SG: There is nothing above President. So, both provisions in same document, word withhold used in two places leads to one conclusion. Central passes a law, and some State passes a law that this law will not apply and Bill is presented, can he assent? no. can he refer? no. palpably wrong. Withhold in rarest of rare circumstances- his existence as constitutional functionaries and his oath to defend the Constitution requires him. Unless this is read, Governor office will become postman.
