Explanation:

The power to increase the number of judges in the Supreme Court of India is vested in Parliament.
Even removal of a judge of the Supreme Court from his Office can be done by an order of the president. The President can issue the removal order only after an address by Parliament has been presented to him in the same session for such removal.
The address must be supported by a special majority of each House of Parliament (ie, a majority of the total membership of that House and a majority of not less than two-thirds of the members of that House present and voting).
