Directorate Of Revenue Intelligence Vs Raj Kumar Arora & Ors (Supreme Court of India)
Supreme Court Clarifies Retrospective Application of Overruling Judgments in NDPS Case
New Delhi: The Supreme Court of India has reiterated the established legal principle that when a judicial precedent is overruled, the subsequent judgment operates retrospectively, impacting past transactions unless explicitly stated otherwise by the court. This significant pronouncement came in the case of Directorate Of Revenue Intelligence Vs Raj Kumar Arora & Ors, clarifying the interplay between the Narcotic Drugs and Psychotropic Substances Act, 1985 (NDPS Act) and the Drugs and Cosmetics Act, 1940 (D&C Act), particularly concerning substances listed in the Schedule to the NDPS Act but not in Schedule I of the NDPS Rules.
The apex court emphasized that a judicial decision does not create new law but rather clarifies the existing legal position. Consequently, an overruling judgment retroactively unveils the “correct principle of law,” which is then applied to past events. The general rule is that such overrulings have retrospective effect, with exceptions only for matters that have attained the status of res judicata (already decided) or for accounts that have been settled. The court referred to its earlier decision in Assistant Commissioner, Income Tax, Rajkot v. Saurashtra Kutch Stock Exchange Limited (2008) to underscore this point.
Furthermore, the court stated that any intention to apply a judgment prospectively, or to invoke the doctrine of “prospective overruling,” must be explicitly and clearly articulated. Prospective overruling, being an exception to the standard retrospective application of judgments and the doctrine of precedent, is rooted in the understanding that “the past cannot always be erased by a new judicial declaration.” The decision to apply a law declared by the court prospectively stems from the court’s discretion, where it assesses the merits and demerits of both retrospective and prospective application, applying the latter only when deemed appropriate and necessary. The absence of an express declaration of prospectivity implies that the default rule of retrospectivity will prevail.

In the context of the NDPS Act and its rules, alongside the D&C Act and its rules, the Supreme Court laid down the following key principles:
