Fifth Circuit: Class-Action Tolling Ends Only on Unambiguous Exclusion
The Fifth Circuit on October 26, 2026 revived a former Union Pacific conductor's ADA suit, holding that a putative class member keeps American Pipe tolling unless a revised class definition unambiguously excludes him. The panel reversed a Rule 12(b)(6) dismissal and remanded.

Jurisdiction scope: This article addresses a federal appellate decision binding in the Fifth Circuit (Texas, Louisiana and Mississippi) on when American Pipe tolling of a federal employment discrimination deadline stops running for a putative class member. It does not address state law limitations periods, non-employment class actions, or whether the plaintiff's ADA claim has merit.
What Happened
James Bien worked as a locomotive train conductor for Union Pacific Railroad Company. In 2013, as part of his Federal Railroad Administration certification, he took an Ishihara color vision test and failed. He failed a follow-up color vision field test in July 2013.
Union Pacific removed him from the conductor job that same month. A letter told him he was restricted from work requiring color signal recognition, that the restriction could not be accommodated, and that his conductor employment was terminated. He failed another color vision field test in August 2013 and, in 2014, after several months of unemployment, Union Pacific hired him as a Manager of Crew Utilization at lower pay.
In September 2015, acting on a recertification notification, Bien took an Ishihara test and passed. He asked Union Pacific to administer the confirming field test, reconsider his work restriction, and reinstate him as a conductor.
Union Pacific refused in an October 2015 letter. According to the opinion, the letter said his request had been "formally reviewed by a committee that reviews all [field test] appeals," that his color vision deficiency was "presumed to be hereditary and permanent," and that the 2015 passing Ishihara test "does not negate or override the finding" of the failed 2013 field test. The opinion also records that the 2015 Ishihara test was "done in error": Union Pacific had administered it by mistake.
Bien dual-filed a charge of discrimination with the EEOC and the Texas Workforce Commission in April 2020. He received a right-to-sue letter and sued in January 2025 in the Eastern District of Texas, docket 4:25-CV-74.
The class action behind the tolling argument
Nearly nine years before Bien sued, in February 2016, a separate group of plaintiffs filed a class action against Union Pacific in the District of Nebraska, Harris v. Union Pacific Railroad Company, 329 F.R.D. 616 (D. Neb. 2019), reversed at 953 F.3d 1030 (8th Cir. 2020). The plaintiffs' original class definition covered:
"Individuals who were removed from service over their objection, and/or suffered another adverse employment action, during their employment with Union Pacific for reasons related to a Fitness-for-Duty evaluation at any time from 300 days before the earliest date that a named Plaintiff filed an administrative charge of discrimination to the resolution of this action." Source: Harris v. Union Pacific R.R. Co., 329 F.R.D. 616, 621 (D. Neb. 2019), as quoted in Bien v. Union Pacific R.R. Co., No. 26-40061, at 4 (5th Cir. Oct. 26, 2026)
In February 2019 the Harris court certified a narrower class:
"[a]ll individuals who have been or will be subject to a fitness-for-duty examination as a result of a reportable health event at any time from September 18, 2014 until the final resolution of this action." Source: Harris, 329 F.R.D. at 628, as quoted in Bien, No. 26-40061, at 4
The district court in Bien's case held he fell inside the first definition but outside the second, on the theory that Union Pacific's handling of his 2015 test was not a "fitness-for-duty examination" within the second definition's meaning. Because exclusion restarted his limitations clock, the court granted Rule 12(b)(6) dismissal and treated the exhaustion and failure-to-state-a-claim questions as moot.
The arithmetic sits in a footnote. The opinion states that the District of Nebraska certified the second definition on February 5, 2019, so if that ended tolling, Bien had 300 days, until December 2, 2019, to file his EEOC charge, and he did not file until April 2020 (Bien, No. 26-40061, at 4 n.2).
What the panel held
The panel disagreed with the district court on exclusion.
"Because excluding a class member from American Pipe tolling requires unambiguous exclusion, Union Pacific does not prevail. Its arguments, however elegant, are either insufficient to put exclusion beyond doubt or turn on the types of technical textual arguments that undermine the very purposes of American Pipe tolling." Source: Bien v. Union Pacific R.R. Co., No. 26-40061, at 2 (5th Cir. Oct. 26, 2026)
Judge Jerry E. Smith wrote for a panel of Judges Smith, Haynes and Engelhardt. The Fifth Circuit's opinions feed lists the document as a published opinion released October 26, 2026, and the filed version carries no concurrence or dissent.
Applying the standard, the panel said it would seem plausible on its face that the 2015 test subjected Bien to a fitness-for-duty examination within the second definition's meaning, and that the test having been given in error was not relevant to whether he was plausibly subjected to an examination (Bien, at 9). It noted that Union Pacific had Bien take a test bearing on the validity of his work restriction, then weighed the new result against his prior status before denying re-testing, which the panel said showed the episode did not unambiguously fail to subject him to a fitness-for-duty examination (Bien, at 9 to 10).
The disposition is narrow, and the panel said so.
"Accordingly, we REVERSE with regard to Bien's exclusion from the class and REMAND for further proceedings. We place no limitation on the matters that the district court, as appropriate, may address, and we express no view on what decisions it should announce." Source: Bien, No. 26-40061, at 12 to 13
The panel also declined to reach exhaustion of administrative remedies, noting that the district court had dismissed the question as moot, that Bien did not mention it in his opening brief, and that it received relatively minimal briefing. It remanded that issue for the district court to address (Bien, at 12). The panel did not rule on the ADA merits.

What the Law Actually Says
American Pipe tolling comes from American Pipe & Construction Co. v. Utah, 414 U.S. 538 (1974). The Supreme Court held that "the commencement of a class action suspends the applicable statute of limitations as to all asserted members of the class who would have been parties had the suit been permitted to continue as a class action" (414 U.S. at 554).
The rationale is equitable. Absent the rule, a person whose own deadline was near would have to choose between relying on the class and filing a protective individual suit, because the class might later be narrowed to exclude him after his own clock had run. The Bien panel restated that reasoning and cited American Pipe at 553 (Bien, at 5).
As the Fifth Circuit framed the doctrine, American Pipe tolling "applies from the moment a plaintiff satisfies even a putative class definition, and it pauses his claim's statute of limitations unless and until he is unambiguously excluded from a class definition," at which point limitations resumes running (Bien, at 6). The panel drew that unambiguous-exclusion standard from its own 2024 decision in Zaragoza v. Union Pacific Railroad, 112 F.4th 313 (5th Cir. 2024), cert. denied, 145 S. Ct. 1428 (2025), which also involved American Pipe tolling off the Harris class action, and it followed the reasoning of the Ninth Circuit's decision in DeFries v. Union Pacific Railroad, 104 F.4th 1091 (9th Cir. 2024).
The panel then put a floor under what counts as unambiguous.
"Nothing but the most straightforward, black-and-white, no-lawyer-required cases of exclusion will end American Pipe tolling for a plaintiff who meets an initial class definition. Conversely, a plaintiff who offers a plausible reading of the class definition that includes him will enjoy the benefit of American Pipe tolling." Source: Bien, No. 26-40061, at 7 to 8
A footnote makes the vantage point explicit: "In the American Pipe context, the inquiry is whether a plaintiff without counsel would understand that the class definition unambiguously excluded him" (Bien, at 7 n.7). The panel distinguished that question from the ambiguity analysis courts once performed under Chevron, U.S.A., Inc. v. Natural Resources Defense Council, 467 U.S. 837 (1984), which was overruled by Loper Bright Enterprises v. Raimondo, 603 U.S. 369 (2024).
Two mechanics matter for a reader trying to locate a situation in this doctrine.
First, a class definition is not fixed. Federal Rule of Civil Procedure 23(c)(1)(C) provides that "An order that grants or denies class certification may be altered or amended before final judgment." A revision of the definition is a different event from a denial of certification or a dismissal, and Bien turns on a revision.
Second, the clock in dispute was an administrative deadline, not a courthouse deadline. The ADA borrows Title VII's enforcement machinery: 42 U.S.C. 12117(a) makes "The powers, remedies, and procedures set forth in sections 2000e-4, 2000e-5, 2000e-6, 2000e-8, and 2000e-9 of this title" available to a person alleging disability discrimination in employment. Under 42 U.S.C. 2000e-5(e)(1), a charge must be filed within 180 days after the alleged unlawful employment practice occurred, extended to 300 days where the aggrieved person "has initially instituted proceedings with a State or local agency with authority to grant or seek relief from such practice." The same provision caps that extension: the charge must be filed within 300 days of the practice or within 30 days after notice that the state or local agency has terminated its proceedings, whichever is earlier.
The EEOC states the same rule in plain terms: "In general, you need to file a charge within 180 calendar days from the day the discrimination took place," and that deadline "is extended to 300 calendar days if a state or local agency enforces a law" prohibiting the same discrimination. Bien dual-filed with the Texas Workforce Commission, which is why the 300-day figure appears in the opinion's footnote.
A separate deadline follows the charge. Under 42 U.S.C. 2000e-5(f)(1), once the agency gives notice of the right to sue, "a civil action may be brought" within "ninety days after the giving of such notice." The opinion records that Bien received a right-to-sue letter and sued in January 2025, but the appeal concerned the charge-filing deadline, not the 90-day suit window.
Our state-by-state guide to statutes of limitations explains how civil filing clocks work generally, and the page on Texas filing deadlines by case type covers the state-law periods that run alongside federal employment deadlines. Federal employment deadlines of the kind at issue in Bien come from federal statute, not from Texas law.
Fights over what stops and restarts a clock are not confined to class actions. We have covered an Ohio Supreme Court ruling on how the saving statute applies when an action is refiled and a North Carolina decision tolling a judgment renewal deadline during a bankruptcy stay. Each turns on the question Bien asks: which event stops the clock, and which event starts it running again.

Analysis: Why This Matters
The following is analysis from the Recording Law Editorial Team.
The holding allocates the cost of an ambiguous class definition to the defendant rather than to the absent class member. The panel's stated reason is equitable, and it explains the equity in practical terms. A rule that ended tolling on any arguable narrowing would push putative class members to hire counsel to monitor class definitions, or to file protective individual suits the moment the wording shifted. The opinion applies that concern to the wording drift between the two Harris definitions, saying the shift "turns on the kinds of subtle distinctions in language that are fodder for lawyers and quicksand for laymen," quoting the Eighth Circuit's decision in DeGeer v. Union Pacific Railroad, 113 F.4th 1035, 1040 (8th Cir. 2024) (Bien, at 12).
What stands out is how little work a defendant's superior reading does under this standard. The panel credited Union Pacific with "elegant and persuasive arguments" and still found them insufficient, because the standard asks whether exclusion is beyond serious debate rather than which reading prevails (Bien, at 12). On that framing, a motion to dismiss resting on the end of class-action tolling succeeds only where exclusion is obvious from the definition itself.
The decision also sits inside an unusual procedural history that the panel flagged without resolving. It noted that Zaragoza declined to treat the Harris class as narrowed for tolling purposes in part because the certified class had itself been overruled as overbroad by the Eighth Circuit at Union Pacific's request, and that Zaragoza "suggested, though did not hold," that Union Pacific may be estopped from discarding its earlier position in order to argue a plaintiff falls outside the certified class (Bien, at 11 n.12). The panel did not decide that estoppel question.
Nothing in the opinion speaks to whether Bien's ADA claim is sound. The panel reversed a dismissal, remanded exhaustion for the district court, and wrote that it expresses "no view on what decisions it should announce" (Bien, at 12 to 13). This is a ruling about a gatekeeping defense, not about disability discrimination law.
How This Affects You
Within the Fifth Circuit, which covers Texas, Louisiana and Mississippi, Bien holds that a putative class member retains American Pipe tolling until a class definition unambiguously excludes him, and that a plausible reading placing him inside the definition is enough to preserve tolling at the pleading stage (Bien, at 7 to 8).
Courts have generally treated American Pipe tolling as protecting an individual claim while a class action is pending, so that an asserted class member need not file a separate suit to keep the claim alive. American Pipe itself concerned class members who sought to intervene (American Pipe, 414 U.S. at 554); the Supreme Court extended the rule to those who later file their own individual actions in Crown, Cork & Seal Co. v. Parker (1983) 462 U.S. 345. Bien addresses the narrower question of what ends that protection, and in the Fifth Circuit the answer is unambiguous exclusion rather than a plausible narrowing.
The type of event matters. A certification order altered or amended under Federal Rule of Civil Procedure 23(c)(1)(C) is not the same thing as certification being denied or a case being dismissed, and the standard the Fifth Circuit applied in Bien is addressed to a revised definition. If your circuit follows the same unambiguous-exclusion approach, the question a court would ask is whether a person without a lawyer reading the revised definition would see that it shut him out (Bien, at 7 n.7).
Because the deadline in Bien was an administrative charge deadline, the arithmetic for an ADA or Title VII claimant runs through 42 U.S.C. 2000e-5(e)(1) as incorporated by 42 U.S.C. 12117(a), and then through the 90-day suit window in 42 U.S.C. 2000e-5(f)(1). Those federal periods sit alongside, and are separate from, state-law employment doctrines such as the rules described on our Texas at-will employment page.
What Happens Next
The case returns to the Eastern District of Texas, docket 4:25-CV-74, once the mandate issues. The Fifth Circuit's docket entry for the opinion gives a mandate issue date of November 16, 2026. The panel remanded the exhaustion question for that court to address and stated that it placed no limitation on the matters the district court may take up (Bien, at 12 to 13).
The events that would change this posture are identifiable: a ruling on exhaustion, a renewed motion addressing failure to state a claim, a petition for panel rehearing or rehearing en banc, or a petition for certiorari. As of November 1, 2026 we have verified the filed opinion and its listing in the court's published-opinions feed, and we have not verified any post-opinion docket activity. The decision is not yet final: the mandate was docketed to issue on November 16, 2026, which falls seven days after the fourteen-day window for a petition for panel rehearing or rehearing en banc closes on November 9, 2026. A timely petition would delay the mandate.

Frequently Asked Questions
Did the Fifth Circuit decide that Union Pacific discriminated against James Bien?
No. The October 26, 2026 opinion in Bien v. Union Pacific Railroad Company, No. 26-40061, reversed a Rule 12(b)(6) dismissal on limitations grounds and remanded. The panel expressly declined to reach administrative exhaustion and expressed no view on the ADA merits.
What is American Pipe tolling?
It is the rule from American Pipe and Construction Co. v. Utah, 414 U.S. 538 (1974), that the commencement of a class action suspends the applicable statute of limitations for asserted class members who would have been parties had the suit continued as a class action. The Supreme Court stated that rule at page 554.
When does American Pipe tolling stop for a putative class member in the Fifth Circuit?
Under Bien, tolling continues unless and until a class definition unambiguously excludes the person, at which point limitations resumes running (Bien, No. 26-40061, at 6). The panel described the standard as reaching only straightforward, no-lawyer-required cases of exclusion.
Does a narrowed class definition automatically restart my limitations clock?
Not under the Fifth Circuit's approach in Bien. The panel held that a defendant's plausible, or even persuasive, reading of a narrowed definition is not enough, because exclusion must be beyond serious debate (Bien, at 7 to 8 and 12). Federal Rule of Civil Procedure 23(c)(1)(C) allows a certification order to be altered or amended before final judgment.
Which deadline was actually at issue in Bien?
An administrative charge deadline rather than a court filing deadline. The opinion states that if tolling ended when the narrower class was certified on February 5, 2019, Bien had 300 days, until December 2, 2019, to file his EEOC charge, and he filed in April 2020 (Bien, at 4 n.2).
How long is the deadline to file an EEOC charge on an ADA employment claim?
Under 42 U.S.C. 2000e-5(e)(1), incorporated into the ADA by 42 U.S.C. 12117(a), a charge must generally be filed within 180 days after the alleged unlawful employment practice occurred, extended to 300 days where the person first instituted proceedings with a state or local agency with authority over the practice, or within 30 days after notice that the state or local agency terminated its proceedings, whichever comes first. The EEOC states the same 180 and 300 day figures.
Is this decision binding outside Texas?
It binds federal courts in the Fifth Circuit, which covers Texas, Louisiana and Mississippi. The panel relied on its own earlier decision in Zaragoza v. Union Pacific Railroad, 112 F.4th 313 (5th Cir. 2024), and followed the reasoning of the Ninth Circuit in DeFries v. Union Pacific Railroad, 104 F.4th 1091 (9th Cir. 2024).
What was the Harris class action?
Harris v. Union Pacific Railroad Company was filed against Union Pacific in the District of Nebraska in February 2016. That court certified a narrower class in February 2019, reported at 329 F.R.D. 616, 628 (D. Neb. 2019), and as the Bien opinion recounts, the Eighth Circuit later overruled that class as overbroad, 953 F.3d 1030 (8th Cir. 2020).
Was there a dissent or concurrence?
No. Judge Jerry E. Smith wrote the opinion for a panel of Judges Smith, Haynes and Engelhardt, and the version filed October 26, 2026 contains no concurrence or dissent.
