§1446(b)(1)’s 30-Day Civil Removal Deadline Is Not Subject to Equitable Tolling

Introduction

Enbridge Energy, LP v. Nessel (608 U. S. ___ (2026)) arose from Michigan’s efforts to halt operation of Enbridge’s “Line 5” petroleum pipeline, including a four-mile segment crossing the Straits of Mackinac under a 1953 state easement. In 2019, Michigan’s Attorney General sued in state court to void the easement and declare continued operations unlawful. Enbridge was served on July 12, 2019, but did not remove within the 30-day deadline in 28 U. S. C. §1446(b)(1); instead, it litigated in state court.

After a separate 2020 lawsuit filed by the Governor was removed and litigated in federal court, Enbridge removed the Attorney General’s earlier-filed case on December 15, 2021—887 days after service. The federal district court excused the lateness on equitable grounds. The Sixth Circuit reversed, and the Supreme Court granted certiorari to resolve a circuit split on whether §1446(b)(1) is subject to equitable tolling.

Summary of the Opinion

The Court (Sotomayor, J., unanimous) affirmed the Sixth Circuit and held that §1446(b)(1)’s 30-day deadline for removal of a civil action is not subject to equitable tolling. Even assuming a presumption of equitable tolling could apply, the Court concluded that the statute’s text, structure, and context rebut tolling. Enbridge’s removal was therefore untimely, and remand to Michigan state court was required.

Analysis

Precedents Cited

1) Removal is purely statutory; timing rules are central to the statutory scheme

Syngenta Crop Protection, Inc. v. Henson, 537 U. S. 28 (2002): The Court anchored its analysis in the principle that removal “is entirely a creature of statute,” reinforcing that courts may not create extra-statutory pathways into federal court (including via open-ended equitable extensions) absent congressional authorization.
Grable & Sons Metal Products, Inc. v. Darue Engineering & Mfg., 545 U. S. 308 (2005): Used as background for why Enbridge believed federal-question jurisdiction existed in the Governor’s later suit (and later removed this case after winning that remand fight), illustrating that removal timing is distinct from the merits of whether federal jurisdiction exists.

2) Nonjurisdictional does not mean equitably extendable

McIntosh v. United States, 601 U. S. 330 (2024): Supported the proposition that the §1446(b)(1) deadline is nonjurisdictional because it does not speak in jurisdictional terms.
Boechler v. Commissioner, 596 U. S. 199 (2022): Provided the modern framework distinguishing jurisdictional rules (no equitable exceptions) from nonjurisdictional rules, while underscoring that nonjurisdictional deadlines may still be “mandatory.”
Nutraceutical Corp. v. Lambert, 586 U. S. 188 (2019): Supplied the key caution that the absence of jurisdictional status does not render a deadline “malleable in every respect,” and that some deadlines remain mandatory and not susceptible to equitable tolling.

3) The “presumption of equitable tolling” and how it can be rebutted

Lozano v. Montoya Alvarez, 572 U. S. 1 (2014): Cited for the limitation that the Court has typically applied the presumption of equitable tolling to statutes of limitations, foreshadowing the threshold debate whether §1446(b)(1) is even in that category.
Arellano v. McDonough, 598 U. S. 1 (2023): The Court’s principal template. It used Arellano’s “good reason to believe Congress did not want equitable tolling” standard and its methodology: looking to text, structure, and context, especially where Congress enumerates detailed exceptions that already reflect equitable judgments.
United States v. Brockamp, 519 U. S. 347 (1997): Supplied the structural inference that an explicit, detailed set of exceptions strongly signals Congress did not intend additional “open-ended” equitable exceptions.
United States v. Beggerly, 524 U. S. 38 (1998): Supported the idea that where Congress has already built an equity-sensitive mechanism into the statutory design (akin to a discovery rule), that tends to cut against further equitable tolling; also cited for concerns about a “cloud of uncertainty” where finality is important.
United States v. Kwai Fun Wong, 575 U. S. 402 (2015): Used to show that mandatory-sounding text alone does not end the analysis; structure and scheme can still rebut tolling even if language like “shall” can sometimes be tolled in other contexts.
Hallstrom v. Tillamook County, 493 U. S. 20 (1989): Reinforced that courts should not upset the “balance struck by Congress” when a statutory scheme reflects deliberate tradeoffs.
Holland v. Florida, 560 U. S. 631 (2010), and Young v. United States, 535 U. S. 43 (2002): Addressed Enbridge’s attempts to frame the rebuttal standard (“clearest command”) and to treat certain timing provisions as “accrual” rules rather than exceptions; the Court distinguished Holland’s habeas-specific context.

4) Efficiency/finality values in removal doctrine

BP p.l.c. v. Mayor and City Council of Baltimore, 593 U. S. 230 (2021): Cited for removal statutes’ “obvious concern with efficiency,” supporting a strict, early resolution of forum disputes.
Powerex Corp. v. Reliant Energy Services, Inc., 551 U. S. 224 (2007): Reinforced the “general interest in avoiding prolonged litigation on threshold nonmerits questions,” which would be undermined by late-removal litigation under equitable tolling.
Kircher v. Putnam Funds Trust, 547 U. S. 633 (2006): Used to emphasize that the removal/remand scheme intentionally prioritizes finality and efficiency (even at some cost to accuracy), consistent with restricting belated relitigation of forum.

5) Statutory-interpretation reinforcement

Bittner v. United States, 598 U. S. 85 (2023): Provided the interpretive canon that Congress’s inclusion of language in one part of a statutory landscape and omission in another indicates a meaningful difference—in this case, Congress expressly allowing “good cause” late filing for criminal removals but not for civil removals.
United States v. Detroit Timber & Lumber Co., 200 U. S. 321 (1906): Appeared in the syllabus note (about headnotes not being part of the opinion), not as a driver of the tolling holding.

6) Lower-court decisions framing the conflict and factual posture

Gillis v. Louisiana, 294 F. 3d 755 (CA5 2002), and Loftin v. Rush, 767 F. 2d 800 (CA11 1985): Identified as examples of circuits allowing equitable tolling of §1446(b)(1) in some circumstances, creating the split resolved by this case.
Enbridge Energy, LP v. Whitmer, 2025 WL 3707609 (WD Mich.): Noted in a footnote to show related federal litigation continued and that federal preemption questions existed on the merits—yet those merits did not relax the removal timing constraints.

Legal Reasoning

Step 1: §1446(b)(1) is nonjurisdictional—yet still may be mandatory. The Court accepted that §1446(b)(1) is not jurisdictional (consistent with McIntosh v. United States), but stressed (via Nutraceutical Corp. v. Lambert) that nonjurisdictional deadlines may still be non-tollable “mandatory” rules.
Step 2 (assumed): even if a presumption of equitable tolling applies, it is rebutted. Rather than definitively classify §1446(b)(1) as a statute of limitations, the Court assumed arguendo that a presumption could apply and held it was rebutted under Arellano v. McDonough.
Text: “shall be filed within 30 days” suggests strictness; not dispositive alone (cf. United States v. Kwai Fun Wong), but consistent with a mandatory reading.
Structure (decisive): Congress already built specific, equity-inflected exceptions into the removal system. The Court emphasized the detailed exception set within §1446 itself:
- §1446(b)(3) grants an additional 30 days when removability is later “ascertained,” operating much like a discovery-style extension (citing United States v. Beggerly).
- §1446(c)(1) then caps diversity removals under (b)(3) at one year, but creates an explicit “bad faith” exception—an express equitable safeguard that would be largely redundant if courts could toll §1446(b)(1) whenever fairness favored it.
Beyond §1446, Congress enacted narrow, express mechanisms to enlarge the §1446(b) timing rules “for cause shown” or with leave of court in particular contexts (e.g., §1441(d), §1454(b)(2), §1441(e)(1)). The Court treated these as powerful evidence Congress did not intend a general, judicially created equitable-tolling overlay for ordinary civil removals.
Context/purpose: efficiency, finality, and early resolution of forum. Removal statutes aim to resolve forum early; equitable tolling would cause uncertainty and waste by allowing a “late removal” cloud to hang over state-court litigation (citing BP p.l.c. v. Mayor and City Council of Baltimore, Powerex Corp. v. Reliant Energy Services, Inc., and Kircher v. Putnam Funds Trust).
Rejection of Enbridge’s “clearest command” framing. The Court rejected the claim that only a “clearest command” can rebut tolling, explaining that prior cases require only that Congress’s choice be evident from text, structure, and context (citing Arellano v. McDonough, United States v. Beggerly, and United States v. Brockamp). It confined Holland v. Florida’s “clearest command” phrasing to habeas’s distinctive equitable tradition.
Criminal removal comparison underscores deliberate omission for civil cases. Congress expressly authorized late filing “for good cause shown” in criminal removals (§1455(b)(1)), but did not create an analogous general provision for civil removals—supporting a negative inference (reinforced by Bittner v. United States).
Important limitation: The Court resolved only equitable tolling and expressly did not resolve the applicability of other equitable doctrines such as waiver, forfeiture, or estoppel.

Impact

Resolves a circuit split: By rejecting equitable tolling for §1446(b)(1), the Court disapproves the approach reflected in Gillis v. Louisiana and Loftin v. Rush, bringing national uniformity to civil removal timing.
Stronger forum certainty for plaintiffs after day 30: Once 30 days from service/receipt of the initial pleading elapse (absent statutory exceptions like §1446(b)(3)), plaintiffs can generally treat the forum as settled—reducing strategic uncertainty and duplicative litigation.
Incentivizes early jurisdictional assessment by defendants: Defendants must evaluate removal immediately. Waiting to test defenses in state court and removing only after a favorable federal ruling elsewhere—as Enbridge effectively did—now carries a clear, categorical timing risk.
Elevates the importance of statutory exceptions: Practice will likely shift toward (i) careful invocation of §1446(b)(3) “ascertainment” and (ii) in diversity, developing records on §1446(c)(1) “bad faith” rather than arguing generalized equitable tolling.
Limits equitable arguments in removal/remand litigation: Litigants should expect courts to treat statutory timing in removal with the same “specified-exceptions-only” logic the Court has applied in other contexts, emphasizing structural design over ad hoc fairness.

Complex Concepts Simplified

Removal: A statutory procedure allowing a defendant to move a case filed in state court into federal court when federal jurisdiction exists (e.g., federal-question jurisdiction under §1331 or diversity under §1332).
§1446(b)(1)’s 30-day clock: The default rule: a defendant must file a notice of removal within 30 days of receiving the initial pleading or being served with the summons (whichever is shorter).
Equitable tolling: A judge-made doctrine that can pause or extend certain filing deadlines for fairness (for example, if an extraordinary circumstance prevented timely filing). The Court held it does not apply to §1446(b)(1).
Nonjurisdictional vs. jurisdictional deadlines: Jurisdictional rules concern a court’s power and cannot be waived or equitably excused. Nonjurisdictional rules can sometimes be waived or forfeited, but they are not automatically extendable by equitable tolling.
“Ascertained” removability (§1446(b)(3)): A built-in statutory extension: if removability is not clear from the initial pleading but becomes clear later from certain papers, a new 30-day removal window opens from when removability can first be ascertained.
“Bad faith” exception (§1446(c)(1)): In diversity cases, even if removability is later ascertained, removal is generally barred after one year—unless the plaintiff acted in bad faith to prevent removal.

Conclusion

Enbridge Energy, LP v. Nessel establishes a clear rule: the 30-day civil removal deadline in §1446(b)(1) cannot be equitably tolled. The Court’s reasoning is structural and systemic: Congress created a detailed timing regime with specific, targeted exceptions (inside and outside §1446) and prioritized early, efficient, and final resolution of forum. The decision narrows defendants’ options after the 30-day window closes, channels disputes into the statute’s enumerated exceptions, and reduces the risk that litigants will relitigate forum deep into the life of a case.
