The President can be removed from office by a process of impeachment for ‘violation of the Constitution’. However, the Constitution does not define the meaning of the phrase ‘violation of the Constitution’. 

The impeachment charges can be initiated by either House of Parliament. These charges should be signed by one-fourth of members of the House (that framed the charges), and a 14 days’ notice should be given to the President. 

No President has so far been impeached.
