The Supreme Court of India, through a five-judge Constitution Bench, on 11 September 2023 held that the 2014 declaration of unconstitutionality of Section 6A of the Delhi Special Police Establishment Act, 1946 operates retrospectively from the date of the provision's insertion. The Bench, led by Chief Justice D.Y. Chandrachud, ruled that a law declared violative of Part III of the Constitution is void ab initio and unenforceable from its very inception.
Background
The matter arose from a CBI investigation registered in December 2004 against Dr. R.R. Kishore under the Prevention of Corruption Act, 1988, for allegedly accepting a bribe. The respondent sought discharge on the ground that the CBI had initiated the investigation without obtaining prior approval of the Central Government as required under Section 6A of the DSPE Act. Section 6A, inserted on 11 September 2003, mandated that the CBI obtain prior government sanction before investigating officers of the rank of Joint Secretary and above.
In 2014, the Supreme Court in Subramanian Swamy v. Central Bureau of Investigation struck down Section 6A as unconstitutional for violating Article 14 of the Constitution, holding that it created an unreasonable classification shielding senior bureaucrats from investigation. However, the question of whether this declaration had retrospective or only prospective effect remained unresolved, leading to conflicting High Court decisions.
Key Holdings
The Constitution Bench laid down the following principles:
Retrospective invalidity: The declaration of unconstitutionality in Subramanian Swamy applies from the date of insertion of Section 6A, namely 11 September 2003. The provision is treated as having never existed in law.
Void ab initio doctrine: When a statute is declared unconstitutional for violating fundamental rights under Part III of the Constitution, it is void from the moment of its enactment. It is non est in the eyes of law and possesses no legal validity or binding authority at any point.
Procedural nature of Section 6A: The Court clarified that Section 6A was a procedural safeguard for senior government servants and did not constitute any substantive right, create any new offence, or prescribe any sentence. Its removal does not prejudice any accused person.
CBI investigations validated: All CBI investigations conducted without prior governmental approval during the period Section 6A was in force (2003-2014) are valid and cannot be challenged on the ground of non-compliance with the struck-down provision.
Ongoing cases unaffected: Pending prosecutions where discharge was sought on the basis of non-compliance with Section 6A cannot succeed, as the provision is deemed to have never existed.
Implications for Practitioners
This judgment settles a significant procedural uncertainty that had stalled multiple corruption prosecutions across the country. Defence counsel who had obtained stays or discharge orders based on CBI's failure to seek prior government approval under Section 6A will find those arguments foreclosed. Pending appeals and revision petitions challenging CBI investigations on this ground are effectively rendered infructuous.
For investigating agencies, the ruling removes any residual ambiguity about the validity of investigations initiated between September 2003 and the 2014 Subramanian Swamy decision. Prosecutors can now proceed with trials without the preliminary objection of investigative irregularity.
The broader constitutional significance lies in the Court's unequivocal endorsement of the void ab initio doctrine for fundamental rights violations. This reaffirms that a law violating Part III never acquires legal validity, regardless of the duration it remains on the statute book before judicial challenge. Future litigants challenging statutes under Part III can rely on this pronouncement to argue retrospective relief.
