Any person being investigated or prosecuted may request the disqualification of a prosecutor from any case "in which their impartiality might reasonably be doubted on any ground".  Requests for the disqualification of prosecutors are decided by the Appeals Chamber.  A prosecutor may be removed from office by an absolute majority of the states parties if he or she "is found to have committed serious misconduct or a serious breach of his or her duties" or is unable to exercise his or her functions.  However, critics of the Court argue that there are "insufficient checks and balances on the authority of the ICC prosecutor and judges" and "insufficient protection against politicized prosecutions or other abuses".  Henry Kissinger says the checks and balances are so weak that the prosecutor "has virtually unlimited discretion in practice".  Some efforts have been made to hold Kissinger himself responsible for perceived injustices of American foreign policy during his tenure in government.
