wisconsin reservation rather than crossing tribal lands.

The project has emerged as a flashpoint in debates over energy infrastructure, tribal sovereignty, and environmental protection in the Great Lakes region. Enbridge maintains that Line 5 supplies critical energy resources to Michigan's Upper Peninsula and parts of Wisconsin, and the company says its reroute plans minimize environmental risks while remaining vital to the regional economy, while opponents argue the pipeline poses unacceptable risks to water resources and violates treaty-protected rights.

The Bad River Band, represented by Earthjustice attorneys, argues that the permits were approved without adequate assessment of the project's environmental and cultural impacts.

John Petoskey, Senior Associate Attorney with Earthjustice, stated that the permit was "granted and then upheld without baseline information about the project's immediate and long-term impacts."

The Band contends that construction activities would involve blasting, trenching, and drilling through hundreds of upstream wetlands and waterways. These activities, tribal representatives assert, threaten to damage or destroy waters and ecosystems protected under federal treaties between the United States and the Lake Superior Chippewa.

Bad River Chairman Robert Blanchard has argued the stakes extend beyond the construction footprint, saying, “If Enbridge is allowed to move this nightmare upstream... our drinking water, our way of life, and our very future hang in the balance.”

Central to the legal challenge is the Band's assertion that the project violates tribal water quality standards, which are more stringent than those applied by the State of Wisconsin.

Blanchard has also criticized the state permitting decision, saying, “In my view, the DNR failed our children when it gave Enbridge the permits to build this reroute. As a tribal chairman and an elder, it’s my responsibility to protect the generations still to come.”

Under the Clean Water Act, federally recognized tribes can establish their own water quality standards for reservation waters.

Cultural and Environmental Concerns

The proposed pipeline route passes through areas containing traditional wild rice beds and critical habitat for fish species that tribal members rely on for subsistence and ceremonial purposes. The Bad River holds particular cultural and spiritual significance for the Band.

Wild rice, or manoomin in Ojibwe, is considered a sacred food in Anishinaabe culture and plays a central role in tribal ceremonies, traditional harvests, and food sovereignty efforts. The Band has raised concerns that construction activities and potential pipeline incidents could contaminate waters where wild rice grows, threatening both the plant's survival and the cultural practices tied to its harvest.

The watershed in question provides habitat for numerous fish species, including lake sturgeon, walleye, and native brook trout. These fisheries support both subsistence use by tribal members exercising treaty rights and commercial fishing operations that contribute to the local economy.

Economic and Energy Security Arguments

Proponents of the pipeline project, including the Wisconsin Building Trades Council, argue that the reroute would create approximately 700 union jobs during construction. Supporters also emphasize the pipeline's role in delivering propane and other petroleum products to communities in Michigan's Upper Peninsula and northern Wisconsin.

The Building Trades Council has characterized Line 5 as critical infrastructure for regional energy security, noting that many residents depend on propane for heating during harsh winter months. Industry representatives have stated that shuttering Line 5 without an alternative route could force increased reliance on truck and rail transportation, which they contend poses greater safety and environmental risks.

Enbridge has maintained that the proposed reroute represents a compromise that addresses concerns about the current pipeline's location while preserving the company's ability to continue operations. The company has committed to following state and federal permitting processes and has stated its willingness to work with regulatory agencies to address environmental concerns.

Parallel Federal Court Challenge

In addition to the state court petition, the Bad River Band has filed a separate lawsuit in federal court against the U.S. Army Corps of Engineers. That legal action challenges the Corps' issuance of permits under Section 404 of the Clean Water Act, which regulates discharges of dredged or fill material into waters of the United States.

The federal lawsuit alleges that the Army Corps failed to comply with the National Environmental Policy Act (NEPA) in its review of the project. NEPA requires federal agencies to assess the environmental impacts of major federal actions and consider alternatives before making decisions.

The Band's federal complaint argues that the Corps did not adequately analyze the cumulative impacts of the project on wetlands, streams, and downstream waters. The lawsuit also contends that the agency failed to properly consult with the Tribe regarding impacts to treaty-protected resources, as required under federal trust responsibilities.

The legal challenges come amid heightened national attention to pipeline projects crossing or near tribal lands and sacred sites. Recent years have seen numerous conflicts over energy infrastructure, including the prolonged protests against the Dakota Access Pipeline and ongoing disputes over other projects affecting Indigenous communities.

Legal scholars and tribal advocates have increasingly emphasized the importance of meaningful consultation with tribes and respect for treaty rights in infrastructure permitting decisions. The Bad River case may establish precedents for how state and federal agencies must balance energy development interests against tribal sovereignty and environmental protection.

The case also highlights tensions between state-level environmental permitting and tribal regulatory authority. As federally recognized sovereign nations, tribes can establish environmental standards for their territories that differ from state regulations, creating complex jurisdictional questions when projects affect both tribal and non-tribal lands.

What Comes Next

The Iron County Circuit Court will consider the Band's motion for a stay, which seeks to prevent any construction from beginning while the legal challenges proceed. If granted, the stay would maintain the status quo until the court can fully review the merits of the Band's claims against the permit approval.

The timeline for the state court proceedings remains uncertain, though such cases typically require several months or longer to resolve. Meanwhile, the federal lawsuit against the Army Corps will proceed on a separate track in U.S. District Court.

With the June 2026 shutdown deadline for the current Line 5 route approaching, the legal proceedings could significantly impact Enbridge's plans and the broader energy supply situation in the Upper Great Lakes region. All parties face mounting pressure to resolve the dispute as the court-ordered deadline draws closer.

The Bad River Band has indicated it will continue pursuing all available legal remedies to protect tribal waters and treaty rights. Environmental groups supporting the Band's position have pledged to maintain their opposition to the project through both litigation and public advocacy efforts.
