Notwithstanding anything contained in any law for the time being in force,—
(a)no court shall impose a sentence under this Act for a contempt of court unless it is satisfied that the contempt is of such a nature that it substantially interferes, or tends substantially to interfere with the due course of justice;
(b)the court may permit, in any proceeding for contempt of court, justification by truth as a valid defence if it is satisfied that it is in public interest and the request for invoking the said defence is bona fide.]
