The Bihar Legislature (IAST: Bihar Vidhan Mandal) is the supreme legislative body of the state of Bihar. It is a bicameral legislature composed of the Governor of Bihar and two houses: the Bihar Vidhan Parishad (Bihar Legislative Council) and the Bihar Vidhan Sabha (Bihar Legislative Assembly). The governor in his role as head of the legislature has full powers to summon and prorogue either house of legislature or to dissolve the Vidhan Sabha. The governor can exercise these powers only upon the advice of the Chief minister and his ministry. *
