Article 57 of the Constitution of India explicitly deals with the eligibility for re-election of the President. It states that a person who holds or has held office as President shall be eligible for re-election to that office, subject to other provisions of the Constitution. Therefore, the Constitution allows re-election of a person to the President’s post.
– Article 57: “Eligibility for re-election.โ€”A person who holds, or who has held, office as President shall, subject to the other provisions of this Constitution, be eligible for re-election to that office.”
– There is no constitutional limit on the number of terms a person can serve as President in India, unlike, for example, the USA (where it is limited to two terms).
While the Constitution permits multiple terms, no person has served more than two terms as President of India so far (Dr. Rajendra Prasad served two terms). The practice has been for Presidents to serve one term, though re-election is constitutionally permissible.
