Gillian Higgins

Head of the International Practice Group

 BACKGROUND AND EXPERTISE

Gillian is a senior international criminal lawyer and Head of the International Practice Group with extensive experience at the International Criminal Court (ICC) and the UN international tribunals. She has been instructed in some of the leading cases in international criminal law including the first trial of a former Head of State (former President of Serbia, Slobodan Milosevic) and the first case at the ICC of an incumbent Head of State (President Uhuru Kenyatta of Kenya). Before the International Criminal Tribunal for the Former Yugoslavia, she represented Ivan Cermak in a case that has been described as the most important trial in the history of Croatia. Before the Rwanda Tribunal (ICTR), she acted for the defence in the trials of Alfred Musema (the first trial of a civilian alleging command responsibility for genocide) and Ferdinand Nahimana (a trial concerning the responsibility of the media for genocide in Rwanda in 1994). In 2019, she was appointed as an independent commissioner to the Special Tribunal for Lebanon. Gillian is currently advising the Government of South Sudan on international legal issues. She also provides interactive Witness Familiarisation sessions for both experts and witnesses of fact in any legal forum. These sessions include cross-examination experience and are intended to give individuals confidence in giving evidence in legal proceedings.

In 2023, Gillian launched the Cultural Heritage Desk which she leads at 9BR Chambers. She provides legal services and lends her mediation and negotiation skills to resolving issues arising in this field including cultural restitution. She also reviews publications in this field for Oxford University Press. See here.

The Prosecutor v Uhuru Kenyatta, 2010–15

International Criminal Court proceedings commenced in December 2010 against President Uhuru Kenyatta of the Republic of Kenya, and son of the first President of the nation, Jomo Kenyatta. The case alleged that President Kenyatta had a leading role in the post-election violence of 2007-2008 for which he was charged with crimes against humanity. At the confirmation of charges hearing the Defence challenged the prosecution's case theory comprehensively and called Uhuru Kenyatta to give evidence in his own defence. Although the Pre-Trial Judges confirmed the charges, it was subsequently established that the defence contentions at the confirmation hearing had been correct. In January 2015 the charges were finally withdrawn by the Prosecution, having admitted there was an insufficiency of evidence upon which to proceed to trial. Read the Defence report here.
