Government of Saudi Arabia
The central institution of Saudi Arabian Government is the monarchy. The Basic Law adopted in 1992 declared that Saudi Arabia is a monarchy ruled by the sons and grandsons of King Abd Al Aziz Al Saud, and that the Holy Qur'an is the constitution of the country, which is governed on the basis of Islamic law (Shari'a). There are no political parties or national elections. The king's powers are limited because he must observe the Shari'a and other Saudi traditions. He also must retain a consensus of the Saudi royal family, religious leaders (ulema), and other important elements in Saudi society. The leading members of the royal family choose the king from among themselves with the subsequent approval of the ulema.

Saudi kings gradually have developed a central government. Since 1953, the Council of Ministers, appointed by and responsible to the king, has advised on the formulation of general policy and directed the activities of the growing bureaucracy. This council consists of a prime minister, the first and second deputy prime ministers, 20 ministers (of whom the minister of defense also is the second deputy prime minister), two ministers of state, and a small number of advisers and heads of major autonomous organizations.

Legislation is by resolution of the Council of Ministers, ratified by royal decree, and must be compatible with the Shari'a. Justice is administered according to the Shari'a by a system of religious courts whose judges are appointed by the king on the recommendation of the Supreme Judicial Council, composed of 12 senior jurists. The independence of the judiciary is protected by law. The king acts as the highest court of appeal and has the power to pardon. Access to high officials (usually at a majlis, or public audience) and the right to petition them directly are well-established traditions.

The kingdom is divided into 13 provinces governed by princes or close relatives of the royal family. All governors are appointed by the King.

In March 1992, King Fahd issued several decrees outlining the basic statutes of government and codifying for the first time procedures concerning the royal succession. The King's political reform program also provided for the establishment of a national Consultative Council, with appointed members having advisory powers to review and give advice on issues of public interest. It also outlined a framework for councils at the provincial or emirate level.

In September 1993, King Fahd issued additional reform decrees, appointing the members of the national Consultative Council and spelling out procedures for the new council's operations. He announced reforms regarding the Council of Ministers, including term limitations of 4 years and regulations to prohibit conflict of interest for ministers and other high-level officials. The members of 13 provincial councils and the councils' operating regulations also were announced in September 1993. In October 2003, the Government announced that elections for half of the members of municipal councils will be held in 2004.

In July 1997, the membership of the Consultative Council was expanded from 60 to 90 members, and again in May 2001 from 90 to 120 members. Membership has changed significantly during expansions of the council as many members have not been reappointed. The role of the council is gradually expanding as it gains experience.
