Ibar McCarthy


Ibar graduated from University College Dublin with a Bachelor of Civil Law and received the Gold Medal for attaining the highest result in his class.

Ibar is a Barrister who was called to the Bar of Ireland in 2011 and the Bar of England and Wales in 2015. Whilst in Ireland, he specialised in commercial litigation, professional negligence, and corporate insolvency and rescue, but dealt in most areas of civil law. He acted in a number of high-profile High Court cases, ranging from a claim brought by a fund against HSBC arising out of the giant Ponzi scheme operated by Bernie Madoff to a claim by a motor dealership who sought to halt the termination of its contract with one of the world’s largest car manufacturers under the Block Exemption Regulation.

After being called to the Bar of England and Wales, he acted as junior to Mark Phillips Q.C. and Michael Crystal Q.C. in AHAB v Saad, which is widely regarded as the most valuable fraud ever litigated and was the longest trial ever to come before the Cayman courts. Judgment was awarded in favour of the liquidators of Saad, Ibar’s clients.

Ibar came back to London in September 2017 and began as a Senior Associate with Joseph Hage Aaronson LLP, where he handled both the FII and CFC & Dividend GLOs, high profile tax litigations that managed two series of like claims for restitution of tax paid by mistake under now repealed legislative provisions on the grounds that they treated UK income more favourably than EU income. Ibar gained extensive UK High Court and Supreme Court experience whilst with JHA.

Ibar joined the firm in June 2019, bringing his experience of group litigation to the Fundão dam case.

Ibar has published on an array of legal areas, regularly appearing in both the Irish Times and the Irish Bar Review. He has appeared in the UK’s tax journal, and whilst at JHA, was accredited with updating and editing Dr Simon Whitehead’s book “The Tax Disputes and Litigation Review”.
