In June 2009, several African states, including Comoros, Djibouti, and Senegal, called on African states parties to withdraw "en masse" from the statute in protest against the indictment of Sudanese President Omar al-Bashir. In September 2013, Kenya's National Assembly passed a motion to withdraw from the ICC in protest against the ICC prosecution of Kenyan Deputy President William Ruto and President Uhuru Kenyatta (both charged before coming into office). A mass withdrawal from the ICC by African member states in response to the trial of Kenyan authorities was discussed at a special summit of the African Union in October. The summit concluded that serving heads of state should not be put on trial, and that the Kenyan cases should be deferred. However, the summit did not endorse the proposal for a mass withdrawal due to lack of support for the idea. In November the ICC's Assembly of State Parties responded by agreeing to consider proposed amendments to the Rome Statute to address the AU's concerns.
