Ian McDonald
Call: 2017
Practice Overview
Ian is a leading junior with a broad practice, particularly focused on commercial litigation, international arbitration, public international law, international human rights law, and private international law. He is regularly instructed in complex, high-value cases, often with an international dimension.
The legal directories describe Ian as “an absolute star”; “extremely clever and diligent”; and “quickly establishing himself as one of the best juniors” at the Bar. He has been praised for his “clear and to-the-point” written style and treatment and assessment of evidence; his “careful and responsive”, “cooperative”, and “calm” approach; and his communication skills.
Ian is ranked in the Legal 500 (2026) as a leading junior in each of his four main practice areas: commercial litigation, international arbitration, public international law, and international human rights law.
Ian has substantial commercial litigation experience, including in civil fraud disputes. He is acting for Nick Candy’s investment firm in its multi-million-pound fraud claim against the failed tech start-up, Aaqua, and its founder Robert Bonnier, and their counterclaim for damages allegedly caused by the granting of WFOs (Candy Ventures sarl v. Aaqua & Ors). Ian also represented Nick Suppipat and his companies in their fraud claims against multiple defendants in the Commercial Court, in which judgment was handed down – following a 20-week trial – for damages of over US$850 million (Suppipat & Ors v. Narongdej & Ors). And he acted in Discovery Land Company LLC & Ors v. AXIS, a multi-million-pound Commercial Court dispute arising out of a former solicitor’s fraudulent misconduct.
Ian is routinely instructed in international commercial and investment arbitrations, including under the UNCITRAL, ICC, and LCIA Rules and the ICSID Convention. He was part of the 3VB Counsel team that advised Chevron in a landmark ICC arbitration that cleared the way for Chevron’s US$53 billion merger with Hess Corporation. Ian also recently represented a Central American entity in an arbitration under the ICC Rules against an energy company in respect of a US$70 million-plus claim relating to the provision of power to a Caribbean state. And he acted for the claimant energy company in an LCIA arbitration in connection with a renewable energy project in eastern Europe.
Ian is developing a broad practice in public international law, representing states, foreign investors, companies, and individuals. He is currently acting for a Turkish investor in significant investor-state arbitral proceedings under the ICSID Convention, alleging breaches of fair and equitable treatment and unlawful expropriation (Güriş İnşaat v. Kingdom of Saudi Arabia); and for an investor in the Far East in a substantial investor-state claim against a foreign state, pursuant to the UNCITRAL Rules, again alleging violations of fair and equitable treatment and unlawful expropriation.
Ian has significant experience in international human rights law and is regularly instructed in applications to the European Court of Human Rights; petitions to the UN Working Group on Arbitrary Detention; communications to the UN Human Rights Committee; and submissions to other Special Procedures of the UN Human Rights Council. He was part of the 3VB Counsel team that represented the British-Egyptian writer and pro-democracy activist, Alaa Ahmed Seif al Islam Abd el-Fattah, before the UN Working Group on Arbitrary Detention, successfully challenging his detention in Egypt. Ian also acted for the Moscow bureau of the international media group RFE/RL and its general director in their application to the European Court of Human Rights, challenging the use of ‘foreign agent’ laws against them (Radio Free Europe/Radio Liberty LLC & Anor v. The Russian Federation).
Ian has particular interest and expertise, too, in private international law. His recent experience includes advising a foreign company in relation to discrete conflict of laws issues arising in a long-running and high-value dispute before the Chancery Division of the High Court, concerning an alleged unlawful means conspiracy; and successfully resisting a jurisdiction challenge in another multi-million-pound unlawful means conspiracy claim (VP Fund Solutions (Luxembourg) SA v. GI Globinvestment Ltd). Ian has also worked as a teaching assistant on the Conflict of Laws module on the Bachelor of Civil Law at the University of Oxford.
As well as acting as a junior in led matters, Ian has considerable experience as an advocate, having been instructed as sole Counsel in a range of cases and regularly appearing in his own right at interim and final hearings in the High Court and County Court.
