| O'Domhnaill v Merrick [1984] IR 151 |
Jurisdiction to dismiss proceedings in the interests of justice where lapse of time causes a real and serious risk of an unfair trial, irrespective of culpability. |
The Court considered whether delay had made a fair trial impossible; concluded the evidence did not establish impossibility of a fair trial under this strand (some disadvantages existed but did not meet the high threshold of impossibility or "beyond the reach of fair litigation"). |
| Primor plc v Stokes Kennedy Crowley [1996] 2 IR 459 |
Traditional test for dismissal for delay where inordinate and inexcusable delay by the plaintiff (culpable delay) justifies dismissal; lower degree of prejudice required because of culpability element. |
The Court applied Primor as transformed by the subsequent Supreme Court authority (see Kirwan) and treated Primor principles through the modified "Primor-Kirwan" lens rather than the older formulation. |
| Kirwan v Connors trading as MJ O'Connor Solicitors & Ors [2025] IESC 21 |
Majority reformulation (or substantial modification) of the Primor approach: passage of time given central importance; two-year inactivity as critical milestone; guidance on cumulative inactivity and thresholds (2, 4, 5 years) with varying presumptions and burdens. |
The Court applied the Primor-Kirwan framework. It found very long cumulative inactivity (a fifteen-year block plus other periods), treated two years of procedural inactivity as a critical inflection point (with some excusatory exceptions), and concluded that the delay was inordinate and inexcusable under that test, justifying dismissal. |
| IBRC v Fingleton [2024] IESC 59 |
Recent Supreme Court consideration of the lapse-of-time jurisdiction and factors to be distilled from the authorities (presumption in favour of trial; distinction between unfair trial and litigation disadvantage; considerations from Manning; role of trial judge). |
The Court invited and considered submissions in light of this judgment and used the distilled factors (presumption of trial, need for weighty countervailing factors, distinction between unfair and imperfect trials, Manning factors) in its assessment under the O'Domhnaill strand and as context for Primor-Kirwan analysis. |
| Comcast International Holdings Incorporated v Minister for Public Enterprise [2012] IESC 50 |
Considered relevance of defendant inactivity and other factors excusing delay; helped identify excusatory factors in particular factual contexts. |
The Court accepted that Comcast remains relevant to identifying excusatory factors but concluded the present factual matrix did not show comparable reliance on an external investigatory body that would excuse the delay to the same extent. |
| Nash v Director of Public Prosecutions [2015] IESC 32 |
Emphasises strong constitutional presumption in favour of trial on the merits and guidance on what constitutes an unfair trial versus mere imperfections. |
The Court applied the presumption in favour of trial and the Nash guidance when assessing whether delay produced unfairness sufficient to warrant dismissal under the O'Domhnaill strand. |
| Manning v Benson & Hedges Limited [2004] 3 IR 556 |
Set out factors (Finlay Geoghegan J) relevant to assessing delay prejudice (defendant contribution, nature of claims, nature and role of documents/witnesses, prejudice asserted and supported by evidence). |
The Court used Manning factors in assessing specific prejudice (availability of witnesses, documents, defendant conduct) and in weighing explanations for delay. |
| Murray J's reasoning as endorsed in Kirwan (paragraphs 53-54) |
Identifies practical thresholds and how prejudice requirement varies with periods of total unexplained delay (less than 2 years, 2 years, 4 years, 5 years cumulative inactivity). |
The Court applied Murray J's framework (as endorsed by the majority) to analyse cumulative inactivity and the consequences at 2, 4 and 5 year milestones; found the proceedings comfortably within the four- and five-year guidance. |
| Allen v Redland Tile Co (Northern Ireland) Ltd [1973] NI 75 |
Interpretation of "proceeding" for purposes of rules: a "proceeding" is an act of formal procedural significance (application to court or other formal step). |
The Court relied on this interpretation to treat "inactivity" as absence of formal procedural steps and to calculate periods of inactivity for the Primor-Kirwan analysis. |
| Gibbons v N6 (Construction) Limited [2022] IECA 112 |
Under Primor the defendant does not have to establish the same level of prejudice as under O'Domhnaill; distinctions between the two strands. |
The Court noted this principle when assessing the level of prejudice required under the Primor-Kirwan strand and when distinguishing it from O'Domhnaill jurisprudence. |
| Quinn v Faulkner t/a Faulkners' Garage & Anor [2011] IEHC 103 |
Example of a case where delay has been treated as significant and relevant to dismissal. |
The judgment referred to this authority as a precedent pointing to situations where delay justifies dismissal; it formed part of the contextual authorities supporting the Primor-Kirwan thresholds. |
| Guerin v Guerin [1992] 2 IR 287 |
Example of exceptional circumstances (educational/social/economic disadvantage) that might justify allowing stale claims to proceed. |
The Court referred to this as an example of the narrow class of exceptional cases that might justify continuing proceedings despite extensive delay; it found no comparable pressing exigency of justice in the present case. |
| McKenna v Farrell [2007] IEHC 343 |
Illustration of public interest factors that may weigh in favour of continuation in some public law contexts. |
Invoked as an instance where public interest might permit continuation; the Court considered whether the present case reached that level and concluded it did not. |
| Campbell v Geraghty [2022] IEHC 241 |
Discusses defendant's reasonable reaction to litigation delay and the limited duty to be proactive. |
The Court cited passages supportive of treating defendants' inactivity as less culpable unless it amounts to acquiescence or positive encouragement to delay. |
