The Rajya Sabha members are elected by the method of proportional representation by means of the single transferable vote (STV), very similar to how the members of legislative councils in states are elected. Members keep retiring after their 6-year tenure and elections take place as and when there is a vacancy.
The legislative process begins with the introduction of a Bill in either House of Parliament, i.e. the Lok Sabha or the Rajya Sabha. A Bill can be introduced either by a Minister or by a private member. In the former case it is known as a Government Bill and in the latter case it is known as a Private Member's Bill.
