James has over 18 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 of disputes arising out of the energy & natural resources and infrastructure sectors, very often with a connection to Africa, Eastern Europe, the Middle East, Asia, and/or 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 applicable national legislation).

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.
