Each state has a unicameral legislature called "Dewan Undangan Negeri" ("DUN", State Assembly). Members of DUN are elected from single-member constituencies drawn based on population. The state leader of the majority party in DUN is usually appointed Chief Minister by the Ruler or Governor. The term of DUN members is five years unless the assembly is dissolved earlier by the Ruler or Governor on the advice of the Chief Minister. Usually, DUN of the states in Peninsular Malaysia are dissolved in conjunction with the dissolution of the federal parliament, to have state elections running concurrently with the parliamentary election. However, Rulers and Governors hold discretionary powers in withholding consent to dissolve the DUN. Each state sends two senators elected by the DUN to the "Dewan Negara" (Senate), the upper house of the federal parliament.
