Aged-Out Child Defendants: Blameworthy Delay Does Not Justify Prohibition Absent Exceptional Prejudice; Gilchrist-Type Orders May Mitigate Lost Anonymity

1) Introduction

In P.M. v The Director Of Public Prosecutions (Approved) [2026] IEHC 493, Ms Justice Siobhán Phelan considered a judicial review application seeking to prohibit the prosecution of an accused who was a child at the time of the alleged offences but was charged after turning 18. The prosecution arose from an alleged group assault and violent disorder on Henry Street, Dublin (22 February 2022).

The central complaint was that prosecutorial delay caused the applicant to “age out” of the child-specific procedural protections under the Children Act, 2001, particularly the loss of a s. 75 jurisdiction decision (which can permit summary disposal in the Children Court) and associated protections (including reporting/anonymity protections and the child disposal framework).

The High Court heard this case alongside two related “aged-out” applications arising from the same incident (S.B. v. D.P.P. [2026] IEHC 494 and CMcL v. D.P.P. [2026] IEHC 495). A notable factual feature was that the Children Court accepted jurisdiction under s. 75 for four co-accused who were still under 18 when charged, notwithstanding the DPP recommendation for trial on indictment.

2) Summary of the Judgment

  • Blameworthy delay found: The Court held there was inordinate and blameworthy delay, breaching the applicant’s constitutional right to trial with due expedition, particularly given the heightened duty of expedition where the suspect is a child.
  • Relief refused: Despite blameworthy delay, the Court refused prohibition because the prejudice shown did not meet the demanding “truly exceptional circumstances” threshold for restraining prosecution of serious offences.
  • Comparator evidence accepted—but limited: The co-accused outcomes supported only a reasonable possibility (not a probability) that the applicant might have benefited from s. 75 summary jurisdiction if charged while still a child.
  • Sentencing exposure not enough: Increased maximum sentencing exposure, without evidence of a real risk of an inappropriate sentence, was not “irremediable prejudice” sufficient to prohibit.
  • Potential mitigation: The Court indicated it had jurisdiction to consider a Gilchrist-type reporting restriction order to mitigate prejudice arising from loss of statutory anonymity, and invited submissions on scope and form.

3) Analysis

3.1 Precedents Cited and Their Influence

Heightened expedition and the two-stage framework

  • B.F. v. DPP [2001] 1 I.R. 656, [2001] IESC 18 and Donoghue v. DPP [2014] 2 I.R. 762, [2014] IESC 56 were relied upon for the proposition that delay analysis involves:
    1. whether there is blameworthy prosecutorial delay (in child cases, assessed against a heightened duty of expedition); and
    2. whether resulting prejudice, balanced against the public interest in prosecution, warrants prohibition.
    The Court expressly applied this Donoghue structure.

When prejudice “crystallises” in aged-out cases

  • Cash v. DPP [2017] IEHC 234 and Dos Santos v. DPP [2020] IEHC 252 informed the Court’s approach to the relevant period: in an “aged-out” case, the critical period is up to the accused’s 18th birthday, because that is when the child-regime prejudice crystallises and cannot be reversed by later expedition.

Diversion delays as a source of blameworthiness

  • The applicant relied on M.S. v. DPP [2018] IEHC 285, where McDermott J. noted diversion should generally take four to six weeks. While the High Court did not decide whether diversion was inappropriate in principle here, it treated the prolonged diversion timeline as a key unexplained delay contributing to blameworthiness.

Meaning and weight of losing s. 75

  • The legal weight of losing s. 75 was dominated by Supreme Court authority: Doe (No. 1), Doe (No. 2) and Doe (No. 3) v. DPP [2025] IESC 17 and Brophy v. DPP [2026] IESC 7.
  • From Doe (No. 1), Doe (No. 2) and Doe (No. 3) v. DPP [2025] IESC 17, the Court drew:
    • loss of s. 75 is generally not a major factor for prohibition because judicial review courts are usually ill-equipped to reconstruct what the Children Court would have done;
    • even where delay is culpable, prohibition for serious offences requires truly exceptional circumstances and prejudice “beyond the norm”;
    • sentencing remains governed by proportionality, and Circuit Court sentencing is not dictated by District Court views.
  • From Brophy v. DPP [2026] IESC 7, the Court drew:
    • the statutory distinction between children and adults explains divergent procedures and does not, without more, amount to impermissible unequal treatment;
    • sentencing must still reflect the offender’s age/maturity at the time of the offence; culpability does not increase because the person is now an adult;
    • loss of s. 75 typically should not be given great weight in prohibition applications.

Comparator evidence and inference

  • The applicant invoked DPP v. Furlong [2022] IECA 85 to support drawing inferences from comparator cases. The High Court accepted that the fact that co-accused (arising from the same incident) remained in the Children Court could support an inference of a reasonable possibility that the applicant might have benefited from s. 75—while still applying the Supreme Court’s caution against speculative reconstruction.

s. 75 and adult summary disposal

  • The applicant relied on The People (DPP) v. L.E. [2020] IECA 101 to emphasise that s. 75 does not mirror the adult summary/indictment pathway and, in particular, does not operate as a DPP “veto” in the same way—making s. 75 a meaningful procedural protection for children.

3.2 Legal Reasoning

(A) Blameworthy delay

The Court treated the pre-18 period as decisive. The applicant was identified and interviewed in March 2022 (aged 15), yet the file was not sent to the DPP until 21 July 2024—three days before he turned 18. The Court found:

  • the evidential investigation into the applicant’s involvement was effectively complete early (March 2022), so later inactivity needed explanation;
  • general references to workload, operational pressures, and broader investigative activity did not satisfactorily explain why the applicant’s file was not progressed in time to bring him before the Children Court;
  • the lengthy diversion timeline (September 2023 to April 2024) was not adequately explained, even if diversion was not inherently inappropriate.

With the heightened expedition obligation in child cases, the Court held the delay was both excessive and blameworthy.

(B) Prejudice and the balancing exercise

The decisive step was the Donoghue balancing exercise: even with a constitutional breach, prohibition is exceptional and requires prejudice of sufficient gravity.

  • Loss of s. 75 and sentencing exposure: The Court accepted comparator evidence created a reasonable possibility (not more) that the Children Court might have accepted jurisdiction for the applicant, which could have capped custody on summary disposal (e.g., 12 months) rather than leaving him exposed to the Circuit Court’s wider maxima (including up to 10 years for violent disorder on indictment).
  • But sentencing proportionality is a safeguard: Following Doe and Brophy, the Court stressed that if convicted, the Circuit Court must impose an individualised, proportionate sentence reflecting the applicant’s age, maturity, and culpability at the time of the alleged offences; “culpability does not increase” with age.
  • No trial unfairness shown: There was no evidence of lost evidence, unavailable witnesses, or impairment to the defence; therefore, fair trial concerns (in the narrower evidential sense) did not arise.
  • Anonymity prejudice potentially mitigable: The Court considered that a Gilchrist-type order could address reporting/anonymity prejudice stemming from loss of Children Act protections, rather than prohibiting the prosecution.

The Court concluded that increased sentencing exposure and the lost opportunity for s. 75—even accepting a reasonable possibility—did not amount to “irremediable” or “exceptional” prejudice sufficient to outweigh the public interest in prosecuting serious allegations of group violence.

3.3 Impact

  • Comparator evidence is relevant but rarely decisive: This judgment clarifies that even where co-accused from the same incident actually received s. 75 jurisdiction decisions, the High Court may still characterise the applicant’s lost chance as no more than a “reasonable possibility” and may still refuse prohibition under the Supreme Court’s high threshold in Doe and Brophy.
  • Practical focus shifts to mitigation rather than prohibition: The decision signals that, in many aged-out cases, applicants may achieve more through tailored mitigation (especially reporting restrictions) than through attempting to restrain prosecution entirely.
  • Operational pressure explanations may not suffice in child cases: The finding of blameworthy delay, notwithstanding broad claims of workload and complex multi-suspect investigations, reinforces that child cases demand demonstrable expedition and concrete explanations for inactivity.
  • Reporting restriction jurisdiction in JR: The Court’s willingness to entertain a Gilchrist-type order (even where not expressly pleaded as a primary relief) is an important procedural takeaway for future aged-out litigation, especially where publicity/anonymity consequences are a core concern.

4) Complex Concepts Simplified

  • “Aged out”: A person was a child when the alleged offence occurred, but becomes an adult (turns 18) before being brought through child-specific criminal procedures. The practical effect is loss of Children Act protections.
  • Constitutional right to trial with due expedition: The State must progress investigations and prosecutions without undue delay. Where the suspect is a child, courts recognise a heightened need for speed because delay can itself cause distinct harms (including loss of child procedures).
  • Section 75 (Children Act 2001): A procedure allowing the Children Court to decide whether certain indictable matters involving a child should nonetheless be dealt with summarily (a key “gateway” decision affecting forum and potential sentencing limits).
  • Prohibition (judicial review): An exceptional High Court remedy stopping a criminal prosecution from continuing. Even if delay is blameworthy, prohibition generally requires exceptional, serious prejudice.
  • Gilchrist-type order: A reporting restriction order used to prevent publication/broadcast of identifying material in appropriate cases, potentially mitigating the loss of statutory anonymity protections.

5) Conclusion

P.M. v The Director Of Public Prosecutions (Approved) [2026] IEHC 493 reinforces a stringent post-Doe/Brophy approach: even where prosecutorial delay is excessive and blameworthy in a child-to-adult transition case, prohibition will generally be refused unless the applicant demonstrates truly exceptional prejudice beyond the ordinary consequences of having aged out. The Court accepted that comparator co-accused outcomes could support a reasonable possibility of a lost s. 75 benefit, but held that increased sentencing exposure—tempered by the Circuit Court’s duty of proportional, individualised sentencing—did not justify halting a prosecution for serious alleged public-order violence. The judgment also points toward reporting-restriction mitigation as a practical remedy where loss of Children Act anonymity is implicated.
