Summary of Ruling — Judicial Review (Record No. 2024/884 JR)

Factual and Procedural Background

The Plaintiffs comprised a minor child (who applied for a join-family visa in February 2023) and his mother who is resident and working in the State on a General Employment Permit. The minor's father also lives in the State. The mother's residence did not meet the one-year residency requirement to sponsor the minor's application, and the application was deferred. The join-family visa was refused in March 2024 and an appeal was lodged on 2 May 2024. Pre-action correspondence and requests to prioritise the appeal were exchanged with the Defendant, who initially declined prioritisation and referred to published processing times and a target of decisions within 12 months.

The Plaintiffs issued judicial review proceedings in July 2024 challenging alleged unreasonable delay and seeking mandamus in relation to prioritisation and/or the appeal. The Defendant issued an initial refusal to prioritise (11 July 2024) which was withdrawn and reissued (17 April 2025) and maintained. After authenticated documentation was furnished by the Plaintiffs, the Defendant indicated a likely decision date in mid-July 2025. The appeal decision issued on 14 July 2025, rendering the substantive proceedings moot. Costs up to 17 April 2025 were conceded by the Defendant; the parties disputed costs for the period from 17 April 2025 onward.

By Notice of Motion dated 4 February 2026 the Plaintiffs sought leave under Order 40 r.1 RSC to cross-examine the Defendant's deponent at a costs hearing, contending there were material factual disputes about website processing dates, retrospective updates, sequencing of appeals and staffing changes which made cross-examination necessary. The Defendant opposed the application and filed detailed affidavits (including exhibited redacted records of contemporaneous decisions) asserting the appeal was processed in chronological order and that improved processing times resulted from incremental staffing increases.

Legal Issues Presented

1. Whether leave should be granted to cross-examine the Defendant's deponent in otherwise moot judicial review proceedings for the sole purpose of determining a costs dispute.
2. Whether there exists a clear, genuine and material dispute of fact or credibility, central to the costs determination, which cannot fairly be resolved on affidavit and therefore necessitates oral testing under Order 40 r.1 RSC.

Arguments of the Parties

Plaintiff's Arguments

• There are material inconsistencies between the Defendant's affidavit evidence and contemporaneous information published on the Defendant's website about processing times, including retrospective updates to website data.
• The timing of the decision (issued the day before the listed hearing date) and related communications on the eve of call-over suggest the decision may have been expedited because of the proceedings, contrary to the Defendant's assertion that it issued in the ordinary chronological course.
• Oral testing of the Defendant's deponent is necessary to resolve credibility issues material to the costs adjudication.

Defendant's Arguments

• The decision issued in strict chronological order and was not prompted or expedited by the judicial review proceedings; any reduced processing time is explained by incremental recruitment and redeployment of staff.
• Discrepancies in published website processing dates are acknowledged and explained by documentary evidence and affidavit material demonstrating retrospective updates and occasional incorrect website updates; these matters do not require cross-examination.
• Exhibited anonymised and redacted records of contemporaneous decisions show other appeals lodged at the same time were processed at the same time without judicial review having been taken in those cases, supporting the ordinary-course explanation.
• Cross-examination is unnecessary where disputes can be resolved on affidavit and would cause disproportionate additional costs and use of court time for a costs-only issue.

Table of Precedents Cited

Precedent	Rule or Principle Cited For	Application by the Court
Ras Medical v. Royal College of Surgeons in Ireland [2019] 1 I.R. 63; [2019] IESC 4	Governing test for leave to cross-examine in judicial review: cross-examination only where clear, genuine and material dispute of fact/credibility central to outcome and not resolvable on affidavit.	The Court applied Ras Medical as the authoritative test and assessed whether the Plaintiffs had demonstrated a dispute of fact or credibility that could not fairly be resolved on affidavit.
M (A Minor) v. Minister for Foreign Affairs and Trade [2025] IEHC 581	Cross-examination may, in principle, be available in moot judicial review costs disputes where resolution of a credibility dispute warrants it; but cross-examination is exceptional and not lightly granted.	The Court relied on this authority as the most closely related precedent and concluded that while it establishes the principle that cross-examination can be available for costs issues, the facts here did not meet the threshold for leave.
In the Matter of Anvil Real Estate Limited [2025] IEHC 630	Example where leave to cross-examine was granted because of direct clashes between deponents and serious credibility issues affecting the outcome.	The Court used this decision to acknowledge circumstances in which cross-examination may be justified but distinguished that case from the present matter on the basis that detailed affidavits and documentary exhibits here addressed the credibility concerns.
CSNA Company Limited by Guarantee v. Minister for Health, Ireland and the Attorney General [2025] IEHC 594	Cross-examination refused where the issues were primarily legal rather than factual—judicial review focuses on law not fact.	The Court cited this case to reinforce the proposition that cross-examination is normally confined to disputes of fact material to legality and is inappropriate when issues are legal.
Hegarty v. Commissioner of An Garda Siochana [2021] IECA 328	Cross-examination in judicial review arises where legal determination depends on resolving factual disputes.	Invoked to support the principle that cross-examination is exceptional and tied to the necessity of resolving factual disputes for the legal determination.
Matta v. Minister for Justice [2016] IESC 45	Framework on costs in moot judicial review: whether proceedings procured the relief (or benefit) is central to costs assessment.	Used to frame the costs inquiry: if proceedings expedited a decision, the applicant may recover costs; if decision issued in ordinary course, no obvious basis for costs recovery.
Hughes v. Revenue Commissioners [2021] IECA 5; [2023] 3 IR 393	Further authority on costs in moot judicial review and determining costs on affidavits where a decision issues after proceedings are initiated.	Applied to support that costs in moot mandamus/delay cases are usually determined from affidavit materials and whether the proceedings led to a benefit.

Court's Reasoning and Analysis

Judge Phelan began from the well-established principle that cross-examination in judicial review is rare and should only be granted where a material dispute of fact or credibility is central to the outcome and cannot fairly be resolved on affidavit (Ras Medical). The Court identified the central factual dispute as whether the Defendant's decision was issued in the ordinary chronological course (unprompted) or expedited by the proceedings, which informs entitlement to costs.

The Plaintiffs relied on contemporaneous published processing times and the proximity of the decision to the hearing date to impugn the Defendant's account. The Defendant produced detailed affidavits (including a Department officer's affidavit about retrospective website updates and the Defendant's deponent's affidavit) and exhibited anonymised redacted records showing contemporaneous decisions processed in the ordinary course and evidence of incremental staffing increases improving processing times.

The Judge assessed whether the dispute was one that could not fairly be resolved on affidavit. Although some basis for questioning the Defendant's account existed (acknowledged website inaccuracies and coincidence in timing), the Court concluded that the Defendant's explanations were detailed, supported by documentary evidence and did not suffer the kind of deficiency seen in the lead authority relied upon by the Plaintiffs. The Court emphasised proportionality: permitting cross-examination for a costs-only issue would impose disproportionate additional expense and use of scarce court time.

The Court further observed that costs determinations in such moot delay cases are typically informed by affidavit evidence, chronology and documents rather than oral evidence, and that an award of costs does not engage the same constitutional stakes as substantive relief.

Holding and Implications

REFUSED — The application for leave to cross-examine the Defendant's deponent pursuant to Order 40 r.1 RSC was refused.

Implications:

• The costs dispute (particularly for the period from 17 April 2025 onward) will proceed without oral cross-examination of the Defendant's deponent and will be determined primarily on the affidavits, contemporaneous documents and chronology already before the Court.
• The Court noted concerns about proportionality and the exceptional nature of cross-examination in judicial review; no novel general rule was established and the decision was confined to the facts of this case.
• The Judge indicated that she will hear the parties on any consequential matters arising from this ruling.
