Enbridge Energy, LP v. Nessel
The Supreme Court unanimously ruled that Enbridge, a pipeline company, could not use a legal safety valve called equitable tolling to excuse its 887-day delay in moving Michigan's state-court lawsuit to federal court, far beyond the 30-day window federal law allows.
The decision settles a split among federal appeals courts by firmly establishing that the 30-day removal deadline is fixed — once it passes, the case stays in state court, and no judge can stretch the deadline on case-by-case fairness grounds.
How it got here: The district court allowed Enbridge's late removal on equitable grounds; the Sixth Circuit reversed and ordered the case sent back to state court; the Supreme Court took the case to resolve a split among federal appeals courts.
The Case in Depth
What happened
Enbridge owns and operates Line 5, a 645-mile petroleum pipeline that crosses Michigan's Straits of Mackinac under a 1953 easement from the State. In June 2019, Michigan's Attorney General sued in state court to have the easement declared void and the pipeline's operation declared unlawful, citing the risk of an oil spill. Federal law gives defendants 30 days to move such a case to federal court. Enbridge did not act within that window and instead litigated in state court for months, then waited 887 days total before attempting to move the case to federal court.
The question before the Court
Can a company that misses the 30-day deadline to move a lawsuit from state court to federal court ask a judge to excuse the delay on fairness grounds — even waiting nearly 900 days?
The Court's answer
No — Enbridge could not invoke equitable tolling (a legal safety valve courts sometimes use to excuse missed deadlines) to justify waiting 887 days to move the Michigan Attorney General's lawsuit from state court to federal court. The 30-day removal deadline cannot be extended by a judge on fairness grounds because Congress already built specific, targeted exceptions into the removal statutes and added explicit extension authority for defined categories of cases — a structure that would be pointless and redundant if a general equitable escape hatch were already available across all civil cases.
The Court did not need to decide whether the 30-day deadline technically qualifies as a "statute of limitations," because even if the usual presumption favoring tolling applied, the statute's text, structure, and surrounding context gave good reason to conclude Congress did not want judges extending this deadline on a case-by-case basis. The Court left open whether other equitable doctrines — such as waiver or estoppel — might separately apply to removal deadlines.

Why it matters
Companies and individuals sued in state court now have a clear, hard 30-day window to decide whether to move the case to federal court. No judge can extend it based on the circumstances. Plaintiffs who choose state court can be confident their forum choice is locked in once 30 days pass, preventing defendants from dragging them into federal court months or years later.
What changes now
The case returns to Michigan state court, where the Attorney General's lawsuit over Line 5's operation will resume. The Supreme Court's ruling is final on the legal question and is now binding on all federal courts: the 30-day civil removal deadline cannot be extended by equitable tolling. The underlying dispute over whether Enbridge may continue operating Line 5 involves separate federal litigation that remains ongoing.
What this does not decide
The Court expressly limits its holding to equitable tolling and leaves open whether other equitable doctrines — waiver, forfeiture, and estoppel — might still affect a removal deadline in some circumstances. The ruling says nothing about the merits of Michigan's claims against the pipeline or the validity of the 1953 easement.

How the Court got there
The legal reasoning, step by step
- The threshold question was whether §1446(b)(1)'s 30-day removal deadline is 'jurisdictional' — a category of rules that courts must enforce absolutely, cannot be waived, and admit no equitable exceptions. Everyone agreed it is not jurisdictional, since the statute does not use jurisdictional language. But being non-jurisdictional doesn't automatically make a deadline flexible; some non-jurisdictional deadlines are still mandatory and not open to equitable extension.
- Even assuming the 30-day deadline carries a presumption of equitable tolling (the presumption that courts have usually applied to statutes of limitations), that presumption can be rebutted when there is 'good reason to believe that Congress did not want the equitable tolling doctrine to apply.' The Court examined §1446(b)(1)'s text, structure, and context to see whether such good reason existed.
- The text speaks in strict mandatory terms — a notice of removal 'shall be filed within 30 days' — which, while not decisive on its own, is at least consistent with treating the deadline as fixed.
- More decisively, §1446 already contains specific exceptions that reflect equitable concerns: §1446(b)(3) gives defendants extra time when they only later discover a case is removable (functioning like a discovery rule), and §1446(c)(1) adds a 'bad faith' exception for diversity cases. When Congress carefully builds in targeted equitable safety valves, the strong inference is that it did not also intend an open-ended general tolling escape hatch on top of them.
- Provisions outside §1446 reinforce this inference. Congress expressly allowed time extensions 'for cause shown' for suits against foreign states, certain intellectual-property cases, and mass-accident cases — provisions that would be unnecessary if equitable tolling were already broadly available. Critically, Congress gave federal courts a general power to allow late removal in criminal cases but did not grant the same power in civil cases, and courts ordinarily treat that kind of deliberate omission as meaningful.
- The removal statutes reflect a strong policy interest in resolving forum questions quickly and finally. Allowing equitable tolling would leave plaintiffs uncertain for years whether their chosen state-court forum is secure, generating wasted effort in one court before a possible late transfer to another — precisely the prolonged threshold litigation Congress designed the removal scheme to prevent.
