SEBI's Adani probe was thorough. The Supreme Court just said it.

The Supreme Court just rejected every demand to transfer the Adani investigation to the CBI. Here's why.

The courtroom fell still as Chief Justice Dr Dhananjaya Y Chandrachud read the operative order. On the bench lay a slim stack of SEBI status reports, their pages worn from handling. The verdict, delivered on January 3, 2024, sent a clear signal to India's capital markets: the court would not second-guess a regulator that had done its homework.

The case — Vishal Tiwari v. Union of India & Ors. — began with a bombshell. In January 2023, Hindenburg Research, a US-based short-seller, published a report alleging financial fraud by the Adani Group. The stock market reacted violently. Adani Group companies lost billions in market value within days. Petitioners rushed to the Supreme Court, demanding a full investigation into allegations of stock manipulation and related party transactions concealed through shell companies.

When the market crashed and the court stepped in

The Supreme Court did not sit idle. In March 2023, it constituted an Expert Committee headed by a former Supreme Court judge and directed the Securities and Exchange Board of India (SEBI — the market regulator) to continue its ongoing investigation into the Adani Group. The court wanted answers: had SEBI's regulatory framework failed? Were there gaps that allowed the alleged violations to occur?

SEBI got to work. By August 2023, the regulator had completed 22 out of 24 investigations. Its conclusion: no systemic market risk existed. The Expert Committee agreed. But the petitioners were not satisfied. They wanted the investigation transferred to the Central Bureau of Investigation (CBI) or a Special Investigation Team (SIT). They also wanted the court to revoke certain regulatory amendments that SEBI had made — amendments the petitioners argued had weakened oversight.

The legal question: can a court rewrite a regulator's rules?

The petitions were filed under Article 32 of the Constitution (the right to approach the Supreme Court directly for enforcement of fundamental rights). The petitioners challenged SEBI's investigation into alleged violations of Rule 19A of the Securities Contracts (Regulation) Rules, 1957 (the rule requiring minimum public shareholding in listed companies), the SEBI (Foreign Portfolio Investments) Regulations, 2014 (rules governing foreign investors), and the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015 (rules on related party transactions).

The core question was deceptively simple: could the court step in and take over an investigation from a statutory regulator just because the petitioners believed the regulator had not done enough?

The petitioners argued that SEBI's investigation was inadequate. They pointed to the Hindenburg report as evidence of wrongdoing. They claimed that SEBI's regulatory amendments had diluted protections against related party transactions — transactions between a company and its promoters or directors that could be used to siphon money out of the company.

The Union of India and SEBI pushed back. They argued that SEBI had conducted a thorough investigation. The regulator had examined 24 specific issues. It had found no evidence of stock manipulation or systemic market failure. The amendments to the regulations, they said, had actually tightened the framework, not loosened it.

Why the court refused to transfer the investigation

The Supreme Court examined the scope of judicial review over expert regulatory bodies. The bench — Chief Justice Chandrachud and Justice JB Pardiwala — held that courts cannot direct SEBI to revoke or amend its regulations unless those regulations are ultra vires the parent legislation (beyond the legal power granted by the SEBI Act) or the Constitution. The legality of a regulation, not its wisdom or soundness as policy, is the subject of judicial review.

On the specific allegations, the court found that the amendments to the Foreign Portfolio Investments Regulations and the Listing Obligations and Disclosure Requirements Regulations had tightened the regulatory framework rather than diluting it. Allegations of regulatory failure based on changes in regulations, the court said, are not a recognized ground for judicial intervention.

Then came the decisive point. The court held that transferring an investigation from a statutory regulator to the CBI or an SIT requires "glaring, willful and deliberate inaction" by the regulator. Without cogent material showing inadequacy or bias, the court will not supplant the authority vested with investigative power. The threshold was not met in this case.

The court also rejected the petitioners' reliance on the Hindenburg report. Third-party reports and newspaper articles, the bench observed, cannot be relied upon as conclusive proof of inadequacy of investigation by a statutory regulator. Their veracity and sources must be demonstrated to be unimpeachable.

The procedural journey: a timeline of key events

The case wound its way through the Supreme Court over nearly a year. On February 10, 2023, the writ petitions were first filed. The court noted the need for an expert committee and sought inputs from the Solicitor General. On March 2, 2023, an interim order constituted the Expert Committee and directed SEBI to continue its investigation. The Expert Committee submitted its report on May 6, 2023, finding no systemic market risk. SEBI was granted an extension until August 14, 2023, to complete its probe. On August 25, 2023, SEBI filed its status report confirming that 22 of 24 investigations were complete. Finally, on November 24, 2023, the court heard final arguments and reserved its verdict, which was delivered on January 3, 2024.

The provisions that framed the dispute

The court engaged with several key provisions. Article 32 of the Constitution served as the procedural vehicle for the petitioners to approach the Supreme Court directly. Article 142, which allows the court to pass orders necessary for complete justice, was invoked by the petitioners to seek transfer of the investigation. Rule 19A of the Securities Contracts (Regulation) Rules, 1957 — the minimum public shareholding requirement — was a primary target of the allegations. Section 11 of the SEBI Act, 1992, which defines SEBI's functions, and Section 30, which grants SEBI the power to make regulations, were interpreted by the court to determine the scope of the regulator's authority. The related party transaction definitions under Regulations 2(1)(zb) and 2(1)(zc) of the LODR Regulations, 2015, and Section 2(76) of the Companies Act, 2013, were examined. The FPI Regulations' provisions on opaque structures were left undisturbed by the court.

What the court actually ordered

The operative order was precise. All petitions were dismissed. No regulatory failure was found. No transfer of investigation was ordered. SEBI was directed to complete the remaining two investigations within three months. The regulator was asked to consider the Expert Committee's recommendations. The government and SEBI were also asked to consider measures to regulate short selling (the practice of betting on a stock's decline, which Hindenburg had done) and to inquire into infractions.

The court cited several precedents to support its reasoning, including IFB Agro Industries Ltd v. SICGIL India Ltd (2023), Prakash Gupta v. SEBI (2021), Himanshu Kumar v. State of Chhattisgarh (2022), and K.V. Rajendran v. Superintendent of Police CBCID South Zone, Chennai (2013) — all of which stand for the principle that courts should not lightly interfere with the functioning of expert regulatory bodies.

The ratio decidendi: the principles that governed the verdict

The court laid down four key principles. First, courts cannot direct SEBI to revoke or amend its regulations unless they are ultra vires the parent legislation or the Constitution; the legality, not the wisdom or soundness of policy, is the subject of judicial review. Second, amendments to FPI Regulations and LODR Regulations tightened the regulatory framework rather than diluting it; allegations of regulatory failure based on changes in regulations are not a recognized ground for judicial intervention. Third, transfer of investigation from a statutory regulator to CBI/SIT requires glaring, willful and deliberate inaction; absent cogent material showing inadequacy or bias, the court will not supplant the authority vested with investigative power. Fourth, third-party reports and newspaper articles cannot be relied upon as conclusive proof of inadequacy of investigation by a statutory regulator; their veracity and sources must be demonstrated to be unimpeachable.

Why this matters for every market participant

For advocates, CFOs, and founders reading this, the judgment offers a clear message: the Supreme Court trusts SEBI to do its job. The court will not entertain demands for a parallel investigation unless there is concrete evidence of regulatory failure — not just a report from a short-seller or a newspaper article. The judgment also affirms that regulatory amendments are matters of policy, not justiciability, as long as they stay within the bounds of the parent law.

THE PLAY: If you are challenging a SEBI investigation or regulation in court, you must show specific, cogent evidence of regulatory failure — a third-party report, no matter how explosive, will not suffice.

The court ended where it began: with a regulator that had done its work, and a court that refused to undo it. The silence in the courtroom when the verdict was read spoke louder than any argument could.
