SEBI v. Kishore R. Ajmera: preponderance of probabilities and inference from circumstance

How do you prove manipulation?

Market manipulation is, by its nature, covert. Those who create artificial volumes, ramp prices in illiquid scrips, or match trades to manufacture the appearance of genuine dealing do not leave signed confessions. They leave patterns — trades placed and reversed, volumes that appear from nowhere in a scrip that ordinarily barely trades, counterparties who recur. The enforcement problem the Supreme Court confronted in this appeal was how the securities regulator is to prove such conduct, and to what standard, when the actors have every incentive and ability to conceal their intent.

The case came to the Court on appeals concerning the liability of brokers in connection with trading in an illiquid scrip that had generated artificial volumes through matched transactions. SEBI had proceeded against the brokers; the Securities Appellate Tribunal had taken a view on their liability; and the contest reached the Supreme Court, where a two-judge bench of Justices Ranjan Gogoi and Prafulla C. Pant addressed two linked questions of principle: what standard of proof governs SEBI enforcement, and how far the regulator may rely on circumstantial evidence to establish a manipulative scheme.

A civil standard for a regulatory wrong

The Court's first holding settled a question that recurs in every contested SEBI matter. Enforcement under the SEBI Act and the regulations made under it is civil and regulatory in character, directed at protecting the integrity of the securities market, not at imposing the stigma and deprivation of liberty that the criminal law carries. The standard of proof is correspondingly the civil standard — the preponderance of probabilities. It is enough that, on the material before the regulator, the violation is shown to be more probable than not. SEBI need not establish its case beyond reasonable doubt.

That holding matters because respondents in SEBI proceedings frequently argue, in effect, that they must be treated as if accused of a crime — that any doubt must be resolved in their favour, that intent must be proved to the criminal hilt. The Court rejected that framing. Securities enforcement is protective regulation; its proof standard is the ordinary civil one; and a regulator that establishes the more-probable-than-not case has discharged its burden.

Inference from the totality of circumstances

The second holding addressed the proof of manipulative intent. Because direct evidence is so rarely available, the Court affirmed that SEBI may build its case on circumstantial evidence — provided the circumstances, taken together, compel the conclusion. The reasoning must be a genuine inferential process, not a guess: the regulator draws, from the whole body of attending facts and circumstances, an inference that is irresistible.

The formulation does two things at once. It frees SEBI from an impossible demand for direct proof of a state of mind, and it disciplines the regulator's reasoning by insisting that the inference be irresistible — that the circumstances, properly weighed, leave no reasonable explanation other than manipulation. A suspicious pattern that admits of an innocent reading will not do; the totality must point, logically and inescapably, to wrongdoing. This is the evidentiary backbone on which a great deal of subsequent SEBI enforcement rests.

Calibrating broker liability

Applying these principles to the brokers, the Court was careful not to convert the broker into an automatic guarantor of every client trade. Trading in the illiquid scrip had produced artificial volumes through matched trades, and the question was when the executing broker shares responsibility for that scheme. The Court's answer was calibrated: a broker may be held liable where the pattern of trades and the surrounding circumstances logically point to the broker's complicity in the manipulative design, but the mere execution of trades, without more, does not automatically fix the broker with liability.

The distinction is important for market intermediaries. A broker is in the business of executing orders, and many trades that later turn out to be parts of a manipulative scheme will, at the point of execution, look like ordinary business. Liability attaches where the circumstances — the broker's knowledge, the obviousness of the pattern, the repetition of matched trades between the same parties, the absence of any genuine commercial rationale — support the irresistible inference that the broker was a participant, not a passive conduit. Where they do not, execution alone is not enough. The Court thus mapped its preponderance-and-inference standard onto the specific position of the intermediary, neither absolving brokers wholesale nor making them insurers of their clients' conduct.

The duty of due diligence

The Court did not leave the broker with no obligation at all. While mere execution does not by itself fasten liability, a broker who closes his eyes to obvious signs that trades are not genuine cannot shelter behind the claim that he was only carrying out instructions. The decision recognises that intermediaries occupy a position of responsibility in the market and are expected to exercise a measure of diligence in relation to the trades they put through. Where the pattern of dealing is so plainly abnormal — illiquid scrip, repeated matched trades, the same counterparties, prices unrelated to any genuine market — that no reasonably diligent broker could have failed to notice it, the failure to notice, or the decision to look away, becomes itself part of the totality from which complicity may be inferred. The standard is therefore neither strict liability nor a free pass; it is liability calibrated to what the circumstances put the broker on notice of, judged by the irresistible-inference test.

This calibration has practical consequences for how SEBI frames its show-cause notices and how intermediaries defend them. The regulator must do more than point to the bare fact that a broker executed the trades; it must marshal the surrounding circumstances into a case from which the broker's participation, or culpable indifference, irresistibly follows. The broker, in turn, can meet the case by showing a genuine commercial explanation for the trades, the absence of any feature that should have aroused suspicion, or the discharge of whatever diligence the situation reasonably demanded. The contest is fact-intensive, which is exactly why the Court declined to lay down a mechanical rule and insisted instead on reasoning from the whole picture.

Why the case anchors SEBI's enforcement

Kishore R. Ajmera is cited in SEBI matters far more often than its facts would suggest, because it supplies the two propositions on which contested enforcement turns. It tells the regulator and the tribunals what must be proved — a case more probable than not — and how it may be proved — by an irresistible inference from the totality of circumstances. Together these answer the recurring objection that manipulation cannot be established without a confession or a direct document. The Court's reply is that manipulation is ordinarily proved as it is concealed: through patterns and circumstances, weighed to the civil standard.

The decision belongs to the line of judgments through which the Supreme Court has built the evidentiary law of securities regulation in India. Later cases on disclosure, insider trading and fraudulent trade practices apply its preponderance-and-inference template, treating the irresistible-inference test as the settled method for proving conduct that the wrongdoer has taken care to disguise. It is, in that sense, less a case about brokers than a case about how the securities market is policed at all.
