Background
The applicant, G.D. (anonymised on account of disclosed medical and mental health matters), faced 49 counts of fraud under the Criminal Justice (Theft and Fraud Offences) Act 2001. The charges alleged that between December 2016 and October 2017 he presented false instruments to KBC Bank and Permanent TSB in order to induce those institutions to make loans. A book of evidence was served in December 2021, and the case was listed for trial in the Circuit Criminal Court. In July 2025, the presiding Circuit judge refused the applicant’s application for a permanent stay of proceedings, having considered complaints about disclosure, the loss of CCTV footage, and alleged prosecutorial delay. The applicant, who was self-represented, then sought judicial review in the High Court, seeking an order of prohibition permanently restraining the prosecution, certiorari of the Circuit judge’s ruling, and interim stays on all further steps in the proceedings.
The applicant’s grounds fell under four broad headings: a continuing failure by the prosecution to make proper disclosure; prosecutorial delay; a failure by investigating Gardaí to seek out and preserve CCTV evidence in a timely manner; and an alleged irrationality in the Circuit judge’s refusal to stay proceedings. At the hearing, the applicant also brought a late motion seeking to amend his statement of grounds to add a complaint that the State Solicitor, who had previously acted for him in minor unrelated proceedings in 2018, held confidential information that undermined the fairness of the forthcoming trial.
The respondent DPP opposed the application on the merits and additionally argued that the judicial review was premature, contending that all matters raised were best left to the court of trial to address, and that no exceptional circumstances existed to justify an order of prohibition.
The Court’s Holding
Mr. Justice O’Donnell refused all relief sought. The court first refused the amendment application, applying the three-part test from B.W. v. Refugee Appeals Tribunal [2015] IEHC 725: the point must be arguable, there must be an explanation for not having pleaded it earlier, and the opposing party must not be irremediably prejudiced. The court found all three limbs unsatisfied. The State Solicitor had averred he had no recollection of the applicant from the minor prior proceedings, which the court accepted as entirely reasonable given the routine nature of such matters. The applicant had no credible explanation for raising the point at the eleventh hour, particularly given that he had been legally represented at several earlier stages when the solicitor was already visibly on record for the prosecution. Allowing the amendment would also have nullified the respondent’s entire affidavit evidence, causing clear and irremediable prejudice.
On the substantive application, the court applied the settled principle, confirmed by the Supreme Court in Byrne v. DPP [2011] 1 I.R. 346 and DPP v. CC [2019] IESC 94, that the court of trial is the primary and most appropriate forum to vindicate an accused’s right to a fair trial. Judicial review and an order of prohibition will only be warranted in truly exceptional cases where there is a demonstrated real risk of an unfair trial that the trial court itself could not adequately remedy. The modern jurisprudence, reinforced by the Court of Appeal in X. v. DPP [2020] IECA 4 and A.T. v. DPP [2020] IECA 6, makes clear that complaints about delay, missing evidence, and disclosure deficiencies are quintessentially matters for the trial judge to manage, with an appellate safety net thereafter. The court was satisfied that the trial judge would be well placed to ensure a fair trial and that no exceptional circumstances bringing this case outside the ordinary run had been established.
Key Takeaways
- The High Court will intervene by way of prohibition only in exceptional cases; the threshold is high and the mere existence of disclosure complaints or missing evidence does not suffice to clear it.
- A late application to amend judicial review grounds will fail where the applicant has no arguable point, offers no satisfactory explanation for the delay in raising the issue, and the amendment would irremediably prejudice the opposing party by invalidating its existing evidence.
- The court of trial — and on appeal the appellate courts — remains the constitutionally appropriate forum for vindicating fair-trial rights; the High Court’s supervisory role on judicial review is residual and exceptional.
- Self-representation does not lower the procedural threshold, but the court may grant anonymity where sensitive medical or mental health material has been disclosed in the proceedings.
Why It Matters
This judgment is a clear restatement of the restrictive modern approach to pre-trial prohibition applications in Irish criminal law. Following the Supreme Court’s guidance in DPP v. CC [2019] IESC 94 and the Court of Appeal decisions of 2020, the High Court continues to resist early-stage judicial review of prosecutorial decisions, channelling fair-trial complaints towards the trial process itself. Practitioners advising accused persons who face disclosure failures or alleged investigative misconduct should understand that the prospects of securing a prohibition by way of judicial review are narrow; the better strategy is ordinarily to raise these complaints before the trial judge at first instance and, if necessary, on appeal.
The judgment also provides useful guidance on the amendment of judicial review grounds in the criminal context, confirming that an eleventh-hour attempt to introduce a conflict-of-interest complaint against the State Solicitor — where the solicitor has no memory of the earlier minor proceedings and the accused was represented at multiple prior hearings — will not be permitted where it would derail the entire evidential framework already before the court.
