Step 1: Key Concept:
The Rajya Sabha (Council of States) is the upper house of the Indian Parliament. Unlike the lower house (Lok Sabha), it is a continuing chamber and not subject to dissolution. This feature makes it a 'permanent house'.
Step 2: Detailed Explanation:
The Rajya Sabha is called the permanent house for the following reasons:
1. It is not subject to dissolution: While the Lok Sabha has a fixed term of five years and can be dissolved earlier, the Rajya Sabha is a permanent body and cannot be dissolved. This ensures continuity in the legislative process even when the Lok Sabha is dissolved or in the process of being constituted.
2. Staggered Terms of Members: The members of the Rajya Sabha are elected for a term of six years. However, all members do not complete their terms at the same time. One-third of its members retire at the expiration of every second year. This system ensures that the house is never empty and functions in a continuous cycle. New members are elected to replace those who have retired, thus maintaining the house's permanent character.
