Criminal Judicial Review: Short Delays Require Justification and Collateral Disputes Must Engage Trial Fairness

Decision: Morrissey Junior v The Director Of Public Prosecutions and Ors (Approved) [2026] IEHC 633

Court: High Court of Ireland
Judge: Mr Justice Barry O'Donnell
Delivered: 18 September 2026

1. Introduction

This judgment addresses two recurring issues in criminal judicial review: the explanation required for commencing proceedings outside the prescribed time limit, and the distinction between a genuinely unfair trial and disagreement with a trial judge’s assessment of evidence.

The applicant sought to quash an assault conviction upheld by Carlow Circuit Court. He alleged unfairness in the refusal of an adjournment, failures to obtain witness statements, errors concerning a prosecution witness’s credibility, and inadequate investigation of related complaints. He also sought declarations that his trial infringed Article 38.1 of the Constitution and Article 6 of the European Convention on Human Rights.

The High Court refused relief on two independent grounds. First, the proceedings were five days late and the applicant had not adequately explained the delay. Second, even if time had been extended, the complaints did not establish an unfair trial or another proper basis for judicial review.

The decision principally applies established law rather than creating a new test. Its significance lies in its insistence that a short delay still requires justification, while complaints about missing evidence or collateral wrongdoing must be connected to the fairness of the criminal proceedings under challenge.

2. Background and Procedural History

The underlying dispute

The prosecution arose against the background of a dispute over land associated with Dan Morrissey (Irl) Limited, a family business placed in receivership. The applicant maintained that employment arrangements entitled him to ownership of certain property, including his family home. His challenge to an eviction order had been unsuccessful.

In January 2018, confrontations occurred when others entered the disputed lands. Those events resulted in public order convictions, appeals against which remained outstanding. Neither those convictions nor the legality of the eviction was before the High Court in this application.

The alleged assault

The relevant incident occurred on 19 April 2018. The applicant approached a security contractor who was in a vehicle at the site. According to the contractor, the applicant acted aggressively, used a powerful lamp to disorient him, threatened to shoot him, and was accompanied by agitated dogs. The applicant disputed the account.

A substantial part of the applicant’s subsequent defence concerned how the contractor had reached the site. The contractor was disqualified from driving and maintained that his wife had brought him there. The applicant alleged that the contractor had driven himself and argued that this undermined his credibility and supplied an alternative explanation for his behaviour when Gardaí arrived.

The proceedings under challenge

The applicant was convicted in the District Court of assault contrary to section 2 of the Non-Fatal Offences Against the Person Act 1997. The conviction was upheld by Carlow Circuit Court on 14 March 2024.

Before the Circuit Court hearing, the applicant had experienced difficulties obtaining his file from a former solicitor. However, by the hearing he had both solicitor and counsel, and counsel indicated that the case was ready to proceed. An adjournment sought approximately an hour into the hearing was refused.

The statement of grounds for judicial review was filed on 19 June 2024. The High Court treated this as five days outside the applicable three-month period.

3. Summary of the Judgment

  • No extension of time: The applicant supplied no satisfactory affidavit explanation for the delay. Its short duration did not dispense with that requirement.
  • No unfair refusal of an adjournment: The trial judge acted within a broad discretion. The defence had announced its readiness, disclosure had previously been furnished, and no cogent explanation established why the former solicitor’s file was necessary before proceeding.
  • No basis for a retrospective evidential challenge: Evidence said to be prejudicial had not been challenged at trial, and the High Court found no reason to intervene afterwards.
  • No established breach concerning missing statements: The investigative duty was not absolute, the potential witnesses remained available, and procedural means existed to secure their attendance.
  • No reviewable error concerning credibility: The trial judge could accept the contractor’s account of the assault even if the allegation of disqualified driving were assumed to be correct.
  • No sufficient connection between other investigative complaints and trial unfairness: Judicial review could not be used to repackage disagreement with the Circuit Court’s findings.

The conviction was therefore left undisturbed. The judge provisionally considered that the successful respondent should receive costs, subject to any dispute being addressed when final orders were considered on 13 October 2026.

4. Analysis: Legal Reasoning and Precedents Cited

4.1 Judicial review is not another appeal

The starting point was the limited supervisory function of judicial review. Relying on Connor v. DPP [2022] IEHC 176, the court emphasised that the High Court does not reassess a criminal case as an appellate court would.

That authority reproduced the traditional statement, approved in Lennon v. District Judge Clifford [1992] 1 I.R. 382, distinguishing errors made within jurisdiction from an excess or abuse of jurisdiction. Where a court has authority to decide the matter, disagreement with its factual conclusions or legal reasoning does not automatically justify certiorari.

This distinction framed the entire judgment. The applicant’s objections frequently returned to whether the contractor should have been believed and whether more weight should have been attached to alleged disqualified driving. Those were matters the Circuit Court had considered. Judicial review did not provide an opportunity to have them weighed again.

The principle is not that criminal decisions are immune from review. Jurisdictional defects and breaches of fair procedures remain reviewable. Rather, an applicant must identify such a defect instead of merely asserting that the trial court reached the wrong conclusion.

4.2 A five-day delay still required an evidenced explanation

Order 84, rule 21(1) of the Rules of the Superior Courts requires an application for leave to seek judicial review within three months. Under rule 21(2), where a court order is challenged, time runs from the date of that order. Rule 21(3) provides the jurisdiction to extend time.

The applicant expressly requested an extension if necessary, but neither his pleadings nor affidavits explained why he had failed to apply within time. His written submissions likewise did not engage with the issue. Only at the hearing did he argue that the delay was minimal and that changes to the procedure for stopping time supplied a sufficient reason.

The governing authorities

In M. O'S. v. Residential Institution Redress Board [2018] IESC 61, the Supreme Court explained that extending time involves a discretionary assessment in the interests of justice. Applicants must explain both the initial failure to act within time and any subsequent period before bringing the application. The court must assess whether the reasons objectively justify the delay, while considering the wider circumstances and effects on other parties.

The High Court stressed that this approach rejects rigid, absolute rules. The reference within that authority to De Roiste reinforced the proposition that exercising discretion requires a balancing of relevant factors, rather than applying an inflexible formula.

Nevertheless, contextual flexibility does not eliminate the need for an explanation. The exceptional circumstances in M. O'S. v. Residential Institution Redress Board included the vulnerability of survivors of institutional abuse, an overwhelmingly strong underlying case, and a significant change in legal interpretation affecting the prospects of proceedings.

By contrast, DPP v. Tyndall [2021] IEHC 283 refused an extension where the explanations were perfunctory. That case also recognised the importance of criminal finality: an accused person was entitled to organise her affairs on the basis that the proceedings had concluded. The present judgment drew from it the broader lesson that reasons for delay must be evaluated in context, and that the apparent strength of a claim will rarely justify an extension by itself.

Application to this case

The applicant’s reliance on procedural changes did not explain his default. Under the former procedure, he would still have needed to make a timely “stop the clock” application. Under the revised procedure, filing the necessary documents was sufficient—a practical simplification rather than a demonstrated obstacle.

The court also found no unusual complexity, uncertainty about the relevant date, or other feature warranting an extension despite the deficient explanation. The applicant had legal representation during the relevant proceedings.

The important distinction is between the length of delay and its justification. Five days was relatively little, but saying that the delay was short did not explain why it occurred. Equally, the judgment does not establish that a five-day delay must always be fatal: refusal followed from the absence of adequate reasons and the surrounding circumstances.

4.3 Refusing an adjournment did not make the trial unfair

The applicant relied on O'Callaghan v. District Court Clifford [1993] 3 I.R. 603 for the proposition that refusing an adjournment can infringe constitutional rights where an accused has no meaningful opportunity to consult counsel.

He also invoked Connors v DPP [2023] IEHC 8. In that case, relief followed where counsel had no opportunity to consult the accused before a sentencing hearing, the adjournment request was made in good time, and an adjournment would not materially disrupt the court’s list.

The High Court distinguished those circumstances. Here:

  • the applicant had solicitor and counsel at the Circuit Court hearing;
  • counsel expressly indicated at the outset that the matter was ready to proceed;
  • disclosure had been supplied directly to the applicant in September 2023 and January 2024;
  • the later application did not identify how missing material from the former solicitor’s file impaired the defence; and
  • the intervening development was the prosecution’s withdrawal of a disputed additional charge, rather than an obvious new obstacle to a fair hearing.

The applicable restraint was supported by F.M. v DPP [2022] IECA 79. An adjournment is essentially a judgment call, reviewable where it exceeds jurisdiction, is irrational, or rests on improper or irrelevant considerations. The High Court found no such defect.

Establishing unfairness is different from proving a different outcome

The court accepted the principle in Connors v DPP that, once a breach of fair procedures is established, an applicant need not demonstrate that the result would otherwise have been different.

That did not remove the anterior obligation to show why the procedure was unfair. Examining the absence of a cogent reason for the adjournment was not an improper demand for proof of a different verdict. It was part of deciding whether the refusal had infringed fair procedures at all.

This distinction is central: procedural rights do not depend on proving that an accused would have won, but an applicant must still identify the procedural entitlement that was denied.

4.4 Evidence should ordinarily be challenged when it is introduced

The applicant also complained about evidence concerning public order matters that had been introduced during the hearing. The respondent relied on People (DPP) v. Cronin (No 2) [2006] 4 I.R. 329, which deprecated retrospective challenges to matters not contested at trial.

Brassil v. DPP [2021] IECA 83 supplied an important qualification: failure to object contemporaneously is relevant, but does not automatically bar a later challenge.

The High Court treated the applicant’s argument as an after-the-event objection and found no basis for interfering. Its reasoning preserves a practical principle without turning it into an absolute waiver rule. Trial objections allow the judge to address a perceived problem immediately; a later challenge must account for the fact that this opportunity was not used.

4.5 Investigative duties are important, but not unlimited

The applicant argued that statements should have been obtained from the contractor’s wife and father-in-law to test his account of travelling to the site. Without prior statements, he maintained, he could not safely predict their evidence or use inconsistencies to challenge them.

He relied on DPP v. S.Q. [2023] IESC 8, particularly its explanation that the Garda duty to seek evidence helps redress the imbalance between prosecution and defence.

The High Court rejected the proposed interpretation that this authority established a heightened duty whenever a request came from an unrepresented person. The cited passage concerned the duty to seek both inculpatory and exculpatory evidence: evidence pointing towards guilt and evidence assisting the defence.

Importantly, the court did not determine that a self-represented suspect could never attract additional investigative obligations. It expressly considered this an unsuitable case to decide that broader question, especially because the applicant was represented at the Circuit Court hearing and in the judicial review.

The evidence had not become unavailable

The potential witnesses had not disappeared, and their evidence had not been destroyed. The applicant’s legal representatives could seek statements or secure attendance through witness summonses. The respondent also identified the court’s power, in appropriate circumstances, to call a witness for questioning by both parties.

The court therefore distinguished a failure by investigators to obtain a statement from a situation in which the defence has actually lost access to material evidence. It did not impose a general obligation on the prosecution to pursue every evidential route requested by an accused.

4.6 Collateral wrongdoing did not determine credibility or guilt

The applicant’s central credibility argument was that the contractor had driven while disqualified and had misrepresented how he arrived. The Circuit Court had considered this issue and remained willing to accept his evidence about the assault even if the driving allegation were accepted.

The High Court held that the trial judge was entitled to take that approach. Evidence of possible wrongdoing on another issue does not automatically render a witness’s entire account unworthy of belief. Its relevance and weight remain matters for the trial court, subject to proper legal limits.

The applicant also challenged the Circuit Court’s treatment of whether the site was a public place, the relevance of intention to disqualified driving, and the use of the balance of probabilities. The respondent answered that the contractor was not on trial and that the applicant’s guilt, unlike the collateral driving issue, had to be established beyond reasonable doubt.

The High Court ultimately found no error warranting relief. The judgment should not, however, be read as independently deciding that the contractor had committed no driving offence or as prescribing a universal standard of proof for every collateral issue in criminal proceedings. Its narrower conclusion was that the trial judge could accept the assault evidence notwithstanding the asserted driving misconduct.

4.7 Other investigative complaints lacked a demonstrated connection to trial fairness

The applicant referred to failures to investigate alleged trespass, forcible entry, damaged locks and the January confrontation. He also sought Garda statements concerning the lawfulness of his arrest.

The respondent relied on DPP v. Doyle [2020] IEHC 120 to support the argument that the applicant had identified no investigative shortcoming depriving him of the ability to advance an issue material to his defence. The High Court agreed with the substance of that objection: the applicant’s legal argument did not connect the alleged omissions to unfairness in the assault trial.

The respondent’s arrest argument was similarly based on the absence of a causal connection between any alleged illegality and the proceedings under challenge. The judgment does not establish that arrest legality is invariably irrelevant; rather, no material connection was demonstrated here.

Finally, O'Mahoney v. Hughes [2018] IECA 264 was cited against presenting disagreement with trial findings as a public-law challenge. The High Court accepted that characterisation of the application. The broad history of disputes did not itself establish a defect in the particular conviction being reviewed.

5. Potential Impact

Time-extension applications require preparation, not assumptions

The decision warns practitioners against assuming that a brief default will be overlooked. A request for an extension should explain the relevant chronology on affidavit and address why the reasons justify the court’s discretion. Merely requesting an extension in the statement of grounds is insufficient.

Fair-trial claims must identify the procedural problem

Future applicants challenging adjournment refusals will need to distinguish genuine inability to prepare or consult from an unsupported preference for more time. Counsel’s recorded readiness to proceed, the availability of disclosure, and the timing of the request may be particularly important.

Investigative complaints must be assessed concretely

The judgment encourages attention to what evidence was omitted, whether it remains obtainable, what issue it could illuminate, and how the omission affects a fair defence. It does not license investigators to disregard potentially exculpatory material.

Credibility findings remain primarily for the trial court

The decision reinforces the boundary between trial assessment and supervisory review. Possible misconduct by a witness may be relevant, but does not compel wholesale rejection of the witness’s evidence or establish that the accused was tried unfairly.

Its broader significance is therefore one of disciplined legal analysis: neither procedural default nor an asserted investigative deficiency can be resolved solely by labels. Each requires a properly evidenced connection to the applicable legal test.

6. Complex Concepts Simplified

Certiorari
An order quashing a decision because of a legally reviewable defect. It is not simply a second assessment of whether the decision was correct.
Judicial review and appeal
An appeal may reconsider the merits within its governing rules. Judicial review principally supervises legality, jurisdiction and procedural fairness.
Jurisdiction
The legal authority to hear and decide a matter. A disputed conclusion reached while exercising that authority is not automatically an excess of jurisdiction.
Collateral issue
A secondary matter, such as a witness’s alleged driving offence, rather than the central question of whether the accused committed the charged assault.
Inculpatory and exculpatory evidence
Evidence supporting guilt and evidence supporting the defence. Investigative duties extend to both categories.
Actual prejudice
A demonstrated adverse effect. Once a breach of fair procedures is established, an applicant need not prove that a different procedure would have produced an acquittal. The breach itself must nevertheless be established.
Ex post facto challenge
An objection raised afterwards rather than when the disputed evidence or procedure could have been addressed at trial.

7. Conclusion

The High Court refused relief because the applicant neither justified his late application nor established unfairness in the Circuit Court trial. These were independent reasons for dismissal.

The judgment reinforces three practical principles: short delays still require proper explanation; fair-procedure claims must identify an actual procedural deficiency without needing to prove a different verdict; and judicial review cannot become a further appeal against credibility findings or collateral factual conclusions.
