Sutton v Director of Public Prosecutions & Ors [2025] IEHC 375: Clarifying the Non-Applicability of “Date of Knowledge” and Reinforcing the One-Proceeding Rule in Criminal Judicial Review

Introduction

In Sutton v Director of Public Prosecutions & Ors [No. 2], the High Court (Gearty J) confronted a repeated attempt by a criminal accused to prohibit a retrial for assault causing harm. The Applicant, Mr Sidney Sutton, had already failed in:

• an appeal against an order for retrial (Court of Appeal & Supreme Court), and
• a first set of judicial-review proceedings to stop that retrial.

Undeterred, he launched a second judicial-review application, this time asserting “new evidence” derived from a 999 emergency call, alleged non-disclosure of forensic reports, and arguments about uncorroborated statements.

The judgment is important because it definitively rules that evidence already disclosed in a Book of Evidence cannot be characterised as new merely because an accused later chooses to examine it, and it re-affirms that Henderson v Henderson abuse-of-process principles apply with full rigour to criminal judicial reviews.

Summary of the Judgment

• The application for leave to seek judicial review was refused in its entirety.
• The Court held that:
  • The 999 recording had been in the Applicant’s possession since 2020; it is therefore not “new evidence”.
  • Arguments about unlawful entry, lack of forensic reports, or corroboration are matters for the trial court, not for judicial review.
  • All issues either were or could have been raised in the first judicial-review proceedings; Henderson principles bar re-litigation.
  • No arguable case of mala fides, constitutional wrong, or denial of fair trial was established.
• No stay of the retrial was granted; the criminal proceedings may proceed.

Analysis

1. Precedents Cited

a) Henderson v Henderson (1843) 3 Hare 100

• Establishes the doctrine that parties must advance their whole case at once; it prevents successive litigation on matters that were, or could have been, raised earlier.
• Applied by Gearty J to hold that Sutton’s second application constituted an abuse of process.

b) A.A. v Medical Council [2003] IESC 70

• Adopts and modernises the Henderson principle for Irish jurisprudence.
• Relied upon to reinforce that judicial-review applicants cannot circumvent final decisions by repackaging old complaints as “new”.

c) The People (DPP) v J.C. [2015] IESC 31

• Addresses exclusion of unconstitutionally obtained evidence (so-called “J.C. test”).
• Mentioned by the Applicant but held by the Court to be a matter for the Circuit Court trial judge, not for High Court prohibition.

d) Criminal Procedure Act 1967, s.4E

• Empowers a trial court to dismiss charges where evidence is insufficient.
• A Circuit Court judge had recently refused a s.4E dismissal; Gearty J regarded that decision as non-justiciable in judicial review absent exceptional circumstances.

2. Legal Reasoning

The Court’s reasoning unfolds in three inter-locking steps:

1. No “new” evidence on the facts.
   • The 999 recording was part of disclosure in 2020. Merely listening to it in 2025 does not reset time.
   • Adopting a “date of knowledge” formula would incentivise deliberate ignorance and destabilise criminal procedure.
2. Henderson Abuse-of-Process.
   • All current arguments either were or could have been made in 2023/24 proceedings; therefore leave must be refused.
   • The principle promotes finality, judicial economy, and fair treatment of opposing parties.
3. Subsidiarity to the Trial Process.
   • Questions of unlawful entry, weight of evidence, or corroboration are quintessentially trial matters.
   • High Court prohibition jurisdiction is reserved for fundamental defects rendering a trial impossible; none existed here.

3. Potential Impact

• Criminal Defence Strategy: Accused persons and counsel must scrutinise disclosure promptly; failure to do so will not convert old material into “new evidence” for further judicial reviews.
• Judicial Resource Management: The judgment arms courts with clear language to summarily dismiss repetitive prohibition applications, preserving scarce judicial time.
• Clarification on “Date of Knowledge”: The concept—useful in civil limitation periods—has no foothold in criminal disclosure. Expect future courts to cite Sutton when similar arguments arise.
• Trial-Level Autonomy: Re-asserts that evidential rulings (unlawful entry, admissibility, corroboration) belong to the trial judge, reinforcing the separation between judicial review and trial jurisdiction.

Complex Concepts Simplified

• Judicial Review vs. Appeal: Judicial review looks at how a decision was made (legality, fairness), not whether it was right. An appeal re-examines the merits. Sutton tried to use judicial review to revisit merits—impermissible.
• Prohibition Order: A court order preventing a lower court from continuing proceedings. Granted only for grave irregularities (e.g., bias) that would make a trial inherently unfair.
• Henderson Principle: Think of it as a one-bite rule—litigants get one shot to present all arguments about a matter. No serial bites at the same cherry.
• Date of Knowledge (civil context): In civil limitation statutes, the clock may start when a plaintiff first learns of an injury. Sutton tried to import this idea to criminal disclosure, but the Court said it does not apply.
• Corroboration: Independent evidence that supports a witness’s testimony. Modern Irish law allows convictions without corroboration unless specifically required (e.g., accomplice evidence rules—now rare).

Conclusion

Sutton (No. 2) adds a significant layer of clarity to Irish criminal procedure. It firmly states that:

“Material served in the Book of Evidence is not ‘new’ merely because an accused only later chooses to examine it, and the doctrine of Henderson v Henderson bars successive judicial-review applications recycling old issues.”

By anchoring its decision in well-established authority while explicitly rejecting a “date-of-knowledge” workaround, the High Court strengthens finality, promotes diligent engagement with disclosure, and respects the constitutional role of the trial court. Future litigants will find it considerably harder to relitigate prohibition applications once their arguments have been—or could have been—ventilated. The judgment therefore stands as a key precedent on the boundaries of criminal judicial review in Ireland.
