Our team


James Dingley is a Partner and holds over 16 years’ experience of resolving complex, high-value and politically-sensitive disputes. He specialises in international commercial and investment treaty arbitration, and regularly advises as to the implementation and execution of effective risk mitigation strategies. His focus is the efficient resolution of disputes for his clients, whether through formal dispute resolution proceedings or via a negotiated commercial settlement.

James’ clients have consisted of large corporate and financial institutions, States and State-owned entities, and private individuals. He has represented clients in disputes arising out of a wide range of industry sectors, but has particular experience in the energy & natural resources sector, and with a connection to Africa, Eastern Europe, the Middle East, Asia and the wider CIS region. He has acted both in arbitrations conducted pursuant to all major international rules (LCIA, ICC, SIAC, SCC, ICSID Rules and the Energy Charter Treaty), as well as in ad hoc arbitrations (including pursuant to the UNCITRAL Rules, the LMAA Terms and national legislation).

James accepts appointments as an independent arbitrator. He is a member of the panel of arbitrators at the Asian International Arbitration Centre (AIAC) and the Russian Arbitration Centre (RAC).


James started his career in 2006 in the international arbitration practice of a ‘Magic Circle’ law firm, based in London, before leaving in 2020 to establish the London office of an overseas law firm. As a complement to his time in private practice, James also has experience as in-house counsel, having spent time on secondment at both a major international energy company and the U.K. subsidiary of a multinational aerospace and defence conglomerate.


James is a qualified solicitor of the Supreme Court of England & Wales and was admitted to the roll in 2006. He is a Member of the Chartered Institute of Arbitrators and was named as a “Rising Star” of international arbitration by the U.K. Legal 500 in 2021. James received his MA from Balliol College, Oxford, where he read Modern Languages. He is fluent in English, French, German and speaks basic Russian.
