Practice Areas

Ben has acted in some of the most high profile international criminal cases of the last decade, in particular before the International Criminal Court. He represents and conducts advisory work on behalf of governments, organisations and individuals. The international nature of his practice demands that he is comfortable operating in adversarial and inquisitorial systems.

Experienced operating in hostile conditions, he conducts sensitive defence investigations with care and precision. In both Kenya and Cambodia, Ben interviewed sensitive witnesses and provided legal assistance to police, military and communications experts. He has worked closely with intelligence professionals on the collection and analysis of complex financial and communications evidence.

Ben represents individuals and organisations in cases involving violations of international human rights law. He has developed particular expertise in respect of a number of regional tribunals, including the European Court of Human Rights, Court of Justice of the European Union, African Court on Human and Peoples’ Rights, the African Commission on Human and Peoples’ Rights and the Southern African Development Community Tribunal. Ben has significant experience conducting capacity building projects overseas.

Ben is a specialist extradition practitioner. He regularly represents individuals and requesting States in contested extradition hearings before Westminster Magistrates’ Court and on appeal before the High Court.

INTERNATIONAL CRIME NOTABLE CASES

Ben was a long-term member of the defence team that represented Uhuru Kenyatta, the President of Kenya, before the ICC. Ben played a key role in laying bare the investigative flaws in the Prosecution’s case that eventually led to the withdrawal of all charges and the termination of the case against President Kenyatta by Trial Chamber V(B) in 2015
