- 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 to shut down 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 that deadline, so the case stays in Michigan state court.
Vote
Impact
The decision makes the removal deadline a firm limit for parties that want to shift a case from state court to federal court. For example, a company that waits too long cannot ask a district judge to forgive the delay and keep the case in federal court.
What's next
The Line 5 fight now continues in Michigan state court, because federal court is no longer available through late removal. Lower courts will have to apply the Supreme Court's rule by treating the 30-day deadline as fixed, not flexible.
What was the core dispute in the Enbridge v. Nessel case?
The case asked whether a federal district court can forgive a late notice of removal after the 30-day deadline in federal law. The Court said no.
What are the real-world consequences of this decision for companies and states?
Parties must act quickly if they want federal court. States and other plaintiffs can keep cases in state court when the other side misses the deadline.
What happens next in the Line 5 litigation after the Supreme Court's decision?
The case returns to Michigan state court for the underlying dispute over Line 5. Enbridge cannot rely on late removal to move this lawsuit into federal court.
Decision
What the Court decided
If a party misses the 30-day deadline to remove a case, a federal district court cannot waive that deadline.
Impact
This affects people and companies sued in state court, including parties in Michigan’s Line 5 case. If a defendant misses the 30-day removal deadline, judges cannot forgive the delay for fairness reasons. For example, Enbridge filed late, so its lawsuit stayed in Michigan state court. Next, parties will need to decide quickly where to fight, because late switches waste time and money. The ruling also means courts cannot use equitable tolling (forgiving a missed deadline after extraordinary hurdles) here.
