Hegarty v The Revenue Commissioners, Geary v The Revenue Commissioners, Ward v The Revenue Commissioners (Approved)

Factual and Procedural Background

This is an appeal by way of a Case Stated dated 12 June 2023 against a Determination of the Tax Appeals Commissioner ("TAC") dated 20 February 2023. The Case Stated, pursuant to s. 949AQ TCA 1997, sought the High Court's opinion on points of law arising from the TAC's Determination. The hearing in the High Court took place on 4–5 November 2025 and judgment was delivered by Judge Quinn on 5 February 2026.

The dispute concerned transactions entered into in 2007–2008 by the Appellants involving Gilt Forward Contracts ("GFCs") and Foreign Exchange Contracts for Difference ("FECDs") arranged by Company A. The central factual features found by the TAC (not disputed by the Appellants) included: acquisition and disposal dates, the same trade/expiry/settlement dates for paired GFC and FECD transactions, short life spans (4–8 weeks), an initial payment into solicitors' client account treated as margin, acquisition of government gilts by Company A acting as agent and corresponding FECD positions, and near-equal opposite monetary results (large exempt GFC gains and large FECD losses yielding a small net monetary loss). The Revenue (the Respondent) issued Notices of Opinion under s. 811 TCA 1997 (2012 and 2014) contending the arrangements were "tax avoidance transactions"; the Appellants appealed to the TAC (hearing Oct. 2022). The TAC determined for the Respondent that the transactions procured a tax advantage and misused s. 31 TCA 1997, disallowing the claimed capital losses save to the extent of the net monetary loss; the Appellants stated a Case Stated to the High Court.

Legal Issues Presented

1. Whether the TAC erred in law in its interpretation of the purpose of s. 31 TCA 1997 (including alleged failure to consider relevant authority).
2. Whether the TAC erred in law by failing to identify any purpose for s. 607 TCA 1997 before concluding misuse of s. 31.
3. Whether the TAC erred in law in holding that s. 31 had been misused, having regard to its purpose.
4. Whether the TAC erred in law by failing to recognise that, taken separately, the GFC and FECD had commercial purposes and taken together served as hedging/risk mitigation.
5. Whether the TAC erred in law by drawing conclusions as to probabilities of outcomes absent appropriate expert basis or by reasoning from actual outcomes a priori.
6. Whether the TAC erred in law in concluding the transactions were entered into primarily to give rise to a tax advantage.
7. Whether the TAC erred in law in holding the transactions were "tax avoidance transactions" as defined in s. 811 TCA 1997.
8. Whether the TAC improperly followed UK authorities rather than established Irish precedent.
9. Whether the TAC erred in law by restricting allowable CGT loss to the "actual financial loss".
10. Whether the TAC erred in law in excluding deduction of adviser fees when computing losses.

Arguments of the Parties

Appellants' Arguments

• The TAC misread or ignored concessions in the Revenue's expert evidence that the paired transactions could be regarded as hedges; each transaction had a commercial purpose.
• The TAC failed to give reasons for preferring the Revenue's expert over the Appellants' expert.
• The TAC incorrectly placed a burden on the Appellants to prove that claiming relief under s. 31/607 was not a misuse or abuse, contrary to the proper legal approach (relying on later authority).
• The TAC misinterpreted s. 31 and related provisions and substituted its subjective view of what the Oireachtas could have envisaged.
• The Appellants argued adviser fees were deductible under s. 552 as incidental costs directly referable to acquisition/disposal.

Respondent's Arguments

• The Court should "step into the shoes" of the TAC and assess whether the TAC's opinion under s. 811 was well held; s. 811(1)(b) permits that approach.
• The transactions were interdependent and, looked at holistically, had no commercial reality; they were designed to exploit s. 607 to generate tax-advantageous losses.
• The TAC permissibly preferred its expert's view; the FECDs and GFCs were effectively two sides of the same structure linked to the Euro Stoxx 50 index.
• The Court should not give weight to the subsequent statutory amendment (s. 546A, 2010) when interpreting the law as it stood at the relevant time.
• There was insufficient evidence to connect adviser fees to the transactions; TAC's exclusion of fees was open on the evidence.

Court's Reasoning and Analysis

The Court proceeded as follows:

• Role of Court: The Court declined the Respondent's invitation to "step into the shoes" of the TAC and form its own opinion under s. 811; the proper task on a Case Stated is to decide questions of law arising from the TAC's Determination rather than to replace the TAC's evaluative judgment.
• Expert evidence: The TAC's finding that the Respondent's expert "was unwilling" to accept that the transactions could be hedges was inconsistent with the expert's concessions in cross-examination (the expert accepted on multiple occasions that one transaction could be regarded as a hedge of the other). The Court held that the TAC's contrary finding was unsustainable and amounted to an error.
• Reasons for preferring evidence: Where a tribunal prefers one expert over another it must give adequate reasons. The TAC failed to engage with or explain rejection of the Appellants' expert evidence; that absence of reasoned analysis was an error of law per authorities cited.
• Materiality of errors: Those errors contaminated the TAC's central conclusions (paras. 116–117) that the transactions had no commercial purpose other than to generate a tax advantage, because the TAC's stated inability to identify any commercial motive relied on the misreading of expert evidence.
• Burden and s. 811(3)(a)(ii) (Relief Exclusion): The TAC treated it as a positive obligation on the Appellants to prove the relevant relief (s. 31/607) was not being misused or abused. The Court, relying on Hanrahan, held that the statutory task requires an objective assessment of the purpose of the relief provision and cannot be displaced by an evidential burden placed on the taxpayer in the way the TAC did; placing such a burden was an error of law.
• Interpretation of "misuse"/"abuse" and purpose of reliefs: The Court emphasised that s. 811(3)(a)(ii) mandates that a transaction arranged for obtaining a statutory relief is excluded from being a tax-avoidance transaction if it would not result directly or indirectly in misuse/abuse having regard to the relief's purpose. The Court found the TAC failed adequately to analyse the purposes of s. 31 and s. 607 in their statutory context (including the mirror relationship between allowable losses and chargeable gains under ss. 545–546) and therefore failed to apply correct statutory interpretation methodology (per Heather Hill/Bookfinders/O'Flynn/Hanrahan).
• Consequences for "actual loss" analysis: The TAC's conclusion that the FECD losses were not "actual monetary losses" was not sustainable on the material facts (which recorded real trades and settled cash losses). The question whether those losses amounted to misuse/abuse required proper purposive analysis of the relief provisions, which TAC did not undertake lawfully.
• Subsequent amendments: The Court declined to interpret the pre-2010 law by reference to the 2010 amendment (s. 546A) and followed established authority that subsequent amendments are not a reliable guide to the earlier statutory meaning; the Court therefore did not rely on the later amendment in its analysis.
• Fees: On the adviser-fees point the TAC's factual finding that there was no evidence connecting those fees to the transactions was open on the evidence; the Court did not disturb that finding.

Holding and Implications

HOLDING: The Court found multiple legal errors in the TAC's Determination that were material to its substantive conclusion that the Appellants engaged in "tax avoidance transactions" under s. 811 TCA 1997. For that reason the Determination cannot stand insofar as it concluded the transactions amounted to tax avoidance and misused s. 31/607. The TAC's finding on adviser fees was not disturbed.

Implications:

• The TAC's substantive Determination that the transactions were tax avoidance transactions and that the claimed capital losses were not allowable was legally unsustainable and must be set aside or re-opened for reconsideration consistent with the legal principles and analytic steps identified by the Court.
• The TAC's conclusion excluding adviser fees from allowable losses remains undisturbed on the evidence before the TAC.
• No new interpretative rule beyond application of established authorities was laid down; the decision directs that future re-assessment must (a) apply the statutory interpretative methodology set out in the authorities cited (including proper analysis of the purpose of relief provisions), (b) correct the identified errors concerning expert-evidence treatment and reasoning, and (c) avoid imposing an inappropriate burden on taxpayers under s. 811(3)(a)(ii).
