Supreme Court Backs Michigan in Line 5 Pipeline Fight

The Great Lakes just got a major champion in their corner. The U.S. Supreme Court ruled unanimously that Michigan's fight to shut down the Line 5 pipeline belongs in state court, clearing a crucial legal hurdle that could finally protect the waters connecting Lake Michigan and Lake Huron.

The decision ends years of delay tactics by Enbridge Energy, the Canadian company that operates the 645-mile pipeline carrying crude oil and natural gas beneath the Straits of Mackinac. Michigan Attorney General Dana Nessel has been fighting since 2019 to revoke the easement allowing the pipeline to cross this critical waterway, citing the constant threat of an oil spill.

Justice Sonia Sotomayor wrote for the unanimous court that Enbridge waited too long to move the case to federal court. The company's arguments weren't persuasive enough to override Michigan's authority to manage its own natural resources.

Legal experts are calling the unanimous ruling a big deal. "The justices of the court, regardless of ideology, agreed that it's the state court that's the proper court to hear this dispute," said Andy Buschbaum, a lawyer for the Great Lakes Business Network.

Now state courts can finally answer the question that matters most: does this aging pipeline belong on the bottom of the Great Lakes?

The ruling also creates important space for tribal voices. All 12 federally recognized tribes in Michigan have called for Line 5 to be shut down, saying it threatens their waters, treaty rights, and cultural ways of life.

"It will really create space now for tribes to uplift their voices in the proceedings," said Whitney Gravelle, president of the Bay Mills Indian Community. The tribes weren't part of the Supreme Court proceedings but will now have their day in state court.

The Ripple Effect

This decision reaches far beyond one pipeline case. It affirms that states have the power to protect their natural resources, even when international interests push back.

The ruling strengthens the voices of communities who live closest to environmental risks. For the tribes of Michigan, it means their treaty rights and traditional ways of life finally get full consideration in court decisions.

And for the millions of people who depend on the Great Lakes for drinking water, recreation, and their livelihoods, it means their state officials can fight for their protection without being pushed into federal courts where corporate interests often hold more sway.

The case still faces more legal hurdles before any final decision on the pipeline's future. But for the first time in years, the path forward is clear and the right court will make the call.

Michigan's waters just got a whole lot safer.
