Article 143 of the Indian Constitution empowers the Supreme Court with advisory jurisdiction. This allows the President to seek an opinion of the Supreme Court on any issue of law or matter of public importance on which he deems it urgent to take such an opinion. On such mention from the President, the Supreme Court, after giving the issue such hearing as it deems fit, may report to the President its opinion thereon. The opinion is not compulsory but only advisory, and the President is free to follow or not to follow. However, the opinion extended under advisory jurisdiction carries great weight.
