S (A Child) (Abduction: Article 13(b)) – Court of Appeal Clarifies the Correct, Holistic Test for “Grave Risk” and the Inadequacy of Abstract Protective Measures

1. Introduction

In S (A Child) (Abduction: Article 13(b)) [2025] EWCA Civ 1119 the Court of Appeal (Moylan, Asplin and Elisabeth Laing LJJ) revisited the interpretation of Article 13(b) of the 1980 Hague Child Abduction Convention. The case concerned a 7-year-old boy, S, unilaterally removed by his mother (M) from Ireland to England. The father (F) sought a summary return order. At first instance the judge concluded that the mother’s Article 13(b) defence failed and ordered S’s return. On appeal, the Court of Appeal found “material flaws” in that decision, quashed the return order and dismissed the father’s application outright.

The judgment is significant because it tightens the analytical framework under Article 13(b), insisting that judges:

  • apply the two-stage Re E approach rigorously;
  • consider cumulative risks, including the child’s vulnerabilities and separation from a primary carer;
  • avoid inserting an “immediate harm” gloss; and
  • scrutinise proposed protective measures to ensure they actually neutralise the identified risks.

2. Summary of the Judgment

Moylan LJ held that the first-instance judge:

  • misapplied Re E by failing to ask whether, if true, the mother’s allegations would create a grave risk;
  • improperly relied on a single answer from the Cafcass officer to conclude that there was “no immediate risk”;
  • wrongly discounted the impact of S’s separation from his mother and sibling A; and
  • treated generic undertakings (flights, accommodation, non-molestation, video calls) as sufficient protective measures without analysing their efficacy.

The Court of Appeal therefore:

  • allowed the appeal, set aside the return order;
  • determined the application itself (no remission); and
  • dismissed the father’s return request because a grave risk of psychological harm/intolerable situation was established and could not be mitigated.

3. Analysis

3.1 Precedents Cited

  • In re E (Children) [2012] 1 AC 144
    Corner-stone authority setting a two-stage test: (i) assume allegations true; decide whether they cross the Article 13(b) threshold; (ii) examine protective measures. Moylan LJ stressed that the first-instance judge simply omitted stage (i).
  • In re D (A Child) [2007] 1 AC 619
    Defines “intolerable” as “a situation which this particular child in these particular circumstances should not be expected to tolerate”. Adopted to highlight the need to factor in S’s special vulnerabilities.
  • In re S (Abduction: Rights of Custody) [2012] 2 AC 257 & In re B (Children) [2023] Fam 77
    Confirm cumulative assessment of overlapping risks.
  • In re A (Abduction: Article 13(b)) [2021] 4 WLR 99 and In re R (Children) [2025] Fam 67
    Establish that forced separation from a primary carer can, itself, satisfy Article 13(b).

The present decision consolidates the above, rejecting any “immediate harm” limitation and underscoring that the risk-assessment role cannot be delegated to a welfare officer.

3.2 Legal Reasoning

The Court of Appeal’s reasoning proceeded in four principal moves:

  1. Correct Framing of the Question
    The judge must first treat M’s allegations (serious physical, sexual, coercive abuse and drug dealing) as factually true. If true, would S face a grave risk? The first-instance judgment never answered that question.
  2. Critical Appraisal of the Evidence
    The single phrase from the Cafcass officer (“no risk immediately”) was incapable of discharging the judicial function: (a) it addressed only immediate risk; (b) the officer had not conducted any safeguarding assessment; (c) she expressly recommended a “full risk and welfare assessment” in Ireland; and (d) Article 13(b) is not confined to the child’s first hours or days back in the requesting state.
  3. Holistic Evaluation of Cumulative Risks
    Three overlapping dangers were identified: (i) placement with an alleged perpetrator of extreme abuse, untested but to be assumed true; (ii) separation from the mother, S’s primary attachment figure, and from sibling A; (iii) the child’s own vulnerabilities — cognitive delay, sensory issues, acute emotional dysregulation. Combined, these satisfied the “grave risk/intolerable situation” threshold.
  4. Protective Measures Scrutinised
    Generic undertakings and the promise of a future welfare report do not grapple with daily care by an alleged abuser or the traumatic removal from the mother. Effective measures must neutralise the identified danger; here they did not. The fallback suggestion that Irish authorities could later remove S from F “compounded rather than ameliorated” the risk.

3.3 Impact of the Decision

The ruling is likely to reverberate in four areas:

  • Trial Practice – First-instance judges must articulate stage (i) of Re E explicitly, outline cumulative risks, and resist short-cuts based on an “immediate harm” inquiry.
  • Expert Evidence – Cafcass or social-work evidence cannot be treated as dispositive on Article 13(b) unless the witness has conducted a full risk assessment.
  • Protective Undertakings – Parties will need to craft concrete, welfare-orientated measures (e.g. supervised contact, interim carers, timetabled assessments) rather than standard form promises.
  • Vulnerable/Neuro-divergent Children – The case underscores that additional weight is given where the child’s developmental or emotional profile renders him or her less able to tolerate disruption or uncertainty.

4. Complex Concepts Simplified

  • 1980 Hague Convention – An international treaty providing speedy return of children wrongfully removed or retained across borders.
  • Article 13(b) – An exception allowing refusal to return where the abducting parent proves a “grave risk” of physical or psychological harm, or an otherwise intolerable situation.
  • Summary Return – A rapid, non-welfare determination focused on jurisdiction, not the ultimate merits of custody.
  • Protective Measures – Undertakings, conditions, or arrangements (often agreed through the Central Authorities) designed to neutralise identified risks so that return can proceed safely.
  • Welfare / Risk Assessment – A detailed appraisal by child-protection professionals, ordinarily requiring more time, evidence and (frequently) factual findings than the summary Hague process allows.

5. Conclusion

S (A Child) re-asserts the centrality of the Re E methodology and warns against diluting Article 13(b) by:

  • restricting analysis to “immediate” harm;
  • viewing separation harm as an impermissible “best-interests” enquiry; or
  • accepting generic undertakings at face value.

The Court of Appeal’s holistic, child-specific approach amplifies the protective purpose of the Convention, ensuring that it is not, in Lady Hale’s words, “turned into an instrument of harm”. Practitioners must now be prepared to evidence risks cumulatively and propose genuinely effective safeguards if they wish to overcome, or rely upon, an Article 13(b) defence.
