Last month, the Kenya National Commission on Human Rights (KNCHR) [advocacy website], which implicated former Cabinet minster William Ruto of interfering with the ICC investigation, denied accusations that it had bribed witnesses [JURIST report]. Two witnesses, Ken Braziz Wekesa and William Kepkemboi Rono, claimed they were bribed by the KNCHR [Daily Nation report], a government-funded human rights group, to testify to the ICC against Ruto, the former higher education minister. Moreno-Campo said that the court will not use testimony [JURIST report] from three Kenyan witnesses who claim they were bribed to provide false evidence against a high-ranking government official. In September, Kenyan businessman Joseph Gathungu filed a lawsuit challenging the constitutionality [JURIST report] of the ICC investigation into the violence following the 2007 Kenyan presidential election. The suit, which was filed in the High Court [GlobaLex backgrounder] in Mombasa, argues that the ICC investigation is illegal under the constitution adopted last month [JURIST report]. Violence following the 2007 Kenyan presidential election [JURIST report] left at least 1,000 people dead and 500,000 displaced after protests erupted from allegations that President Mwai Kibaki [official profile] committed voter fraud.
