In a significant legal development, the US Supreme Court has reaffirmed Michigan’s jurisdiction over a contentious section of the Line 5 pipeline, which traverses the Great Lakes. The unanimous ruling maintains that the state’s ongoing lawsuit aimed at halting operations of the ageing pipeline will remain in state court, a decision that has implications for environmental safety and energy policy.
Supreme Court Decision
On Wednesday, the Supreme Court ruled in favour of Michigan, determining that Enbridge Energy, the operator of Line 5, had delayed too long in its attempt to shift the case to federal court. Justice Sonia Sotomayor, writing for the court, stated that the case would continue to be adjudicated under state law, acknowledging Michigan’s right to address concerns about the pipeline’s safety and environmental impacts.
The litigation began when Michigan Attorney General Dana Nessel filed a lawsuit in June 2019, seeking to invalidate the easement that permits Enbridge to operate a 4.5-mile (6.4 km) section of the pipeline beneath the Straits of Mackinac, a crucial link between Lake Michigan and Lake Huron. In June 2020, a restraining order was issued by Ingham County Judge James Jamo, temporarily halting operations, although Enbridge was allowed to continue under certain safety protocols.
The Legal Battle
Enbridge’s attempts to transfer the case to federal jurisdiction were based on claims about the implications for US-Canadian trade. However, in June 2024, a panel from the Sixth US Circuit Court of Appeals ruled that Enbridge had overlooked a 30-day deadline to file for such a change, thus sending the matter back to state court.
Concerns surrounding Line 5 have intensified since revelations in 2017 that gaps in the pipeline’s protective coating had been known to Enbridge since 2014. An anchor strike in 2018 further escalated fears of a potential oil spill, prompting increased scrutiny from state authorities. In 2020, Michigan Governor Gretchen Whitmer’s administration moved to revoke the easement for the pipeline, a decision that Enbridge is currently contesting in federal court.
Environmental Concerns and Future Plans
The pipeline’s safety has been a focal point of contention. Following the revocation of the easement, Enbridge secured a federal ruling allowing the pipeline to continue operating. However, the Supreme Court’s rejection of Governor Whitmer’s appeal has left open questions about the relationship between federal oversight and state authority regarding Line 5’s safety.
Moreover, Enbridge has proposed constructing a protective tunnel to encase the pipeline beneath the Straits of Mackinac. While the Michigan Public Service Commission granted the necessary permits in 2023, environmental groups and local tribes have initiated litigation to challenge this decision. The state Supreme Court is currently deliberating over this case, which underscores the ongoing conflict between energy infrastructure and environmental stewardship.
Broader Implications
Line 5 is not only a point of contention in Michigan but also faces legal challenges in Wisconsin, where a federal judge ordered the shutdown of a segment of the pipeline crossing the Bad River Band of Lake Superior’s reservation. Enbridge is appealing this ruling while simultaneously working on a reroute project, which has faced opposition from both the Bad River Band and environmental advocates concerned about the ecological impact of construction activities.
Why it Matters
The Supreme Court’s ruling is a pivotal moment in the ongoing struggle between state and federal authorities over energy regulation and environmental safety. As climate change concerns mount, the outcome of this case may set a precedent for how energy infrastructure is managed in sensitive ecological areas. The implications extend beyond the immediate legal ramifications, influencing future energy policies and the balance between economic interests and environmental protection. The fate of Line 5 could very well shape the narrative around fossil fuel dependency and the urgent need for sustainable alternatives.
