Anonymised Summary of High Court Ex Tempore Judgment
Factual and Procedural Background
This is a medical negligence action brought by the Plaintiff (a minor, suing by her father and next friend) against the Defendant, who operated The Hospital at all material times. The Plaintiff alleges that delay in diagnosing intracranial pathology (hydrocephalus) in the early days of her life led to severe brain injury and life-long major impairments. The Plaintiff was born on 23 January 2020. A trial date had been fixed for 11 April 2025.
By notice of motion dated 3 July 2025 the Plaintiff sought an order for the adjudication of a preliminary question of law pursuant to Order 25, rule 1, Order 34, rule 2 of the Rules of the Superior Courts, or the inherent jurisdiction of the Court. The proposed preliminary issue asked whether, when determining the adjustment rate(s) (personal injury discount rates) used to capitalise future expense/loss streams, the factors to be accounted for should include taxes and duties payable on income earned from such damages or on the principal sum awarded.
Legal Issues Presented
-
Whether, for the purpose of calculating adjustment rate(s) (personal injury discount rate(s)) used to capitalise future expense/loss streams in a personal injuries action, the factors to be taken into account include taxes and duties payable on: (a) income earned on such damages (from investment, placement, or other use), and/or (b) the principal sum of such damages.
-
Whether the Court should exercise its discretion to determine that question as a preliminary issue pursuant to Order 25, Rule 1, Order 34, Rule 2 of the Rules of the Superior Courts, or the Court's inherent jurisdiction (i.e. whether the matter should be carved out for a preliminary hearing rather than being tried as part of a unitary trial).
Arguments of the Parties
Plaintiff's Arguments
- The written submissions emphasise constitutional rights and rights under the European Convention on Human Rights; these materials form a primary focus of the Plaintiff's case on the procedural application.
- The Plaintiff contends that no evidence is required to determine the preliminary legal question posed.
Defendant's Arguments
- The Defendant contends that factual and expert evidence will be required to resolve the question and that such evidence is not agreed between the parties.
- The Defendant points to witness listings in the Plaintiff's disclosure schedule, including unnamed witnesses from the Office of Wards of Court and from the Assisted Decision-Making (ADM) system, together with expert reports from an economist and an actuary which were outstanding.

Rule or Principle Cited For |
Application by the Court |
| Campion v. South Tipperary County Council [2015] 1 I.R. 716 |
Establishment of the "unitary trial" as the default position; principles governing when a preliminary question of law should be heard separately (convenience, saving of time and cost, existence of agreed facts, and impact on the remainder of the case). |
The Court treated Campion as the starting point and applied the criteria summarised by Judge McKechnie (agreement on facts, discreteness of legal question, demonstrable saving of time and cost, convenience and overall justice) in exercising its discretion and ultimately found the requirements for a preliminary hearing were not met. |
| Duffy v. News Group Newspapers Limited (No. 2) [1994] 3 I.R. 63 |
Authority referenced for the common purpose of Orders 25 and 34: saving time and cost by way of preliminary processes. |
Referenced to support the general proposition that preliminary determination of legal points can save time and costs; the Court nevertheless required the specific Campion criteria to be satisfied in the present case and found they were not. |
| Croke v. Waterford Crystal Limited (Unreported, High Court, Smyth J., 26 June 2003) |
Used as an example of cases where preliminary questions are used to save time and cost. |
Referred to as part of the background authorities illustrating the Court's approach to preliminary issues; did not dictate outcome in this case. |
| Tara Mines v. Minister for Industry and Commerce [1975] 1 I.R. 242 |
Statement by O'Higgins C.J. about convenience: the court should consider whether resolution of the question before trial will reduce other issues significantly and whether its resolution is fair, proper and just. |
Quoted to underline the importance of convenience and fairness when deciding whether to hear preliminary legal questions; the Court applied these considerations and concluded convenience did not favor a preliminary hearing. |
| Vico Properties Limited v. Bank of Scotland Plc [2025] IEHC 401 |
Example where a potentially classic preliminary issue (statute-bar) was not ordered to be tried preliminarily due to insufficient agreement on factual matrix and because the issue would not decisively deal with all issues. |
The Court relied on the reasoning in Vico (Judge Bolger) to underline caution where there is insufficient agreement about the factual matrix and where the preliminary issue would not resolve the case; that reasoning supported the decision to refuse the present application. |
Court's Reasoning and Analysis
The matter was considered and decided by Judge Gillane in an ex tempore judgment. The Court began by identifying the governing procedural provisions (Order 25 and Order 34 of the Rules of the Superior Courts) and the established authorities on when a preliminary legal issue should be adjudicated prior to trial. The Court treated the decision in Campion as the starting point, specifically the criteria distilled by Judge McKechnie: (i) the existence of an agreed or undisputed factual matrix; (ii) a discrete legal question can be distilled from the facts; (iii) the decision of the question will result in a saving of time and cost compared with a unitary trial; and (iv) the process must be convenient and consistent with fairness and overall justice.
Applying those criteria, the Court identified a number of material factual and procedural obstacles:
- There is an existing full defence on causation and liability, and limited factual admissions only. An outstanding motion regarding genetic testing remained to be resolved and was to be contested.
- The parties do not agree on the facts underpinning the legal question; indeed they disagree on whether any evidence is required at all. The Plaintiff asserted that no evidence is necessary to decide the legal question; the Defendant maintained that evidence is required and identified various witnesses and outstanding expert reports (including an economist and an actuary) listed in disclosure.
- Because there is no agreed factual matrix, the Court considered it impossible to resolve the legal question reliably on a preliminary basis. The Court stated that impressions or suppositions would not suffice; where facts are in dispute appropriate evidence is usually necessary.
- The Court found that a ruling on the adjustment rate question would not substantially dispose of the action. Many substantial issues (notably causation and liability) would remain irrespective of how the preliminary question was decided.
- No specific evidence was presented to quantify or identify the time and cost that would be saved by a preliminary hearing, and it was not shown what witnesses could be dispensed with or how much the trial would be shortened. The Court expressed a concern that separating this issue could lengthen rather than shorten the litigation.
- The question posed was damages-related and, in the Court's view, could not by itself bring the proceedings to an end. The Court also noted the question might never become relevant depending on the outcome of liability and causation issues.
- The formulation of the proposed question was unclear: it did not specify whether the Court was being asked only whether taxes and duties are factors to be considered, or whether an actual specific rate was to be determined for use in the case.
The Court also had regard to the decision in Vico Properties, where a preliminary issue was refused because there was insufficient agreement as to the factual matrix and because the issue would not deal with all issues in the case. That authority reinforced the Court's cautious approach.
In light of these factors — absence of an agreed factual matrix, disagreement about the need for evidence, the likely limited impact of the ruling on the balance of the case, absence of any demonstrated saving of time and cost, uncertainty as to the duration and scope of a preliminary hearing, and the possibility that the question may never arise — the Court concluded it should refuse the application for a preliminary adjudication of the posed question of law.
Holding and Implications
APPLICATION REFUSED
Holding: The Court refused the relief sought in the notice of motion — i.e., it declined to order that the posed question of law be tried as a preliminary issue.
Implications: The direct effect of the decision is that the requested preliminary determination will not be made; the question of whether taxes and duties should be considered in determining adjustment rates will not be heard as a standalone pre-trial issue on the basis of the present application. The Court emphasised that numerous substantial issues (in particular causation and liability) would remain for resolution in the action irrespective of any decision on the adjustment rate question. The judgment does not purport to establish a new legal principle on the substantive question posed; rather it is a procedural ruling declining to order a preliminary hearing for the reasons stated. No order was made to determine the substantive adjustment-rate issue at this stage.
