Taxpayers Beat Revenue on CGT Avoidance, Housing Guidelines Head to Europe, and Humphreys J. Delivers Five Rulings in a Single Day

The High Court delivered 0 judgments this week — and the stories behind them cut across tax law, housing policy, renewable energy, and tenancy rights. The headline: three taxpayers won a landmark capital gains tax case against the Revenue Commissioners, with Mr Justice Quinn finding multiple errors of law in the Tax Appeals Commissioner's determination. Meanwhile, Mr Justice Humphreys delivered five judgments on a single day — 10 February — including a referral to the Court of Justice of the EU that could reshape Ireland's apartment design standards and, with them, the economics of high-density housing.

  Business Post AI Pick: The Week's Lead Story
  The Revenue Commissioners lost on most grounds in [2026] IEHC 59 — a case involving Gilt Forward Contracts and Foreign Exchange Contracts for Difference used by taxpayers John Hegarty, David Geary, and Martin Ward to generate capital losses. Mr Justice Quinn found the Tax Appeals Commissioner made multiple errors of law in applying the anti-avoidance provision of section 811 of the Taxes Consolidation Act 1997. The practical implication: sophisticated CGT planning structures using gilts and FX instruments remain legally defensible — at least until Revenue appeals or the Oireachtas amends the legislation.

Pattern of the Week: The Planning Court's Busiest Day Five judgments from one judge on one day is unusual. Mr Justice Humphreys delivered rulings on a wind farm, a solar farm, apartment design guidelines, and two environmental information cases on 10 February alone. The pattern reflects the volume of planning and environmental litigation flowing through the High Court as Ireland's renewable energy buildout and housing crisis collide with legal challenge. Each of these cases has commercial consequences for developers, energy companies, and the State.

The Investigation: Five Cases, Five Sectors, One Busy Week

This week's judgments span tax avoidance, housing policy, renewable energy, environmental information, and tenancy law — a cross-section of the legal pressures on Irish business and the State. The most commercially significant: a CGT ruling that limits Revenue's anti-avoidance reach, and a CJEU referral that throws apartment design standards into European legal uncertainty. Below, the full case register for the period.

Case Register: 5–11 February 2026

Citation	Parties	Court	Judge	Type	Outcome
[2026] IEHC 59	Hegarty, Geary & Ward v Revenue Commissioners	High Court	Quinn J.	Tax/Revenue	Taxpayers win on most grounds; TAC errors of law found
[2026] IEHC 67	McDonald & Ors v Minister for Housing [No.3]	High Court	Humphreys J.	Constitutional/Admin	CJEU referral on apartment design SEA requirements
[2026] IEHC 65	Hoctor & Ors v An Coimisiún Pleanála (Carrig Renewable Energy)	High Court	Humphreys J.	Property/Planning	Wind farm planning upheld; most grounds dismissed
[2026] IEHC 62	Moss & Ors v An Coimisiún Pleanála (Lightsource solar, Kilkenny)	High Court	Humphreys J.	Property/Planning	103.64ha solar farm planning upheld; all grounds dismissed
[2026] IEHC 68	People Over Wind v Commissioner for Environmental Information [No.2]	High Court	Humphreys J.	Constitutional/Admin	CJEU referral; Coillte environmental information access
[2026] IEHC 71	Chimwala v Residential Tenancies Board	High Court	Cahill J.	Property/Planning	RTB upheld; missing signature on notice excused as a "slip"
[2026] IEHC 54	Student A v Trinity College Dublin	High Court	Simons J.	Constitutional/Admin	Anonymity refused; open justice principle upheld
[2026] IEHC 66	McDonald & Ors v Minister for Housing [No.2]	High Court	Humphreys J.	Constitutional/Admin	Companion to No.3; apartment guidelines challenge

Stress Signal: Revenue's Anti-Avoidance Defeat The Revenue Commissioners' loss in [2026] IEHC 59 is significant beyond the three named taxpayers. The case involved Gilt Forward Contracts and Foreign Exchange Contracts for Difference — instruments used to generate allowable capital losses. Mr Justice Quinn found the Tax Appeals Commissioner erred in law on multiple questions, including the application of the "Relief Exclusion" in section 811(3)(a)(ii) of the Taxes Consolidation Act 1997. Revenue's expert conceded key points under cross-examination at the TAC hearing. The so what: Revenue's ability to use section 811 to attack sophisticated CGT planning has been materially constrained. Watch for a Revenue appeal to the Court of Appeal.

Standout: Renewable Energy Wins Two Planning Battles Both the wind farm ([2026] IEHC 65) and the 103.64-hectare solar farm in Kilkenny ([2026] IEHC 62) had their planning permissions upheld this week. The solar farm — notice party Lightsource Renewable Energy Ireland Limited (CRO 570839, registered 2015, Ranelagh, Dublin) — is one of the largest solar PV developments in the country at over 100 hectares. Both cases were dismissed on all grounds, clearing the path for construction. For the renewable energy sector, this is a green light: the courts are not going to be a reliable blocking mechanism for objectors.

The Connections: What the Data Alone Cannot Tell You

This week's judgments are not isolated legal events — they are data points in larger structural stories about Ireland's housing crisis, its renewable energy transition, and the limits of Revenue's anti-avoidance powers. Cross-referencing the court record against CRO filings, property data, and Business Post coverage reveals connections that the case citations alone do not surface.

  Housing Policy in Legal Limbo: The CJEU Referral That Could Stall Apartment Supply
  Mr Justice Humphreys' referral in [2026] IEHC 67 asks the Court of Justice of the EU whether Ireland's apartment design standards — issued by the Minister for Housing without a Strategic Environmental Assessment — fall within the scope of EU Directive 2001/42. The Business Post reported on 7 February 2026 (Dublin Airport passenger cap to be permanently removed under new laws) that the government was simultaneously legislating to override planning constraints at Dublin Airport — a pattern of executive action on infrastructure that the courts are now scrutinising. If the CJEU rules that the apartment guidelines required SEA, every planning permission granted under those standards could face challenge. For developers, investors, and the 50,000+ homes-per-year target, this is the most commercially dangerous judgment of the week.

Solar Power Gets Its Day in Court — and Wins: Lightsource's Kilkenny Project Cleared The 103.64-hectare solar PV development in Kilkenny, with notice party Lightsource Renewable Energy Ireland Limited (CRO 570839), had all planning challenges dismissed in [2026] IEHC 62. CRO records show Lightsource Renewable Energy Ireland Limited was incorporated in October 2015 and is classified under NACE code "Production of electricity." The company's last filed accounts cover the period to 31 December 2022 — now over three years overdue — suggesting the Irish entity is primarily a project vehicle rather than an operating company with standalone revenues. The broader Lightsource group (now Lightsource bp, backed by BP) operates across multiple Irish SPVs, including Lightsource Ireland SPV 6 Limited (CRO 668339). The court's consistent upholding of renewable energy planning permissions this week signals that judicial review is not a viable long-term strategy for opponents of solar and wind development.

Revenue's Bad Week: CGT Anti-Avoidance Limits Exposed The Revenue Commissioners' defeat in [2026] IEHC 59 — involving Gilt Forward Contracts used by three taxpayers to generate capital losses — is a significant constraint on section 811 of the Taxes Consolidation Act 1997. The case was a Case Stated from the Tax Appeals Commissioner, meaning the High Court was reviewing questions of law, not re-hearing the facts. Mr Justice Quinn answered 10 questions, finding largely in favour of the taxpayers. The comparison to UK anti-avoidance cases (Ramsay, Schofield) was explicitly considered and distinguished. For tax advisors, this is a green light to revisit similar structures. For Revenue, the options are an appeal to the Court of Appeal or a legislative fix — neither is quick.

An Coimisiún Pleanála: At the Centre of Everything An Coimisiún Pleanála — Ireland's planning authority, formerly An Bord Pleanála, rebranded in 2023 — featured in four of this week's judgments: the wind farm case, the solar farm case, the apartment guidelines CJEU referral, and the Dublin Airport passenger cap legislation reported by the Business Post (Cabinet approves removal of Dublin Airport passenger cap). The planning body is simultaneously defending its decisions in court, being referred to the CJEU, and being legislated around by the government on Dublin Airport. This is an institution under extraordinary pressure from multiple directions at once.

Tenancy Law: The Signature That Wasn't Missing The RTB case [2026] IEHC 71 — Chimwala v Residential Tenancies Board — turned on whether a missing signature page on a termination notice invalidated the notice. Ms Justice Cahill upheld the RTB Tribunal's finding that the omission was a "slip" excusable under section 64A of the Residential Tenancies Act 2004. The practical implication for landlords: a procedural defect in a termination notice does not automatically invalidate it if the full signed notice was actually served. For tenants, the ruling narrows the grounds for challenging notices on technical grounds. The property at issue was Apartment 8, Mill House, 72/73 O'Connell Street, Waterford — a reminder that tenancy disputes are playing out in every county, not just Dublin.

The Radar: Three Signals Worth Watching

Renewable Energy Planning: The Courts Are Not a Veto Two renewable energy planning permissions upheld in a single week — Lightsource Renewable Energy Ireland Limited's 103ha Kilkenny solar farm ([2026] IEHC 62) and Carrig Renewable Energy's wind farm ([2026] IEHC 65) — signals a structural shift in how the courts are treating renewable energy challenges. Both cases saw all grounds dismissed. The pattern: objectors are losing consistently, and the legal costs of failed challenges are significant. Watch for a reduction in the volume of renewable energy judicial reviews as the cost-benefit calculation shifts against challengers.

CGT Anti-Avoidance: Section 811 Under Pressure The Revenue Commissioners' loss in [2026] IEHC 59 is the latest in a series of setbacks for Revenue's use of section 811 of the Taxes Consolidation Act 1997 against sophisticated CGT planning. The case involved Gilt Forward Contracts and FX instruments — structures that are not exotic but are technically complex. Watch for Revenue to seek a leapfrog appeal to the Supreme Court, or for the Department of Finance to include a legislative amendment in the next Finance Bill.

Apartment Design Standards: A CJEU Time Bomb The referral in [2026] IEHC 67 asks whether Ireland's apartment design guidelines required a Strategic Environmental Assessment under EU Directive 2001/42. If the CJEU rules yes, the guidelines — and every planning permission granted under them — could be vulnerable to challenge. The Irish government has requested priority treatment of the reference. Watch for the CJEU's initial response on priority status within the next 60 days, and for developers to begin stress-testing their planning permissions.

The Deep Dive: One Tax Case, One Planning Giant, and the People Behind Them

Two entities this week warrant deeper investigation: the Revenue Commissioners' defeat in the CGT avoidance case, which reveals the limits of Ireland's primary anti-avoidance provision; and Lightsource Renewable Energy Ireland Limited, the notice party in the Kilkenny solar farm case, whose CRO profile tells a story about how international renewable energy groups structure their Irish operations.

Hegarty, Geary & Ward v Revenue Commissioners — The CGT Case That Rewrote the Rules

[2026] IEHC 59, delivered by Mr Justice Quinn on 5 February 2026, is a Case Stated from the Tax Appeals Commissioner. The three taxpayers — John Hegarty, David Geary, and Martin Ward — used Gilt Forward Contracts (GFCs) and Foreign Exchange Contracts for Difference (FECDs) to generate allowable capital losses. Revenue argued these transactions were tax avoidance under section 811 of the Taxes Consolidation Act 1997. The TAC found in Revenue's favour. The High Court found the TAC erred in law on multiple questions.

Issue	TAC Finding	High Court Finding
Section 811 anti-avoidance applies	Yes — tax advantage obtained	Multiple errors of law found
Relief Exclusion (s.811(3)(a)(ii))	Not applicable	TAC erred in interpretation
Expert evidence assessment	Revenue expert preferred	Revenue expert conceded key points under cross-examination
Deductibility of advisor fees (CGT)	Not deductible	Answered in taxpayers' favour
UK anti-avoidance comparison (Ramsay)	Applied by analogy	Distinguished from Irish law
Overall outcome	Revenue wins	Taxpayers win on most of 10 questions

Reading Between the Lines: What This Means for Revenue's Toolkit Section 811 is Revenue's primary general anti-avoidance provision — the backstop when specific anti-avoidance rules don't apply. A High Court finding of multiple errors of law in its application is not a minor procedural setback; it is a substantive constraint. The case involved instruments — gilts and FX contracts — that are widely used in sophisticated tax planning. Mr Justice Quinn's analysis of the "Relief Exclusion" and his rejection of the UK Ramsay doctrine by analogy gives tax advisors a clear roadmap for structuring similar transactions. Revenue's options are limited: appeal (which takes years) or legislation (which takes a Finance Bill cycle). In the interim, the ruling stands.

The question for the next Finance Bill: Will the Department of Finance move to amend section 811 to close the gaps identified by Mr Justice Quinn, or will Revenue seek a leapfrog appeal to the Supreme Court on the grounds of general public importance?

Lightsource Renewable Energy Ireland Limited — The Solar Giant Behind the Kilkenny Case

Lightsource Renewable Energy Ireland Limited (CRO 570839) is the Irish operating entity of Lightsource bp, the global solar developer backed by BP. Incorporated in October 2015 and based at Trinity House, Charleston Road, Ranelagh, Dublin, the company holds the NACE classification "Production of electricity." It was the notice party in [2026] IEHC 62, which upheld planning permission for a 103.64-hectare solar PV development in Kilkenny — one of the largest solar projects in the country.

Why It Matters: The SPV Model Behind Ireland's Solar Buildout Lightsource Renewable Energy Ireland Limited's CRO profile is a textbook example of how international renewable energy groups structure Irish operations: a nominal share capital of €0.10, UK and Spanish directors, a company secretary (Millbank Trustees Limited) that serves multiple Lightsource entities, and accounts that are now over three years behind the current date. This is not a sign of financial distress — it is the standard SPV (Special Purpose Vehicle) model for project finance. The real financial activity sits in the project-level entities (like Lightsource Ireland SPV 6 Limited, CRO 668339) and in the UK parent. The Irish entity is a holding and development vehicle. The Kilkenny solar farm, once operational, will generate revenue through a Power Purchase Agreement or the RESS auction scheme — none of which will be visible in the Irish entity's accounts.

Watch for: Lightsource's annual return for the period to 30 September 2024 is now overdue. If the company fails to file within the statutory period, it faces a late filing penalty and potential strike-off proceedings. Given the scale of the Kilkenny project, a strike-off would be commercially disruptive — watch for a filing in the coming weeks.

What they do: Lightsource Renewable Energy Ireland Limited is the Irish development vehicle for Lightsource bp, one of the world's largest solar energy developers. The company holds and develops solar PV projects in Ireland, operating through a network of SPVs. The Kilkenny project — 103.64 hectares, 10-year planning permission — is among the largest solar developments in the country.

Why it matters: The company's CRO profile illustrates how international renewable energy capital flows into Ireland: through lightly capitalised Irish entities with overseas directors, using the SPV model to ring-fence project risk. The accounts are now over three years behind the current date, which is standard for project vehicles but creates opacity around the financial performance of individual projects. With the Kilkenny planning now cleared, the next step is grid connection and financing — neither of which will be visible in Irish public filings.

The number that matters: €0.10 — the issued share capital of a company developing one of Ireland's largest solar farms. This is not a sign of undercapitalisation; it is the SPV model in action. The real capital sits in the project finance structure, not the Irish holding entity.

The Broader Picture

The Companies Registration Office

The CRO registered 559 new companies in the week of 5–11 February 2026 — a normal week by recent standards. The new registrations include a mix of holding companies, professional services firms, and retail entities. Three external companies (registered in Ireland but incorporated abroad) were also registered in the period, including MAST 2026-1 Limited (CRO 910503, registered 10 February, Molesworth Street, Dublin) — a structured finance vehicle whose name suggests a 2026 securitisation programme. The CRO also shows 319 new business name registrations for the period.

Company	CRO No.	Type	Sector	Notable
MAST 2026-1 Limited	910503	External company	Finance/Securitisation	Registered 10 Feb; Molesworth St, Dublin
Iarlaith Keane Golf Limited	808345	LTD	Retail (golf)	Portmarnock, Dublin; €100k authorised capital

Gemford Capital Limited	808329	LTD	Holding companies	Malahide Marina, Dublin; €1m authorised capital
Aegis Core Limited	808335	LTD	Web portals	Blackrock, Dublin; €10k issued capital

Property Markets & Plans

The property market recorded 759 transactions in the week of 5–11 February 2026, with an average price of €389,503 and a median of €344,367. The highest transaction in the period reached €11.6 million — a significant commercial or high-end residential deal. In Kilkenny — the county at the centre of this week's solar farm planning judgment — 28 transactions were recorded, ranging from €20,000 to €500,000, with the top sale at Knockhouse, Kilmacow (€500,000). The property market context matters for the apartment design guidelines CJEU referral: if those guidelines are invalidated, the pipeline of apartment developments approved under them faces legal uncertainty at a time when the market is already supply-constrained.

Address	County	Amount	Date	Note
Knockhouse, Kilmacow	Kilkenny	€500,000	9 Feb 2026	Top Kilkenny sale; solar farm county
Bishopslough, Bennettsbridge	Kilkenny	€285,000	9 Feb 2026	Rural residential
72 Selskar, Larchfield Court	Kilkenny	€250,000	9 Feb 2026	City residential
127 McDonagh Junction	Kilkenny	€235,000	9 Feb 2026	City residential
3 Maryville, Castlecomer	Kilkenny	€100,000	11 Feb 2026	Rural; below county median

Property Watch: The Kilkenny Connection The county where Lightsource Renewable Energy Ireland Limited's 103-hectare solar farm received its planning clearance this week recorded 28 property transactions in the same period, with a median price well below the national average of €344,367. Rural Kilkenny — where the solar farm sits — is a county where agricultural land values and renewable energy development are increasingly in tension. The planning clearance for a 103-hectare solar PV site represents a significant land use change in a county where comparable residential properties sell for €100,000–€285,000.

The Week Ahead

This week's judgments set up three forward-looking stories that will run for months. First, Revenue's response to its CGT defeat in [2026] IEHC 59: an appeal to the Court of Appeal would take 18–24 months; a Finance Bill amendment could come as early as October 2026. Second, the CJEU referral on apartment design standards in [2026] IEHC 67: the Irish government has requested priority treatment, but CJEU references typically take 12–18 months. Third, Lightsource Renewable Energy Ireland Limited's overdue annual return: a filing is expected imminently given the commercial significance of the Kilkenny project.

  The Bottom Line
  The most consequential judgment of the week is not the one with the highest financial stakes — it is the CJEU referral on apartment design standards. If the Court of Justice rules that Ireland's guidelines required a Strategic Environmental Assessment, the legal foundation for a significant portion of the apartment pipeline is in question. In a country that needs 50,000 homes per year and is already missing that target, a legal challenge to the design standards that make high-density development viable is not a procedural footnote — it is a potential supply shock.

What to Watch:

Revenue's response to [2026] IEHC 59: appeal or Finance Bill amendment?
CJEU priority ruling on the apartment design SEA referral — expected within 60 days
Lightsource Renewable Energy Ireland Limited annual return filing — now overdue since September 2024
