Tamil Nadu elects 18 members to the Rajya Sabha. The number of members to be elected from each State has been fixed by the fourth schedule of the Constitution. Members of the Rajya Sabha are elected
for a term of six years and then they can be re-elected. The Rajya Sabha is known as Permanent House of the Parliament that never gets fully dissolved. Some of the important privileges and immunities are given to the Members of Rajya Sabha as follows.
