Court held that Explanations added to sections 132(1), 132(1A) and 132A(1) have been given retrospective effect for purpose given in objects and reasons for such amendment. Explanations to sections 132(1), 132(1A) and 132A(1) by Finance Act of 2017 preventing disclosure of reason to believe and reason to suspect in proceedings upto Tribunal cannot be said to be offending article 14, 19 or 21 of Constitution of India and retrospectivity of amendment is permissible unless it remains otherwise unconstitutional. Accordingly the  challenge to addition of Explanations to sections 132(1), 132(1A) and 132A(1) by Finance Act of 2017 was  rejected and they were held to be constitutionally valid.
