Pleading and Notice of Failure to Mitigate in Garda Compensation Claims under s.23 of the 2022 Act

1. Introduction

Gray v Commissioner Of An Garda Siochana (Approved) [2026] IEHC 557 is a High Court assessment of compensation under section 23 of the Garda Síochána (Compensation) Act, 2022 (as amended) following a conceded “malicious incident” in which a serving Garda was violently assaulted while on duty. Liability, the occurrence of a malicious incident, and causation of injury were not in dispute; the case turned on quantum (general damages and limited future specials).

The decision is particularly important for two reasons:

  • It clarifies that failure to mitigate cannot be sprung for the first time at trial by cross-examination where it was neither pleaded nor otherwise notified in advance.
  • It provides a careful template for applying the Personal Injury Guidelines in a Garda compensation claim where there are multiple significant injuries and no clear “dominant” injury.

2. Summary of the Judgment

Ms Justice Emily Farrell held:

  • The defendant was not entitled to raise failure to mitigate for the first time in cross-examination, having neither pleaded it nor given prior notice.
  • Even if mitigation had been properly in issue, it was not proved on the evidence; the burden lay on the defendant, and the plaintiff’s cessation of medication and limited counselling were not shown to be unreasonable.
  • Applying the Personal Injury Guidelines (as required by s.23), the Court valued the plaintiff’s principal injuries as:
    • PTSD: €45,000
    • Back injury with disc/nerve involvement: €40,000
    • Right shoulder injury: €16,000
    • Additional minor injuries (bites/scratches/bruising/knee trauma symptoms resolving): €5,000
  • Because of overlap and the single-incident recovery trajectory, the Court applied a global discount of €20,000, arriving at €86,000 general damages.
  • Special damages to date were agreed at €3,813, and the Court awarded €1,000 for future counselling, yielding total judgment of €90,813.

3. Analysis

3.1 Precedents Cited (and How They Shaped the Result)

A. Failure to mitigate: pleading, notice, and procedural fairness

  • Calix v. AG of Trinidad and Tobago [2013] 1 W.L.R. 3283 and Geest plc v. Lansiquot (St Lucia) [2002] 1 W.L.R. 3111: The Court adopted the Privy Council’s rule that where a defendant intends to contend that the plaintiff acted unreasonably in mitigation, clear notice must be given long enough before the hearing to allow the plaintiff to prepare, and where there are no pleadings, notice should be given by letter. This was central to the Court’s conclusion that the defendant could not raise mitigation “for the first time in cross-examination”.
  • Molloy v. Tipperary Glass Ltd [2022] IEHC 263: Simons J’s insistence that failure to mitigate should be expressly pleaded (or at least raised in correspondence pre-trial) was expressly approved and applied. Farrell J treated this as the governing Irish approach aligning with Geest/Calix.
  • Corless v. HSE [2023] IEHC 622: Farrell J noted a possible tension with the approach taken there, but characterised any inconsistency as obiter (i.e., not binding reasoning necessary for the decision). This is a significant handling of intra-court divergence: it signals a preference for the Molloy/Geest/Calix notice-based approach as the operative standard.
  • Buckley v. Linehan [2025] IEHC 101: Used as a contrasting example—there, mitigation arguments were discussed against a backdrop of evidence of refusing a treatment said to give dramatic benefit. Farrell J distinguished the present case: the plaintiff here did not refuse treatment, and financial constraints and medical context mattered.

B. Applying the Guidelines across multiple injuries: the “holistic” requirement

  • Zaganczyk v. John Pettit Wexford Unlimited Company and Another [2023] IECA 223: Cited for Noonan J’s emphasis that the award must fairly compensate for “all the suffering” endured.
  • Collins v. Parm and Others [2024] IECA 150 and Meehan v. Shawcove [2022] IECA 208: These anchored the Court’s approach to multiple injuries: the court must have regard to values for each injury (not only the most significant), must avoid overcompensation, and must place the claimant’s “constellation of injuries” proportionately within the overall scheme.
  • Lipinski (a Minor) v. Whelan [2022] IEHC 452, [2023] 3 I.R. 243: Referred to (via Zaganczyk) as an approved approach to the practical exercise of valuing multiple injuries and stepping back to ensure proportionality.
  • Delaney v. The Personal Injuries Board and Others [2024] IESC 10, [2024] 1 I.L.R.M. 149: Cited for the principle that if the Guidelines would produce an unjust award, the court may and must depart from them—supporting the Court’s emphasis that “have regard” does not mean mechanical application.
  • Somers v. Commissioner of An Garda Síochána [2025] IEHC 388: Used as a comparator for PTSD valuation in the Garda context; Farrell J treated it as useful but not determinative, distinguishing the greater severity/duration/impact of symptoms in the present case.

3.2 Legal Reasoning

A. Section 23 and the Personal Injury Guidelines: “have regard” plus proportionality

The Court held that s.23(1) requires the court to “have regard” to the Personal Injury Guidelines, and that s.23(4) mandates that approach in Garda compensation claims. Although s.23 (unlike s.22 of the Civil Liability and Courts Act 2004 as amended) does not require reasons for departure, the Court stated that the practical obligation to ensure proportionality and fairness remains—particularly the need to keep awards coherent with the Guidelines’ internal hierarchy (including the stated maximum for catastrophic injury).

B. Failure to mitigate: procedural gatekeeping and burden of proof

The reasoning has two layers:

  1. Procedural admissibility/entitlement: because mitigation was not pleaded and no notice given, raising it at trial was impermissible. The Court treated notice as essential to fairness: without it, a plaintiff may be deprived of the opportunity to marshal evidence (e.g. the details of the Employee Assistance Programme; precise finances; treating clinicians’ views).
  2. Substantive merits: even if it were in issue, the defendant failed to discharge the burden. The Court accepted unchallenged evidence about medication side effects, noted the absence of expert criticism of cessation, and accepted that financial constraints could rationally explain limited counselling beyond the employer-provided programme.

C. Valuation exercise: bracketing, then stepping back

The Court followed the Guidelines’ recommended methodology for multiple injuries:

  • Identify and value injuries by reference to the relevant brackets, then consider uplift/overlap rather than adding arithmetically.
  • Where no clear “dominant injury” exists, the overlap discount should be handled with care (the Court here found it was not possible to identify either PTSD or back injury as dominant).
  • A global “step back” ensured the final figure remained proportionate given the single traumatic event and linked psychological/physical recovery.

3.3 Impact

  • Mitigation defences in Garda compensation claims: the judgment strongly signals that defendants must plead mitigation expressly (or at minimum give clear advance notice). Trial-by-ambush on mitigation is unlikely to be tolerated, especially where the plaintiff could have gathered additional evidence if alerted.
  • Evidence expectations: the Court’s rejection of mitigation arguments was reinforced by the defendant’s failure to lead evidence. Future defendants who wish to run mitigation points (e.g., therapy uptake, medication adherence, rehabilitation choices) will likely need a properly pleaded case, timely notice, and evidential support (including clinical evidence, scheme terms, and financial analysis where affordability is invoked).
  • Guidelines application in multi-injury Garda cases: the approach provides a practical model for combining significant psychiatric injury with significant physical injury and avoiding both under- and over-compensation through an explicit overlap discount.
  • Comparator use: Somers is treated as informative but not a ceiling; Garda-context PTSD awards will remain fact-sensitive, especially as to duration, ongoing occupational impact, treatment intensity, and functional impairment.

4. Complex Concepts Simplified

“Failure to mitigate”
A defendant’s argument that the plaintiff unreasonably failed to take steps that would have reduced their loss (e.g. refusing reasonable treatment). It is not assumed; the defendant must plead it and prove it.
Pleading and notice
“Pleading” means setting out the defence in formal legal documents. “Notice” means warning the other side clearly in advance. The judgment emphasises that mitigation cannot be raised for the first time at trial without prior pleading/notice because it is unfair and deprives the plaintiff of an opportunity to prepare evidence.
Obiter
A judicial remark not necessary to decide the case. It can be persuasive but is not binding. Farrell J treated any apparent inconsistency in Corless as obiter.
“Have regard” to the Personal Injury Guidelines
The court must consider and use the Guidelines as a reference point, but is not required to apply them mechanically where that would be unjust. The court must still ensure the final award is fair and proportionate.
Dominant injury and overlap discount
In multiple-injury cases, courts often identify the most significant injury and then adjust for other injuries without double-counting overlapping effects (e.g. suffering, loss of amenity, work impact arising from the same recovery period). Where no dominant injury can be identified, the overlap analysis is more nuanced.

5. Conclusion

Gray v Commissioner Of An Garda Siochana (Approved) [2026] IEHC 557 consolidates a clear procedural and substantive message in Garda compensation litigation: a defendant who wishes to argue that a plaintiff failed to mitigate must plead it (or clearly notify it in advance), and must then prove it with evidence—particularly where the alleged mitigation concerns nuanced clinical decisions and affordability of therapy.

On quantum, the judgment is a worked example of applying the Personal Injury Guidelines to significant co-existing PTSD and back injury, valuing each injury, and then stepping back to impose an express overlap discount to reach a proportionate total. The result—€86,000 general damages plus special damages—illustrates a structured, comparator-aware, and Guidelines-anchored approach to Garda compensation awards.
