- The Union Legislature consists of the Lok Sabha and the Rajya Sabha. Neither of these houses can be abolished. The Lok Sabha has a fixed term (usually 5 years) but is not abolished, it is dissolved and re- elected. The Rajya Sabha is a permanent house. - The State Legislature in some states is bicameral, consisting of the Vidhan Sabha (Legislative Assembly) and the Vidhan Parishad (Legislative Council). In other states, it is unicameral, having only a Vidhan Sabha. - The Vidhan Sabha is the primary elected house representing the people of the state and is a necessary part of the state legislature in all states (except UTs). It cannot be abolished. - The creation or abolition of a Vidhan Parishad in a state is provided for under Article 169 of the Constitution. Parliament can create or abolish a Vidhan Parishad by law if the Legislative Assembly of the state passes a resolution to that effect by a special majority.
