"In October 2006, King Abdullah issued a new succession law that amended the 1992 Basic Law and formalized the process by creating the Allegiance Commission. The new law both defines how a king will choose among possible candidates and provides a formal way for developing a consensus to choose the king's successor. The Allegiance Commission will select a king and crown prince upon the death or incapacitation of either. This commission expands the role of the ruling family in the selection process. ... It is composed of some 35 sons and grandsons of the late founder of the Kingdom, Abd al-Aziz al-Saud, who will vote in secret ballots on who could and could not be eligible to be future kings and crown princes."
