Criminal Case Materials May Be Released to Assist a Public Inquiry Where Justice Requires and No Legal Prejudice Arises

1. Introduction

This judgment confirms that the High Court’s inherent jurisdiction to secure the administration of justice can support the release of criminal prosecution materials for use by a public inquiry outside Ireland. Importantly, that power is not confined to judgments or statements delivered publicly in court: it can extend to books of evidence, trial transcripts and other relevant evidential material.

The Minister for Justice, Home Affairs and Migration sought orders requiring the Director of Public Prosecutions (“DPP”) and the Registrar of the Special Criminal Court to provide documents for onward transmission to the Omagh Bombing Inquiry. The applications concerned five individuals prosecuted before the Special Criminal Court in connection with dissident terrorism around 1997–1998.

The central question was whether facilitating the Inquiry constituted “doing justice” for the purposes of the court’s inherent jurisdiction, notwithstanding that the documents were not sought for conventional litigation. The court answered that question affirmatively, while treating the absence of legal prejudice as an essential safeguard.

The decision develops an earlier order concerning the same Inquiry. Its particular significance lies in applying the established jurisdiction to a wider range of prosecution materials and in recognising that the interests of justice can encompass the work of a public inquiry addressing a historic atrocity.

2. Background and Procedural Context

The Inquiry and Ireland’s cooperation

The Omagh Bombing Inquiry was established under the United Kingdom’s Inquiries Act 2005 and is chaired by Lord Turnbull. Its task is to determine whether the bombing in Omagh on 15 August 1998, in which 29 people and two unborn children were killed, could have been prevented by United Kingdom state authorities. Its terms of reference give particular attention to matters considered by Mr Justice Horner in earlier judicial review proceedings.

The Irish Government formally decided in July 2024 to assist the Inquiry. A Memorandum of Understanding between the Minister and the Inquiry’s Chair, dated 15 April 2025, subsequently set out arrangements for cooperation.

That framework was strengthened by the International Co-Operation (Omagh Bombing Inquiry) Act 2026. The Act provides a statutory system of cooperation, including arrangements for evidence to be given in Ireland to a nominated judge for the Inquiry’s purposes. The present applications nevertheless sought relief under the court’s inherent jurisdiction. The court treated the legislation as reinforcing the public interest in assistance, rather than identifying it as the direct source of the production orders.

The three applications

The requested documents included books of evidence, transcripts, rulings and miscellaneous evidential materials identified in schedules to the special summonses. The proceedings were divided as follows:

The applications were supported by affidavits from a Principal Officer in the Department of Justice, Home Affairs and Migration. Neither the DPP nor the Registrar opposed production, although the Registrar identified possible practical difficulties in locating all the documents.

3. Summary of the Judgment and Orders

The High Court held that providing the requested materials would serve the administration of justice by assisting the Inquiry’s work. It was satisfied that production would cause no legal prejudice to any party in the applications determined on 28 August.

The court therefore ordered the DPP and the Registrar to provide the Minister with copies of the scheduled materials in proceedings 2026 167 SP and 2026 169 SP. It expressly recognised that production could occur in phases and that logistical difficulties might arise.

The court also directed Gwen Malone Stenography Services to assist by releasing master transcripts, in an appropriate format, to the Registrar where the service held transcripts that the Registrar did not possess. There was no order as to costs, and general liberty to apply was granted.

The remaining application was adjourned so that the Chief State Solicitor’s Office could write by registered post to the individual resident in Northern Ireland. The correspondence was to include the special summons and grounding affidavit, identify the adjourned hearing date and explain the orders made in the other proceedings.

The postscript records that the required letter was sent on 28 August. No appearance was made, either personally or remotely, at the resumed hearing on 4 September. The court then made equivalent orders concerning the book of evidence and transcripts relating to the Special Criminal Court trial that had ended on 26 February 2004.

4. Precedents Cited and Their Influence

Minister for Justice v DPP & Anor [2025] IEHC 771

This earlier decision provided the immediate foundation for the applications. In May 2025, the same judge had directed production of Special Criminal Court judgments and transcripts of sentencing remarks for transmission to the Omagh Bombing Inquiry.

The earlier materials were confined to judgments and remarks delivered in open court. The present applications went further by seeking books of evidence and other evidential documents. The court therefore had to consider whether the reasoning supporting the earlier order also justified access to materials beyond publicly delivered judicial statements.

The earlier judgment had already recognised that assisting the Inquiry was a substantial public interest and that “doing justice” could extend beyond existing litigation. It also acknowledged the Inquiry’s importance to victims and survivors and its contribution to addressing the legacy of the past. Those considerations remained applicable, with additional support from the enactment of the 2026 Act.

Breslin v McKenna [2009] 1 I.R. 298

This was the controlling authority. It concerned requests for Special Criminal Court transcripts and books of evidence for use in civil proceedings in Northern Ireland, involving some of the same prosecutions as the present applications. A majority of the Supreme Court held that both categories of document should be produced.

As explained in the present judgment, Geoghegan J’s majority reasoning grounded the jurisdiction in the courts’ responsibility for the administration of justice. The relevant principles were:

• There is no prohibition on providing transcripts or books of evidence where their provision is necessary for doing justice.
• Production must not cause legal prejudice to another party.
• Where a court in another jurisdiction has found documents necessary for proceedings there, Irish courts should ordinarily accept that finding unless production could lead to a fundamental injustice.

The express treatment of books of evidence in Breslin v McKenna was decisive. It demonstrated that the jurisdiction was not restricted to judgments or public judicial remarks and supported the broader production sought here.

There was, however, an important distinction: Breslin v McKenna concerned civil litigation, whereas the present requests served a public inquiry. The High Court applied its underlying administration-of-justice rationale to the Inquiry. It did not suggest that an inquiry’s request was itself equivalent to a foreign court’s judicial finding of necessity.

Kelly v Ireland [1986] ILRM 318

The judgment notes that Geoghegan J approved certain dicta of O’Hanlon J in this case. Its significance here is therefore indirect: it forms part of the doctrinal foundation endorsed by the Supreme Court in Breslin v McKenna.

The High Court did not separately examine its facts or formulate an additional test from it. The operative principles were those drawn from the Supreme Court’s majority reasoning in Breslin v McKenna.

5. Analysis of the Court’s Reasoning

A. “Doing justice” is not confined to litigation

The central reasoning appears in the court’s acceptance that the interests of justice have a wider meaning than assisting existing legal proceedings. Providing materials to an inquiry investigating whether a devastating attack could have been prevented could constitute doing justice for those killed and for their families.

This does not convert the Inquiry into a court or give it a general entitlement to Irish criminal records. Rather, it identifies a purpose capable of justifying a judicial production order. The High Court remained responsible for deciding whether that purpose warranted release of the particular materials.

B. Public interest supported, but did not replace, judicial scrutiny

The Government decision, the Memorandum of Understanding and the 2026 Act demonstrated sustained State commitment to assisting the Inquiry. Together, they strengthened the public-interest justification for production.

Nevertheless, the court did not treat executive policy or legislation as automatically resolving the applications. It applied the principles governing its inherent jurisdiction and separately examined prejudice. The decision therefore preserves the distinction between governmental support for cooperation and judicial authority over the release of court-related materials.

C. The jurisdiction extends to books of evidence

The difference between the earlier application and the present proceedings was substantive. A judgment or sentencing remark is a judicial statement delivered publicly; a book of evidence is a prosecution compilation containing evidential material. The fact that the earlier order concerned public judicial statements did not, by itself, establish an entitlement to the wider documents.

The court resolved this issue through Breslin v McKenna, which expressly addressed both transcripts and books of evidence. The extension was therefore anchored in existing Supreme Court authority rather than in a newly asserted general disclosure power.

D. Absence of legal prejudice was essential

The DPP confirmed that she did not object and was not asserting potential prejudice to the individuals concerned. The Registrar likewise did not object, subject to practical retrieval issues. Those positions supported the applications, but the court also reached its own conclusion that no relevant prejudice would result.

The court emphasised that the materials were not being sought during an ongoing trial, or in circumstances where a forthcoming trial or retrial presented an identifiable risk of unfairness. Three individuals were deceased, and the judgment identified no apparent future criminal trial involving those concerned.

The possibility of future proceedings was nevertheless addressed. Following Breslin v McKenna, the court noted that any future trial judge would have to ensure a fair trial and protect defendants against prejudice resulting from production. That observation was not a finding that disclosure can never affect fairness; it recognised the continuing responsibility of a criminal court should such an issue arise.

E. Notice remained important despite non-opposition

The adjournment of the Northern Ireland-related application is a significant procedural feature. Although the substantive reasoning favoured production, the court did not determine that application before arranging notification of the affected individual.

Residence outside Ireland was therefore not treated as a sufficient reason to proceed without giving an opportunity to respond. The eventual order followed the directed correspondence and the absence of any appearance at the resumed hearing.

F. Practical obstacles were managed through the orders

The age and location of the records created possible retrieval difficulties. The court addressed those difficulties through phased production, assistance from the stenography service and liberty to apply. These provisions made the orders workable without treating administrative inconvenience as a reason to refuse otherwise justified relief.

6. Significance and Potential Impact

The judgment provides a clear example of the High Court using its inherent jurisdiction to assist a public inquiry outside Ireland. Its contribution is principally an application and development of existing authority, rather than the creation of an entirely new jurisdiction.

• Broader justice-related purposes: A qualifying purpose need not be confined to litigation. An inquiry’s work may serve the administration of justice, particularly where it addresses grave historic harm.
• Wider categories of material: Books of evidence and other relevant prosecution materials are not excluded merely because they differ from publicly delivered judgments.
• Continuing safeguards: Future applicants must still establish a sufficient justice-related basis and satisfy the court that production will not cause legal prejudice.
• Complementary statutory and inherent mechanisms: A legislative cooperation framework may strengthen the justification for assistance without being the specific legal basis of the order sought.
• Procedural fairness: Notice and an opportunity to respond remain important where living individuals may be affected.

The decision should not be read as making criminal prosecution files generally available to the public or as deciding that every request from an overseas inquiry must succeed. The orders concerned identified materials, an established public-interest purpose and circumstances in which the court found no legal prejudice. Different facts, particularly an ongoing prosecution or a concrete fairness concern, would require separate assessment.

Nor did the judgment determine whether the bombing could have been prevented or resolve the responsibility of any individual or authority. It concerned access to materials that would assist the Inquiry in performing its own task.

7. Complex Concepts Simplified

Inherent jurisdiction

A court’s power, arising from its judicial function, to take measures needed for the administration of justice. Here, it supported orders releasing specified criminal case materials.

Book of evidence

A prosecution compilation setting out the evidence proposed for a criminal case, typically including witness statements and documentary material. Its contents are not themselves findings of guilt.

Legal prejudice

Harm affecting a legally protected interest, such as the fairness of criminal proceedings. The court found no such harm from the production ordered here.

Special summons and grounding affidavit

The documents initiating and supporting the applications. The summons identified the relief sought, while the affidavit supplied the evidential basis.

Phased production

Providing records in stages as they are located and prepared, rather than requiring every document to be supplied at once.

Liberty to apply

Permission to return to court if questions or difficulties arise in implementing the orders.

8. Conclusion

The judgment confirms that assisting a public inquiry can fall within the administration of justice and justify the release of criminal case materials under the High Court’s inherent jurisdiction. Its particular importance is the extension of the earlier Omagh Inquiry production orders beyond judgments and sentencing remarks to books of evidence and other prosecution records.

The governing principle remains conditional: production must serve the interests of justice without causing legal prejudice. Judicial scrutiny, appropriate notice and practical arrangements for compliance were therefore integral to the result—not incidental to it.
