Plenary Summons Permitted Where Damages Include Trespass to the Person, Despite PIAB Authorisation Requirement

Case: St. John Harrington v O'Connor (Approved)
Citation: [2026] IEHC 52
Court: High Court of Ireland
Judge: Mr Justice Mark Heslin
Date: 30 January 2026

1. Introduction

This decision concerns an interlocutory defence application to stay or strike out plenary proceedings arising from alleged events on 5 October 2017 at a book launch. The plaintiff, Jill St John Harrington, sues James O'Connor for damages for assault, sexual assault, trespass to the person, and personal injury (with the pleaded injury being psychiatric harm including PTSD).

The central issues were procedural and jurisdictional: whether the High Court lacked jurisdiction because (i) the plaintiff allegedly failed to comply with the Personal Injuries Assessment Board Act 2003 (as amended) (“the 2003 Act”) and/or (ii) the plaintiff should have commenced the claim by “personal injuries summons” under the Civil Liability and Courts Act, 2004 (“the 2004 Act”), rather than by plenary summons. A further strand concerned service/notice difficulties arising from an incorrect address used in the PIAB process.

The Court repeatedly emphasised it was not engaging with the merits of the allegations, which were vigorously denied.

2. Summary of the Judgment

  • The defendant’s application to stay/strike out/dismiss failed on all grounds.
  • The PIAB Authorisation issued under s.17 of the 2003 Act was prima facie valid; the defendant did not judicially review it and could not simply ignore it in the plenary proceedings.
  • The incorrect address used in the PIAB application and correspondence did not justify dismissal: the defendant showed no real prejudice, particularly because PIAB had exercised its discretion not to assess the claim, and because PIAB resolution requires mutual consent.
  • The plaintiff was not required to commence by personal injuries summons under s.10 of the 2004 Act because the claim included “damages for trespass to the person”, which is expressly excluded from the definition of a “personal injuries action” in s.2 of the 2004 Act.
  • Service-based complaints were “misconceived” given the defendant’s receipt of the proceedings, entry of appearance, and failure to use the RSC mechanism to contest service.
  • Delay-based relief was rejected, including by reference to Kirwan v. Connors & Ors [2025] IESC 21.
  • The claim was not frivolous/vexatious: psychiatric injury was clearly pleaded and supported by intended medical evidence.
  • Costs: the Court indicated the plaintiff, being entirely successful on the motion, had a presumptive entitlement to costs under s.169 of the Legal Services Regulation Act, 2015.

3. Analysis

3.1 Precedents Cited

(a) Lawless v. Beacon Hospital & Ors [2019] IECA 256

The Court relied on the settled principle (noted at para. 29 of the judgment) that entry of an appearance can “cure” prior defects in service. This authority underpinned the Court’s dismissal of the defendant’s service complaints: the defendant did not pursue the procedural route to contest service (RSC Order 12, rule 26), and the conditional appearance (purportedly under Article 24 of Council Regulation (EC) 44/2001) was effectively abandoned, leaving an unconditional appearance.

(b) Kirwan v. Connors & Ors [2025] IESC 21

The Court treated Kirwan as governing the just disposal of delay-based applications. Given there was no two-year procedural inactivity (RSC Order 122) and the defendant’s motion itself effectively halted progress, the Court held it would be contrary to the interests of justice, and a “flagrant breach” of Kirwan principles, to dismiss for delay.

(c) Clarke v. O'Gorman [2014] 3 IR 340

This was the key authority for both sides. The Court extracted and applied several propositions from Clarke:

  • PIAB (2003 Act) scope: claims for assault/trespass typically remain “civil actions” for personal injuries under the 2003 Act. The High Court accepted that, viewed through the “lens” of the 2003 Act, the present claim was indeed a personal injuries civil action (psychiatric injury falling within “impairment of a person's physical or mental condition” by reference to the Civil Liability Act, 1961).
  • 2003 Act vs 2004 Act mismatch: the Court drew heavily from para. 35 of Clarke, emphasising that the 2004 Act is not expressed to be in pari materia with the 2003 Act and there is no obligation to read them together. Therefore, it is possible (even if “untidy”) for a claim to require PIAB authorisation under the 2003 Act but not be required to use the 2004 Act procedural form.
  • Meaning of the 2004 Act exclusion: the express exclusion in s.2 of the 2004 Act for actions where damages include “false imprisonment or trespass to the person” was treated as decisive on the form-of-commencement issue: where such damages are claimed, the action falls outside the statutory definition of “personal injuries action”, and s.10’s “personal injuries summons” requirement does not apply.
  • s.12 of the 2003 Act as procedural (in Clarke): the judgment also noted Clarke’s holding that s.12 does not operate as a jurisdictional bar in the strict sense (it bars a remedy if properly raised/pleaded rather than extinguishing the right). While the present case differed factually (authorisation had in fact issued), this reinforced the Court’s reluctance to treat alleged PIAB defects as automatically depriving the High Court of jurisdiction.

Importantly, the Court distinguished Clarke on its facts: in Clarke the plaintiff had not applied to PIAB at all and the strike-out was sought at trial. Here, the plaintiff had a s.17 authorisation before issuing proceedings, and the defendant had not challenged the Board’s decision.

(d) Murray v. Budds [2017] 2 IR 178

The Court accepted the proposition that “worry and stress”, short of a recognised psychiatric injury, is not compensable. However, it held this did not assist the defendant because the plaintiff pleaded “psychiatric injury” and PTSD, and indicated that further specialist evidence would follow.

(e) Wilkinson v. Ardbrook Homes Ltd [2016] IEHC 434

The Court applied the strike-out test described by Baker J: whether the plaintiff could “possibly succeed” on the pleadings and asserted facts. On that standard, the claim could not be characterised as frivolous or vexatious under Order 19, rule 28.

3.2 Legal Reasoning

(i) The “two-statute” structure: 2003 Act authorisation vs 2004 Act commencement form

The judgment’s most significant doctrinal contribution is its clear separation of:

  • Gatekeeping under the 2003 Act: whether the claim is a “civil action” for personal injuries requiring PIAB engagement and authorisation; and
  • Commencement form under the 2004 Act: whether the claim is a “personal injuries action” that must be commenced by “personal injuries summons”.

The Court held the present claim comfortably engaged the 2003 Act (psychiatric injury being “personal injury” for that Act’s purposes), and indeed the plaintiff sought and obtained s.17 authorisation. But the Court refused to “import” the 2003 Act’s broad capture into the 2004 Act’s narrower definition. Applying the plain words of s.2 of the 2004 Act, the inclusion of “damages for…trespass to the person” removed the case from the statutory category of “personal injuries action”, so s.10 did not oblige use of a personal injuries summons.

(ii) PIAB Authorisation validity and the wrong-address problem

The defendant’s complaint was that he had not received PIAB notice due to the plaintiff using an incorrect address (supplied via process-server enquiries). The Court accepted the address was wrong and that the PIAB letter was returned “unknown at this address”. However:

  • The authorisation correctly identified the plaintiff, the defendant by name, and the incident date; it explicitly authorised proceedings.
  • The authorisation was issued by PIAB (a non-party) and was not challenged by judicial review.
  • The defendant demonstrated no practical prejudice: PIAB had already decided not to assess (s.17 complexity), and PIAB can only resolve a claim if both parties consent (citing Clarke v. O'Gorman [2014] 3 IR 340 at para. 41 as referenced in this judgment).

On this analysis, the wrong address was a procedural mishap without demonstrated injustice sufficient to justify the drastic remedy of strike-out/stay.

(iii) Service, appearance, and abandonment of the Article 24 point

The Court treated service arguments as overtaken by events:

  • The defendant received the proceedings (ultimately via delivery to his son).
  • He entered an appearance and did not apply under Order 12, rule 26 to set aside service.
  • The conditional ground cited (Article 24 of Council Regulation (EC) 44/2001) was not pursued and was unsupported by evidence (no EU forum issue arose).

Drawing on Lawless v. Beacon Hospital & Ors [2019] IECA 256, the Court treated the appearance as curing service defects and rejected any suggestion that the defendant had not been served “in reality”.

(iv) Delay and abuse of process

The defendant’s wide-ranging allegations (including want of prosecution, unfairness, abuse of process, and lack of bona fides) were rejected. The Court pointed out the absence of Order 122 inactivity, and that progression was constrained by the defendant’s own motion. Kirwan v. Connors & Ors [2025] IESC 21 anchored the Court’s refusal to deploy dismissal as a disproportionate response.

3.3 Impact

(a) Practical rule on commencement form in intentional tort + injury cases

The judgment reinforces a practical procedural pathway for Irish litigants: where pleadings include “damages for trespass to the person” (including assault/sexual assault as pleaded intentional torts), the claim may fall outside the 2004 Act’s “personal injuries action” definition, meaning a plaintiff may procedurally proceed by plenary summons, even though PIAB authorisation may still be required under the 2003 Act.

(b) Clear endorsement of Clarke’s “mismatch” thesis

By explicitly adopting the proposition that a claim can fall under the 2003 Act but not the 2004 Act, the High Court strengthens the doctrinal separation between PIAB gatekeeping and the 2004 Act’s procedural reforms. Future jurisdictional challenges premised on “you needed a personal injuries summons” will likely turn on the pleaded inclusion (or not) of “trespass to the person” damages.

(c) Wrong-address PIAB issues: prejudice matters

The decision signals that defects in PIAB notice/service caused by address mistakes will not automatically invalidate proceedings; the defendant will need to demonstrate concrete prejudice, particularly where the Board has not assessed and where consent would in any event be required for resolution.

(d) Litigation conduct: service challenges must be taken properly

The judgment is also a warning that service complaints should be made promptly via the RSC mechanisms; entering an appearance and then seeking dismissal on service grounds is unlikely to succeed.

4. Complex Concepts Simplified

  • PIAB/Authorisation (2003 Act): for many personal injury claims, you must first apply to PIAB. If PIAB assesses, parties may accept/reject. If PIAB declines to assess (e.g. complexity) it issues an authorisation permitting court proceedings.
  • “Personal injury” includes psychiatric harm: by statutory definition, mental impairment/disease can be “personal injury”, so PTSD-type claims fall within personal injury concepts.
  • “Personal injuries action” (2004 Act) is narrower than “civil action” (2003 Act): even if your case is a personal injury claim requiring PIAB, it may still be excluded from the 2004 Act’s definition (notably where damages include “trespass to the person”).
  • “Trespass to the person”: an intentional tort category including assault/battery; it is generally “actionable per se” (you can sue without proving special damage), though personal injury damages may still be claimed.
  • In pari materia: a principle where related statutes are read together. Clarke (and this case) stress the 2003 and 2004 Acts are not required to be read together to align their scope.
  • Appearance and service: if a defendant enters an appearance and does not take the prescribed steps to challenge service, defects in service are often treated as cured.

5. Conclusion

The High Court refused to stay or strike out serious intentional-tort proceedings where the plaintiff had obtained a PIAB s.17 authorisation and where the defendant could not show prejudice from an address error in the PIAB process. The Court’s key legal clarification is that a claim may be captured by the PIAB regime under the 2003 Act yet fall outside the 2004 Act’s “personal injuries action” definition where damages include “trespass to the person”; accordingly, commencement by plenary summons is procedurally permissible and s.10 of the 2004 Act does not compel a personal injuries summons in such circumstances.
