Acting for some of the world's largest commodity and natural resources companies, John specialises in trading disputes, international economic sanctions and advisory work in relation to a wide range of international trading issues including anti-bribery, corruption, anti-money laundering and compliance. Having worked in this area for over 20 years, John regularly leads internal corporate investigations which arise where potential violations have occurred or where violations are alleged, for example, in a whistleblowing scenario or where law enforcement agencies have started their own investigations. He also acts for and against Governments in relation to contractual issues, investment disputes and sovereign immunity.

John's practice is recommended in various editions of the legal directories Legal 500 and Chambers UK for commercial litigation, international arbitration, public international law and commodities.  Market sources describe him as "very practical" and speak highly of his "great strategic overview". (Chambers 2014). In the context of Public International law, John is described as "extremely knowledgeable" (Legal 500, 2014)

John has handled cases before Courts in the UK and abroad, including a number of cases in Russia and Eastern Europe where he has extensive experience, having spent a substantial part of his career there. A representative of the Serbian Government praised "his understanding of the local circumstances and political sensitivities of the case... the Serbian Government received value for money" (Global Arbitration Review, GAR 100 2014).

John regularly speaks at high profile conferences, particularly on sanctions and anti-money laundering and bribery, including:

  • Metal Bulletin Events’ Annual International Aluminum Conference;
  • The FT Global Commodities Summit; and
  • Insider Intelligence Anti-Corruption in Oil & Gas.
