J.P. v M.M. (Approved)

Smart Summary

Factual and Procedural Background

This judgment, delivered by Judge O'Donnell on 13 May 2026, concerns an application by the Applicant seeking the summary return of a minor child to State A under the Child Abduction and Enforcement of Custody Orders Act 1991 and the Hague Convention 1980. The child was born on 20 April 2023. The Respondent brought the child from State A to State B in March 2025. The application is governed by Article 12 of the Convention because the period between removal and commencement of proceedings was less than one year. The Respondent conceded, for the purposes of the proceedings, that the Applicant had rights of custody under State A law and that the child was habitually resident in State A immediately before removal. The contested issues narrowed to two defences under Article 13: (1) alleged prior consent by the Applicant to the child's relocation based on a written note dated June 2022; and (2) that return would expose the child to a grave risk or intolerable situation, primarily due to the Respondent's diagnosed depressive illness and related risks to the child. The court refused the Applicant's return application and listed the case for final orders on 19 May 2026.

Legal Issues Presented

Whether the Applicant had given clear, real and unequivocal consent to the child's removal such that the Article 13(a) consent defence applies.
Whether ordering the child's return would expose the child to a grave risk or an intolerable situation under Article 13(b) of the Convention.
If either defence is established, whether the court should exercise its discretion to refuse the return order.

Arguments of the Parties

Applicant's Arguments

The Applicant accepted signing the June 2022 note and contended it evidenced consent that the child be raised in State B; consent should be evaluated against established legal principles.
The Applicant disputed allegations of drug/alcohol misuse and controlling behaviour, asserting reduced use since 2021 and denying violence or stalking; he said he would continue financial support and housing arrangements if return occurred.
The Applicant submitted the Respondent's mental health evidence did not meet the high threshold required for the grave risk exception and that welfare disputes belong to the courts of State A.

Respondent's Arguments

The Respondent relied on the June 2022 note as evidence of the Applicant's consent and argued there was no clear withdrawal prior to removal.
The Respondent alleged long-standing drug and alcohol misuse and controlling behaviour by the Applicant, and that those matters, together with her mental health, placed the child at grave risk if returned.
The Respondent relied primarily on evidence that a forced return would precipitate a relapse of her depressive illness, creating an intolerable situation for the child; she adduced expert psychiatric evidence and contemporaneous medical notes.

V.R. v C.O'N [2018] IEHC 316	Illustrates context in which visa/immigration issues may or may not prevent return; emphasises trust in requesting State's courts.	Used to show that exceptional circumstances (e.g. clear primary caregiver issues and certainty of visa denial) may justify refusal, but such cases are rare.
W (Child Abduction; Intolerable Situation) [2018] EWCA Civ 664	Example where return was refused due to children's young age, mother's primary caregiving role and certainty of visa denial causing separation.	Referenced as part of discussion on when immigration/visa issues can create an intolerable situation.
Re G (Abduction: Consent/Discretion) [2021] 2 FLR 972	Addresses timing and withdrawal of consent; withdrawal must be communicated before removal; consent can be advanced but must remain operative.	Relied on by the Respondent regarding withdrawal/continuing operation of advance consent; principles applied in consent assessment.
Re P-J (Children) (Abduction: Consent) [2009] 2 FLR 1051	Advance consent to future removal can be valid but must be operative at time of removal and based on objectively verifiable conditions.	Relied upon to support Respondent's submission that earlier consent need not be proximate to removal, but remain operative.
Re G (Abduction: Consent/Discretion) [2021] EWCA Civ 139	Summarises the practical, fact-specific approach to consent; consent is infrequently proved and must be clear and unequivocal.	Adopted by the court as a helpful elaboration of consent principles and applied to the June 2022 note.
Re E (Children) [2011] 2 FLR 758	Discusses psychological harm to children from a parent's mental illness and the importance of available mitigation measures on return.	Used to compare diagnoses (adjustment disorder v depressive illness) and to analyse availability of mitigatory measures in the requesting State.
Re S (A Child) (Abduction: Rights of Custody) [2012] 2 FLR 442	Explains that if a court finds a grave risk under Article 13(b) it is difficult to envisage ordering return notwithstanding the technical discretion.	Quoted to support the proposition that finding the grave risk generally precludes ordering return.
ML v CJ [2013] IEHC 641	Example of refusal of return where respondent was primary carer and relapse of mental health on return would be intolerable for children.	Considered a close analogue; relied on to support finding that relapse would create an intolerable situation for the child.
P.L. v. E.C. [2009] 1 IR 1	Reiterates high threshold for Article 13(b) and warns against turning Convention hearings into welfare inquiries.	Invoked by Applicant to stress burden and summary nature of Convention proceedings; court balanced against psychiatric evidence.
A.S. v P.S [1998] 2 I.R. 244	Discusses the heavy burden to satisfy Article 13(b) and cautions about substituting welfare decisions for jurisdictional ones.	Referred to in support of the general legal framework and high burden for grave risk.
Re HB (Abduction: Children's Objections) [1997]1 F.L.R.392	Addresses the Convention's objective and the heavy burden required to establish Article 13(b).	Quoted via other authorities to reinforce the required standard for grave risk.
Re. K. (Abduction: Child's Objections) [1995] 1 F.L.R. 977	Affirms the high evidential burden for grave risk and that returning courts must trust requesting State's justice system.	Applied as part of the court's exposition of the grave risk standard.
R.K. v. J.K. (Child Abduction: Acquiescence) [2000] 2 I.R. 416	Clarifies the high test and burden in grave risk cases and is cited in subsequent Irish authority.	Used to support the position that grave risk must be shown clearly before refusing return.
Friedrick v. Friedrick (1996) 78F 3d 1060	Suggested that grave risk exists in two scenarios: imminent danger (e.g. war) or serious abuse/neglect where requesting State cannot/will not protect the child.	Cited as illustrative authority for the types of situations that may meet the grave risk test.
Minister for Justice (E.M.) v. J. M. [2003] 3 I.R. 178	Reiterates that grave risk requires a high showing and that custody/welfare issues are for the courts of habitual residence.	Referred to as reinforcing caution about summary Convention proceedings and the high threshold for Article 13(b).

Court's Reasoning and Analysis

The court proceeded from Article 12 because the retention period was under one year and accepted, for the purposes of the hearing, that the Applicant enjoyed and was exercising custody rights and that the child was habitually resident in State A immediately prior to removal. The court then analysed the two Article 13 defences relied upon by the Respondent.

On consent, the court applied established principles requiring the person asserting consent to prove it on the balance of probabilities with clear and cogent evidence that consent was real, positive and unequivocal. The only material evidential basis was a short written note dated June 2022 stating the parties "agree to move to State B in the event that we have children by the time the eldest is five years of age." The court concluded that the note, viewed in context (signed before the child was born, at a delicate time, and against later conduct indicating shared care and post-separation arrangements), did not demonstrate the necessary clear and unequivocal consent to the unilateral removal that occurred in March 2025. The court therefore rejected the consent defence.

On grave risk under Article 13(b), the court considered the Respondent's allegations about the Applicant's conduct but found those factual disputes either conflicted or matters appropriately for custody proceedings in State A. The court gave primary weight to independent psychiatric evidence (assessment by an Expert Psychiatrist) and contemporaneous medical notes. The Expert Psychiatrist's opinion—accepted by the court—was that the Respondent suffers a treated mild-to-moderate depressive illness requiring medication, therapy and significant social supports; there is a real risk of relapse, and relapse would likely be more severe and materially impair her capacity to care for the child. The Expert Psychiatrist further explained that social supports available in State B were a significant protective element not replicated in State A. The court found it probable that a forced return and associated stressors (including housing/financial pressures and litigation) would precipitate relapse, negatively affecting the child's emotional development and creating an intolerable situation for the child. Applying the high Convention standard and comparing authorities (distinguishing cases of adjustment disorder where mitigation was available), the court concluded that the Respondent had established the grave risk/intolerable situation defence in Article 13(b).

Finally, the court addressed discretion. Relying on authority that establishing Article 13(b) confers a discretion which in practice will rarely be exercised to order return, the court exercised its discretion in favour of refusing the return order.

Holding and Implications

REFUSED

Holding: The court refused the Applicant's application for the summary return of the child under the Convention, having found the Article 13(b) defence (grave risk/intolerable situation) established on the evidence and having exercised its discretion not to order return. The court also found that the June 2022 note did not constitute clear and unequivocal consent to the removal.

Implications: The direct consequence is that the child's summary return to State A was refused; the matters of custody and welfare remain to be litigated in the competent courts of State A. The judgment does not purport to set a new legal principle beyond applying established Convention jurisprudence to the facts; it emphasises the high threshold for Article 13(b) but also confirms that where credible expert evidence demonstrates a real and significant risk of relapse of a parent's psychiatric illness, compounded by lack of essential social supports in the requesting State, return may properly be refused.
