Summary of Judicial Opinion — High Court (Judicial Review)
Factual and Procedural Background
This judicial opinion concerns an application for directions about the manner in which confidential material relating to the identity of persons who made protected disclosures may be exhibited and used in the context of pending judicial review proceedings. The Applicant seeks judicial review challenging the decision of the Second Respondent (the office-holder responsible for protected disclosures) to transmit the Applicant's protected disclosure to the Secretary General of The Department. The Applicant alleges that the Secretary General was implicated in the alleged wrongdoing and that the Second Respondent should instead have accepted and investigated the report himself, thereby seeking relief including certiorari and mandamus.
The Second Respondent, in preparing his defence, stated that he had received eight disclosures from seven different reporting persons in January 2024 comprising overlapping allegations concerning three alleged wrongdoers (the Defence Forces, The Department and the First Respondent). The Second Respondent prepared an analysis (a table) of the reports and proposes to exhibit the related reports (redacted/anonymised) in an affidavit filed in defence of the proceedings to verify the decision-making processes leading to transmission of the Applicant's report to various recipients (including the Secretary General, the Medical Council and the Legal Services Regulatory Authority).
An affidavit in support of the Second Respondent's application for directions was sworn by Attorney Cahill on 11 September 2025. The matter was heard by Judge Jackson, who received submissions from counsel for the Second Respondent and oral submissions (limited in scope) from counsel for the Applicant and the First Respondent. The Applicant sought liberty to apply once the defence documentation (and proposed redactions/anonymisations) were made available; Judge Jackson granted that liberty.
Legal Issues Presented
- Whether the statutory duty of confidentiality imposed by section 16 of the Protected Disclosures Act 2014 (as amended) permits the Second Respondent to exhibit third-party protected disclosures in defence of judicial review proceedings when such material is redacted/anonymised.
- Whether the exceptions in section 16(2) (in particular paragraphs (a) and (c)) apply so that disclosure of redacted/anonymised protected disclosures is a necessary and proportionate step in the context of the court proceedings.
- What procedural safeguards and conditions (if any) the Court should impose when permitting the use of redacted/anonymised protected disclosure material in court documents (including service on affected reporting persons and any stay/standstill arrangements pending applications by those persons).
Arguments of the Parties
Second Respondent's Arguments
- The Second Respondent submitted that section 16 of the Protected Disclosures Act 2014 imposes a duty of confidentiality but contains legislatively recognised exceptions (including where disclosure is a necessary and proportionate obligation in the context of investigations or judicial proceedings and where disclosure is otherwise required by law).
- The related reports are necessary for the Second Respondent's defence: the Court should be able to see the context in which the decision to transmit the Applicant's report was made, including the existence of overlapping/template elements in a cohort of contemporaneous reports.
- The Second Respondent must be able to show how the format and content of the other reports legitimately influenced his assessment, recipient selection and understanding of template language in the Applicant's report (including the allegation concerning the Secretary General).
- The Second Respondent invoked a duty of candour to disclose information relevant to review of his decision-making; the Court ultimately determining the review must have access to all relevant material.
- On proportionality, the Second Respondent proposed redaction/anonymisation of identifying information of the other reporting persons, and proposed not to join those reporting persons as notice parties (to avoid delay), while making the redacted/anonymised material available to the parties' legal advisors (subject to further protective measures if required).
Applicant's and First Respondent's Arguments
The opinion does not contain a detailed account of the parties' legal arguments for the Applicant or the First Respondent; it records that their submissions were made orally and were necessarily curtailed because the proposed redactions/anonymisations had not been made available to them in full at the time of hearing.

Application by the Court |
| Portakabin Ltd & Portakabin (Ireland) v Google Ireland Ltd [2021] IEHC 446 |
Discussion of section 16 of the Protected Disclosures Act 2014 and the Act's protections for reporting persons, including prohibition on identifying a reporting person save in specified circumstances. |
The Court referred to this authority for the statutory context and the protective purpose of section 16 when assessing confidentiality obligations. |
| Wallace Smith Trust Co v Deloitte [1997] 1 WLR 257 |
Framework for when disclosure is "necessary" (litigious advantage, unavailability elsewhere, and non-oppressiveness), and the court's role in inspecting documents and mitigating confidentiality loss by redaction or limiting disclosure. |
The Court applied the Wallace Smith formulation to assess necessity, noting the need to ensure documents are genuinely required and that confidentiality loss can be mitigated. |
| Cooper Flynn v Radio Telefis Eireann [1993] 1 I.R. 375 |
Cited as approving the Wallace Smith approach in the domestic context. |
Used as supporting precedent for applying the necessity test in Irish jurisprudence. |
| Taylor v Anderton [1995] 1 WLR 447; Dolling-Baker v Merrett [1990] 1 WLR 1205; Science Research Council v Nassé [1980] AC 1028 |
Examples and authorities referenced within the Wallace Smith discussion as sources for identifying when disclosure is necessary and how the court may mitigate confidentiality concerns. |
These authorities underpinned the Court's approach that inspection and mitigation (redaction, confidentiality ring, limiting disclosure to legal advisors) are appropriate safeguards when necessity is established. |
| CHC Ireland DAC v The Minister for Transport [2023] IECA 335 |
Principle that once relevance is established necessity is prima facie established, subject to countervailing factors (such as confidentiality) and that confidentiality will not automatically prevent disclosure where justice requires it. |
The Court applied CHC to hold that confidentiality is not an absolute bar to disclosure and to emphasise the need to balance confidentiality against the interests of justice. |
| Tobin v Minister for Defence [2019] IESC 57 |
Discussion of proportionality: confidentiality does not justify refusal to disclose documents necessary for proper administration of justice; measures (recording and preserving documents, production at trial if necessary) can preserve confidentiality. |
The Court relied on Tobin to frame the proportionality assessment and to justify protective measures (e.g., preservation, redaction, restricted circulation) when allowing disclosure. |
| Independent Newspapers (Ireland) Ltd v Murphy [2006] IEHC 276 and related authorities (Yap v Children's University Hospital (unreported), Hartside Ltd v Heineken Ireland Ltd [2010] IEHC 3, Flogas Ireland Ltd v Tru Gas Ltd [2012] IEHC 259) |
Authorities discussing measures to protect confidentiality in discovery and the preservation of confidential documents pending trial. |
The Court looked to these authorities for procedural mechanisms (record and preserve; allow production at trial if necessary) and for practical case-management options to protect confidentiality. |
| Bristol-Myers Squibb Holdings Ireland Company v Norton (Waterford) Ltd trading as TEVA [2024] IECA 143 |
Consideration of redaction of exhibits in a commercial context; relevant to anonymisation practices. |
The Court referred to this decision when assessing the adequacy of the proposed redactions/anonymisations and considered the Second Respondent's redaction proposals in light of that authority. |
| Word Perfect Translation Services Ltd v Minister for Public Expenditure and Reform [2020] IESC 56 |
Discussion of the "confidentiality ring" as a mechanism to permit limited disclosure of confidential materials (generally to legal advisers and, where appropriate, to experts). |
The Court referenced this authority as an example of additional comfort/measure which may be adopted to protect confidentiality when sensitive materials are disclosed for litigation purposes. |
Court's Reasoning and Analysis
The Court began by outlining the applicable statutory and directive framework: Recital 82 of Directive (EU) 2019/1937 and section 16 of the Protected Disclosures Act 2014 (as amended) impose a clear duty of confidentiality in relation to the identity of reporting persons, with specified exceptions in section 16(2).
The Court accepted the Second Respondent's characterisation of the factual matrix: eight reports from seven reporting persons received in January 2024, overlapping allegations and recurring/template language, and a contemporaneous analysis (the OPDC Table) prepared to identify potential recipients and to inform the Second Respondent's decision-making.
The Court applied the established two-stage assessment used in disclosure/confidentiality contexts: (i) necessity — whether the documents are necessary for the purposes of the proceedings (litigious advantage, not otherwise available, and not oppressive) and (ii) proportionality — a balancing of the necessity of disclosure against confidentiality interests and any countervailing factors.
In assessing necessity the Court relied upon authorities (Wallace Smith and subsequent Irish cases) and accepted the Second Respondent's submissions that the related reports were necessary to show the context and cumulative considerations which informed the decision to transmit the Applicant's report to particular recipients. The Court also accepted that the analysis of overlapping or template elements across the reports was relevant to the Second Respondent's reasoning.
On proportionality, the Court emphasised that confidentiality is not an absolute bar and must yield where disclosure is necessary for the proper administration of justice. The Court considered the redacted/anonymised copies provided by the Second Respondent and concluded that, subject to some minor additional alterations made by the Court, the proposed redactions/anonymisations were comprehensive and appropriate to preserve confidentiality while allowing the Court and parties to assess the Second Respondent's decision-making.
The Court also considered procedural safeguards used in analogous contexts: inspection by the Court, redaction, limiting disclosure to legal advisors, and confidentiality rings. It noted that the Applicant and First Respondent had limited opportunity to comment on the redactions and that the third-party reporting persons had not been heard; accordingly, the Court imposed a procedure under section 16(3) of the Act to inform affected reporting persons and to afford them a right to apply to the Court within specified time limits before the documents were exhibited or otherwise disclosed.
The Court therefore concluded that the statutory exceptions under section 16(2)(a) and section 16(2)(c) could be engaged in this context and that the specific use of redacted/anonymised documentation for the Second Respondent's defence was both necessary and proportionate, subject to safeguards and the right of affected reporting persons to apply to the Court.
Holding and Implications
Core Ruling: The Court directed that the Second Respondent may use redacted/anonymised versions of the related protected disclosure documents in the defence of the proceedings, pursuant to section 16(2)(a) and section 16(2)(c) of the Protected Disclosures Act 2014 (as amended), subject to the conditions specified by the Court.
Key consequences and conditions imposed by the Court:
- The redacted/anonymised documentation, as amended by the Court, may be exhibited in the Second Respondent's affidavit(s) filed in defence, on the basis that such use is necessary and proportionate.
- Before furnishing the redacted/anonymised documentation to the Applicant and the First Respondent (or otherwise exhibiting them), the Second Respondent must serve the redacted/anonymised documentation on the relevant reporting persons together with an explanatory letter setting out the reasons for such usage and a copy of the judgment within 14 days. Those reporting persons will have liberty to apply to the Court within 21 days of such service.
- If no such applications are made, the Applicant and the First Respondent shall file opposition papers within the timetable ordered by the Court (specified in the judgment as within 14 days of the expiry of the time for such applications, with consequent filing timelines indicated).
- If any reporting person makes an application, the redacted/anonymised documentation shall not be exhibited or otherwise disclosed until that application has been determined by the Court.
- The Court listed the matter for case management mention on 28 October 2025 and granted liberty to apply, reserving costs of the application for directions.
Implications for precedent and practice: The Court applied established tests of necessity and proportionality drawn from existing authority and confirmed that, in suitable circumstances and with protective measures (redaction, notification and rights to apply, and potential confidentiality ring measures), redacted/anonymised protected disclosure material may be used in litigation. The judgment did not purport to set a novel rule beyond applying the existing framework; its effect is to permit the specific use of the redacted/anonymised documents in this case subject to the procedures and safeguards ordered.
