- Lok Sabha (House of the People) and State Legislative Assemblies (Vidhan Sabha) are temporary houses and are dissolved periodically (normally every five years, or earlier). - Rajya Sabha (Council of States) is a permanent house and cannot be dissolved. One-third of its members retire every two years. It cannot be abolished. - State Legislative Councils (Vidhan Parishad) are also permanent bodies in the states that have them, meaning they cannot be dissolved. - However, unlike the Rajya Sabha, a State Legislative Council can be abolished or created by the Parliament through a simple majority, provided the concerned State Legislative Assembly passes a resolution to that effect by a special majority.
