- Decision released Apr 22, 2026
- What it's about
Michigan sued Enbridge in state court to stop operation of its Line 5 pipeline, but Enbridge did not try to move the case to federal court until long after the 30-day removal deadline had passed. The Supreme Court held that federal district courts cannot excuse or equitably toll that deadline, so the case had to remain in Michigan state court.
Question presented
Do district courts have the authority to excuse the thirty-day procedural time limit for removal in 28 U.S.C. § 1446(b)(1)?

Briefing
What it's about
Michigan sued Enbridge in state court over its Line 5 pipeline, but Enbridge tried to move the case to federal court after the 30-day deadline had passed. The Supreme Court said federal district courts cannot excuse or equitably toll that deadline, so the case stays in Michigan state court.
Vote
Impact
The ruling makes the 30-day deadline for moving a case from state court to federal court firm. Companies, governments, and other litigants that miss that window cannot ask a district judge to forgive the delay.
What's next
Michigan's lawsuit against Enbridge will continue in Michigan state court rather than federal court. Lower courts must apply the 30-day removal deadline as a hard limit, and parties must act within that window or lose the chance to remove.
What was the main fight in the Enbridge case?
The dispute was whether a federal district court can forgive a late attempt to move a case from state court to federal court. The Court said it cannot.
What real-world effect does this ruling have for companies and states?
It gives both sides a clear deadline and reduces late forum fights over where a case will be heard. A company that waits too long cannot switch courts later.
What happens next in this case after the Supreme Court's decision?
Michigan's case over Line 5 goes forward in Michigan state court. Enbridge cannot rely on a district court to overlook its missed federal removal deadline.
Decision
What the Court decided
If a party misses the 30-day deadline to remove a case to federal court, the case remains in state court.
Impact
This affects defendants and plaintiffs in civil lawsuits, including businesses and states. A defendant must seek removal (moving a case from state to federal court) within 30 days. For example, Enbridge’s late filing meant Michigan’s Line 5 lawsuit stayed in Michigan state court. Next, parties will need to decide early where they want to litigate. The ruling favors efficiency and finality, reducing the risk of wasted time and money.
