Cross-Examination in Judicial Review Confined to Genuine Factual Conflicts or Credibility/Reliability Challenges (Not Interpretations or Inferences)

1) Introduction

Ethical Farming Ireland v Minister for Agriculture, Ireland and the Attorney General (with notice parties including the Irish Farmers’ Association trustee and individuals) concerns a judicial review challenge brought by Ethical Farming Ireland, an NGO, alleging that the Minister for Agriculture (as “competent authority”) is failing to comply with Council Regulation (EC) No 1/2005 on the protection of animals during transport, specifically regarding the live transport of unweaned calves from Ireland to other EU Member States.

The judgment ([2026] IEHC 42, Cahill J, 27 January 2026) does not decide the substantive welfare challenge. Instead, it decides an interlocutory motion under Order 40, Rule 1 of the Rules of the Superior Courts seeking leave to cross-examine two factual deponents for the Minister: Ms Lorna Meaney (senior Department official) and Mr Ricardo Gatica (veterinary inspector). The parties’ central dispute was whether cross-examination may be ordered merely because the applicant contests the respondent’s interpretation of facts and the conclusions/inferences drawn from them, or whether a genuine conflict of fact (or a substantiated credibility/reliability challenge) is required.

2) Summary of the Judgment

The High Court refused leave to cross-examine Ms Meaney and Mr Gatica. Cahill J held that:

• Cross-examination in judicial review is permissible where there is a genuine conflict of fact on affidavit, or a substantiated challenge to the credibility or reliability of factual averments (for example, through documentary contradictions or conflicting affidavit evidence), and that dispute must be necessary to resolve a material issue in the proceedings.
• Bare contradictions/denials, and disputes over interpretations of facts, inferences, opinions, or submissions in affidavits do not justify cross-examination.
• The applicant’s asserted “conflicts” largely concerned (i) legal interpretation of the Regulation/2013 Act and (ii) competing interpretations of objective material (e.g., journey logs), rather than material factual disputes requiring oral testing.
• The alleged issues (water provision, missing journey logs, cramped conditions, feeding practices, timings at port, etc.) either were not true conflicts with Ms Meaney’s evidence, were not material to issues requiring determination, or could not be advanced by cross-examining Ms Meaney (who often did not claim personal knowledge of the specific incidents relied upon).
• As to Mr Gatica, there was no evidential basis to contradict his sworn explanation that an “N” entry about the water system was a typographical error; no affidavit challenged his credibility or reliability on that point.

The Court provisionally indicated that costs should be reserved to the trial judge, inviting short written submissions on costs.

3) Analysis

3.1 Precedents Cited

RAS Medical Limited v. Royal College of Surgeons in Ireland [2019] 1 IR 63 ("RAS Medical")

Cahill J treated RAS Medical as the “necessary starting point” and emphasised its “far-reaching” nature (also noting the characterisation in Re Bayview Hotel (Waterville) Ltd [2022] IEHC 516). Although RAS Medical did not arise from an application to cross-examine, the Supreme Court’s discussion of procedural fairness where a court is invited to reject sworn evidence was central.

The judgment relied particularly on Clarke CJ’s propositions that:

• If a party contends that an opponent’s sworn evidence lacks credibility or reliability, it is generally incumbent to cross-examine and put the challenge to the witness (fair procedures).
• It is not permissible to ask a court to reject sworn testimony (because of conflicting testimony or documents) without giving the witness an opportunity to address the challenge.
• Affidavits should be confined to evidence of fact; argumentative interpretations belong in submissions. This mattered because the applicant sought to cross-examine on “interpretation/construction” rather than factual dispute.

Cahill J used RAS Medical to cabin cross-examination to evidence “properly so-called”, and to reject the notion that cross-examination should be deployed to contest affidavit-based argument or interpretative gloss.

Hegarty v. An Garda Commissioner [2021] IECA 328 ("Hegarty")

Hegarty supplied the controlling appellate statement on when cross-examination is justified in judicial review: it is “relatively rare”, appropriate only where there is a genuine dispute of fact whose resolution is essential to determine the legal issues. Noonan J’s warning that cross-examination cannot be used to elicit facts to build a judicial review case was adopted as directly applicable to the applicant’s approach.

Cahill J also relied on Hegarty’s endorsement of Delany & McGrath and its rejection of “mere denial or non-acceptance” as a basis for cross-examination—an issue that arose because the applicant argued that widespread contestation of Ms Meaney’s affidavit warranted oral testing.

Somague Engenharia SA & Wills Bros Ltd v. Transport Infrastructure Ltd [2015] IEHC 723 ("Somague")

The applicant’s primary authority was Somague, read as permitting cross-examination even without a true factual conflict, where the dispute concerns the “construction/interpretation” of notes and conclusions drawn. Cahill J declined to treat Somague as expanding modern law, for five main reasons:

1. Hierarchy and time: Somague pre-dated RAS Medical and Hegarty, which are binding and definitive on the relevant principles in judicial review.
2. Affidavit discipline: The applicant’s reading of Somague was inconsistent with RAS Medical’s insistence that affidavits are not vehicles for argument/interpretation (and thus not an apt target for cross-exam).
3. Internal inconsistency/clarity: Cahill J highlighted that Somague also contains statements endorsing the requirement of a material conflict of fact and necessity, creating “lack of clarity” in the breadth claimed for it.
4. Context-specific (EU procurement): Baker J’s reasoning relied on the “utmost transparency” demands in procurement, potentially justifying greater scrutiny; that context was not present here.
5. Later “orthodoxy”: Post-Somague decisions reiterated the orthodox requirement of a relevant conflict of fact necessary to resolve the application.

Director of Corporate Enforcement v Seymour [2006] IEHC 369 ("Seymour")

Seymour was discussed as part of the historical development of cross-examination principles. O’Donovan J’s statements (including about testing a challenger’s “mindset” when an opinion is challenged) featured in Somague and were opened here. However, Cahill J noted that the Supreme Court, on the substantive appeal in Seymour, expressed doubt about the propriety of revisiting the evidential terrain beyond the inspector’s report—underscoring caution in treating Seymour as a general licence to cross-examine absent material factual conflict.

Irish Bank Resolution Corporation Ltd. v. Quinn [2012] 4 IR 381 ("IBRC v. Quinn")

IBRC v. Quinn was cited for recognising the court’s discretion and addressing criticism that Seymour went beyond prior authority. Cahill J used it as part of the lineage but placed decisive weight on the later binding statements in RAS Medical and Hegarty.

Irish Bank Resolution Corporation Ltd (in special liquidation) v Moran [2013] IEHC 295 ("IBRC v. Moran")

IBRC v. Moran supplied a frequently adopted two-limb test (also approved in Hegarty): (1) probable presence of a conflict on affidavits relevant to the issue to be determined and (2) the issue cannot be justly decided without cross-examination. Cahill J used this as consistent with the “orthodoxy” and as a counterweight to the applicant’s broader reading of Somague.

Trafalgar Developments Limited v. Mazepin [2022] 1 IR 339 ("Trafalgar")

Trafalgar was relied upon to show that even where Seymour/Somague are cited, courts have reiterated the orthodox necessity of a relevant affidavit conflict. Barniville J’s endorsement of the Delany & McGrath “orthodoxy” supported Cahill J’s approach.

Salmon Watch Ireland CLG v Aquaculture Licences Appeals Board [2023] IEHC 129 ("Salmon Watch")

The applicant invoked Salmon Watch as an example where cross-examination was permitted. Cahill J treated it as consistent with the binding principles: cross-examination is needed where facts (or, for experts, opinions) are genuinely in dispute and material. It did not assist the applicant because, on Cahill J’s assessment, the present motion did not identify such disputes.

Murphy v. Revenue Commissioners [2022] IEHC 352 ("Murphy")

Murphy illustrated that even if a factual conflict exists, it must be relevant to the legal issues. Cahill J’s reasoning aligned with Murphy by repeatedly asking whether the alleged conflict was necessary to decide any pleaded issue.

Re Bayview Hotel (Waterville) Ltd [2022] IEHC 516

Used to underline the breadth and significance of RAS Medical as a modern statement shaping affidavit practice and procedural fairness where sworn evidence is challenged.

3.2 Legal Reasoning

The judgment proceeds in a structured sequence that is itself instructive for future motions:

1. Identify the governing principles from binding authority (RAS Medical, Hegarty), including the proper function of affidavits and the limited circumstances in which oral testing is justified in judicial review.
2. Identify what issues truly fall to be determined in the underlying judicial review. Cahill J examined each pleaded ground (record keeping; injury/undue suffering; feeding; watering; inspection) and concluded that the dispute was largely one of legal interpretation of Regulation 1/2005 and the applicability/scope of the Animal Welfare Act 2013, as well as objective materials like journey logs.
3. Test each proposed cross-examination topic against necessity and materiality. The Court rejected attempts to manufacture “conflict” by pointing to (i) isolated observations by the applicant’s witness, (ii) general departmental evidence about systems and compliance practices, and (iii) disagreements about what should be inferred.

Several aspects of the reasoning are especially important:

• Distinguishing “system evidence” from “incident evidence”: Ms Meaney’s affidavits largely described regulatory systems, checks, and standard practices. The applicant relied on Ms Rowley’s observations of particular dates and images. Cahill J found these did not necessarily collide: the existence of a system is not disproved by an asserted instance of failure, and (critically) cross-examining a system-level deponent does not resolve what happened on a day she did not witness.
• No cross-examination to test “basis” or “means of knowledge” in the abstract: The applicant argued it should test the basis for Ms Meaney’s “conclusions” and probe her means of knowledge. The Court treated that as falling short of the required showing: cross-examination is not an entitlement to explore foundations absent a material factual conflict or a substantiated credibility/reliability challenge.
• Affidavit content discipline: By invoking RAS Medical, Cahill J effectively polices the line between evidence and submissions: disagreements with interpretative statements in affidavits are to be addressed in argument, not by oral interrogation of factual deponents.
• Judicial review not to be converted into fact-finding discovery by oral means: The judgment echoes Hegarty in rejecting cross-examination as a “fishing expedition” mechanism.

3.3 Impact

Although interlocutory, the judgment clarifies and consolidates a practical rule-set for cross-examination motions in Irish judicial review:

• Reaffirmation of the “orthodoxy” post-RAS Medical/Hegarty: Applicants must show a genuine, material factual conflict or a properly grounded credibility/reliability challenge; interpretative disagreements will not suffice.
• Constraining reliance on Somague outside its procurement context: The judgment signals that Somague cannot be relied upon to expand cross-examination in judicial review beyond what RAS Medical and Hegarty permit. This matters to litigants who attempt to convert disputes about “what documents mean” into a cross-examination entitlement.
• Incentive to plead and evidence disputes precisely: General assertions that “most averments are contested” will not do. Parties must identify (a) the exact factual proposition, (b) the contradictory affidavit/document, and (c) why resolution is necessary to decide a pleaded legal issue.
• Affidavit drafting consequences for public bodies: By echoing RAS Medical, the judgment encourages deponents to confine themselves to facts and clearly state the limits of personal knowledge. That, in turn, may reduce the surface area for cross-examination attempts.
• Strategic effect in regulatory litigation: Where challenges are largely about statutory/EU interpretation and the legality of policies/practices, the pathway to cross-examination is narrowed; the battleground shifts to objective records, expert evidence (where permitted), and legal argument.

4) Complex Concepts Simplified

Order 40, Rule 1

A procedural rule allowing courts to receive evidence by affidavit on motions/applications, but permitting the court to require the affidavit-maker to attend for cross-examination. It is discretionary, not automatic.

Judicial review

A procedure to challenge the legality of a decision, policy, or exercise of public power—typically focused on lawfulness, not a full trial of facts.

Genuine conflict of fact

Competing, specific versions of what happened (e.g., “X occurred” versus “X did not occur”), supported by admissible affidavit evidence, not merely “I don’t accept that” or disagreement about what should be inferred.

Credibility vs reliability

Credibility concerns whether the witness is truthful; reliability concerns whether the account is dependable (e.g., contradicted by documents, mistaken recollection). RAS Medical treats both as triggers for cross-examination if the court is being asked to reject sworn evidence.

Material issue / necessary to determine

A factual dispute only justifies cross-examination if it matters to the outcome—i.e., the court must resolve it to decide a pleaded issue.

Interpretations/inferences/opinions in affidavits

The Supreme Court in RAS Medical stresses that affidavits should not contain argument. Disagreement with an affidavit’s interpretation is typically addressed in legal submissions, not by cross-examination.

Hearsay on affidavit

Statements like “I was told…” by unidentified persons are generally weak or inadmissible as proof of the truth of the content. The judgment treated such material as not providing a proper basis to generate a cross-examinable factual dispute.

5) Conclusion

Ethical Farming Ireland v Minister for Agriculture and Ors [2026] IEHC 42 consolidates a clear procedural message: in judicial review, cross-examination of factual deponents is exceptional and will be ordered only where a party identifies a genuine, material conflict of fact or a properly grounded credibility/reliability challenge that must be resolved to decide the case. Disputes over interpretation, inference, and affidavit-based argument do not meet that threshold.

The decision also limits the utility of Somague as a general cross-examination authority in non-procurement judicial review, aligning the High Court’s approach firmly with the binding guidance in RAS Medical and Hegarty.
