Article 71(1) of the Constitution of India explicitly states that all doubts and disputes arising out of or in connection with the election of a President or Vice-President shall be inquired into and decided by the Supreme Court. The decision of the Supreme Court in such matters is final.
The Supreme Court of India is the sole constitutional authority empowered to inquire into and decide doubts and disputes regarding the election of the President and Vice President.
The Election Commission of India is responsible for conducting the elections to the offices of President and Vice President, but it does not have the power to resolve election disputes or challenges. Such matters must be filed as an election petition directly before the Supreme Court.
