Retrospective amendments cannot nullify a binding mandamus, but a no-interest security deposit clause was upheld under Article 14.

The earlier observation on non-payment of interest in security deposits was obiter, not the ratio, because it was made without direct adjudication on a no-interest clause. Retrospective validating amendments could remove the basis of a judicial decision, but they could not directly nullify a binding mandamus or final judgment by mere declaration; on that ground, the retrospective operation was invalid. However, a statutory condition denying interest on security deposits in a regulated money-lending or pawn-broking business was not per se arbitrary and did not violate Article 14, as the licence holder accepts the statutory terms of the regulated activity.

Issues: (i) Whether the earlier High Court ruling on interest in security deposits was binding ratio or only obiter; (ii) Whether the 1998 retrospective amendments could validly nullify the earlier mandamus and the basis of the prior judgment; (iii) Whether a statutory provision denying interest on security deposits is arbitrary and violative of Article 14 of the Constitution of India.

Issue (i): Whether the earlier High Court ruling on interest in security deposits was binding ratio or only obiter.

Analysis: The earlier decision had principally upheld the validity of the security-deposit requirement itself. The observation that a provision prohibiting interest would be unconstitutional was made in a setting where no such prohibitory provision then existed. The observation was therefore hypothetical, not necessary for the decision, and no independent adjudication had been made on a direct challenge to a no-interest clause.

Conclusion: The observation on non-payment of interest was obiter and not the ratio decidendi.

Issue (ii): Whether the 1998 retrospective amendments could validly nullify the earlier mandamus and the basis of the prior judgment.

Analysis: A legislature may enact validating laws and retrospectively amend a statute to remove the basis of a judicial decision, but it cannot directly overrule a final judgment inter partes or neutralise a mandamus by a mere declaration. Retrospective legislation that simply sets aside the effect of a binding judicial command, without removing the underlying defect, offends the separation of powers. On the facts, the amendments introduced a new no-interest condition and attempted to operate retrospectively without curing any demonstrated defect in the earlier law.

Conclusion: The retrospective operation of the validating amendments was illegal and invalid.

Issue (iii): Whether a statutory provision denying interest on security deposits is arbitrary and violative of Article 14 of the Constitution of India.

Analysis: Interest is compensation for the use or retention of money, but the entitlement to interest is not absolute. The business of money lending and pawn broking is a regulated and potentially usurious activity, and the legislature may impose onerous conditions to control it. A person seeking such a licence knowingly accepts the statutory condition attached to the business. In light of the nature of the business and the absence of any inherent constitutional right to interest on such deposits, the no-interest clause could not be treated as manifestly arbitrary.

Conclusion: The no-interest provision was not arbitrary and did not violate Article 14.

Final Conclusion: The challenge succeeded only to the extent that retrospective nullification of the earlier judgment was impermissible, while the substantive no-interest condition itself was upheld as constitutionally valid.

Ratio Decidendi: The legislature may retrospectively amend a law to remove the basis of a judicial decision, but it cannot by retrospective enactment directly nullify a binding mandamus or declare a final judgment ineffective; a no-interest condition on security deposits in a regulated business is not per se arbitrary under Article 14.
