Practice notes

Jonathan is a partner in our Dispute Management practice group in London and specialises in international arbitration. He has over 17 years’ experience of advising and representing companies, banks and States in connection with disputes arising in various industry sectors, in particular energy and natural resources, international trade, transportation and financial services. He has handled commercial and investor-State arbitrations under all the major institutional rules.

Jonathan is a Fellow of the Chartered Institute of Arbitrators and a qualified advocate before the Higher Courts of England & Wales and the Singapore International Commercial Court. Prior to joining Eversheds, he trained and worked at Hogan Lovells in London and Singapore, where he led that firm’s SE Asia international arbitration practice.

Jonathan is ranked as a leading arbitration practitioner and recently described as “in the premier league. His easy-going manner disguises the fact that he is able to untangle the most complex disputes” (Chambers, 2016) and “intellectually very strong, with excellent analytical skills” (Legal 500, 2015).

His experience includes acting for:

  • Finnish manufacturer in ICC arbitration against a Malaysian company arising from the breakdown of a joint venture for the manufacture of microprocessor applications.
  • Singapore-based engineering company in ICC arbitration against multi-national energy company relating to the supply and installation of pipes for a major oil and gas project.
  • Omani company in dispute subject to the SIAC Rules regarding the enforcement non-compete provisions in a joint venture agreement with an Indian group.
  • New Zealand-based trust services regarding debts allegedly owed under a management service agreement for a clinic in Switzerland.
  • The Republic of Vietnam in three separate UNCITRAL arbitrations brought by foreign investors under investment treaties.
