Cumulative Delay Can Justify Strike-Out Even Without Two Years’ Immediate Inactivity (Order 122, r. 11 RSC)

1. Introduction

This High Court judgment (O’Donnell J., 22 December 2025) concerns a defendant’s motion to dismiss proceedings for want of prosecution due to delay. The plaintiff, David McEvoy, a paramedic employed by Dublin City Council, claimed damages for personal injuries arising from an alleged workplace accident on 23 October 2008 (a fall from ambulance steps), pleaded as negligence, breach of duty, and breach of statutory duty.

Proceedings were commenced by Personal Injuries Summons on 10 January 2011. The defendant issued its strike-out motion on 12 July 2024. A central issue was how the court should approach delay following the Supreme Court’s restatement in Kirwan v Connors & Ors [2025] IESC 21, including: (i) what counts as a “proceeding” under Order 122, rule 11 of the Rules of the Superior Courts (RSC); (ii) whether a motion can succeed absent a full two years of immediate pre-motion inactivity; and (iii) what role, if any, prejudice and “acquiescence” now play.

2. Summary of the Judgment

The court struck out the plaintiff’s action for want of prosecution. Although the court held that certain steps taken by the plaintiff in February 2023—particularly service of updated particulars—constituted a “proceeding” such that there was not a full two-year period of immediate inactivity before the July 2024 motion, it nevertheless found this to be an exceptional case where the court’s inherent jurisdiction should be exercised due to extraordinary cumulative delay (assessed at approximately 11½ years of plaintiff-responsible inactivity).

Applying Kirwan, the court held that concrete proof of prejudice was no longer essential at this level of delay: extensive delay itself justified dismissal unless there was a pressing “exigency of justice” to allow the matter proceed. Explanations offered (uncertainty regarding injuries, Covid-19 speculation, and solicitor-client breakdown) were held inadequate. The defendant’s conduct in preparing for a February 2023 trial date was treated as a form of acquiescence, but not of a kind sufficient to bar relief, particularly because the plaintiff appears to have vacated the trial date and then took no meaningful steps to relist.

3. Analysis

3.1 Precedents Cited

3.1.1 Kirwan v Connors t/a MJ O'Connor Solicitors & Others [2025] IESC 21

Kirwan is the controlling authority. The High Court treated it as a “significant readjustment” from the older approach associated with Primor, shifting the primary focus to the passage of time as an independent justification for dismissal.

O’Donnell J. relied particularly on the Chief Justice’s summary (para. 26) describing staged consequences of inactivity:

  • Before two years’ inactivity: dismissal generally requires abuse of process or O Domhnaill v. Merrick-level prejudice.
  • After two years’ total inactivity: dismissal becomes available; if not dismissed, strict directions may follow.
  • After four years’ total inactivity in oral-evidence cases: dismissal should ordinarily follow unless compelling reasons exist.
  • After more than five years’ complete inactivity: the court should have a generous power to dismiss unless a pressing exigency of justice requires trial.

Critically, the High Court treated Kirwan as reducing the centrality of defendant-specific prejudice evidence in cases of very long delay, aligning with the Supreme Court’s endorsement of time-based thresholds.

3.1.2 Primor plc v. Stokes Kennedy Crowley [1996] 2 IR 459

The judgment positions Primor as the “previous understanding” framework that had informed how these applications were historically argued (including greater attention to inordinate/inexcusable delay and prejudice). However, the court emphasized that Kirwan has now reoriented the analysis: the effluxion of time itself may justify dismissal without proof of additional prejudice.

3.1.3 Doyle v Commissioner of An Garda Síochána & Others [2025] IEHC 591

O’Donnell J. used Doyle to address two key points:

  • The meaning of “proceeding” in Order 122, r. 11—long understood as requiring a formal procedural step, not informal correspondence or notices such as a Notice of Intention to Proceed or Notice of Change of Solicitor.
  • Whether the two-year “immediate inactivity” requirement is absolute—Doyle suggested a general rule requiring two years immediately prior to the motion, but not an absolute bar where exceptional circumstances and overall delay warrant the court’s intervention.

The High Court agreed with this reading, and adopted it to strike out despite finding a qualifying “proceeding” within two years.

3.1.4 Allen v Redland Tile Co (Northern Ireland) Ltd. [1973] NI 75

Allen (Gibson J.) was used to supply a functional description of “proceeding”: an act of “formality and significance” done “in furtherance of an action,” typically a formal step required by rules or an application to court. This informed the High Court’s conclusion that updated particulars—though not always strictly “required”—could be sufficiently formal and action-advancing to count.

3.1.5 Other cited High Court decisions

The parties referred to Nowak v Institute of Chartered Accountants in Ireland [2025] IEHC 408 and Barr J. in Dennis Guilfoyle Developments Ltd v. Wardrop [2025] IEHC 414 as post-Kirwan applications. While not determinative in the reasoning as delivered, their citation reflects that the High Court is developing a consistent, Kirwan-aligned practice.

3.1.6 O Domhnaill v. Merrick (jurisdiction)

Although not cited with a full citation in the text, the judgment treats the O Domhnaill line as the traditional “prejudice-based” jurisdiction: at earlier stages (before two years’ inactivity under Kirwan), dismissal should typically require prejudice of that kind (or abuse of process). The importance here is contrastive: in extreme delay, Kirwan reduces the need to prove such prejudice.

3.2 Legal Reasoning

(a) Centrality of Order 122, r. 11 RSC and the “inactivity” metric

The court treated Order 122, r. 11 as the “starting point” post-Kirwan: two years without a “proceeding” triggers the entitlement to bring a dismissal motion. The court also aligned with Doyle that “inactivity” generally means absence of formal procedural steps; activity outside formal steps may be relevant, but mainly to explain delay rather than to calculate it.

(b) What counted as a “proceeding” here

The key technical question was whether actions in February 2023 were “proceedings” so as to defeat the two-year trigger. The court held:

  • Informal correspondence seeking loss-of-earnings information was not a proceeding (insufficient formality).
  • Service of updated particulars of personal injuries and of breach of contract/negligence was a sufficiently formal step, binding the plaintiff’s case and refining the issues for trial, and therefore was a “proceeding.”

The court supported this by reference to the procedural function of particulars (and the proposition in Delaney and McGrath on Civil Procedure that supplemental particulars should be provided where new information could otherwise cause surprise), and by the context: the case had been set down for trial for 14 February 2023 and progressed through S.I. 391 exchanges.

(c) Despite a qualifying “proceeding,” the court dismissed for cumulative delay (exceptional use of inherent jurisdiction)

Having found that the Order 122, r. 11 “two-year immediate inactivity” was not strictly met, the court nevertheless accepted—following Doyle and the majority approach in Kirwan preserving inherent jurisdiction—that there can be exceptional cases where dismissal is justified by the overall conspectus of delay.

The court conducted a broad “chunks of inactivity” analysis (echoing Murray J.’s guidance against aggregating trivial periods), identifying multiple substantial periods where the plaintiff failed to move the case forward, concluding the plaintiff was responsible for roughly 11½ years cumulative delay. The case was described as a relatively straightforward personal injuries action, making the delay particularly unjustifiable.

(d) Explanations for delay were rejected

  • Medical uncertainty: The court held personal injuries litigation does not require waiting until prognosis is fully certain; courts routinely assess future loss on evidence. In any event, surgery occurred in 2020 and updated medical position was available in 2022.
  • Covid-19: The plaintiff’s solicitor’s suggestion was speculative; no evidence showed what steps were intended but prevented.
  • Solicitor-client breakdown / change of solicitor: While potentially explanatory for some delay, the court found no adequate explanation for a 16-month gap in securing new representation, especially given the February 2023 trial setting and the unexplained vacation of that date.

(e) Prejudice and the recalibrated post-Kirwan balance

The defendant’s evidence of prejudice was described as “sparse” and not establishing concrete prejudice (aside from general memory fade and an initial claim that a witness was uncontactable, later contested). Nonetheless, the court held that where cumulative delay is extreme, Kirwan does not require specific proof of prejudice: the delay itself can justify dismissal, absent a compelling “exigency of justice.”

(f) Acquiescence

The court applied Kirwan’s distinction:

  • Mere defendant inactivity does not bar a motion (parties are “not co-adventurers”).
  • Only conduct reaching true acquiescence/encouragement (lulling the plaintiff) could materially affect the outcome.

The defendant’s cooperation in preparing for the February 2023 hearing was treated as “a form of acquiescence,” but not enough to defeat relief because (i) the plaintiff appears to have initiated the vacation of the trial date, and (ii) thereafter the plaintiff did not act to relist for 16 months.

3.3 Impact

  • Clarification of “proceeding”: The judgment is a practical data point that service of updated particulars can qualify as a “proceeding” under Order 122, r. 11 where it has sufficient formality and advances the litigation—whereas informal correspondence will not.
  • Exceptional strike-out despite no immediate two-year gap: The court confirms that defendants may still succeed in an “exceptional” case on the basis of extraordinary cumulative delay, relying on inherent jurisdiction informed by Kirwan.
  • Reduced emphasis on proven prejudice in extreme delay: Litigants should expect that very lengthy inactivity may itself be determinative, particularly in oral-evidence cases, even where concrete prejudice is not well-evidenced.
  • Trial dates and “last-minute activity”: Setting down for trial and engaging in pre-trial exchanges will not necessarily “cure” historical inertia, especially if the plaintiff then vacates the date and fails to relist promptly.
  • Practice signal to practitioners: If medical evolution is genuinely the reason for delay, the judgment indicates the need for (i) evidence-backed explanation, and (ii) proactive communication with the defendant, rather than a silent “wait and see” approach.

4. Complex Concepts Simplified

  • “Dismissed/struck out for want of prosecution”: the case is ended because the plaintiff did not progress it with reasonable diligence, not because the court decided the merits.
  • Order 122, r. 11 RSC: a procedural rule allowing a defendant to seek dismissal if no “proceeding” has occurred for two years. A “proceeding” generally means a formal procedural step that advances the case.
  • Inherent jurisdiction: the court’s residual power to control its process (including striking out for delay), operating alongside and informed by the rules.
  • “Cumulative delay”: the overall periods of substantial inactivity across the life of the case, assessed in the round rather than by counting every small gap.
  • Prejudice: disadvantage to the defendant caused by delay (e.g., lost witnesses, fading memory). Post-Kirwan, the need to prove specific prejudice diminishes as delay becomes extreme.
  • Acquiescence: more than silence; it implies the defendant’s conduct actively encouraged or induced the plaintiff not to proceed.
  • S.I. 391/1998: a procedural regime requiring exchange of witness schedules in personal injuries litigation; compliance shows trial preparation, but does not necessarily excuse long historical delay.

5. Conclusion

The judgment operationalises the post-Kirwan landscape in three important ways: it treats updated particulars as capable of being a “proceeding” for Order 122, r. 11 purposes; it confirms that extraordinary cumulative inactivity may still justify dismissal even where a strict two-year immediate inactivity period is not present; and it underscores that, at extreme levels of delay, the court may dismiss without requiring strong, specific proof of prejudice, absent a pressing justice-based reason to allow the claim proceed. For litigants, the decision is a clear warning that intermittent procedural activity and late-stage trial preparation will not necessarily rescue a claim burdened by prolonged, unexplained inertia.
