Allegations of “Parental Alienation Syndrome” Do Not Legally Mandate a Specialist Expert Under s.32 (and Disagreement with Evidential Weight Is Not for Judicial Review)

Case: L.H. (Custody And Access Proceedings: Court-Appointed Expert) v P.J (Approved) [2026] IEHC 520

Court: High Court (Judicial Review)

Judge: Simons J.

Date: 31 July 2026

Subject: Leave to apply for judicial review of a Circuit Court order in Guardianship of Infants Act 1964 custody/access proceedings

1. Introduction

This decision concerns an application by the child’s father (the applicant) for leave to pursue judicial review of a Circuit Court order made in ongoing custody and access proceedings under the Guardianship of Infants Act 1964. The child (a teenage boy) had expressed a consistent wish not to have in-person access or video contact with the father. The Circuit Court ultimately made orders continuing limited indirect contact (letters/updates) and providing that in-person and video contact would be subject to the child’s wishes.

The father’s central argument was that once he raised what he labelled “parental alienation syndrome”, the Circuit Court was legally obliged to appoint (and/or rely upon) an expert with specialist “parental alienation” expertise—effectively limiting the court’s options to a small cohort of professionals selected by him.

This was the father’s second attempt to challenge the management of the same family-law proceedings by judicial review; the first was refused in L.H. v. P.J. [2024] IEHC 340.

2. Summary of the Judgment

Simons J. refused leave. Even applying the low threshold of arguability, the father had not identified any statutory or legal rule requiring a s.32 court-appointed expert to possess specialist expertise in “parental alienation” (or “parental alienation syndrome”) merely because the allegation is made.

The Court held, in essence, that:

  • For a child’s views expert appointed under s.32(1)(b), the qualifications are governed by the 2018 Regulations, which do not require any “parental alienation” specialism.
  • A social worker meeting the regulatory criteria is eligible; acknowledgment in evidence of not having a “parental alienation” specialism does not retroactively invalidate the appointment.
  • Complaints that the Circuit Court should have evaluated or weighted expert evidence differently are merits-based and, applying Sweeney v. Fahy [2014] IESC 50, do not ordinarily disclose an error of law amenable to judicial review.
  • The father’s reliance on the controversial construct of “parental alienation syndrome” could not generate a mandatory legal rule compelling a contested diagnostic approach.
  • ECtHR authorities relied upon did not support the asserted obligation to appoint a specialist in “parental alienation syndrome”.

3. Analysis

3.1 Precedents Cited and Their Influence

  • G. v. Director of Public Prosecutions [1994] 1 IR 374
    The classic Irish test for leave: the applicant must show, prima facie, a stateable ground and an arguable case in law, and that judicial review is the only effective remedy (or is more appropriate than alternatives). Simons J. applied this as the foundational framework.
  • O'Doherty v. Minister for Health [2022] IESC 32, [2023] 2 IR 488, [2022] 1 ILRM 421
    O’Donnell C.J. clarified that the leave threshold is one of arguability—not “reasonable prospects” or “likelihood” of success—and that the same test applies whether leave is sought ex parte or on notice. Simons J. emphasised this to show he was applying a low bar, yet still found no arguable legal obligation supporting the father’s claim.
  • D.K. v. P.I.K. [2021] IECA 54
    Collins J. described s.32(1)(b) as a specialised statutory mechanism to “determine and convey” a child’s views; the expert’s role is not a mere “ask-and-repeat” exercise. Simons J. used this to anchor the statutory purpose of child’s views expertise—while rejecting the leap that it requires any additional, allegation-driven specialism.
  • J.Mc.D. v. P.L. [2009] IESC 81, [2010] 2 IR 199
    Denham J. explained (in the s.47 Family Law Act 1995 context) that an expert report is evidence, not determinative; the court remains decision-maker and may reject recommendations. Simons J. treated this as applicable by analogy to s.32: the s.32 expert assists but does not decide.
  • L.H. v. P.J. [2024] IEHC 340
    The earlier refusal of leave between the same pseudonymous parties: Jackson J. had already rejected the argument that alleging parental alienation compels appointment from a party’s chosen cohort, and held that a suitably qualified social worker was an “expert” under the 2018 Regulations. Simons J. agreed with the substance but stated he was not deciding the point via res judicata/issue estoppel.
  • F.G. v. Child and Family Agency [2018] IESC 28
    The Supreme Court held that refusal of leave does not necessarily bar a later application, though rerunning the same challenge without material change may be abusive. Simons J. cited this to explain why he considered eligibility afresh rather than relying on preclusion doctrines.
  • Sweeney v. Fahy [2014] IESC 50
    A core judicial review boundary case: JR targets legality not correctness; adequacy of evidence ordinarily does not render a decision unlawful; where appeals exist, JR is generally inappropriate. This was central to rejecting the father’s attempt to re-litigate the Circuit Court’s evaluation of expert evidence following cross-examination.
  • C.G. v. B.G. [2019] IEHC 15
    Relied upon by the father for the proposition that parental alienation allegations require specialist investigation. Simons J. distinguished it: Binchy J. did not lay down a universal rule requiring a “parental alienation” specialist, but rather recognised the need for professional input in the circumstances of that case.
  • ECtHR: Kutzner v. Germany (App. no. 46544/99, 26 February 2002) and Y.C. v. United Kingdom (App. no. 4547/10, 13 March 2012)
    The Court found these did not support any asserted Convention-based obligation to appoint a “parental alienation syndrome” specialist. Kutzner was about disproportionality in separating a family; Y.C. confirmed domestic courts need not order further assessments in every case and may rely on existing professional evidence.

3.2 Legal Reasoning

(a) The statutory architecture of s.32: two distinct functions

A key analytical move was the Court’s insistence on separating:

  • s.32(1)(a): a report on “any question affecting the welfare of the child”; and
  • s.32(1)(b): appointment of an expert to “determine and convey the child’s views”.

That distinction mattered because the Guardianship of Infants Act 1964 (Child's Views Expert) Regulations 2018 govern eligibility for (b), not (a).

(b) Eligibility under the 2018 Regulations is profession-and-experience based, not allegation-driven

The father’s core submission—“parental alienation syndrome alleged, therefore specialist required”—failed at the threshold because the 2018 Regulations set out explicit categories (including social workers with requisite experience) and do not add an extra “parental alienation” credential.

The Regulations also include functional safeguards: Regulation 5 requires independence and, crucially, requires the expert to ascertain whether a child’s views result from undue influence. The Court treated this as the statutory “home” for concerns often raised under the parental-alienation label, without importing contested diagnostic frameworks as legal requirements.

(c) Appointment versus performance: cross-examination is the ordinary control mechanism

The father also argued that once the expert acknowledged in cross-examination she did not claim “parental alienation” expertise, the Circuit Court should not have accepted or acted upon her evidence. Simons J. treated this as a complaint about admissibility/weight and the trial court’s evaluation, not about a legal incapacity that could be corrected by judicial review.

The High Court stressed that the Circuit Court was not operating under misapprehension: the limits of expertise were “placed squarely” before it. The father had cross-examined on qualifications, methodology, and conclusions. Whether to accept, reject, or qualify reliance on that evidence was a matter for the Circuit Court’s assessment.

(d) Judicial review cannot be used as a disguised appeal on evidential weight

Applying Sweeney v. Fahy [2014] IESC 50, the judgment reiterates a familiar but practically important point in family litigation: where evidence has been heard and tested, a later claim that the trial judge should have given it less weight, or should have required different expert evidence, is ordinarily a merits challenge and not reviewable (absent a fundamental legal error, complete absence of evidence on a necessary matter, or an irrationality threshold being met).

(e) The controversy surrounding “parental alienation syndrome” undercuts any claim of a mandatory approach

The father’s case was further weakened by his invocation of Gardner’s “eight symptoms” and a “full Parental Alienation Test”. Simons J. relied on a Department of Justice-commissioned review (not as determinative science, but as illustrating controversy) to show:

  • there is no agreed international definition;
  • there is no agreed “gold standard” measurement;
  • attempts to include PAS/PAD in ICD/DSM have not succeeded; and
  • literature is polarised and reliability/validity of instruments is contested.

The Court’s legal conclusion was narrow: a party cannot create a mandatory legal requirement by invoking a contested clinical construct and insisting on a niche methodology, thereby constraining the statutory discretion and the regulatory scheme.

(f) ECHR arguments: interpretive obligation does not supply the alleged rule

The Court explained the Convention’s indirect domestic effect via the European Convention on Human Rights Act 2003, especially ss.2 and 4, and rejected the proposition that the cited ECtHR cases required a specialist in “parental alienation syndrome” or a further assessment. The thrust of Y.C. v. United Kingdom was, if anything, that domestic courts may decline further assessments where existing evidence suffices and further assessment would introduce disruption/delay without resolving concerns.

3.3 Impact

  • Clarification for s.32 practice: Allegations framed as “parental alienation” do not, of themselves, narrow the court’s statutory discretion to appoint a child’s views expert who meets the 2018 Regulations. Eligibility remains rooted in the regulatory categories and experience, not in party-driven demands for a particular sub-specialism.
  • Reinforced boundary between appeal and judicial review: The judgment is a practical warning that dissatisfaction with how a family court assessed expert evidence—especially after cross-examination— is not normally justiciable by judicial review.
  • Resists “diagnosis-by-litigation”: The Court’s approach reduces the risk that contested diagnostic labels become de facto gatekeepers for expert appointment, and emphasises the statutory concepts of “undue influence” and best interests as the legal touchstones.
  • Future litigation strategy: Parties who dispute a s.32 report are steered toward trial tools (cross-examination, competing evidence where permissible, submissions on weight) and orthodox appellate routes, rather than collateral JR challenges to expert selection or evidential evaluation.

4. Complex Concepts Simplified

  • Section 32 report: A court-commissioned report to help the judge—either about the child’s welfare (s.32(1)(a)) and/or to ascertain and present the child’s views (s.32(1)(b)). It is evidence, not a decision.
  • “Child’s views expert” (2018 Regulations): A professional (e.g., psychologist, social worker, etc.) with specified experience and insurance, appointed to determine and convey the child’s views.
  • Undue influence: The statutory concern that a child’s expressed views may be shaped improperly by another person. Regulation 5 requires the expert to assess this—without prescribing any single clinical model.
  • Leave for judicial review (arguability): Permission stage; the applicant must show an arguable legal claim. It is a low threshold, but it still requires some legal rule arguably breached.
  • Judicial review vs appeal: Appeal asks “was the decision wrong?”; judicial review asks “was the decision made lawfully?” Disputes about weight of evidence are usually for appeal, not JR.
  • “Parental alienation syndrome”: A contested concept; the Court did not decide its scientific validity. The legal point was that contested science cannot be converted into a mandatory legal appointment criterion.

5. Conclusion

Simons J. refused leave because the father’s proposed challenge did not disclose an arguable legal basis for insisting that a s.32 expert must have a “parental alienation” specialism, nor for asserting that the Circuit Court acted unlawfully by weighing the expert’s evidence after the limits of her expertise were explored in cross-examination. The judgment strengthens two linked propositions: (i) s.32 appointments are governed by statute and the 2018 Regulations, not by allegation-driven demands for niche expertise, and (ii) judicial review is not a vehicle to re-run the trial court’s assessment of expert evidence in custody/access proceedings.
