The Sharia court system constitutes the basic judiciary of Saudi Arabia and its judges and lawyers form part of the ulema, the country's religious leadership. There are also extra-Sharia government tribunals which handle disputes relating to specific royal decrees and since 2008, specialist courts, including the Board of Grievances and the Specialized Criminal Court. Final appeal from both Sharia courts and government tribunals is to the King and as of 2007[ [update]], all courts and tribunals followed Sharia rules of evidence and procedure.
