Background
Ronan O’Brien, a solicitor admitted in 2009 and practising as Ronan O’Brien & Company Solicitors in Cavan, was the subject of a complaint by two clients to the Legal Services Regulatory Authority. The LSRA referred the matter to the Law Society, which conducted an investigation and obtained an order suspending O’Brien from practice on 29 April 2024. The Society then applied to the Legal Practitioners Disciplinary Tribunal (LPDT) for a formal inquiry under the Legal Services Regulation Act 2015.
The Tribunal held inquiry hearings across three dates in 2025. At the first hearing, O’Brien appeared and admitted the majority of allegations against him. The admitted allegations included: misappropriating €239,500 from the client account of William and Lorraine Kehoe to fund property acquisitions; causing multiple unauthorised deficits on client ledgers totalling several hundred thousand euros; failing to maintain proper books of account; failing to produce vouching documentation for payments from client accounts; and failing to document client risk assessments as required by the Solicitors (Money Laundering and Terrorist Financing) Regulations 2020. O’Brien did not appear for either of the two subsequent hearings convened to address sanction, despite the Tribunal being satisfied he was aware of both dates.
The Tribunal issued its Determination and Recommendation on 14 October 2025, finding misconduct proven on all outstanding allegations under ss. 50(1)(a) (fraud or dishonesty), 50(1)(e) (breach of the Solicitors Acts and regulations), and 50(1)(h) (conduct likely to bring the profession into disrepute) of the 2015 Act. The Tribunal recommended that the High Court strike O’Brien from the Roll of Solicitors and order him to pay the Society’s Tribunal costs of €10,114.50. The Society then applied to the High Court under s. 85 of the 2015 Act to give effect to that recommendation. O’Brien did not appear and, while service by registered post was returned undelivered, the court was satisfied that service had been properly effected by email to an address he had previously used in related High Court proceedings.
The Court’s Holding
Barniville P, President of the High Court, struck Ronan O’Brien’s name from the Roll of Solicitors pursuant to s. 85(7)(f) of the Legal Services Regulation Act 2015. The court was satisfied that the Tribunal had applied the correct legal principles in reaching its determination and recommendation, as established by Kelly P in Law Society v D’Alton [2019] IEHC 177 and confirmed by the Supreme Court in Law Society v Coleman [2018] IESC 80. While the court is not bound by the Tribunal’s recommendation and is the ultimate arbiter of sanction, it found the recommendation of strike-off to be appropriate, proportionate, and consistent with the authorities on dishonesty.
The court emphasised that findings of misconduct involving dishonesty — and particularly the misappropriation of client funds — will almost invariably result in strike-off. Barniville P drew on the line of authority from Bolton v Law Society [1994] 1 WLR 512 through Re Burke [2001] 4 IR 445, Law Society v Carroll [2016] 1 IR 676, and Law Society v Doocey [2022] IECA 2, affirming that honesty is a core value of the solicitors’ profession and that departures from honest conduct attract the most serious sanctions. The aggravating factors identified by the Tribunal — that the conduct was dishonest, calculated, repeated, followed by attempts at concealment, financially beneficial to O’Brien at clients’ expense, and accompanied by two prior disciplinary findings — rendered strike-off the only proportionate outcome.
The court also ordered O’Brien to pay the Society’s measured Tribunal costs of €10,114.50 pursuant to s. 85(7)(h)(iii) and the Society’s costs of the High Court application, measured at €3,978, pursuant to s. 85(8) of the 2015 Act.
Key Takeaways
- Misappropriation of client funds constitutes misconduct under s. 50(1)(a) of the Legal Services Regulation Act 2015 and will almost invariably result in strike-off from the Roll of Solicitors, regardless of mitigating circumstances such as personal difficulties or cooperation with the inquiry.
- The High Court is the ultimate arbiter of sanction under the 2015 Act disciplinary regime and is not bound by the Tribunal’s recommendation, but will afford it significant weight where the Tribunal has correctly applied the relevant legal principles on sanctioning (public protection, professional reputation, punishment, deterrence, and proportionality).
- Aggravating factors — including calculated and repeated dishonesty, personal financial benefit at clients’ expense, attempts to cover up wrongdoing, and prior disciplinary findings — can render strike-off the only proportionate sanction irrespective of any mitigation offered.
- Service of court proceedings by email to an address previously used by a respondent in related proceedings can constitute valid service where registered post is returned undelivered.
Why It Matters
This decision reinforces the Irish courts’ unwavering approach to solicitor dishonesty: where client funds are misappropriated, the default sanction is removal from the profession. The judgment applies and consolidates the post-Coleman framework under the Legal Services Regulation Act 2015, confirming that the D’Alton five-factor test for sanctioning (public protection, professional reputation, punishment, deterrence, proportionality) governs High Court proceedings under the new regime in exactly the same way as it did under the prior statutory framework.
For regulators and practitioners, the case illustrates the cumulative weight of aggravating factors — prior findings, concealment, personal enrichment — in disciplinary proceedings, and signals that neither personal hardship nor cooperation at an inquiry stage will outweigh serious, repeated dishonesty. It also serves as a procedural reminder that a respondent who fails to engage with sanction hearings before the Tribunal, and then fails to appear before the High Court, will not thereby delay or avoid the most serious consequences of a misconduct finding.
