In a significant legal victory for Michigan, the United States Supreme Court has ruled that the state’s lawsuit to shut down a segment of the ageing Line 5 pipeline will remain in state court. This decision is pivotal in a protracted legal battle concerning the pipeline, which has been transporting crude oil and natural gas liquids since 1953 beneath the Great Lakes’ Straits of Mackinac. The ruling is a crucial step in addressing environmental concerns and safeguarding the Great Lakes from potential ecological disaster.
Legal Struggles Surrounding Line 5
On Wednesday, the Supreme Court unanimously sided with Michigan, asserting that Enbridge Energy, the company operating the pipeline, had delayed too long in attempting to shift the case to federal jurisdiction. Justice Sonia Sotomayor, writing for the court, confirmed that the case, which originated from a lawsuit filed by Michigan Attorney General Dana Nessel in June 2019, will remain in the hands of state authorities. Nessel is seeking to nullify the easement that permits the operation of a 4.5-mile segment of Line 5 that runs under the straits connecting Lake Michigan and Lake Huron.
In June 2020, Nessel secured a restraining order from Ingham County Judge James Jamo that temporarily halted operations of the pipeline, although Enbridge was allowed to continue its activities after meeting specific safety protocols. The legal landscape changed in 2021 when Enbridge attempted to transfer the lawsuit to federal court, citing implications for U.S.-Canadian trade. However, a three-judge panel from the Sixth Circuit Court of Appeals ruled in June 2024 that Enbridge had missed a critical 30-day window to change jurisdictions.
Concerns About Environmental Safety
The pipeline in question, known as Line 5, has faced intense scrutiny over fears of a catastrophic spill. Concerns escalated significantly after revelations in 2017 that Enbridge engineers had been aware of protective coating gaps in the pipeline since 2014. The situation worsened in 2018 when a boat anchor damaged the pipeline, raising alarms about the potential for an environmental disaster.
In 2020, the Michigan Department of Natural Resources, under Governor Gretchen Whitmer, revoked the easement that allowed the pipeline to operate. While a federal judge subsequently issued a ruling that blocked the state’s revocation, Whitmer has appealed that decision, further complicating the legal landscape surrounding Line 5.
Ongoing Legal and Environmental Challenges
Enbridge is also pursuing permits to encase the section of the pipeline beneath the Straits of Mackinac in a protective tunnel. Although the Michigan Public Service Commission granted these permits in 2023, a coalition of environmental groups and Indigenous tribes has filed a lawsuit to challenge the state’s approval. The Michigan Supreme Court is currently deliberating over this case, which adds yet another layer to the ongoing dispute.
Compounding the situation, a separate legal case in Wisconsin has also emerged. A federal judge ruled last summer that Enbridge must cease operations on a segment of Line 5 that crosses the Bad River Band of Lake Superior’s reservation. Enbridge is appealing this shutdown order, but it has already begun rerouting the pipeline around the reservation, a move met with opposition from the Bad River Band and environmental advocates, who argue that the reroute will cause significant ecological damage.
Why it Matters
The Supreme Court’s decision to uphold Michigan’s jurisdiction over the Line 5 case is crucial not only for the state’s environmental integrity but also for the protection of the Great Lakes, a vital freshwater resource. As climate change intensifies and the world grapples with the impacts of fossil fuel dependence, the outcome of this legal battle could set a precedent for future energy infrastructure projects. It emphasises the growing need for accountability in energy operations and the imperative to prioritise environmental safety over corporate interests. The fight against Line 5 is emblematic of a broader struggle against outdated fossil fuel infrastructure that threatens our planet’s future.
