The Supreme Court of India is the highest court in India and has the power to change its own rulings. This is because the Constitution of India grants the Supreme Court the authority to review, modify, or reverse its own judgments. This power is granted to ensure the court is able to correct any errors it may have committed in previous cases. It also allows the court to make sure its judgments stay in line with contemporary societal needs and laws. The court can also use this power to clarify any ambiguities in its previous judgments. Therefore, the Supreme Court is allowed to change its own rulings to ensure justice is served properly.
