RS Nayak Vs AR Antulay, AIR 1984 SC 684,

Hon'ble Supreme Court of India observed as under, "...If the words of the Statute are clear and unambiguous, it is the plainest duty of the Court to give effect to the natural meaning of the words used in the provision. The question of construction arises only in the event of an ambiguity or the plain meaning of the words used in the Statute would be self defeating.”
