The power to increase the number of judges in the Supreme Court of India is vested in

1. The question asks which authority is vested with the power to increase the number of judges in the Supreme Court of India. 2. Article 124(1) of the Constitution of India provides that the Supreme Court of India shall consist of a Chief Justice of India and, until Parliament by law prescribes a larger number, of not more than seven other judges. 3. This provision explicitly grants the power to the Parliament to increase the number of judges through legislation. 4. The Parliament has exercised this power multiple times since the Constitution came into force, increasing the strength of the Supreme Court periodically through Acts of Parliament. 5. The President of India appoints the judges but does not determine the strength of the court. 6. The Chief Justice of India is the head of the judiciary but does not have the legislative power to change the court's strength. 7. The Law Commission is an advisory body and has no such legislative or constitutional power. Therefore, the power is vested in the Parliament.
