*263In 2015, John Edward Clark was diagnosed with mesothelioma, a cancer caused by the inhalation of asbestos fibers. At that time, Mr. Clark was nearing completion of a Chapter 13 bankruptcy plan that he and his wife, Michele, had entered into in 2010. Although the Clarks fulfilled their last remaining obligations under the plan within a matter of weeks, their bankruptcy proceeding remained formally open for another full year before finally coming to a close on August 5, 2016. One week prior to their discharge from that proceeding, the Clarks initiated the present suit: a personal injury action against The Boeing Company and a host of other corporations they believed had exposed Mr. Clark to asbestos.
Boeing soon thereafter moved to dismiss the Clarks' personal injury suit on grounds of judicial estoppel. According to Boeing, the couple's failure to disclose Mr. Clark's diagnosis during bankruptcy bars them from pursuing personal injury claims related to that diagnosis now. The district court agreed, granting Boeing's motion and dismissing the Clarks' claims with prejudice.
Mr. Clark died during the pendency of the couple's appeal to this court. But we grant to Mrs. Clark what relief we can: the April 28, 2017 judgment of the district court granting Boeing's motion to dismiss is VACATED, and the case REMANDED for further proceedings.
I.
By early 2010, the Clarks found themselves more than $100,000 in debt.3 Seeking to regain their financial footing, the couple filed for Chapter 13 bankruptcy in the United States Bankruptcy Court for the District of Connecticut. Under the Clarks' proposed bankruptcy plan ("the Plan"), the couple agreed to repay their *264creditors in full, with interest at the federal judgment rate, over five years through monthly payroll deductions.4 See 28 U.S.C. § 1961. If all conditions were met, the Clarks would emerge from bankruptcy at the end of that period debt free. Following a confirmation hearing held in July 2010, the bankruptcy court set the Plan in motion.
For nearly five years, everything went as planned. Each month $2,152 was deducted from Mr. Clark's paycheck from his then employer, Boeing, and each month the couple inched closer to a discharge from bankruptcy. Then, only a few weeks before the Clarks' sixtieth (and final) monthly deduction was taken in July 2015,5 tragedy struck: Mr. Clark was diagnosed with mesothelioma.
Mr. Clark immediately suspected that the culprit was asbestos exposure, which he had suffered during his two decades of service in the United States Air Force and in his subsequent private sector employment. Soon after being diagnosed, Mr. Clark decided to bring suit against the corporations he believed responsible for exposing him to the known carcinogen. Mr. Clark-unsure of whether his bankruptcy asset schedules needed to be updated to reflect his diagnosis and intention to litigate-alerted his bankruptcy counsel to this information and "trusted him to do what was required under the law." Aff. of John Edward Clark ¶ 14 (Feb. 3, 2017). Mr. Clark's counsel, however, never passed this information along to the bankruptcy court during the pendency of the Clarks' bankruptcy proceeding.
On July 29, 2016, the Clarks filed a personal injury action in New York state court against more than fifty corporate defendants, including Boeing.6 One week later, with every creditor having been paid in full, the couple received a final discharge from bankruptcy.
After the Clarks' personal injury suit was removed to federal court,7 Boeing moved to dismiss. In its motion,8 Boeing argued that the suit was barred by the equitable doctrine of judicial estoppel, which "prevents a party from asserting a factual position in one legal proceeding that is contrary to a position that it successfully advanced in another proceeding." Rodal v. Anesthesia Grp. of Onondaga, P.C., 369 F.3d 113, 118 (2d Cir. 2004). According to Boeing, the couple's failure to disclose Mr. Clark's diagnosis during bankruptcy estops them from pursuing personal injury claims related to that diagnosis *265forever thereafter.9
The district court agreed. Characterizing judicial estoppel as a "harsh rule," it granted Boeing's motion on April 28, 2017, and dismissed this suit in its entirety. Clark v. Advanced Composites Grp. et al., 2017 WL 2266981, at *5 (S.D.N.Y. April 28, 2017). The Clarks timely appealed on May 26, 2017. Mr. Clark succumbed to his illness approximately six months later on November 24, 2017.
II.
There has been some uncertainty in this circuit as to the proper standard by which to review a district court's decision to invoke judicial estoppel. This uncertainty can be traced back to our decision in Uzdavines v. Weeks Marine Inc. , 418 F.3d 138 (2d Cir. 2005), where we indicated in passing that whether judicial estoppel applies "is a pure question of law, which we review de novo." Id. at 143 (emphasis removed). In subsequent decisions, we have taken pains to note that we are not bound by our dicta to this effect in Uzdavines .10 But because we were able to "affirm the district court under de novo review" in those cases, we declined to "consider whether a more deferential standard should apply." BPP Ill., LLC v. Royal Bank of Scot. Grp. LLC , 859 F.3d 188, 191 (2d Cir. 2017). It is time we put this uncertainty to rest: today we hold that a district court's invocation of judicial estoppel is reviewed only for abuse of discretion.
Abuse of discretion review is a "natural fit" for the judicial estoppel doctrine, which has a somewhat "amorphous nature." Alt. Sys. Concepts, Inc. v. Synopsys, Inc. , 374 F.3d 23, 31 (1st Cir. 2004). While the doctrine functions generally to bar litigants from taking inconsistent positions in successive suits, "the exact criteria for invoking judicial estoppel will vary based on specific factual contexts." Adelphia Recovery Tr. v. Goldman, Sachs & Co. , 748 F.3d 110, 116 (2d Cir. 2014) (internal quotation marks omitted). The district court is the "judicial actor ... better positioned" to determine whether the criteria for invoking judicial estoppel have been met within the particular factual context of a given case, Miller v. Fenton , 474 U.S. 104, 114, 106 S.Ct. 445, 88 L.Ed.2d 405 (1985), as well as whether a lesser sanction would suffice to address a litigant's lack of candor. See Klein v. Stahl GMBH & Co. Maschinefabrik , 185 F.3d 98, 109 (3d Cir. 1999) ("Judicial estoppel is [but] one arrow in the quiver of sanctions at a court's disposal.").
Nearly every other circuit has likewise held that abuse of discretion is the appropriate standard in this context.11 Even the *266one holdout-the Sixth Circuit-has recently "questioned the continuing viability" of de novo review in light of the Supreme Court's characterization of judicial estoppel as "an equitable remedy 'invoked by a court at its discretion.' " Javery v. Lucent Tech., Inc. , 741 F.3d 686, 697 (6th Cir. 2014) (internal citation omitted)).
While deferential, abuse of discretion review is not a rubber stamp. A district court may not "do inequity in the name of equity." 27A AM. JUR. 2D EQUITY § 84 (2012). And we will overturn a district court's decision to invoke judicial estoppel that, "though not necessarily the product of a legal error or a clearly erroneous factual finding[,] cannot be located within the range of permissible decisions." Zervos v. Verizon N.Y., Inc. , 252 F.3d 163, 169 (2d Cir. 2001).
III.
The question before us, then, is whether the district court abused its discretion in invoking judicial estoppel against the Clarks. We conclude that it did. We take it as axiomatic that judicial estoppel-an equitable doctrine-is to be construed in light of equitable principles. It seems equally evident to us that the balance of equities tips overwhelmingly in the Clarks' favor. And yet, the district court found judicial estoppel to be required. What went wrong?
The district court's April 28, 2017 judgment dismissing this suit started off on the right foot. It began by noting that the party asserting judicial estoppel must show (i) that "the party against whom the estoppel is asserted took an inconsistent position in a prior proceeding" and (ii) that "that position was adopted by the first tribunal in some manner, such as by rendering a favorable judgment." Clark , 2017 WL 2266981, at *4 (quoting Robinson v. Concentra Health Serv., Inc. , 781 F.3d 42, 45 (2d Cir. 2015) ). As to the first element, the district court held that the Clarks' failure to disclose their personal injury causes of action to the bankruptcy court amounted to an implicit false representation that no such causes of action existed. Id . As to the second element, the district court reasoned that the bankruptcy court "adopted" the Clarks' inconsistent position by "rendering a favorable judgment"-i.e., by discharging them from bankruptcy. Id .
Having satisfied itself that the Clarks met the judicial estoppel doctrine's two prerequisite elements, the district court held ipso facto that the couple's personal injury claims must be estopped. And therein lies the district court's error: judicial estoppel is not a mechanical rule. See Holmberg v. Armbrecht , 327 U.S. 392, 396, 66 S.Ct. 582, 90 L.Ed. 743 (1946) ("Equity eschews mechanical rules.").
That a litigant (i) took a prior inconsistent position and (ii) convinced an earlier tribunal to adopt that position may be necessary conditions for judicial estoppel to be imposed, but they are not sufficient ones. Before judicially estopping a litigant, a court must inquire into whether the particular factual circumstances of a case "tip the balance of equities in favor"
*267of doing so. New Hampshire v. Maine , 532 U.S. 742, 751, 121 S.Ct. 1808, 149 L.Ed.2d 968 (2001).
Our cases make clear that this inquiry begins by asking whether the prior inconsistent position in question gave the party to be estopped an "unfair advantage" over the party seeking estoppel. BPP Ill. , 859 F.3d at 192. The answer here is that Boeing concedes that it was in no way prejudiced by the Clarks' failure to disclose their personal injury causes of action to the bankruptcy court.
While significant, this concession does not end the inquiry. See, e.g. , Adelphia , 748 F.3d at 116 ("Although we have recognized that typically the application of judicial estoppel requires showing unfair advantage against the party seeking estoppel, we have not required this element in all circumstances." (internal quotation marks and brackets omitted)). We have been particularly apt to overlook the general requirement that a party seeking estoppel have suffered prejudice where, as here, the party to be estopped failed to make the proper disclosures during bankruptcy.12 In such circumstances, this court has justified the imposition of judicial estoppel in part on the unfair advantage the estopped party may have gained over "former creditors, who had a right to consider the [undisclosed] claims" during bankruptcy. BPP Ill. , 859 F.3d at 194.
As we have previously noted, however, this rationale cannot extend to the "unusual case" in which a debtor's nondisclosure had at most a "de minimis effect" on a prior bankruptcy proceeding. Adelphia , 748 F.3d at 120. This is just such a case. As the Standing Trustee for the District of Connecticut certified in an affidavit submitted on the Clarks' behalf, disclosure "would not have altered the outcome" of the couple's bankruptcy proceeding. Aff. of Molly T. Whiton ¶ 5 (Mar. 20, 2017).
This is because the Plan already required the Clarks to repay their creditors in full. Disclosing Mr. Clark's diagnosis to the bankruptcy court would therefore have only affected the couple's bankruptcy proceeding if their creditors were able to convince the bankruptcy court to raise the applicable interest rate under the Plan. Given that the Clarks were mere weeks away from completing repayment at the time of Mr. Clark's diagnosis, and were already paying interest at a standard rate, this scenario strikes us as more than implausible.13
Boeing does not seriously dispute any of these facts.14 Instead, it urges that, because "judicial estoppel protects the sanctity of the oath and the integrity of the judicial process," there are cases in which a court may properly invoke the doctrine even in response to a prior inconsistent position that had only a de minimis effect.
*268Bates v. Long Island R.R. Co., 997 F.2d 1028, 1037 (2d Cir. 1993). The point is well taken. We do not deny that there may be unusual circumstances in which the need to safeguard the integrity of the courts may tip the equities in favor of judicial estoppel even when the inconsistency in question made no material difference.
But this case is surely not of that sort. Nothing in the record before us suggests that the Clarks withheld Mr. Clark's diagnosis from the bankruptcy court in an effort to game the bankruptcy system. Indeed, it is hard to see what benefit they could even have hoped to obtain from nondisclosure. In these circumstances, we hold that the principles of equity require the courts to entertain Mrs. Clark's personal injury claims.
To be clear, we are not giving unscrupulous litigants the green light to play "fast and loose with the courts." Wight v. BankAmerica Corp ., 219 F.3d 79, 89 (2d Cir. 2000). Nor do we wish to hamper district courts who deem judicial estoppel necessary to ensure the "full disclosure by debtors" that is "essential to the proper functioning of the bankruptcy system." Chartschlaa v. Nationwide Mut. Ins. Co., 538 F.3d 116, 122 (2d Cir. 2008). But to hold on the facts of this case that Mrs. Clark's claims are barred by an equitable doctrine would be to deprive the concept of equity of any meaning. The district court's April 28, 2017 judgment granting Boeing's motion to dismiss is VACATED , and the case REMANDED for further proceedings.15
