Mandatory “Proposed Duration” in Garda Suspension Notices and Continuity of the Commissioner’s Section 51 Process

Case: Hegarty v Commissioner Of An Garda Siochana (Approved) [2026] IEHC 332
Court: High Court of Ireland
Judge: Ms Justice Nessa Cahill
Date: 22 May 2026

1. Introduction

This judicial review concerns (i) a notice issued under section 51 of the Policing, Security and Community Safety Act 2024 indicating that the Garda Commissioner was considering dismissing a member on the basis that continued membership would undermine public confidence, and that dismissal was necessary to maintain that confidence, and (ii) a related suspension notice issued under section 50(3) and regulation 7 of the Policing, Security and Community Safety Act 2024 (Conduct) Regulations 2025.

The background was unusually protracted. The applicant (a Garda member) had admitted serious misconduct during earlier disciplinary proceedings under the Garda Síochána (Discipline) Regulations, 2007. After a prior cycle of section 14/section 51-type dismissal litigation (“Hegarty No. 1”), the Supreme Court ultimately rejected the “double jeopardy/constitutional justice” objection to invoking the Commissioner’s exceptional public-confidence dismissal power.

In 2025, after the Supreme Court decision, a fresh notice issued under section 51 (mirroring the earlier section 14 notice). The applicant challenged: (a) the lawfulness of initiating/continuing the section 51 process; (b) alleged failures of fair procedures (including refusal to provide “materials”); and (c) the lawfulness of the concurrent suspension.

2. Summary of the Judgment

  • Section 51 notice upheld: The Court refused to quash the section 51 notice and rejected the principal grounds advanced against the dismissal process (including challenges based on “materials”, “public confidence evidence”, and irrationality/ultra vires).
  • Successor Commissioner may continue the process: A change in office-holder did not invalidate the process; section 51 can be continued and concluded by a successor Commissioner.
  • Suspension notice quashed: The suspension notice was invalid because it failed to comply with the mandatory requirement in regulation 7(2)(c) to notify the member of the proposed duration of the suspension. A later corrective letter from the CSSO could not cure that defect.
  • Costs: The Court indicated a provisional view that the applicant should pay a proportion (but not all) of the Commissioner’s costs, inviting submissions.

3. Analysis

3.1 Precedents Cited and Their Influence

(a) The Supreme Court’s framing of the “exceptional” public-confidence dismissal power: Hegarty No. 1

The High Court treated Hegarty v Commissioner of An Garda Síochána [2025] IESC 36 as governing the interpretation of section 51 because section 51 substantially replicates section 14 of the repealed Garda Síochána Act 2005. The Supreme Court’s key influence was its insistence that the power:

  • is exceptional and available only in wholly exceptional cases;
  • must be exercised rationally, for its proper protective purpose (public confidence), not as a surrogate disciplinary sanction;
  • requires a high threshold: it is not enough that conduct is “wrongful” or “disgraceful”, nor that “some” public dissatisfaction exists.

The High Court applied that framework in rejecting (i) an argument that the applicant’s admitted conduct was intrinsically incapable of meeting section 51, and (ii) an argument that the Commissioner needed evidence of actual public outcry as a precondition to invoking section 51.

(b) Prematurity and the “irremediably wrong” threshold

The Court located the prematurity question within the standard judicial review approach in Rowland v. An Post [2017] 1 IR 355 (intervention is generally inappropriate unless a process has “gone irremediably wrong”). It then traced how that test has been applied in analogous Garda contexts:

  • Ivers v. Garda Commissioner [2021] IEHC 572, [2022] IECA 206: early-stage challenges may be premature where the process could correct itself; but section 14 could be ultra vires if facts are genuinely disputed and not established.
  • Murphy v Commissioner of An Garda Síochána [2023] IECA 92 and Habte v Minister for Justice [2021] 3 IR 627, [2020] IECA 22: courts should avoid assuming that decision-makers will not comply with fair procedures; proposals should usually be allowed to run their course.

Applying these authorities, Ms Justice Cahill held the proceedings were not globally premature because some complaints were “inherent” and not curable later (e.g., the “Commissioner ground”, the “irrationality/ultra vires” contention as framed, and the suspension challenge). However, granular challenges to the content of the notice (irrelevant considerations/omissions) and any early-stage “reasons” attack were treated as premature—appropriate for submissions under section 51(c) rather than immediate quashing.

(c) Finality and abuse of process: Henderson v. Henderson as refined in Munnelly

The Commissioner invoked the doctrine in Henderson v. Henderson (1843) 3 Hare 100, 67 E.R. 313, arguing that certain points could and should have been raised in the earlier litigation. The Court applied the structured approach in Munnelly v. Hassett [2023] IESC 29 (two-stage analysis: (1) could/should have been raised; (2) any special circumstances justifying re-litigation).

  • Irrelevant considerations/omissions: the Court found these were substantially available in 2020 given the near identity of the earlier notice, and no countervailing justification was identified. They were also premature in any event.
  • Irrationality threshold challenge: while the Court accepted the point could have been pleaded earlier, it held the Supreme Court’s later clarification of section 14/51’s “height of the bar” in [2025] IESC 36 provided a compelling reason not to bar the argument rigidly.

(d) Reasons timing in dismissal processes: McEnery

In rejecting any early-stage challenge to the sufficiency of reasons, the Court relied on McEnery v. Commissioner [2016] IESC 66: the constitutional obligation to give reasons crystallises when a final dismissal decision is made after submissions are considered, not at the initial proposal/notice stage.

(e) Evidence and affidavits by non-decision-makers: Keane

The Court addressed whether affidavit evidence from an internal affairs superintendent could establish the Commissioner’s opinions and reasons. Echoing Keane v. Commissioner [2021] IEHC 577, the Court attached no probative weight to assertions about what “the Commissioner” believed where the Commissioner did not swear evidence and the deponent did not explain a basis for knowledge of the Commissioner’s mind.

(f) Disclosure of underlying material in long suspensions: Baynham

The applicant relied on Baynham v. Commissioner of an Garda Síochána [2023] IEHC 735, [2025] IECA 194 to argue entitlement to all material “considered”. The Court distinguished Baynham as a case involving prolonged and repeatedly renewed suspensions, sparse notices, and an evidential vacuum, where fairness tipped toward providing “sufficient information” about factors weighed. Here, by contrast, the section 51 notice was detailed, the misconduct facts were admitted, and extensive documentation existed from earlier procedures and discovery.

(g) Statutory interpretation method and continuity of office

The Court referenced interpretative principle (including by allusion to) Heather Hill Management Company CLG v An Bord Pleanala [2024] 2 IR 222 for contextual statutory construction. It then relied centrally on section 22(2) of the Interpretation Act 2005 (powers conferred on an office-holder are exercisable by the holder for the time being), and on the internal architecture of the 2024 Act (notably continuity provisions in section 28) to reject the “same individual Commissioner must see it through” submission.

The Court also noted Lacramioara Amariei v. Chief Appeals Officer [2026] IESC 22 as a reminder against pre-emptive judicial review where statutory routes exist (though it did not treat Amariei as decisive on the facts).

3.2 Legal Reasoning

(a) Continuity of the Commissioner’s section 51 process despite change of office-holder

The applicant argued that because section 51 speaks of the Commissioner “remaining of his or her opinion”, only the same natural person could start and complete the process. The Court rejected that construction as inconsistent with:

  • section 28 of the 2024 Act (expressly providing for performance of the Commissioner’s functions during absence/incapacity/vacancy);
  • section 40 (the Commissioner may sue and be sued in the name of the office; contracts bind successors);
  • section 22(2) of the Interpretation Act 2005 (continuity of statutory powers as between successive office-holders).

The Court’s key conceptual move is to treat section 51 as a power of the office, requiring the incumbent to form the initiating opinion and the incumbent at decision time to decide whether, after submissions, the Commissioner “remains” of the opinion—without being bound by a predecessor’s view.

(b) Irrationality/ultra vires challenge rejected on admitted facts

Although the Supreme Court emphasised the “extreme” and “wholly exceptional” character of the power, the High Court declined to carve out categories of conduct as inherently incapable of meeting section 51. On orthodox judicial review principles (and expressly without “heightened deference”), the Court held it was not irrational for the Commissioner to consider section 51 on admitted misconduct involving sexual interaction with a witness in a Garda station during statement-taking.

(c) “Materials” disclosure: no general right to everything “considered”

The Court treated the request as neither a discovery application nor a free-standing entitlement to the entire internal decision file. Two factual anchors drove the rejection:

  • the misconduct facts were admitted and relatively clear; and
  • the applicant already possessed extensive documentation from the disciplinary process and from discovery in earlier litigation.

The Court also regarded the “considered vs relied upon/underpinning” distinction as unsupported by authority in this context. Baynham was distinguished as turning on prolonged suspensions, sparse reasoning, and the need for “sufficient information” about factors weighed—not a right to all documents considered.

(d) Public confidence: no requirement for evidence of public outcry

The applicant argued section 51 required evidence of “broad public disquiet” or a fact-finding inquiry into public confidence. The Court rejected this as inconsistent with:

  • the text of section 51 (an opinion “by reason of the member’s conduct”);
  • the protective function explained in [2025] IESC 36 (not reactive to temporary public anger); and
  • the impracticality and conceptual mismatch of requiring proof of actual unrest before a protective power can be deployed.

Importantly, the Court identified a drafting refinement in section 51 compared to former section 14: the phrase “by reason of the member’s conduct” now expressly qualifies both opinions in section 51(a)(i) and (ii). That textual structure further undermined the claim that a separate evidential showing of public reaction is a prerequisite.

(e) The decisive new point: suspension notice invalid for failure to state proposed duration

The Court’s central new operational rule arises from its strict approach to regulation 7(2). Under regulation 7(2)(c), the decision-maker shall notify the member of “the proposed duration of the suspension from duty”. The suspension notice stated the duration as “for the duration of the disciplinary proceedings” although no such proceedings were in being. A subsequent letter asserting this was a “typo” and should read “for the duration of the s. 51 proceedings” could not validate the initial statutory non-compliance.

The Court treated the requirement as mandatory, unqualified by “prejudice”, and held that neither contextual inference nor later correspondence satisfies the regulation.

This part of the judgment is particularly significant because it establishes that formal compliance with regulation 7(2)(c) is a condition of lawful suspension under section 50(3): a defective statement of duration is not a mere technicality.

3.3 Impact

(a) Immediate operational consequences for Garda suspensions

  • Mandatory content rule: Suspension notices must specify a proposed duration that is intelligible and accurate. A misconceived “duration” (e.g., referencing nonexistent proceedings) invalidates the suspension.
  • No cure by post-hoc clarification: Later solicitor/agency letters cannot retroactively repair non-compliance with regulation 7(2)(c). A compliant notice is required.
  • Reduced litigation risk by standardisation: The decision is likely to drive more careful templates and quality control for statutory notices, especially given the Court’s rejection of a “no prejudice” escape route.

(b) Section 51 continuity and administrative stability

  • Continuity across office-holder changes: The judgment confirms section 51 processes are not derailed by resignation/appointment of Commissioners.
  • But final decision must be the incumbent’s: While the process can continue, the incumbent must personally consider submissions and decide whether the Commissioner “remains” of the necessary opinion.

(c) Fair procedures: calibrated, context-dependent

  • Reasons timing: Any hard-edged “reasons” challenge generally crystallises at the final decision stage (per McEnery v. Commissioner [2016] IESC 66).
  • Disclosure: The case resists expanding Baynham into a general entitlement to all material “considered” at the proposal stage of section 51.

4. Complex Concepts Simplified

4.1 “Prematurity” in judicial review

Courts usually do not intervene in an ongoing statutory process unless it has already “gone irremediably wrong” (Rowland v. An Post [2017] 1 IR 355). This avoids courts deciding issues in an incomplete factual and procedural context. Here, some challenges were premature (content/omissions points), while others were not (inherent legal validity points and a facial statutory defect in the suspension notice).

4.2 The Henderson v. Henderson doctrine

It prevents parties from withholding arguments in one set of proceedings and raising them later, where they could and should have been raised earlier, subject to flexibility and special circumstances (Munnelly v. Hassett [2023] IESC 29). The Court used it to block re-litigation of notice-content points that could have been raised years earlier.

4.3 “Public confidence” as an “opinion” rather than a poll

Section 51 turns on the Commissioner’s opinion formed “by reason of the member’s conduct”. The Court held this does not require proof of public outcry or a formal inquiry into public sentiment. The opinion must be rational and grounded, but it is not conditioned on evidence that public anger has already manifested.

4.4 Office-holder continuity (Interpretation Act 2005, section 22(2))

When a statute gives a power to “the holder of an office”, section 22(2) ensures the power belongs to whoever holds that office at the relevant time. This prevents administrative paralysis when office-holders change.

5. Conclusion

[2026] IEHC 332 draws a sharp and practically important line between (i) challenges that properly await the end of a section 51 process and (ii) defects that invalidate a suspension immediately. The judgment’s most concrete new rule is that a Garda suspension notice under regulation 7 is unlawful if it fails to notify the member of the proposed duration of the suspension as required by regulation 7(2)(c), and that such a defect is not cured by later clarification.

At the same time, the Court strengthened administrative continuity by confirming that a successor Garda Commissioner may continue and conclude a section 51 process, and it resisted attempts to convert section 51 into a mechanism requiring proof of actual public outcry or broad disclosure of all documents “considered” at the notice stage.
