The power to increase the number of judges in the Supreme Court of India is vested in the Parliament. This is because the Constitution of India provides for the establishment of the Supreme Court and its jurisdiction, composition, and powers. Article 124 of the Constitution deals with the appointment of judges to the Supreme Court, while Article 146 provides for the appointment of ad-hoc judges to the Supreme Court if there is a shortage of regular judges. However, the number of judges in the Supreme Court can be increased only by the Parliament of India, which has the power to amend the Constitution under Article 368. Therefore, any proposal to increase the number of judges in the Supreme Court must be initiated by the Parliament through a constitutional amendment. The President of India has no role in this process, but must give assent to the constitutional amendment bill passed by the Parliament. The Chief Justice of India and the Law Commission also do not have the power to increase the number of judges in the Supreme Court.
