Anonymised Summary of High Court Opinion (Case Stated) — [2025] IEHC 627

Factual and Procedural Background

This is an appeal by way of a Case Stated under section 949AQ of the Taxes Consolidation Act 1997 against a Determination of the Tax Appeals Commissioner ("TAC") dated 4 July 2024. The appeal was heard on 7 November 2025 by Judge Quinn. The Appellant is a retired farmer (referred to throughout as the "Appellant" or "Taxpayer"). The Respondent is the Revenue Commissioners (referred to throughout as the "Respondent").

Following an audit that extended over several years, during which the Respondent obtained documents from various third parties, the Respondent concluded that the Appellant had understated income for 2013–2015 and had not charged VAT on agricultural supplies sold in 2013 and 2015. The Respondent assessed income tax of €247,283.80 and VAT of €154,427.30; the figures were later reduced by the Respondent to €237,551.48 (income tax) and €126,963.97 (VAT) after correcting miscalculations. The Appellant appealed these assessments to the TAC; the appeals were consolidated and heard over three days in December 2023 and May 2024.

The Appellant provided three competing explanations for discrepancies between declared income and bank lodgements: (i) income came only from cattle sales and minor contract work; (ii) the Appellant allowed others to use his accounts; and (iii) he acted as a bulk purchaser and distributor of agricultural products. The TAC rejected all of these explanations and upheld the varied assessments. Those findings of fact were not challenged in the Case Stated.

At the TAC appeal hearing counsel for the Appellant argued that documents obtained by the Respondent from third parties had not been disclosed to the Appellant before the assessments and should have been excluded from the TAC hearing. The TAC rejected these process arguments in its Determination, concluding (inter alia) that (a) procedural complaints of that kind are generally a matter for judicial review, (b) there was no evidence the Respondent acted unfairly, (c) many of the relevant documents were the Appellant's own documents (for example, bank statements and receipts), and (d) the Respondent had obtained the documents because the Appellant had failed to cooperate with the investigation. The Appellant’s challenge was confined to these 'process' arguments in the Case Stated presented to the High Court.

Legal Issues Presented

1. Did the TAC fail to protect the Appellant's rights under Articles 41, 47 and 51 of the Charter of Fundamental Rights of the European Union and thus err in law?
2. Did the TAC err in law in permitting the admission of evidence procured by the Respondent from third parties?
3. Did the TAC fail to correctly apply the principles set out by the Court of Justice of the European Union (CJEU) in Glencore Agriculture Hungary Kft v Nemzeti Adó- és Vámhivatal (Case C-189/18) ("Glencore")?

Arguments of the Parties

Appellant's Arguments

• The Appellant (through Attorney Manley) conceded none of the TAC's findings of primary fact were challenged, and did not dispute the lawfulness of the Respondent's methods of obtaining the material. However, counsel contended that the Appellant had not been provided with materials obtained from third parties prior to the assessments and that this failure engaged rights under Articles 41, 47 and 51 of the Charter and the principles in Glencore and related CJEU authority. Counsel submitted that, as a consequence, the documents should have been excluded from the TAC appeal hearing and that the Appellant had been placed at an unfair "evidential deficit."
• The Appellant relied upon CJEU authority including WEBMINDLICENSES (Case C-419/14) for the proposition that the taxpayer must have the opportunity, within the administrative procedure, to access evidence and be heard about it.
• The Appellant referred to a prior TAC decision (Ref. 31TACD2023) said to have applied these procedural principles and argued similar treatment should occur here.

Respondent's Arguments

• The Respondent (through Attorney Bourke and Attorney Byrne) relied on the TAC's detailed findings of fact that were open on the evidence and unchallenged. Those findings included that the Appellant had been made aware that the Respondent had obtained cheques and other material from third parties, that the Appellant had been offered meetings (which he declined), and that the Respondent had engaged with the Appellant over a prolonged period.
• The Respondent submitted that the documents in issue were, in substance, the Appellant's own documents (bank statements, cheques, invoices/receipts) or documents to which the Appellant had access, which distinguishes this case from Glencore where different types of evidence and alleged fraud were involved.
• The Respondent submitted that the TAC's conclusion that the Appellant had not been treated unfairly was supported by the evidence, and that the procedural protections relied upon by the Appellant had been satisfied in practice (opportunity to access information and to be heard), citing WEBMINDLICENSES and the TAC’s factual findings.
• The Respondent also submitted that the TAC was entitled to consider the 'process' arguments and declined the invitation to exclude the evidence given the context and the Appellant’s non-cooperation.

Court's Reasoning and Analysis

The court's reasoning proceeds from the legal framework governing Case Stated appeals and the specific procedural context of taxation appeals:

1. Standard of review: The court recalled the principles from Mara v Hummingbird about the limited circumstances in which factual findings or inferences drawn by a commissioner may be set aside and emphasised that findings on primary facts supported by evidence should not be overturned.
2. Scope of TAC jurisdiction and ‘process’ complaints: The court acknowledged authorities (notably Lee and related cases) that ordinarily indicate procedural complaints about Revenue investigations should be pursued by judicial review. However, because the TAC had elected to address the process arguments substantively in its Determination, the High Court proceeded to review the TAC's reasoning and application of legal principles to the facts found by the TAC.
3. Contextual application of Glencore and EU procedural rights: The court emphasised that the rights of the defence and access to files are contextual and must be assessed with regard to the specific circumstances of each case (as stated in Glencore and explained in Quigley). The court noted that such rights are not unfettered and may be limited by legitimate public-interest considerations and proportionality.
4. Key factual distinctions: The court stressed the unchallenged TAC finding that the documents obtained from third parties were, for practical purposes, the Appellant's own documents (for example, bank statements, cheques, receipts/invoices). This factual finding distinguished the present case from Glencore, where material relied upon by authorities included third-party criminal investigation files not in the taxpayer's possession and where allegations of fraud featured prominently.
5. Opportunity to access and to be heard: The court examined the transcript extracts and other evidence relied on by the Respondent and the TAC's findings. The record showed the Appellant had been notified that the Respondent had obtained certain cheques and documents, had been offered meetings (which he did not accept), and the Respondent had engaged with the Appellant over an extended period. The TAC found (and the High Court accepted) that the Appellant had been given opportunities to access the information and to be heard, and that the Appellant had chosen not to cooperate with the Respondent's inquiries.
6. Ambush and timing of the complaint: The court noted the TAC's unchallenged finding that the procedural complaint was raised late — at the conclusion of the appeal hearing — which the TAC characterised as an "ambush." No adequate explanation was provided for the late invocation of Glencore-style arguments, and this timing weighed against the Appellant's contention of unfairness.
7. Conclusion of analysis: Given the factual matrix (documents were the Appellant's own or accessible to him, he had been informed and offered meetings, and he refused to cooperate), and given that the Appellant was not accused of fraud, the court concluded that the TAC correctly applied EU and domestic principles concerning fair procedures, access to evidence, and the right to defence. The admission of the documents at the TAC hearing was therefore not an error of law.

Holding and Implications

Holding (court's answers to the three questions raised):

• Answer to question (a): No. The TAC did not fail to protect the Appellant's rights under Articles 41, 47 and 51 of the Charter and did not err in law on that basis.
• Answer to question (b): No. The TAC did not err in law in permitting the admission of evidence procured by the Respondent from third parties.
• Answer to question (c): No. The TAC correctly applied the principles set out by the CJEU in Glencore in the context of the facts of this case.

Implications:

• Direct effect: The High Court upheld the TAC's Determination sustaining the varied tax and VAT assessments. The procedural challenge to the TAC's admission of third-party-obtained documents failed.
• Broader legal implications: The judgment applies existing authorities on the limits of the TAC's role, the contextual nature of the rights of defence/access to files under Glencore and related CJEU decisions, and reinforces that where documents are within a taxpayer's possession or access and where the taxpayer has refused to cooperate, the procedural protections do not necessarily require exclusion of such documents. The opinion does not purport to establish a novel precedent beyond applying these principles to the particular facts; no broader new legal rule was formulated by the court in this opinion.
