Vice-President performs a dual role : (1) as Vice-President (2) as the Chairman of Rajya Sabha. The Vice-President is the ex-officio Chairman of Rajya Sabha which means that whosoever is the Vice-President, he/she presides over the Rajya Sabha and performs normal duties of a presiding officer. These include maintenance of order in the House, allowing members to speak and ask questions, and putting bills and motions to vote.
He/She is elected by an electoral college which consists of the members of both Houses of the Parliament. He/She is
elected according to the system of proportional representation by means of a single transferrable vote, and the voting is by secret ballot.
The Vice-President can be removed from his office by a resolution of the Rajya Sabha passed by its members and agreed by Lok Sabha. At least fourteen days’ notice is necessary before such resolution is moved.

These include maintenance of order in the House, allowing members to speak and ask questions, and putting bills and motions to vote. Since the Vice-President is not a member of the Rajya Sabha, he/she cannot vote in the House. But, in case of a tie (equality of votes in favour and against a bill), the Vice President exercises his/her casting vote so that a decision can be reached.
If ever a vacancy arises in the office of President, due to death, resignation or impeachment, the Vice-President officiates as the President for not more than six months (see above). During that period, he enjoys all powers of the President, and does not preside over the House when he officiates as President.
In case the President is temporarily unable to discharge his/her functions, the Vice-President may be called upon to discharge his/her functions, without becoming officiating President.
