John is a highly experienced criminal defence practitioner, appearing in both Crown courts and courts martial. He has unique experience as lead counsel acting in historic international criminal tribunals in Sierra Leone and Bangladesh.
John specialises in cases of murder, attempted murder, manslaughter, use and supply of firearms, drugs, and complex sexual offences with an emphasis on vulnerable witnesses.
Recently he has appeared for the defence in nationally reported cases, e.g. the ‘burst football’ manslaughter (R v B and J, recently subject of a Sky TV documentary), the notorious HMP Pentonville escape (R v B), the ‘Epsom Pizza Hut’ kidnap, multiple rape and attempted murder (R v V) and the street-shooting of an Essex drug dealer (R v K) in which the defendant was acquitted.
He has developed a niche practice in the area of vulnerable witnesses and defendants and has lectured on legal developments in this fast-changing area of law and procedure.
International Criminal Practice
In previous years John gained vast experience in international practice. He acted as lead counsel for the former rebel leader Augustine Gbao on trial for war crimes and crimes against humanity at the Special Court of Sierra Leone (2004–09). Uniquely, this case was the first in international legal history to try the use of child soldiers, forced marriage/sexual slavery and the abduction of UN peacekeeping forces, each of which Gbao alone was acquitted.
Having been barred by the Bangladeshi government from acting as lead counsel in situ for several defendants tried for genocide at the international Crimes Tribunal in Dhaka, John advised local defence teams remotely 2011-14 until the eventual conviction and execution of all but one of the defendants.
In late 2013 John travelled as part of a UK Foreign and Commonwealth Office-backed delegation to southern Turkey to advise émigré Syrian law enforcement groups.
John serves on the British Cycling disciplinary panel, notably chairing a tribunal into allegations of serious sexual harassment by a BC coach in 2018.

International Tribunal Experience
The Bangladesh International Crimes Tribunal 2011-2014
A 21ST Century Show Trial
The ICT was instituted by a 1973 Act of the Bangladeshi parliament that aimed to try opposition armed forces personnel in the 1971 Liberation War with Pakistan. Adopting concepts from the Nuremburg trials the legislation was already obsolete according to modern standards. The Tribunal has been widely condemned as politically motivated and lacking in the most basic safeguards of the rights of the accused. It was the first tribunal since 1946 to provide for the death penalty.
The accused were leading members of an opposition Islamic party, Jamaat e Islami, who had held the balance of power in successive governments since independence in 1971. Despite a 38 year delay, the newly-installed Awami League government resurrected the International Crimes (Tribunals) Act in 2009, amending the Bangladeshi Constitution at the same time to curtail the rights of accused persons facing ‘war crimes’ allegations.
As well as trial rights, the Act is silent on the definitions of war crimes and crimes against humanity, rendering it impossible for the defence to address core elements whilst allowing the government-appointed prosecution and judges free rein to mould the law as they chose amidst proceedings that provided for the death penalty.
The Tribunal’s express removal of the rules of evidence and rights to interlocutory appeal, its restriction of client-lawyer access and severe curtailment of the defence right to call witnesses were some of the methods used to ensure expedition of these cases before the 2013 election.
Contrary to the Act’s express provision for instruction of foreign counsel, the government barred John from taking his post in Dhaka, causing him to advise local counsel remotely on a daily basis from the UK. During the trial local defence counsel and witnesses ‘disappeared’, and large quantities of sensitive material were hacked from the UK defence team’s computers. Foreign intelligence sources publicly ‘outed’ the presiding judge’s collusion with the Bangladesh government via hacking devices.
Unable to travel to Dhaka, John regularly travelled to the US, attending meetings at the UN in New York and in the Congressional Houses, the US State Department, the Pentagon and academic establishments in Washington DC advising officials of the wider dangers of these trials at a time of febrile Islamic fundamentalism.
Prosecutor v Augustine Gbao and others, Special Court of Sierra Leone 2004-2009
The RUF Trial: First Ever Indictments re Child Soldiers and Sexual Slavery
The SCSL was set up after a joint agreement between the Sierra Leonian government and the UN to try those ‘bearing the greatest responsibility’ for the 10 year civil war notorious for the Revolutionary United Front (RUF)’s campaign of terror directed at the civil population. By the war’s end in 2002, Gbao was, as Overall Security Commander, one of the RUF’s highest ranking survivors. With his two co-defendants he faced 18 counts of war crimes and crimes against humanity.
Notably, the RUF case made history as the first to try offences of sexual slavery and forced marriage, the abduction of UN peacekeepers, and the use of child soldiers.
The 5 year trial, one of the longest in history, involved more than 250 witnesses ranging from victims and notorious ‘insider’ former combatants to high ranking international and military figures including the former President. Controversial matters arising included the payment of prosecution witnesses, abuse of process concerning the prosecution’s habitual failure to disclose exculpatory evidence, the repetitive addition of prosecution allegations unmentioned in an already unwieldy indictment, and a motion for the recusal of a trial judge for published comments made during the case demonstrating bias against the defendants.
The trial was based in Freetown, a UN ‘hardship post’ amidst hostile conditions where disease and personal safety, poor supply of fuel, power, and water and the constant rumours of armed uprising were ever present. The court’s bureaucratic failings, its inability to properly administer resources and Gbao’s initial refusal to participate exacerbated matters.
As lead counsel John not only conducted all courtroom advocacy but also managed a team including co-counsel, legal assistants and local investigators. Duties ranged from potentially dangerous up-country investigation work to managing the team budget, as well as contributing to various conferences in Freetown and New York attended by high ranking diplomatic personnel from donor countries. John also regularly reported to the Foreign and Commonwealth Office on the trial’s efficacy.
Controversial Application of Joint Criminal Enterprise
The verdicts largely acquitted Gbao both of personal commission and command responsibility of crimes alleged (including use of child soldiers, amputations, sexual offences, forced mining and ordering/participating in the notorious Kailahun mass execution of 1998). The majority of the Trial Chamber, however, convicted Gbao on several counts (with the notable exception of use of child soldiers) via the controversial Joint Criminal Enterprise mode of liability, most of which convictions were subsequently upheld-albeit by a majority-in the Appeals Chamber.
Gbao’s JCE conviction has been widely condemned by commentators and jurists as an abuse of the JCE concept and a setback for international criminal justice. By cynically substituting the mens rea of specific intent for one of reasonable foreseeability in order to convict Gbao on the basic intent mode of JCE liability, the majority of the Trial and Appeal Chambers found Gbao guilty of offences which, according to established JCE law, were impossible for him to commit. The import of this was that JCE was now effectively an offence of strict liability, implying guilt by association.
Fortunately, with the prosecution’s abandonment of JCE in the Taylor case (despite Gbao having been convicted of entering a JCE with Taylor), and recent decisions at the ICC, further misuse of JCE seems to have been curtailed. This was no consolation to Gbao who received 20 years imprisonment.
John was re-assigned as counsel prior to Gbao’s successful application for early release scheduled for June 2020.
