The Eleventh Amendment of the Constitution of India, officially known as The Constitution (Eleventh Amendment) Act, 1961, provided that the Vice-President shall be elected by the members of an electoral college consisting of the members of both Houses of Parliament, thereby dispensing with the earlier requirement of a joint meeting of members of both Houses of Parliament assembled for the said purpose. The 11th Amendment inserted a new clause (4) in article 71 of the Constitution to clarify that the election of President or Vice-President cannot be challenged on the ground of the existence of any vacancy for whatever reason in the appropriate electoral college.
