Salve reads out from Rattan Lal (1964) -

"...Under Article 20 of the Constitution, no person shall be convicted of any offence except for violation of a law in force at the time of the commission of the act charged as an offence, nor be subjected to a penalty greater than that which might have been inflicted under the law in force at the time of the commission of the offence. But an ex post facto law which only mollifies the rigour of criminal law does not fall within the said prohibition."
