Moreau v. White: Hague Return Orders Cannot Command Foreign Courts, and Judicial Estoppel Is Not an Extra-Treaty Bar to Mandatory Return

I. Introduction

Parties: Sarah S.C. Moreau (petitioner/left-behind parent; Plaintiff—Appellee) and Andrew Christopher White (respondent; Defendant—Appellant). After years of parallel custody litigation in Texas and Canada, Moreau filed a federal petition under the Hague Convention on the Civil Aspects of International Child Abduction alleging White wrongfully retained their two children in Texas in breach of her Canadian custody rights.

Core issues on appeal: (1) whether the children were habitually resident in Canada at the time of retention; (2) whether Moreau possessed and was exercising custody rights under Canadian law such that the retention was “wrongful”; (3) whether the Article 13(a) consent defense applied; (4) whether judicial estoppel could bar return as an extra-treaty defense; and (5) whether the district court could enjoin Texas proceedings and direct Canadian courts to decide custody.

Disposition: The Fifth Circuit affirmed the order returning the children to Canada but vacated the preliminary injunction, including the portion directing Canadian courts to adjudicate custody and the corollary restraint on Texas litigation.

II. Summary of the Opinion

  • Return affirmed: The court upheld the district court’s finding (clear-error review) that the children were habitually resident in Canada and that White’s retention in Texas was wrongful because it breached Moreau’s rights of custody recognized in Canada (including the right to determine the children’s place of residence).
  • Consent defense rejected: The court held White failed to prove that Moreau subjectively intended to consent to Texas’s final custody adjudication; repeated jurisdictional challenges and attempts to transfer/dismiss undermined the defense.
  • Judicial estoppel rejected as an extra-treaty defense: The court declined to use judicial estoppel to defeat the Convention’s mandatory return remedy, emphasizing the Convention’s text and the need for uniform international interpretation.
  • Injunction vacated on comity grounds: The district court’s “command language” directing Canadian courts to decide custody improperly affronted international comity; because the Texas injunction served to enforce that improper directive, it too was vacated.

III. Analysis

A. Precedents Cited and Their Role

1) Habitual residence: totality of the circumstances; no categorical rules

  • Monasky v. Taglieri, 589 U.S. 68 (2020): The foundation for the Fifth Circuit’s refusal to adopt White’s proposed categorical rule (i.e., that a court-authorized “temporary” move cannot ripen into a new habitual residence unilaterally). The panel repeatedly invoked Monasky’s directive that there are “no categorical requirements” and that habitual residence is a fact-driven, common-sense inquiry.
  • Smith v. Smith, 976 F.3d 558 (5th Cir. 2020): Supplied the Fifth Circuit’s articulation of habitual residence as a mixed question and the clear error standard of review for the district court’s fact-intensive determination.
  • Harm v. Lake-Harm, 16 F.4th 450 (5th Cir. 2021): Provided the “two permissible views of the evidence” clear-error principle; even if the panel might have weighed facts differently, it could not reverse absent clear error.
  • Baz v. Patterson, 100 F.4th 854 (7th Cir. 2024): Persuasive authority reinforcing Monasky’s anti-categorical approach, cited to reject the idea that a state court’s habitual-residence determination can be dispositive in Hague proceedings.
  • Guevara v. Castro, 155 F.4th 353 (5th Cir. 2025): Used to frame the Convention’s twin aims—restoring the status quo and deterring forum shopping— and to situate the case’s unusual procedural “chaos” within those goals.

2) Wrongful retention framework and custody-rights analysis

  • Delgado v. Osuna, 837 F.3d 571 (5th Cir. 2016): Supplied the three-element test for wrongful retention: (1) retention outside habitual residence; (2) breach of custody rights under habitual-residence law; (3) exercise of those rights.
  • Kovac v. Wray, 109 F.4th 331 (5th Cir. 2024): Supported the appellate principle that the court may affirm on any ground supported by the record, enabling the panel to avoid unnecessary pronouncements on Canadian statutory law by relying instead on the Canadian court’s recognition/supersession of the Texas order as the operative source of Moreau’s custody right to determine residence.
  • Abbott v. Abbott, 5 60 U.S. 1 (2010): Cited for treaty-interpretation methodology and for the Convention’s function of preventing a parent from selecting the custody forum by unilateral relocation in violation of custody rights. The panel used Abbott to reject White’s rhetorical inversion portraying the petitioner as the wrongdoer.

3) Consent defense: subjective intent and tribunal-specific consent

  • Larbie v. Larbie, 690 F.3d 295 (5th Cir. 2012), abrogated on other grounds by, Smith v. Smith, 976 F.3d at 561: The central Fifth Circuit authority for Article 13(a) consent, emphasizing the petitioner’s subjective intent and recognizing that consent for a particular tribunal to make a final custody determination can suffice. The panel distinguished Larbie on its record: unlike the mother in Larbie, Moreau repeatedly contested Texas as the final forum.
  • England v. England, 234 F.3d 268 (5th Cir. 2000): Quoted for the proposition that even when a defense applies, a district court retains discretion to order return, but that discretion must be tethered to Convention aims.
  • Gonzalez-Caballero v. Mena, 251 F.3d 789 (9th Cir. 2001) and Elkhaiat v. Mawashi, No. CV-24-02800, 2025 WL 711949 (D. Ariz. Mar. 5, 2025): Cited to illustrate disputed approaches to whether and how “revocation” of consent operates. The Fifth Circuit did not announce a broad revocation doctrine, but treated Moreau’s repeated attempts to dismiss/transfer as undercutting proof of subjective consent.

4) Extra-treaty equitable defenses (judicial estoppel) and treaty text

  • Lozano v. Montoya Alvarez, 572 U.S. 1 (2014): A key structural anchor for the court’s refusal to “export” U.S. background equitable principles into treaty interpretation. The panel analogized Lozano’s rejection of equitable tolling to its skepticism of extra-textual defenses to return.
  • Karpenko v. Leendertz, 619 F.3d 259 (3d Cir. 2010); Katona v. Kovacs, 148 F. App'x 158 (4th Cir. 2005); Stead v. Menduno, 77 F. Supp. 3d 1029 (D. Colo. 2014): Cited for the view that equitable defenses like unclean hands/equitable estoppel are generally not contemplated by the Convention and risk undermining its goals.
  • In re Prevot, 59 F.3d 556 (6th Cir. 1995) and Journe v. Journe, 911 F. Supp. 43 (D.P.R. 1995): Acknowledged to show the lack of uniformity—some courts have employed inherent-power doctrines in Hague-adjacent ways—but the panel declined to extend that line to judicial estoppel as a return-blocking defense here.
  • Whiting v. Krassner, 391 F.3d 540 (3d Cir. 2004) and Hamprecht v. Hamprecht, No. 12-cv-125, 2012 WL 12905608 (M.D. Fla. Apr. 19, 2012): The only judicial-estoppel Hague cases the panel located; neither supported using judicial estoppel to defeat mandatory return.
  • Holder v. Holder, 305 F.3d 854 (9th Cir. 2002): Used to confront the “windfall” critique (two bites at custody), emphasizing that “two opportunities” arise only when the Convention properly identifies a wrongful abduction/retention requiring return.
  • In re Superior Crewboats, Inc., 374 F.3d 330 (5th Cir. 2004): Provided the abuse-of-discretion standard for judicial estoppel rulings, though the panel’s holding ultimately rested on treaty-structure limitations rather than a granular estoppel-factor analysis.

5) Injunctions, international comity, and limits on commanding foreign courts

  • Karaha Bodas Co. v. Perusahaan Pertambangan Minyak Dan Gas Bumi Negara, 335 F.3d 357 (5th Cir. 2003): The central Fifth Circuit authority on balancing domestic interests and international comity when considering restraints affecting foreign proceedings.
  • Can. Filters (Harwich) Ltd. v. Lear-Siegler, Inc., 412 F.2d 577 (1st Cir. 1969): Invoked for the principle that the policy behind the Anti-Injunction Act should, “a fortiori,” counsel restraint before interfering with foreign courts.
  • Danaipour v. McLarey, 286 F.3d 1 (1st Cir. 2002): Cited as an example of a federal court lacking authority to order foreign-court action in aid of custody adjudication—supporting vacatur of the “command” to Canada.
  • Rodriguez v. Yanez, 817 F.3d 466 (5th Cir. 2016); Sealed Appellant v. Sealed Appellee, 394 F.3d 338 (5th Cir. 2004); Monasky v. Taglieri, 589 U.S. at 72; Harm v. Lake-Harm, 16 F.4th at 451: Cited to underscore that Hague proceedings fix the custody forum by reference to habitual residence and that non-habitual-residence jurisdictions should not adjudicate custody merits— but the panel emphasized those principles do not authorize federal courts to command foreign tribunals or to micromanage state-court jurisdictional determinations via injunction.
  • Levin v. Com. Energy, Inc., 560 U.S. 413 (2010): Cited for general comity/respect for state functions—used to reinforce the court’s view that Texas courts can assess their own jurisdiction post-return order.

B. Legal Reasoning

1) Habitual residence: rejecting formalism in favor of lived reality

The court treated habitual residence as a practical question: where were the children “at home” at the time of retention? The panel emphasized acclimatization facts the district court found persuasive—years living and schooling in Canada, relationships, extracurriculars, medical providers, and the children’s young-life proportion spent there—while acknowledging countervailing evidence (Moreau’s repeated “temporary” representations, and ties to Texas). Under clear-error review, the existence of competing inferences was dispositive: the appellate court would not reweigh.

The most “precedent-making” move here is not the result but the refusal to create a categorical rule that a court-authorized temporary move cannot become habitual residence absent bilateral parental intent. The panel located that argument outside Monasky’s framework and declined it.

2) Custody rights: affirming without broad pronouncements on foreign statutes

While the district court relied on Canadian statutes, the Fifth Circuit narrowed the path: even if statutory custody rights were contested, Moreau had rights of custody because the Canadian court recognized and superseded the Texas order in a way that preserved for Moreau, in Canada, the right to determine the children’s primary residence without the Texas geographic restriction. Since Hague “custody rights” include the right to determine residence (Article 5(a)), retaining the children in Texas breached that right.

3) Consent defense: subjective intent, not procedural exhaustion

Applying Larbie’s subjective-intent focus, the panel read Moreau’s litigation behavior as inconsistent and opportunistic but not as consent to Texas as the final tribunal. Critically, the court refused a rule that a parent must object to jurisdiction “ad nauseum” (or risk contempt by nonparticipation) to avoid being deemed to have consented. It treated Moreau’s repeated transfer/dismissal efforts as negating White’s proof burden on Article 13(a) consent.

4) Judicial estoppel: treaty text, uniformity, and reluctance to import domestic equity

The panel’s central move was structural: the Convention’s return command applies unless a Convention exception is proven, and the Supreme Court’s admonition in Lozano counsels against importing U.S. equitable doctrines into treaty operation. In that posture, judicial estoppel was treated as an “extra-treaty” defense that cannot defeat a mandatory return on these facts—particularly where doing so would invert the Convention’s core mechanism (return to habitual residence) based on petitioner misconduct.

The dissent forcefully argued that judicial estoppel should be available and applied, relying on domestic estoppel authorities and the deterrence-of-forum-shopping purpose. The majority’s response is notable: it framed White’s estoppel request as an attempt to add a new affirmative defense to return, which would undercut uniform international interpretation and exceed what the Convention’s text and Supreme Court guidance permit.

5) Injunctions and comity: federal courts cannot “command” foreign custody adjudication

The most concrete remedial holding is the vacatur of the preliminary injunction. The Fifth Circuit held the district court’s directive that the “Canadian Court shall decide[] the child custody dispute” violated comity principles governing interference with foreign tribunals. Because the Texas restraint was designed to enforce that improper command to Canada, the Fifth Circuit vacated the Texas injunction as well. The court stressed the narrowness of this holding: it did not deny that habitual residence generally fixes the custody forum; it denied that a U.S. federal court may operationalize that principle by ordering a foreign sovereign’s courts to act (and then enjoining state litigation as enforcement leverage).

C. Impact

  • Anti-categorical approach reaffirmed in “temporary move” settings: Litigants should expect habitual residence to remain a totality inquiry even where a domestic court initially described an international relocation as temporary. “Temporary” labels will not automatically control; integration and endurance can outweigh litigation-era intent.
  • Rights-of-custody proof may be streamlined via foreign recognition orders: The court’s willingness to affirm based on a foreign court’s recognition/supersession of another jurisdiction’s order provides a pragmatic pathway where foreign statutory questions are complex or contested.
  • Consent defense constrained by practicality: The opinion resists turning continued participation in an ongoing custody case—after jurisdictional challenges are rejected— into presumptive “consent,” reducing incentives for strategic arguments that force a parent to choose between participation and preserving Hague remedies.
  • Judicial estoppel as a return-blocking device is disfavored in the Fifth Circuit: While not phrased as an absolute across all conceivable cases, the court’s reasoning (text, uniformity, Lozano) makes it difficult to deploy judicial estoppel to defeat a Convention return remedy in future Fifth Circuit cases.
  • Clear boundary on injunction practice post-return: Federal courts ordering return should be cautious about attempting to manage downstream custody jurisdiction via orders directed at foreign courts or state judges. The opinion signals that the proper mechanism is the return order itself, not a supervisory injunction regime.

IV. Complex Concepts Simplified

  • Habitual residence: Not “domicile” or “legal residence.” It is the place the child is practically “at home,” assessed by lived facts (schooling, community, stability), not by rigid rules.
  • Wrongful retention: Keeping a child in a country/state beyond the agreed or lawful scope when the child’s habitual residence is elsewhere and the retention breaches the other parent’s custody rights.
  • Rights of custody vs. rights of access: “Custody” includes the right to determine where the child lives (Article 5(a)); “access” refers to visitation/communication. Only custody-right breaches trigger mandatory return.
  • Article 13(a) consent defense: A narrow exception allowing a court to refuse return if the petitioner consented to the removal/retention. The focus is on the petitioner’s subjective intent before the contested act.
  • Judicial estoppel: A domestic equitable doctrine preventing a party from taking inconsistent positions in different proceedings. This opinion treats it as generally out of place when used as an extra-textual bar to a treaty’s mandatory return command.
  • International comity: Respect between sovereign legal systems. U.S. courts should be highly restrained about orders that purport to direct what foreign courts must do.

V. Conclusion

Moreau v. White delivers two practical rules for Hague Convention litigation in the Fifth Circuit. First, habitual residence remains a totality-of-the-circumstances inquiry even when an international move began under a domestic court’s “temporary” authorization; courts will prioritize where the child is actually “at home,” and appellate review will be highly deferential. Second, while federal courts can order return, they may not convert a return order into a supervisory command to foreign sovereign courts—or enforce such a command by enjoining state custody litigation. Along the way, the court strongly signaled that judicial estoppel is not an appropriate extra-treaty mechanism to defeat the Convention’s return remedy.
