Judicial estoppel is an equitable doctrine that generally prevents a party from assuming inconsistent positions in successive litigation, thereby protecting the integrity of the judicial process. New Hampshire v. Maine, 532 U.S. 742, 749–751 (2001). The aim of the doctrine is to “protect the integrity of the judicial process.” Id.
For years, the doctrine was applied in the context of debtors who failed to disclose claims in their bankruptcy. A debtor in bankruptcy must disclose his assets to facilitate an accurate estate, including claims against third parties, whether the debtor has filed a lawsuit or made a demand for payment, and must swear under penalty of perjury that the disclosures are true and correct. For a Chapter 13 debtor, the estate includes claims acquired after the case commences but before it is closed. 11 U.S.C. § 1306(a)(1). Courts applied judicial estoppel to bar a later lawsuit on an undisclosed claim.
In determining whether to apply judicial estoppel, several circuits—including the Fifth Circuit—had looked for the presence of the following criteria: “(1) the party against whom judicial estoppel is sought has asserted a legal position which is plainly inconsistent with a prior position; (2) a court accepted the prior position; and (3) the party did not act inadvertently.” Love v. Tyson Foods, Inc., 677 F.3d 258, 261 (5th Cir. 2012), abrogated by Keathley v. Buddy Ayers Constr., Inc., 146 S. Ct. 1532 (2026). The Fifth Circuit had held that “[j]udicial estoppel [was] particularly appropriate where … a party fails to disclose an asset to a bankruptcy court, but then pursues a claim in a separate tribunal based on that undisclosed asset.” Id. at 261-262, reasoning that debtors had a motivation to conceal claims where they stood to “reap a windfall had they been able to recover on the undisclosed claim without having disclosed it to the creditors.” Id. at 262. In evaluating “inadvertence,” the Fifth Circuit precedent held that an omission is inadvertent or mistaken only if (a) the debtor did not know the facts underlying the claim, or (b) there was no potential motive to conceal it.
That framework is no longer good law.
In Keathley, a unanimous Supreme Court held that, to decide whether a debtor’s failure to disclose a claim in bankruptcy was “inadvertent or mistaken” for purposes of judicial estoppel, courts must look to the totality of the circumstances surrounding the omission. The Court rejected the Fifth Circuit’s rule, which confined the inquiry to two circumstances: (1) whether the debtor knew the facts underlying the claim, and (2) whether the debtor had a potential motive to conceal it. The Court found that rule both too rigid and too broad.
A debtor and his wife filed a Chapter 13 petition; the bankruptcy court confirmed an amended plan providing for interest-free repayment of 100% of creditors’ claims over five years. While the bankruptcy remained open, the debtor was injured in a car accident. He retained a personal-injury attorney, and they filed a negligence suit without notifying the bankruptcy court of the debtor’s suit or claims. When the alleged tortfeasor moved for summary judgment on judicial estoppel grounds, the debtor immediately amended his schedule and submitted affidavits in support of his position: one from himself, attesting that he “believed [he] had done everything [he] needed to do,” and one from his bankruptcy counsel stating that the debtor “received no benefit monetarily, or otherwise, from the nondisclosure.”
The district court, applying Fifth Circuit precedent, entered summary judgment for the alleged tortfeasor based on a finding that the debtor knew the underlying facts and had a hypothetical motive to conceal. The Fifth Circuit affirmed per curiam. Judge Haynes concurred because circuit precedent dictated the result but expressed doubt that judicial estoppel’s goals were served given evidence that the omission was an “honest mistake,” and observed that other circuits take a more holistic approach. The Court granted certiorari to resolve a conflict: the Fifth and Tenth Circuits limit the inquiry to knowledge and motive, while five other circuits conduct a more fact-specific analysis.
Assuming without deciding that judicial estoppel can apply in the bankruptcy context and that inadvertence or mistake can serve as an exception, the Court held the Fifth Circuit’s rule “simultaneously too rigid and too broad.” The rigidity flows from a failure to treat judicial estoppel as the equitable doctrine it is. Equity “eschews mechanical rules; it depends on flexibility,” Holmberg v. Armbrecht, 327 U.S. 392, 396 (1946), and an equitable inquiry proceeds “on a case-by-case basis,” considering all relevant facts and circumstances, Holland v. Florida, 560 U.S. 631, 649–650 (2010). By allowing courts to weigh only two circumstances and no other evidence tending to show inadvertence, the Fifth Circuit’s rule was out of step with equity. The rule was also overly broad: because a debtor is rarely unaware of the facts underlying his own claim and will almost always hypothetically benefit from nondisclosure, the test treats nearly every omission as purposeful. In effect, it amounts to a “near-dispositive criterion” that fails to fairly inquire whether an omission resulted from true inadvertence or mistake. The Court framed its decision as “straightforward” and expressly narrow, declining to resolve whether bad faith is required for judicial estoppel to apply. It vacated and remanded for the Fifth Circuit to examine the totality of the circumstances surrounding the debtor’s failure to disclose.
The judgment was unanimous, but two concurrences suggest the doctrine’s future is far from settled. Justice Thomas, joined by Justice Gorsuch, questioned the foundation of judicial estoppel itself. In his view, it appears to lack any basis in statute, the Federal Rules, or the traditional inherent or equitable power of the federal courts, and he would have the Court reexamine it in a future case. Justice Sotomayor wrote separately. In her view, it may never make sense to apply judicial estoppel while a bankruptcy remains open. Doing so typically harms the very creditors the doctrine is meant to protect and hands a windfall to the defendant, a stranger to the bankruptcy, even though a bankruptcy court has ample tools of its own to address a belated disclosure, among them sanctions, plan modification, denial of discharge, and conversion to Chapter 7. In any context, she added, the doctrine should turn on the totality of the circumstances.
For practitioners, Keathley narrows the nondisclosure-based judicial estoppel defense, particularly in the Fifth and Tenth Circuits. A defendant can no longer expect summary judgment simply by showing that the debtor knew the facts and had a theoretical motive to conceal; courts must now weigh the full context of the omission, including corrective steps such as prompt amendment of the schedules and evidence that the debtor derived no benefit. Debtors and their counsel should still disclose potential claims promptly and, where an omission has occurred, develop a factual record of inadvertence, both to defeat judicial estoppel and to blunt the other tools a bankruptcy court can bring to bear on a belated disclosure. The Thomas and Sotomayor concurrences also suggest that judicial estoppel’s availability in bankruptcy, especially while a case is still open, may itself be vulnerable in future litigation.
