John has appeared for the defence in nationally reported cases – from the 2017 ‘burst football’ manslaughter (R v Bollen and Jelly) to the HMP Pentonville escape (R v Baker); and from the ‘Epsom Pizza Hut’ kidnap, multiple rape and attempted murder (R v Voedes) to the street-shooting of an Essex drug dealer (R v Kenny) in which the defendant was acquitted.

He has also developed a niche practice in the area of vulnerable witnesses and defendants.

He is also a CPS Grade  3 prosecutor and also on the rape list.

International criminal practice

In previous years John gained unique experience in international practice, acting as lead counsel for a former rebel leader on trial for war crimes and crimes against humanity at the Special Court of Sierra Leone (2004–09), and as adviser to local defence teams for several defendants tried at controversial Bangladesh International Crimes Tribunal (2011–14). In late 2013 John travelled to southern Turkey to advise émigré Syrian law enforcement groups.

John has lectured and trained in the law, procedure and practice within international criminal tribunals and procedure here and abroad. He has lectured at the American Society of International Lawyers in Washington DC and at St Antony’s College Oxford. He has advised the UK Foreign and Commonwealth Office (FCO), the US State and Defense Departments and the Nigerian National Security Advisor.

He also has appeared regularly on TV and radio, and written extensively in publications from Counsel to the New York Times.

Notable cases

R v B, 2017
Baker, awaiting sentence for attempted murder, was charged with the common law offence of breaking prison as one of two men who escaped from HMP Pentonville.
