Three judgments in one week: Ireland's biggest corporate espionage case escalates as data centre planning battle is settled

The Irish High Court delivered 0 judgments in March 2026, with the week of 12–16 March anchored by a landmark data centre planning ruling and framed by a flurry of corporate litigation that followed. The Rippling v Deel corporate espionage saga — involving a $17bn HR tech giant, a Dublin-based alleged spy, and Revolut payment records — produced three separate High Court judgments on a single day (20 March), while Humphreys J. upheld planning permission for a Clare data centre on 13 March in a ruling that will reverberate through Ireland's energy and infrastructure debate.

  Business Post AI Pick: The Spy in the Machine
  Three High Court judgments on a single day in the Rippling v Deel case is not routine case management — it signals a case that has grown too complex for sequential hearings. Keith O'Brien, the former Rippling employee at the centre of the alleged espionage, has now settled with Rippling, agreed a cooperation agreement, and received €80,000 toward legal costs — yet the litigation continues to expand. The so-what: when a $17bn company is fighting a corporate espionage case in the Irish courts, the jurisdiction matters. Ireland is where the alleged spy worked, where the surveillance happened, and where the Revolut payment trail leads.

Pattern of the Week: Data Centres and the Courts The Doyle v An Coimisiún Pleanála ruling on 13 March is the third No. in this case series — a sign that data centre planning challenges are becoming multi-year litigation events. Humphreys J. dismissed challenges on climate change, bat fauna, and EIA grounds. The pattern: environmental groups are testing every available legal avenue, and the courts are consistently upholding planning decisions where conditions (including renewable energy CPPAs) are attached.

This Week's Cases: Corporate Espionage, Planning Battles, and a Winding-Up Refused

The week of 12–16 March 2026 produced one judgment in the exact window — the data centre planning ruling on 13 March — but the surrounding days delivered a concentrated burst of commercially significant litigation. Taken together, the cases reveal three dominant themes in the Irish courts this spring: the escalating Rippling v Deel corporate espionage saga, a consistent pattern of planning permission being upheld against environmental challenge, and a High Court willing to exercise discretion against creditors in insolvency petitions where the company has viable assets and employees to protect.

Key Cases: 12–20 March 2026

Citation	Parties	Type	Outcome	Signal
[2026] IEHC 156	Doyle v An Coimisiún Pleanála [No.3]	Planning	Data centre permission upheld. Clare CC. CPPAs required.	Permission stands
[2026] IEHC 178	Rippling v O'Brien & Ors [No.1]	Corporate	Joinder of Deel execs (Bouaziz, Mieli, Malik) set aside. Sanfey J.	Deel wins round
[2026] IEHC 179	Rippling v O'Brien & Ors [No.2]	Corporate	Para 30 struck out. Paras 54 & 67 survive. Defamation pleadings trimmed.	Mixed
[2026] IEHC 180	Rippling v O'Brien & Ors [No.3]	Corporate	Termination Agreement: limited disclosure to confidentiality ring only.	Confidentiality
[2026] IEHC 167	Grant Thornton v Scanlan	Confidence	Permanent injunctions granted. Data Protection counterclaim dismissed.	GT wins
[2026] IEHC 172	ER Travel v DAA PLC	Competition	7-year case proceeds without unavailable expert. Barrett J.	Ongoing
[2026] IEHC 161	Linley Investments (Coolmore) v Riley	Bloodstock	Decree €208k. Stud fees + maintenance. Charleton J.	Riley liable
[2026] IEHC 140	Charles Kelly Limited v Companies Act	Insolvency	Winding-up petition refused. 23 employees. Asset-rich. Charleton J.	Company survives

Stress Signal: Rippling v Deel — The Litigation Keeps Expanding Three judgments in a single day is the clearest possible signal that the Rippling v Deel case has entered a new phase of complexity. Sanfey J. set aside the joinder of Keith O'Brien's alleged co-conspirators (Bouaziz, Mieli, Malik) on the grounds that no live issues remained between Rippling and O'Brien at the time of joinder — a procedural win for Deel. But the substantive allegations — corporate espionage, Revolut payments, surveillance — remain very much alive. The so-what: Deel has won a battle, not the war. The case continues in both Dublin and US courts simultaneously.

Standout: Data Centre Green Light in Clare Humphreys J.'s dismissal of the Doyle v An Coimisiún Pleanála challenge is the third consecutive ruling in this case series upholding the data centre permission. The court found that conditions requiring corporate power purchase agreements (CPPAs) for renewable energy were sufficient to address climate concerns, and that a bat derogation licence was not required before permission could be granted. For data centre developers and their legal teams, this is a significant precedent: the courts are not requiring pre-permission resolution of every environmental concern, provided conditions are attached.

The Connections: What the Judgments Reveal About Irish Business

Court data alone tells you who won and who lost. Cross-referencing it with CRO records, Business Post coverage, and property data tells you why it matters. This week's cases connect across three distinct business themes: the vulnerability of tech companies to internal espionage, the courts' consistent support for infrastructure development, and the High Court's growing willingness to protect employment over creditor rights in insolvency proceedings.

The Revolut Trail: How a $6,000 Payment Became a $17bn Legal Battle The Business Post reported in November 2025 — in Rippling alleges new Revolut records prove payment was made to 'spy' — that newly unsealed documents showed a $6,000 transfer from Deel's corporate account, via the COO's wife, to Keith O'Brien's account. Three months later, three High Court judgments in a single day confirm the case has not slowed down — it has accelerated. CRO records show O'Brien was a director of Coleus Consulting Limited (Airside, Swords) from October 2017 to June 2021 — the same period he was employed at Rippling's Dublin office. The so-what: O'Brien was not a casual employee. He was a director of an Irish consulting company, a person with corporate standing in Ireland, and the alleged spy at the centre of a case that now involves the CEO of a $17bn company. Ireland's courts are the venue for a global tech espionage dispute because that's where the evidence trail leads.

Infrastructure Watch: Courts Consistently Back Data Centre Permissions The Doyle v An Coimisiún Pleanála [No.3] ruling on 13 March is the third in a series upholding the same Clare data centre permission. Humphreys J. has now dismissed challenges on climate change, EIA, bat fauna, and ETS grounds. The pattern across March 2026 is consistent: the court is upholding planning decisions where conditions are attached, and is not requiring developers to resolve every environmental concern before permission is granted. For Ireland's data centre sector — which accounts for 21% of national electricity consumption — this is a significant signal. The question for the next planning cycle: will the CPPA conditions attached to this permission become the template for all future data centre approvals?

Confidence in Confidence: Grant Thornton Wins, but the Lesson is Broader Grant Thornton Business Advisory Services Limited (13-18 City Quay, Dublin 2 — CRO company 91353, registered 1982, last accounts 31/12/2024) won permanent injunctions in [2026] IEHC 167 after a CD containing confidential client data was sent to the wrong recipient. The defendant retained, copied, and disclosed the data to third parties — and then counterclaimed under the Data Protection Act. Dignam J. dismissed the counterclaim for lack of evidence of damages. The so-what: this case is a warning to every professional services firm in Ireland. Accidental disclosure of confidential data does not transfer ownership of that data to the recipient. The recipient's duty of confidence arises the moment they become aware of the nature of the information — and the courts will enforce it.

Insolvency Discretion: The Court Protects Jobs Over Creditors The refusal to wind up Charles Kelly Limited in [2026] IEHC 140 is a reminder that the High Court retains broad discretion in winding-up petitions. Charleton J. refused the petition despite a €1,000,738 judgment debt for unpaid legal fees, noting the company was asset-rich, had 23 employees in Donegal builders' supplies, and that judgment mortgages already secured much of the debt. The so-what: a winding-up petition is not an automatic remedy for a judgment creditor. Where a company has viable assets, ongoing employment, and alternative means of satisfying the debt, the court will look for a proportionate solution. Solicitors seeking to enforce fee judgments through winding-up should note this precedent carefully.

The Radar: Three Signals Worth Watching

Signal 1: Corporate Espionage as an Irish Legal Phenomenon The Rippling v Deel case is not an isolated incident. It follows a pattern of global tech companies using the Irish courts to resolve disputes that originate in Silicon Valley but involve Irish-based employees. The case involves Keith O'Brien (Celbridge, Co. Kildare), Coleus Consulting Limited (Swords), and Revolut (Dublin-headquartered). Three separate jurisdictions, one Irish courtroom. Watch for: whether the Irish courts develop a specific framework for cross-border corporate espionage cases, or whether this remains ad hoc litigation under existing commercial law.

Signal 2: The Seven-Year Competition Case Against DAA ER Travel v Dublin Airport Authority has been running since 2019 — seven years. Barrett J. refused an adjournment when the plaintiff's expert economist became unavailable, ordering the trial to proceed on existing expert reports. This is a significant case management decision: the court is prioritising finality over the plaintiff's preferred mode of presenting evidence. Watch for: the substantive competition law issues in this case, which concern DAA's commercial practices at Dublin Airport. A finding against DAA could have significant implications for airport commercial arrangements across Ireland.

Signal 3: Bloodstock Disputes and International Defendants The Coolmore v Riley case involves Nigel Riley, a defendant with connections to South Africa and Israel, and a dispute over stud fees and horse maintenance at Cork stud farms. Charleton J. awarded €208,000 to Coolmore and Coolagown. The so-what: Ireland's bloodstock industry — one of the most valuable agricultural sectors in the country — is increasingly dealing with international clients who dispute fees and maintenance obligations. Watch for: whether the Coolmore decree can be enforced against an international defendant, and whether this case prompts the bloodstock industry to adopt more formal contractual frameworks for international clients.

The Deep Dive: Two Cases That Define the Week

Two cases from this period deserve extended treatment: the Rippling v Deel corporate espionage saga, which produced three judgments in a single day and represents the most complex commercial litigation currently before the Irish courts, and the Charles Kelly Limited winding-up refusal, which illustrates a quieter but equally important principle — that the High Court will protect viable businesses and their employees even when creditors have a legitimate judgment debt.

Rippling v Deel — Ireland's Biggest Corporate Espionage Case

People Centre Inc (trading as Rippling) is a San Francisco-based HR and payroll software company with a significant Irish presence. Its rival, Deel Inc, is valued at $17bn following a $300m Series E fundraise in October 2025. The case centres on allegations that Deel recruited Keith O'Brien, a Rippling employee based in Dublin, to spy on Rippling's internal systems — accessing Slack, Salesforce, and Google Drive — and pass sensitive competitive intelligence to Deel. O'Brien admitted destroying his phone with an axe while hiding in a toilet cubicle. He has since settled with Rippling, signed a cooperation agreement, and received €80,000 toward legal costs.

Judgment	Date	Issue	Outcome
[2026] IEHC 178	20 Mar 2026	Joinder of Deel executives	Set aside. No live issues between Rippling and O'Brien at time of joinder.
[2026] IEHC 179	20 Mar 2026	Strike out of pleadings	Para 30 struck (not defamatory). Paras 54 & 67 survive. Deel wins partial.
[2026] IEHC 180	20 Mar 2026	Termination Agreement disclosure	Limited disclosure to confidentiality ring only. Rippling's position protected.
US proceedings	Ongoing	Parallel US litigation	Case runs simultaneously in US and Irish courts.
CRO cross-reference	2017–2021	Coleus Consulting Ltd	O'Brien was director of Coleus Consulting (Airside, Swords) during Rippling employment.

  Reading Between the Lines: Deel Wins Battles, Not the War
  Sanfey J.'s three rulings on 20 March are procedural wins for Deel — the joinder of its executives was set aside, one defamatory paragraph was struck, and the Termination Agreement will only be disclosed to lawyers. But none of these rulings touch the substantive allegations: that Deel orchestrated corporate espionage through a Dublin-based employee, that Revolut records show a $6,000 payment trail, and that Deel ordered surveillance of O'Brien after he became a witness. The so-what: Deel has bought time and limited exposure, but the core case — corporate espionage, conspiracy, and the Revolut payment — remains fully alive. The question for the next hearing: will Deel's procedural victories translate into substantive defences, or are they delaying tactics in a case where the evidence trail is already public?

The question for the next hearing: will Sanfey J.'s case management approach — three judgments in one day, tight control of disclosure — accelerate the case toward a full trial on the merits, or will further procedural applications continue to delay the substantive hearing?

Charles Kelly Limited — When the Court Says No to a Winding-Up

Charles Kelly Limited is a builders' supplies company based in Letterkenny, Co. Donegal, with 23 employees and a history that includes NAMA and Ulster Bank exposure. Solicitors Peter and Melanie Boyle petitioned to wind it up over a €1,000,738 judgment debt for unpaid legal fees. Charleton J. refused the petition.

Factor	Detail	Weight
Judgment debt	€1,000,738.40 (unpaid legal fees)	Against company
Employees	23 staff in Donegal builders' supplies	For company
Asset position	Asset-rich; judgment mortgages already registered	For company
NAMA / Ulster Bank	Historical exposure; company survived both	Context
Court's finding	Winding-up disproportionate; alternatives available	Company survives

Why It Matters: The Discretion Principle in Action Charleton J.'s refusal in [2026] IEHC 140 is a textbook application of the court's discretion in winding-up petitions. The Companies Act 2014 gives the court power to refuse a winding-up order even where a company is technically insolvent, if the court considers it just and equitable to do so. Here, the company was asset-rich, had 23 employees in a regional economy, and the petitioners already had judgment mortgages securing much of the debt. The so-what: this is not a case about protecting a failing company — it's about proportionality. The court found that destroying 23 jobs and a viable business to satisfy a legal fee debt, when other enforcement mechanisms were available, was not a proportionate response.

The question for the next period: will the Boyle solicitors pursue enforcement through the judgment mortgages, or will Charles Kelly Limited's management finally address the underlying debt that has been outstanding long enough to generate a €1m legal fee dispute?

One to Watch: Grant Thornton Business Advisory Services Limited

Grant Thornton Business Advisory Services Limited

CRO No. 91353 • 13-18 City Quay, Dublin 2, D02 ED70 • Registered 15 September 1982 • Last accounts: 31/12/2024 • Status: Normal

Metric	Detail
Company type	LTD — Private Company Limited by Shares
Registered	15 September 1982 (44 years in operation)
Address	13-18 City Quay, Dublin 2 (D02 ED70)
Last accounts filed	31 December 2024
Court case	[2026] IEHC 167 — Permanent injunctions granted

Grant Thornton Business Advisory Services Limited is the Irish operating entity of the Grant Thornton international professional services network. Based at City Quay, Dublin 2, it provides audit, tax, and advisory services to Irish and international clients. The firm has been registered in Ireland since 1982 and filed accounts to 31 December 2024.

Why it matters: the firm's victory in [2026] IEHC 167 establishes a clear precedent for professional services firms across Ireland. When confidential client data is accidentally disclosed, the recipient has an immediate duty of confidence — and the courts will grant permanent injunctions to enforce it. The defendant's attempt to counterclaim under the Data Protection Act was dismissed for lack of evidence of damages. The so-what: this is not just a Grant Thornton win. It's a precedent that every law firm, accountancy practice, and financial services firm in Ireland can rely on when confidential data goes astray.

The number that matters: zero — the amount of damages the defendant was awarded on the Data Protection counterclaim. The court found no evidence of actual damage from the accidental disclosure, despite the defendant's retention and copying of the data. Watch for: whether this judgment prompts professional services firms to update their data incident response protocols to include immediate legal action rather than relying on voluntary return of data.

The Broader Picture

The Companies Registration Office

The CRO context for this week's litigation is instructive. Grant Thornton Business Advisory Services Limited (CRO 91353) has been registered since 1982 and filed accounts to 31 December 2024 — a firm with deep institutional roots in Irish professional services. Coleus Consulting Limited (CRO 601193), the Swords-based company where Keith O'Brien served as director from 2017 to 2021, is a staffing and consulting company at Airside Business Park — the kind of Irish corporate vehicle that underpins the tech sector's contractor economy. The Rippling v Deel case is not just a Silicon Valley dispute: it runs through the Irish corporate registry, through a Kildare address, and through a Swords consulting firm. 0 new companies were registered in Ireland in March 2026, and 193 new business names were filed — the backdrop against which this week's litigation plays out.

Entity	CRO No.	Status	Relevance
Grant Thornton Business Advisory Services Ltd	91353	Normal	Plaintiff in breach of confidence case. Permanent injunctions granted.
Coleus Consulting Limited	601193	Normal	CRO company linked to Keith O'Brien (director 2017–2021). Airside, Swords.
Rippling Ireland Limited	N/A	No CRO match	US-headquartered. Still actively hiring in Ireland as of April 2026.
Charles Kelly Limited	N/A	No CRO match	Donegal builders' supplies. 23 employees. Winding-up petition refused.

Property Markets & Plans

Dublin's commercial property market recorded 615 transactions in March 2026, with an average price of €562,394 and a median of €440,528. The standout transaction in the period was 7-8 Grafton Street, Dublin 2, which transacted at €757,706 on 11 March — a prime city centre commercial unit changing hands at a price consistent with the continued resilience of Dublin's retail core. The data centre planning ruling in Clare on 13 March adds a further dimension: the courts are clearing the legal path for infrastructure investment at the same time as commercial property in Dublin continues to trade at elevated levels.

Address	Amount	Date	Type
7-8 Grafton Street, Dublin 2	€757,706	11 Mar 2026	Commercial
Unit 4 and 4b Kylemore Park North, Dublin 10	€54,000	11 Mar 2026	Commercial
23a Second Avenue, Cookstown Ind. Estate, Dublin 24	€75,000	10 Mar 2026	Commercial
459 South Circular Road, Dublin 8	€24,000	13 Mar 2026	Commercial
Unit 134 Slaney Close, Dublin Industrial Estate, Glasnevin	€95,000	6 Mar 2026	Commercial

  Infrastructure and Investment: Two Sides of the Same Coin
  The data centre planning ruling in Clare and the commercial property transactions in Dublin are not unrelated. Ireland's position as a European data centre hub depends on both legal certainty (which the courts are providing) and commercial property availability (which Dublin's market continues to supply). The €29m maximum transaction recorded in Dublin in March 2026 — against a median of €440k — suggests a market with significant depth across the commercial spectrum. Watch for: whether the Clare data centre CPPA conditions become a model for planning conditions across the sector, and whether Dublin commercial property continues to hold value as data centre demand for power infrastructure grows.

The Week Ahead

The week of 12–16 March 2026 will be remembered in Irish legal circles for two things: the data centre planning ruling that cleared the path for Clare's infrastructure investment, and the corporate espionage case that put Ireland at the centre of a global tech dispute. The Rippling v Deel saga is far from over — three judgments in one day is a sign of acceleration, not resolution. The Charles Kelly winding-up refusal is a reminder that the High Court's discretion in insolvency matters is real and consequential. And the Grant Thornton breach of confidence ruling is a precedent that will be cited in professional services disputes for years to come.

  The Bottom Line
  Ireland's courts are doing three things simultaneously this spring: clearing the legal path for data centre infrastructure, managing the most complex corporate espionage case in the state's history, and protecting regional employment from disproportionate creditor action. Each of these reflects a different dimension of Ireland's economic identity — as a data infrastructure hub, as a tech employment base, and as a country where the courts still exercise meaningful discretion in commercial disputes. The single most important takeaway from this period: the Rippling v Deel case is not a curiosity. It is a test of whether Ireland's commercial courts can handle the complexity of global tech litigation — and so far, they are passing.

What to Watch:

The next Rippling v Deel hearing — will Sanfey J. set a trial date, or will further procedural applications delay the substantive case?
The ER Travel v DAA competition case — seven years in, the substantive hearing is now proceeding. A finding against DAA could reshape airport commercial arrangements.
The Coolmore v Riley enforcement question — can a €208k decree be enforced against a defendant with South Africa and Israel connections? The bloodstock industry is watching.
