M. v The Director Of Public Prosecutions (Approved) (Rev1)

High Court of Ireland
Feb 19, 2026
Smart Summary (Beta)

Summary of Judgment — Judicial Review

Factual and Procedural Background

The Applicant faces one count of sexual assault alleged to have occurred on 15 November 2008. The Complainant was a friend of the Applicant's wife and a bridesmaid at the Applicant's wedding. The alleged assault is said to have occurred during an overnight visit at the Applicant's three-bedroom apartment when the Applicant had gone to bed intoxicated and the Complainant later awoke to the assault. Contemporaneous email exchanges of 27 November 2008 include apologetic/acknowledging statements from the Applicant.

The Complainant disclosed the incident to friends within days but made no police complaint until May 2016. The Police undertook initial investigative steps in 2016, but further progress was delayed; the investigation was reactivated and the Applicant was interviewed in 2021 and 2022, charged following DPP directions in September 2024 and charged in November 2024. The Book of Evidence was served in December 2024. The Applicant sought urgent disclosure and, after further disclosure and correspondence, filed a judicial review application on 11 March 2025; leave to proceed was granted by Judge Simons on 7 April 2025. Judge Phelan delivered judgment on 19 February 2026. An anonymity order made ex parte at leave stage continuing prohibition on identifying the Applicant and the Complainant was maintained.

Legal Issues Presented

  1. Whether the combined complainant and prosecutorial delay creates a real or serious risk that the Applicant will not receive a fair trial that cannot be cured by the trial judge.
  2. Whether any prosecutorial delay was blameworthy or unexplained and, if so, whether the public interest in prosecution is outweighed by the Applicant's right to an expeditious trial (the P.M. balancing exercise).
  3. Whether wholly exceptional circumstances exist such that, even absent an incurable risk of unfairness, the court should exercise its residual jurisdiction to prohibit the trial.

Arguments of the Parties

Applicant's Arguments

  • There was inordinate, excessive and unexplained delay (complainant delay to 2016 and prosecutorial/investigative delay through 2024) producing prejudice.
  • Prejudice includes deterioration of the Complainant's memory (fibromyalgia), faded or inconsistent witness recollection, lost investigative opportunities (2016–2021), and absence of specific contemporaneous records the defence might have used.
  • The Applicant's own serious medical and psychological deterioration (surgeries, immune thrombocytopaenia, anxiety, suicidal ideation) has been caused or materially exacerbated by the delay, rendering a fair trial impossible and breaching constitutional rights to due process and expedition.

Respondent's Arguments

  • The delays are explained and not culpable: complainant delay was outside Police control and investigative delay was due to operational pressures and prioritisation; once reassigned the investigation proceeded.
  • Alleged prejudice (memory issues, inconsistencies, missing evidence) is speculative and a matter for the trial judge; issues of credibility and memory are for trial testing.
  • Stress and anxiety claimed must be extraordinary and causally linked to delay to justify prohibition; they are not. Contemporaneous emails from 2008 including apologetic/acknowledging statements weigh against prohibition.

Table of Precedents Cited

Precedent Rule or Principle Cited For Application by the Court
P.M. v. Malone [2002] 2 I.R. 560 Recognition of constitutional right to trial with reasonable expedition and balancing public interest with expeditious trial. Applied as part of the balancing exercise where prosecutorial delay found; public interest weighed against Applicant's right to expedition.
S.H. v. DPP , [2006] 3 I.R. 575 Dominant test for prohibition: whether delay creates a real or serious risk of unfair trial; courts no longer inquire into reasons for complainant delay. Adopted: court assessed only whether delay created an incurable risk of unfairness and declined to investigate complainant delay reasons further where no incurable risk shown.
B.J. v. DPP [2003] 4 I.R. 525 Examples of presumptive and actual prejudice (loss of evidence, faded memory) and the standard for prohibition. Used to illustrate categories of prejudice and caution against prohibiting on presumptive prejudice alone post S.H.
J.O'C. v. DPP [2000] 3 I.R. 478 Precedent on death/unavailability of witnesses and prejudice by loss of contemporaneous evidence. Referred to when considering actual prejudice and availability of witnesses in this case (all witnesses available).
P.T. v. DPP [2008] 1 I.R. 701 Authority for exercising residual jurisdiction to prohibit trials in wholly exceptional circumstances (e.g., extreme age/ill-health). Distinguished: court found facts here far from exceptional circumstances in P.T. and declined to prohibit.
J.D Loss of medical/forensic/text/digital records as example of actual prejudice. Referenced as category of prejudice but Court found documentary evidence remained and no identified lost records.
M.O'H. v. DPP [2007] 3 I.R. 299 Examples of prejudice from loss of records and stress thresholds for prohibition. Invoked to show that ordinary memory fade is insufficient; court applied that principle here.
J.D. v. DPP [2007] IEHC 40 Faded memory alone not sufficient to prohibit unless it removes a defence or prevents testing credibility. Cited in support of the proposition that memory issues must be shown to remove defence; court found they could be tested at trial.
RB v. DPP [2019] IECA 48 Requirement that applicant prove on balance of probabilities that delay creates real risk of unfair trial. Applied: court required and found evidence insufficient to meet this onus.
AT v. DPP [2020] IECA 6 Standard for proving prejudice and inadvisability of pre-emptive prohibition. Referred to in framing the high bar for prohibition; court adhered to that standard.
Devoy v. DPP [2008] 4 I.R. 235 High threshold for prohibition even where prosecutorial delay is blameworthy. Applied in balancing: although prosecutorial delay found, prohibition rarely follows without incurable unfairness.
Glynn v. DPP, Unrep. Heslin J., 2021 Admissions or partial admissions are relevant factors in the balancing exercise. Applied: contemporaneous apologetic emails weighed against grant of relief.
Connolly v. DPP [2009] IEHC 526 Greater expedition required in old cases or where delay exacerbates stress/health concerns. Quoted to note heightened duty of expedition in aged/fragile cases; court nevertheless found case not exceptional.
McFarlane v. DPP [2008] IESC 7 Balancing public interest in prosecution against accused's right to expedition. Used to support need to balance interests where prosecutorial delay is established.
M.O.H. v. DPP [2018] IEHC 560 Consideration of additional distress caused by delay in balancing exercise. Invoked regarding assessment of Applicant's claimed distress in balance with public interest.
Cormack v. DPP [2009] 2 I.R. 208 Stress/anxiety must be more than predictable levels to ground prohibition. Applied: court found Applicant's stress did not meet the exceptional threshold causally linked to delay.
P.B. v. DPP Trial judge's powers to withdraw a case or make directions to protect fairness. Cited to support the conclusion that fairness is primarily for the trial judge to police.
C.C. v. DPP [2019] IESC 94 Reaffirming trial judge's primary role and exceptional nature of prohibition relief. Relied upon in concluding prohibition should be refused where trial judge can safeguard fairness.
Nash v. DPP [2015] IESC 32 Illustration of factors relevant to assessing delay and prejudice. Referred to as part of the broader jurisprudence emphasising exceptionalism of prohibition.
M.S. v. DPP [2021] IECA 193 Example where cumulative circumstances (age, health, prosecutorial delay) justified prohibition. Distinguished: court held present facts fall well short of the exceptional combination in M.S.

Court's Reasoning and Analysis

Judge Phelan set out established jurisprudential principles: the Applicant must show a real or serious risk of an incurably unfair trial caused by delay, or else demonstrate wholly exceptional circumstances warranting prohibition. The court applied S.H. v. DPP to limit inquiry into complainant delay where no incurable unfairness is established and applied P.M. v. Malone to conduct a balancing exercise where prosecutorial delay was blameworthy.

The court found the 16-year interval between events and charge to be significant. It admitted and considered up-to-date medical evidence from the Applicant's GP. The court nevertheless concluded: (a) all primary witnesses remain alive and available; (b) contemporaneous documentary material (emails and messaging from November 2008) exists and undermines claims of lost documentary evidence; (c) alleged inconsistencies and faded memory are speculative and capable of being tested at trial; (d) the Applicant failed to identify specific missing evidence or witnesses made unavailable by delay; (e) the Applicant's claimed health and psychological deterioration, while real, was insufficiently shown to be causally linked to the delay such that it would prevent effective participation in a trial; and (f) contemporaneous apologetic emails constitute material to be weighed and caution against pre-emptive prohibition.

The court found investigative/prosecutorial delay (2016–2024) to be excessive and that reassignment should have occurred earlier, concluding that part of the delay was blameworthy. Having so found, the court proceeded to balance the public interest in prosecuting serious sexual offences against the Applicant's right to expedition and any exceptional personal circumstances. On that balancing, and given the available documentary evidence, witness availability and trial judge's ability to manage fairness, the court concluded that the Applicant had not met the high threshold for prohibition.

Holding and Implications

RELIEF REFUSED

Holding: The application for prohibition (or interlocutory injunction halting the criminal process) was refused. The court held that the Applicant did not establish a real and incurable risk of an unfair trial nor wholly exceptional circumstances warranting prohibition, although some prosecutorial delay was identified.

Implications: The criminal prosecution may proceed to trial. The trial judge is tasked with safeguarding fairness during the trial and may give directions, withdraw the case from the jury if necessary, or take other measures should unfairness materialise. No new precedent was established; the decision applies established authorities and confirms the exceptional nature of prohibition relief.
