The Omani legislature is the bicameral Council of Oman, consisting of an upper chamber, the Council of State (Majlis ad-Dawlah) and a lower chamber, the Consultative Council (Majlis ash-Shoura). Political parties are banned. The upper chamber has 71 members, appointed by the Sultan from among prominent Omanis; it has only advisory powers. The 84 members of the Consultative Council are elected by popular vote to serve four-year terms, but the Sultan makes the final selections and can negotiate the election results. The members are appointed for three-year terms, which may be renewed once. The last elections were held on 27 October 2019, and the next is due in October 2023. Oman's national anthem, "As-Salam as-Sultani" is dedicated to former Sultan Qaboos.
