Summary of High Court Judgment

Factual and Procedural Background

The Plaintiff was the driver of a motor vehicle involved in a road traffic accident on 13 November 2017. The other driver (referred to in the record as the third-party driver) was insured by an insurer (referred to in the record as AXA Insurance DAC). Liability for the collision was conceded by the third-party driver's insurer and the Plaintiff's underlying personal injuries action has proceeded as an assessment-only claim.

The Plaintiff engaged four successive legal practices in respect of her underlying personal injuries matter: Company A (initial retainer from 14 November 2017 to 25 January 2018), then Company B (retainer commenced June 2018), then Company C (engaged April 2019), and ultimately Company D (following the dissolution of Company C). Company C was wound up in July 2020 and Company D later issued the personal injury summons in February 2021.

On 25 January 2024 the Plaintiff issued plenary proceedings alleging professional negligence against each of the four firms. The first three firms (Company A, Company B and Company C) each brought motions under Order 19, rule 28 of the Rules of the Superior Courts and/or the court's inherent jurisdiction to have the Plaintiff's claim dismissed on the grounds that (among alternatives) the claim discloses no reasonable cause of action, amounts to an abuse of process, is bound to fail, and has no reasonable chance of succeeding. No application to dismiss was made by Company D.

The hearing resulted in this approved judgment delivered by Judge O'Higgins on 31 July 2025 dealing with the three motions to dismiss made by the first three defendants.

Legal Issues Presented

1. Whether the Plaintiff's professional negligence claims against Company A, Company B and Company C disclose a reasonable cause of action for which relief should be granted.
2. Whether the Plaintiff's claims amount to an abuse of the process of the court.
3. Whether the Plaintiff's claims are bound to fail or have no reasonable chance of succeeding within the meaning of Order 19, rule 28 RSC.
4. Whether the Plaintiff's failure to obtain independent expert evidence (and to identify loss or prejudice causally linked to the alleged solicitor failings) is fatal to the pleaded professional negligence claims.
5. Whether the Plaintiff's case could be saved by amendment to the pleadings or by pre-trial procedures (i.e., whether dismissal should be resisted because an appropriate amendment would rescue the action).

Arguments of the Parties

Defendants' Arguments (Companies A, B and C)

• The motions sought dismissal under O.19 r.28 on the grounds that the Plaintiff's pleadings disclose no reasonable cause of action, amount to an abuse of process, are bound to fail and have no reasonable prospect of success.
• The defendants emphasised that the Plaintiff had not identified any actual loss or prejudice to her underlying personal injury claim arising from the alleged solicitor failings.
• The defendants submitted that the Plaintiff had failed to obtain independent expert evidence supporting a professional negligence claim and that launching such a claim without first ascertaining reasonable grounds was an abuse of process.
• They relied on the chronology and documentary evidence to show appropriate steps had been taken (e.g. issuing Section 8 letters where appropriate, commissioning medical reports, lodging PIAB documentation) and that the conduct complained of either did not occur or produced no adverse consequence.

Plaintiff's Arguments

• The Plaintiff contended in broad terms that the firms had committed various acts and omissions amounting to professional negligence, breach of fiduciary duty, and, in one instance pleaded, deceit. Particular complaints related to failure to obtain Garda reports, defective or incomplete letters of claim and PIAB Form A errors, failure to obtain independent technical or medical evidence, failures of communication and failures to advise about limitation or Section 8 requirements.
• The Plaintiff argued that dismissal should not be granted because of her constitutional right of access to the courts and contended that her pleadings could be amended (including proposed GDPR/data-protection related allegations) to save the case.
• The Plaintiff resisted the requirement to obtain an independent expert report and indicated she did not wish to commission such a report when afforded an opportunity by the court.

Court's Reasoning and Analysis

The court approached the applications under Order 19, rule 28 mindful that the power to strike out is to be exercised sparingly and subject to a high threshold because of the constitutional right of access to the courts. The court applied the governing principles (including that the Plaintiff's case is to be taken at its high-water mark and that the moving parties bear the onus of establishing that the pleadings disclose no reasonable cause of action or are otherwise an abuse or bound to fail).

The judge made a number of overarching factual and legal observations which informed the analysis:

• The underlying personal injuries proceedings are assessment-only and liability was conceded by the third-party insurer; the Plaintiff's route to compensation remains open.
• The Plaintiff had, at various times, withdrawn instructions, changed advisers and was disinclined to progress the underlying personal injuries hearing with expedition.
• A consistent theme was the Plaintiff's failure to identify any concrete loss, adverse consequence or prejudice to her underlying personal injuries claim that resulted from the alleged failings of Companies A–C. Establishing such causation / loss is a central element of a professional negligence claim.
• The Plaintiff had not obtained independent expert evidence to support a professional negligence claim (despite being given an opportunity by the court to do so). The court treated this omission as material: it reinforces that it would be an abuse of process to litigate serious allegations of professional negligence against legal practitioners without independent grounds.
• The Plaintiff repeatedly advanced complaints premised on misunderstandings of litigation practice or on clerical/formatting errors (for example omissions on a PIAB Form A, or blank boxes in pro forma documents). Many such matters were either remedied, insignificant, or, where imperfect, did not give rise to any demonstrated prejudice.
• Where the Plaintiff proposed amending her pleadings to add an entirely new class of claim (for example data-protection complaints under GDPR/Data Protection Act 2018), the court held that the amendment principle does not permit a plaintiff to introduce an entirely new case at the strike-out stage; the principle applies to rectifying deficient pleadings that mask an otherwise good cause of action, not to inventing a different claim.

In applying the law to the pleaded particulars against each of Company A, Company B and Company C, the court:

• Examined the chronology and documents and found, as regards Company A, that Section 8 initiating letters were sent promptly following the initial instruction, medical enquiries were made, and the Plaintiff herself paid the firm's fee and requested the file on withdrawal — facts inconsistent with the present negligence claim. No evidence of prejudice was established.
• Found that Company B's alleged clerical omission in an initial PIAB Form A (later corrected) did not mislead PIAB nor cause any identifiable loss, and that the PIAB decision to decline assessment was based on medical interaction issues, not the clerical omission. Allegations of deceit or deliberate concealment were unsupported.
• Concluded that Company C's activities (including that the firm was dissolved in July 2020 and file transfer arrangements) did not give rise to a storable cause of action because (among other reasons) the Plaintiff had not identified any adverse consequence to her claim arising from the conduct complained of and, in many respects, the alleged complaints related to events before or outside the firm's period of responsibility or were matters for the later firm.
• Repeatedly emphasised that absent evidence of causative loss (which the Plaintiff did not provide), negligent acts or omissions cannot found a professional negligence claim.
• Relied on the authority that launching professional negligence proceedings without first ascertaining reasonable grounds (normally by obtaining independent expert evidence) can amount to an abuse of process; in this case the Plaintiff had been afforded time to obtain such evidence but declined to do so.

The judge also took into account the Plaintiff's prior litigation (including unsuccessful judicial review proceedings and the appeal considered by the Court of Appeal) in which courts had previously rejected the Plaintiff's complaints about the propriety of counsel's and solicitors' conduct. Those prior rulings informed the assessment of the present pleadings and the Plaintiff's pattern of making serious allegations unsupported by evidence.

Holding and Implications

Holding: The court granted the applications of Company A, Company B and Company C and ordered that the Plaintiff's claims against each of those three defendants be STRUCK OUT on the alternative grounds that they:

• disclose no reasonable cause of action;
• amount to an abuse of the process of the court;
• are bound to fail; and/or
• have no reasonable chance of succeeding.

Implications:

• The immediate practical consequence is that the Plaintiff's professional negligence proceedings against the first three defendant firms are dismissed (struck out). The judge indicated that the parties will be heard on final orders and on costs, so detailed costs consequences were reserved for further hearing.
• The court found no basis to allow amendment that would rescue these claims; the Plaintiff's failure to obtain independent expert evidence and to identify causative loss was central to the dismissal.
• No new legal precedent was laid down beyond the court's application of established principles (including the sparing exercise of strike-out jurisdiction, the need to take the claim at its high-water mark, and the requirement that professional negligence claims be founded on reasonable grounds and, ordinarily, independent corroboration of causative loss). The decision applies those established principles to the facts of this case.

Additional Procedural Notes
