Depressive Illness, Social Supports, and “Intolerable Situation”: Article 13(b) Bars Return Where Relapse Risk Cannot Be Mitigated

J.P. v M.M. (Approved) [2026] IEHC 298 — High Court of Ireland (Family Law), O’Donnell J., 13 May 2026.

1. Introduction

This was a Hague Convention return application brought by the applicant father seeking the summary return of a young child to New Zealand. The respondent mother had brought the child from New Zealand to Ireland in March 2025. The proceedings issued in June 2025, so the case fell under Article 12 (less than one year), making return the default outcome unless a defence under Articles 13 or 20 was established.

For the purposes of the application, the mother accepted that the father had rights of custody under New Zealand law and was exercising them, and she accepted (for Convention purposes) that the child was habitually resident in New Zealand at the time of removal. The dispute therefore narrowed to two asserted Article 13 defences:

  • Consent (Article 13(a)): reliance on a short written note signed in June 2022 (before the child’s birth) said to permit a move to Ireland.
  • Grave risk / intolerable situation (Article 13(b)): primarily based on the mother’s depressive illness and the likely effect of a forced return on her mental health, with consequential harm to the child.

A key feature of the case was the court’s decision to adjourn to obtain independent psychiatric evidence (Professor Patricia Casey), reflecting the court’s concern to ground any Article 13(b) determination in precise clinical evidence rather than generalised assertions.

2. Summary of the Judgment

  • Consent defence rejected: the 2022 note did not amount to clear and cogent evidence of a real, positive, unequivocal consent to the unilateral, unannounced removal that occurred in March 2025.
  • Article 13(b) defence upheld: the mother proved, to the requisite high standard, that a forced return would expose the child to an intolerable situation due to a real and predictable risk of relapse in the mother’s depressive illness, exacerbated by the absence of meaningful social supports in New Zealand.
  • Return refused: having found Article 13(b) established, the court refused return and observed that, in reality, it is “impossible to conceive” of circumstances where return would nonetheless be ordered once a grave risk is found (adopting Lord Wilson’s observation in Re: S (A Child) (Abduction: Rights of Custody) [2012] 2 FLR 442).

3. Analysis

3.1 Precedents Cited (and how they shaped the result)

(a) The Convention’s purpose and the “summary” nature of return proceedings

The judgment reaffirmed that Hague proceedings do not decide custody merits; they determine the proper forum and secure prompt return, subject to limited exceptions. O’Donnell J. adopted the “animating principle” described in In A.K. v. U.S. [2022] IECA 65 (with reference to CT v. PS [2021] IECA 132) that welfare disputes are generally best resolved in the child’s habitual residence jurisdiction, discouraging unilateral self-help removals.

This framing mattered in two ways:

  • It narrowed the inquiry to whether a Convention defence was established, not whether Ireland was the “better” place for the child.
  • It underpinned the court’s dismissal of disputed allegations about the father’s behaviour as matters for New Zealand custody litigation, absent clear and compelling evidence meeting Article 13(b).

(b) Consent under Article 13(a): Irish and UK guidance on “real, positive, unequivocal” consent

The Supreme Court authority S.R. v M.M.R. [2006] IESC 7 (approving Hale J. in Re K (Abduction: Consent) [1997] 2 F.L.R. 212) set the framework: consent must be proved by the removing parent on the balance of probabilities by clear and cogent evidence; it must be real, positive and unequivocal; it may be inferred from conduct but is assessed in the round.

The parties also relied on UK Court of Appeal authority addressing advance consent and withdrawal:

  • Re P-J (Children) (Abduction: Consent) [2009] 2 FLR 1051 (Ward L.J.): advance consent can be valid, but must remain operative at removal; any condition must be objectively verifiable and not left to one party’s subjective determination.
  • Re G (Abduction: Consent/Discretion) [2021] 2 FLR 972 / Re G (Abduction: Consent/Discretion) [2021] EWCA Civ 139 (Peter Jackson L.J.): consent is fact-specific; assessed by “commonsense realities” rather than contract law; must relate to removal broadly within both parties’ contemplation; can be withdrawn prior to removal; consent/withdrawal must be made known to the removing parent.

O’Donnell J. treated Peter Jackson L.J.’s summary as consistent with Irish Supreme Court principles, using it as a practical elaboration. Applying these authorities, the court found the 2022 note insufficient: it contemplated moving “as a family unit” and was not referable to the unilateral, clandestine relocation that actually occurred; the mother’s own evidence (that she did not inform the father because she feared he would stop her) undermined the claim that she genuinely understood the father’s consent to remain operative and unequivocal in March 2025.

(c) Article 13(b): the high threshold, “clear and compelling evidence”, and mitigation

Irish authority emphasising the narrow scope and high threshold of Article 13(b) was central:

  • C.A. v. C.A. [2010] 2 IR 162: “clear and compelling evidence” is required.
  • P.L. v. E.C. [2009] 1 IR 1: return is the norm; Article 13(b) carries a heavy burden; courts must not convert Hague hearings into welfare determinations; trust must be placed in the requesting state’s courts.
  • Minister for Justice (E.M.) v. J. M. [2003] 3 I.R. 178 and R.K. v. J.K. (Child Abduction: Acquiescence) [2000] 2 I.R. 416 (including the cited US approach in Friedrick v. Friedrick (1996) 78F 3d 1060): the exception is confined; general welfare concerns are for the habitual residence court.

The judgment also relied on UK and Irish cases clarifying that “grave risk” can arise indirectly through harm to the abducting parent that then impacts the child:

  • Re E (Children) [2011] 2 FLR 758: (i) “grave” is more than “real”; (ii) exposure to harmful effects of abuse of a parent can qualify; (iii) the court must consider whether protective measures can mitigate the risk on return.
  • Re S (A Child) (Abduction: Rights of Custody) [2012] 2 FLR 442: the critical question is what will happen if the child returns with the mother; if the mother’s return anxieties would create an intolerable situation for the child, return should be refused. The court also cited Lord Wilson’s practical observation about discretion once grave risk is found.
  • ML v CJ [2013] IEHC 641: return refused where the primary carer’s mental health breakdown on return would be intolerable for the children; while risk prediction is difficult, the court treated the risk as grave based on mental history and medical opinion.
  • V.R. v C.O'N [2018] IEHC 316 (and re W (Child Abduction; Intolerable Situation) [2018] EWCA Civ 664): visa/participation difficulties rarely bar return; refusal is exceptional, particularly where very young children risk prolonged separation from the primary carer; trust in the requesting state remains important.

O’Donnell J. used this line of authority to structure the inquiry: (i) identify whether the predicted harm crossed the “grave” threshold, and (ii) determine whether that harm could be mitigated through measures available in the requesting state. The critical finding was that while New Zealand could provide medical treatment, the missing mitigatory factor was “real and meaningful” social support—present in Ireland and absent in New Zealand—rendering relapse risk unmitigable.

3.2 Legal Reasoning

(a) Consent: why the 2022 note did not do the legal work required

The court accepted the father signed a short note stating the parties “agree to move to Ireland” if they had children by the eldest’s fifth birthday. But consent under Article 13(a) is not an exercise in construing a contract; it is an evaluation of whether the left-behind parent clearly and unequivocally consented to the actual removal in broadly contemplated circumstances.

The reasoning turned on three interlocking points:

  • Mismatch between contemplated and actual removal: the note envisaged a family relocation, not unilateral removal after marital breakdown.
  • Operativity at the time of removal: even if “advance consent” can exist, the court was not persuaded it remained operative after subsequent events (including the family’s living arrangements and parenting pattern in New Zealand).
  • The mother’s own conduct evidence: her decision to leave without informing the father because she believed he would try to stop her pointed away from any genuine belief that she had unequivocal ongoing permission.

On that basis, the consent defence failed.

(b) Grave risk / intolerable situation: the centrality of psychiatric evidence and the “social support” factor

The court separated (i) disputed allegations about the father’s substance use/controlling behaviour, from (ii) the mental health pathway. On the first, it held the evidence was conflicting and not readily resolvable in summary proceedings and, in any event, such matters were capable of adjudication and management by New Zealand courts. That approach reflected the restraint mandated by P.L. v. E.C. [2009] 1 IR 1 and the trust principle.

The second strand succeeded because the court accepted, as facts grounded in expert evidence, that:

  • The mother had a mild-to-moderate depressive illness (not mere unhappiness), treated with medication and therapy and presently improving.
  • There was a real risk of relapse, with relapse likely to be more severe (moderate depression).
  • Forced return, combined with foreseeable stressors (including housing/financial pressures and litigation), would be a prominent trigger.
  • Relapse would likely impair parenting capacity and expose the child (very young; mother as primary carer since birth) to a serious negative impact amounting to an intolerable situation.

Crucially, the court treated mitigation not as a binary question (“is medical care available in New Zealand?”) but as a multi-element clinical reality. Professor Casey’s evidence identified three necessary treatment supports: medication, talking therapy, and deep social support (more than an ordinary friendship network). The court accepted that while the first two were likely available in New Zealand, the third was not—making relapse risk not reasonably mitigable.

This is the judgment’s most significant doctrinal move: it recognises that, in some cases, the “protective measures” analysis (prominent in Re E (Children) [2011] 2 FLR 758) must include the availability of meaningful social supports, not just formal medical services or undertakings.

(c) Discretion after Article 13(b)

Formally, a successful Article 13(b) defence confers a discretion to refuse return. Practically, the court adopted Lord Wilson’s observation in Re: S (A Child) (Abduction: Rights of Custody) [2012] 2 FLR 442 that it is “impossible to conceive” of circumstances where it would be legitimate to order return once such a grave risk is found. O’Donnell J. nonetheless expressly considered discretion and refused return.

3.3 Impact

(a) Article 13(b) and parental mental health: a structured evidential template

The decision reinforces that parental mental health can ground an Article 13(b) defence where the impact on the child is sufficiently serious. Its practical influence lies in how it demands a clinically specific, mechanism-based account:

  • diagnosis (depressive illness vs adjustment disorder),
  • baseline severity,
  • treatment response,
  • relapse probability and likely severity,
  • identifiable triggers linked to forced return, and
  • child-impact pathway (how impaired parenting would expose the child to intolerability).

The court’s willingness to adjourn for an independent expert underscores that Article 13(b) findings—particularly those turning on predicted relapse—should rest on robust, testable evidence, not solely GP letters or party affidavits.

(b) “Protective measures” must be realistic, not purely legal

The judgment extends the mitigation inquiry beyond whether the requesting state’s courts and services are competent. Even where medical services are comparable, return may still be refused if a key stabilising factor—here, meaningful social supports—cannot realistically be replicated on return, and the absence of that factor makes relapse risk grave and unmanageable.

(c) Consent: advance, informal notes will be closely scrutinised for “fit”

On Article 13(a), the judgment signals that a brief informal document (even signed) will not necessarily amount to operative consent where:

  • it predates the child’s birth by a substantial period,
  • it contemplates a different type of move (family relocation vs unilateral removal), and
  • later family developments render it implausible as an unequivocal permission for the later removal.

The removing parent’s own behaviour (particularly concealment motivated by fear the other parent would object) may be treated as powerful evidence that consent was not clearly understood to exist at the time of removal.

4. Complex Concepts Simplified

  • Habitual residence: the child’s “home base” for Convention purposes. If the child was habitually resident in New Zealand immediately before removal, New Zealand is normally the forum for deciding custody merits.
  • Wrongful removal: removal that breaches the other parent’s custody rights being exercised under the law of the habitual residence state.
  • Article 12 (under one year): if proceedings commence within one year of removal/retention, the court must order return unless a defence is proven.
  • Article 13(a) consent: the left-behind parent must have clearly and unequivocally agreed to the child’s removal. The court looks at real family-life context, not contractual formalities.
  • Article 13(b) grave risk / intolerable situation: a narrow exception requiring a high evidential threshold. “Grave” means seriously serious—not merely “real.” Harm may be indirect, e.g., where a parent’s mental illness triggered by return would expose the child to intolerability.
  • Protective measures / mitigation: steps that can reduce risk on return (court orders, undertakings, services). This case highlights that mitigation can depend on practical realities such as deep social supports, not only the availability of medical treatment.
  • Discretion after a defence is proven: technically the court may still order return, but this judgment—following Re: S—treats that as exceptional to the point of being hard to envisage once a grave risk is found.

5. Conclusion

J.P. v M.M. [2026] IEHC 298 is a significant Irish Hague Convention decision on two fronts. First, it tightens the analysis of alleged “consent” by insisting that advance, informal agreements must be demonstrably operative and must correspond to the type of removal that actually occurred. Second—and more importantly—it affirms that Article 13(b) may be established where forced return would predictably precipitate relapse in a primary carer’s diagnosed depressive illness, placing a very young child in an intolerable situation, particularly where the risk cannot be mitigated because a key stabilising factor (meaningful social support) is absent in the requesting state.
