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 In January 2015 the charges were finally withdrawn by the Prosecution, having admitted there was an insufficiency of evidence upon which to proceed to trial.
