Insider trading is, by its nature, a covert offence: there is rarely a confession and almost never a written record saying "I traded because I knew." The entire enforcement architecture of the SEBI (Prohibition of Insider Trading) Regulations, 2015 therefore turns on one question — how does the regulator investigate and prove what an insider knew and did? Unlike the repealed 1992 Regulations, the 2015 Regulations contain no self-contained "Board's right to investigate" chapter; instead they lean on the muscular investigative machinery of the parent statute, principally Section 11C of the SEBI Act, 1992, supplemented by the informant mechanism in Chapter IIIA and a body of case law that fixes the standard of proof. This chapter maps that machinery end-to-end — the trigger, the powers of summons and search, the evidentiary calculus of circumstantial proof, the noticee's right to the investigation report, and the leading judgments that police the regulator's reach.
Where the power to investigate comes from
A common examination misconception is that the PIT Regulations themselves house a dedicated investigation chapter. They do not. The 1992 Regulations contained Regulations 5 to 8 conferring a "Board's right to investigate," notice requirements and obligations of the person investigated. When the 2015 Regulations replaced them, those provisions were dropped because the investigative power had by then been consolidated in the parent enactment. The operative source today is Section 11C of the SEBI Act, 1992 — inserted by the SEBI (Amendment) Act, 2002 with effect from 29 October 2002 — read with SEBI's general powers under Sections 11 and 11B.
Section 11C(1) permits the Board, where it has "reasonable grounds to believe" that the transactions in securities are being dealt with in a manner detrimental to investors or the securities market, or that any intermediary or person associated with the securities market has violated the Act, rules or regulations, to direct an investigating authority to investigate the affairs of such persons and to report. The threshold is deliberately low and forward-looking: SEBI need not name a culprit at the outset. It investigates a transaction and identifies wrongdoers as the trail develops. The PIT-specific flavour is added by the substantive prohibitions in Regulation 4 (trading while in possession of UPSI) and Regulation 3 (communication or procurement of UPSI), violations of which are the typical object of an 11C investigation.
The trigger: reasonable grounds and the inquisitorial character
An investigation does not begin in a courtroom posture. The Securities Appellate Tribunal and the courts have repeatedly characterised SEBI's role at the investigation stage as inquisitorial rather than adjudicatory. In DLF Ltd. v. SEBI, the Tribunal underscored that during investigation SEBI functions in an inquisitorial capacity — gathering material, forming a preliminary view — distinct from the quasi-judicial role it assumes when it later adjudicates through a show-cause notice and a reasoned order. This distinction matters because the procedural protections owed at the investigation stage are lighter than those owed at adjudication.
The "reasonable grounds to believe" formula in Section 11C(1) is not a mere formality. Tribunals have read it to require articulable facts rather than bald suspicion; an investigation order grounded only in conjecture is vulnerable. In practice the trigger arrives through several channels: surveillance alerts thrown up by exchange systems, referrals from a stock exchange, complaints, suo motu market-rumour analysis, and — since 2019 — the formal informant mechanism. SEBI's first analytical step is almost always to fix the UPSI period: the window between the information coming into existence and its becoming generally available, against which all suspicious trades are then mapped.
Preliminary examination versus formal investigation
Operationally, SEBI's enforcement work proceeds in graded stages. A preliminary examination (sometimes called a preliminary inquiry) is a low-intrusion review of trading data, call-data patterns, KYC links and timing, conducted before a formal investigation is ordered. Only where this preliminary scrutiny throws up sufficient material does SEBI pass a formal order under Section 11C appointing an investigating authority. The graded structure is now visible on the face of the PIT Regulations themselves: the definition of "original information" in Chapter IIIA contemplates information that may "commence an examination or inquiry or audit" or "assist in an ongoing examination or investigation or inquiry or audit" — expressly distinguishing examination, inquiry, investigation and audit as separate enforcement modes.
The practical significance for an aspirant is that the noticee's rights crystallise at different points. At preliminary examination there is no entitlement to be heard; the duty to disclose material and to give a hearing attaches once SEBI moves to a show-cause notice founded on the investigation. This staged approach also explains why SEBI can quietly assemble a substantial documentary record — brokerage trails, demat statements, bank records, mobile-tower data — long before the person under scrutiny realises an investigation is afoot.
Powers of the investigating authority: summons, production and examination on oath
Once a formal investigation is ordered, Section 11C arms the investigating authority with coercive powers that mirror those of a civil court. Section 11C(2) obliges every manager, managing director, officer and other person of the company or intermediary, and every other associated person, to produce books, registers, documents and records and to furnish information to the investigating authority. Section 11C(3) empowers the authority to examine on oath any such person and require him to answer questions or make statements; Section 11C(5) requires those statements to be recorded.
Refusal carries teeth. Section 11C(6) provides that a person who, without reasonable cause, fails to produce documents, furnish information or appear for examination commits an offence punishable with imprisonment up to one year, or fine up to one crore rupees, or both, with a further fine of up to five lakh rupees for each day of continuing default. Crucially, Section 11C(7) makes the examination notes — reduced to writing and signed by the person examined — usable as evidence against him. The self-incrimination challenge to this scheme was rejected in Multibagger Securities Research & Advisory (P) Ltd. v. SEBI, the tribunal holding that a regulatory examination compelling answers does not offend the constitutional protection in the way a criminal interrogation might.
Search and seizure: Section 11C(8)–(9)
The most intrusive power is the authority to search and seize. Under Section 11C(8), where the investigating authority has reasonable ground to believe that books, registers, documents or records are likely to be destroyed, mutilated, altered, falsified or secreted, the authority may make an application to the designated court (a Magistrate or Judge of a designated court in Mumbai) for an order authorising search of premises and seizure of such material. Section 11C(9) applies the provisions of the Code of Criminal Procedure relating to searches and seizures, so far as may be, to searches under this section.
The procedural detail is fleshed out by the SEBI (Procedure for Search and Seizure) Regulations, 2014, which prescribe the form of the application to the Chairman, the contents of the search warrant, and the safeguards attending execution. Because search and seizure is the sharpest tool in SEBI's kit, the requirement of prior judicial authorisation operates as the principal check against abuse — the regulator cannot conduct a dawn raid on its own ipse dixit. For PIT investigations, seized material commonly includes diaries, deal notes, electronic devices and communications evidencing the flow of UPSI between a connected person and a tippee.
The digital trail and the structured digital database
Modern PIT investigations are overwhelmingly data-driven, and the 2015 Regulations have been amended to manufacture an evidentiary trail that investigators can later mine. Regulation 3(5) requires the board of directors (or heads of organisation) of every person handling UPSI to maintain a structured digital database containing the nature of the UPSI and the names and PAN of persons who shared it and with whom it was shared, maintained internally with time-stamping and audit trails to prevent tampering. Regulation 3(6) requires that this database be preserved for at least eight years, and — critically for enforcement — "in the event of receipt of any information from the Board regarding any investigation or enforcement proceedings," the relevant information must be preserved until the completion of those proceedings.
This is a deliberate evidentiary design: it converts the contemporaneous handling of UPSI into a documented, immutable record that an investigator can demand under Section 11C(2). Coupled with exchange-level surveillance, call-data records and KYC linkages, the structured database materially eases the regulator's perennial difficulty — proving the otherwise invisible act of communication of UPSI.
The informant mechanism: Chapter IIIA
In December 2019 SEBI inserted Chapter IIIA into the PIT Regulations, creating India's first reward-backed whistle-blower regime targeted specifically at insider trading. Regulation 7A defines an "Informant" as an individual who voluntarily submits a Voluntary Information Disclosure Form to the Board relating to an alleged violation of "insider trading laws" — defined to include Section 15G of the Act and Regulations 3, 4, 9 and 9A in so far as they pertain to trading or communication of UPSI.
The chapter erects an institutional scaffolding: an Office of Informant Protection, an Informant Incentive Committee, and a reward of up to ten percent of monies disgorged (subject to a cap) where "original information" leads to disgorgement of at least one crore rupees in monetary sanctions. "Original information" must be derived from the informant's independent knowledge, not already known to the Board, and "sufficiently specific, credible and timely" to commence or assist an examination, inquiry, investigation or audit. The chapter also discourages abuse — "irrelevant, vexatious and frivolous information" is excluded, and informants enjoy confidentiality and anti-retaliation protection. The mechanism is significant because it attacks insider trading's core evidentiary problem at the source: it incentivises the people closest to the UPSI to come forward.
The standard of proof: preponderance and circumstantial evidence
Because direct proof of insider trading is almost never available, the evidentiary standard SEBI must meet is the analytical heart of the subject. The settled position, affirmed by the Supreme Court in SEBI v. Kishore R. Ajmera, (2016) 6 SCC 368, is that proceedings before SEBI are civil in character and the standard of proof is the preponderance of probabilities, not proof beyond reasonable doubt. The Court held that SEBI may rely on circumstantial evidence and on "a logical process of reasoning from the totality of the attending facts and circumstances" so that an "irresistible inference" can be drawn — for instance from the pattern and timing of trades, order volumes and the interval between orders.
The Tribunal had earlier blessed this approach in V.K. Kaul v. Adjudicating Officer, SEBI (2012), where it upheld a finding of insider trading built on circumstantial evidence — the proximity of a connected person to the source of UPSI and trades placed by his wife immediately before a price-moving transaction. Yet the inference must be "irresistible"; mere suspicion or probabilising will not do. This is the doctrinal tension that recurs through every PIT investigation: SEBI is permitted to infer, but not to assume.
Balram Garg and the limits of circumstantial inference
The high-water mark for the noticee's protection is Balram Garg v. SEBI, 2022 INSC 441 (decided April 2022). The Supreme Court set aside SEBI's findings against the Managing Director of PC Jeweller and his relatives, holding that the regulator had impermissibly assumed the communication of UPSI from mere closeness of relationship. The Court emphasised that to sustain a charge of communication under Regulation 3, there must be material showing actual communication — "there has to be a tangible material" of interaction — and that the foundational facts establishing such communication must be proved, not presumed from proximity alone.
The case also clarified the "connected person" and "immediate relative" analysis: persons outside the statutory definition of immediate relative cannot be roped in merely because they are family. Balram Garg is read as raising SEBI's evidentiary burden, and it must be reconciled with Ajmera: the regulator may still draw inferences from circumstances, but where the inference rests on communication, it cannot be drawn from relationship plus opportunity alone. The earlier decision in Chintalapati Srinivasa Raju v. SEBI, (2018) 7 SCC 443 — arising from the Satyam scam — had similarly insisted that to treat a person as a deemed insider there must be material showing he could "reasonably be expected" to have access to UPSI, not a mechanical inference from a directorship.
Who can be investigated, and the corporate-interest defence
The universe of persons exposed to a PIT investigation is fixed by the definitions of "insider," "connected person" and "UPSI" examined in the definitions chapter. The reach is wide: a connected person is anyone associated with the company in a contractual, fiduciary or employment relationship that allows reasonable access to UPSI, and the 2015 Regulations added a "deemed connected person" category (immediate relatives, bankers, officials of intermediaries and the like).
An early and influential limitation on liability is the corporate-interest defence recognised in Rakesh Agarwal v. SEBI (2004), decided by the SAT under the 1992 Regulations. Agarwal, Managing Director of ABS Industries, had facilitated acquisition by Bayer of shares while in possession of UPSI about the impending deal; the Tribunal accepted that he had acted in the genuine interest of the company to ensure the foreign partner secured the requisite stake, and reversed the monetary direction. The principle survives in attenuated form: the 2015 Regulations now codify "legitimate purposes" defences and the proviso to Regulation 4 listing innocence-establishing circumstances, but the broad equitable notion that a bona fide corporate-benefit motive may negate the mischief traces to Rakesh Agarwal. The historical contrast is Hindustan Lever Ltd. v. SEBI (1998), where the Appellate Authority held HLL to be an insider in the BBLIL merger because common directorships and a common parent meant it could be presumed privy to the merger decision — an early illustration of how connection plus access founds insider status.
From investigation report to show-cause notice: natural justice
An investigation culminates in an investigation report submitted by the investigating authority to the Board. On the basis of its findings, SEBI either closes the matter or issues a show-cause notice initiating quasi-judicial proceedings before a Whole-Time Member or an Adjudicating Officer. The pivotal natural-justice question is how much of the investigation material the noticee is entitled to see.
The Supreme Court answered this decisively in T. Takano v. SEBI (2022), holding that SEBI is obliged to disclose the investigation report to a person served with a show-cause notice, because the report is "an intrinsic component of the Board's satisfaction" on whether a violation occurred. The Court rejected the regulator's stock defence that material it did not "rely upon" need not be disclosed — a mere ipse dixit of non-reliance is no longer a valid excuse, since relevance, not reliance, governs disclosure. This builds on the earlier disclosure jurisprudence in SEBI v. Price Waterhouse arising from Satyam, where the Court directed disclosure of statements recorded during investigation. The combined effect is that fair-hearing rights, dormant during the inquisitorial investigation stage, become robust the moment SEBI crosses into adjudication.
Outcomes: directions, penalties, settlement and prosecution
Where an investigation establishes a violation on the preponderance standard, SEBI's enforcement toolkit is broad. Under Sections 11, 11B and 11D it may pass directions — disgorgement of ill-gotten gains, debarment from the securities market, and restraint orders. Under Section 15G read with the adjudication machinery in Section 15-I, an Adjudicating Officer may impose monetary penalty for insider trading (the statutory ceiling having been progressively raised). Section 24 provides for criminal prosecution, and Section 26 governs cognizance of offences.
Two off-ramps deserve mention. First, the settlement mechanism under the SEBI (Settlement Proceedings) Regulations, 2018 allows a noticee to settle on a "without admission or denial" basis — the same regime whose High Powered Advisory Committee doubles as the Informant Incentive Committee under Chapter IIIA. Second, appeals from SEBI's orders lie to the Securities Appellate Tribunal and thence, on a question of law, to the Supreme Court under Section 15Z — the route through which Ajmera, Chintalapati and Balram Garg reached the apex court. For the broader regulatory backdrop, see the evolution of the PIT framework from the 1992 Regulations and the role of initial and continual disclosures in generating the data that surveillance ultimately mines.
Exam takeaways and analytical hooks
For judiciary and CLAT-PG purposes, four propositions are load-bearing. First, the investigative power is statutory (Section 11C of the SEBI Act), not regulatory — the 2015 Regulations dropped the 1992 investigation chapter. Second, the standard of proof is preponderance of probabilities and circumstantial evidence is admissible (Ajmera), but the inference must be irresistible and, where it concerns communication of UPSI, must rest on tangible material rather than relationship alone (Balram Garg). Third, SEBI is inquisitorial during investigation and quasi-judicial during adjudication, and the noticee's right to the investigation report attaches at the latter stage (T. Takano). Fourth, structural reforms — the structured digital database (Regulation 3(5)–(6)) and the informant mechanism (Chapter IIIA) — are deliberate evidentiary devices designed to overcome insider trading's chronic proof problem. A strong answer will trace the arc from trigger to show-cause notice and weave these authorities into a single narrative about how the regulator both wields and is restrained in its investigative power.
Frequently asked questions
Do the PIT Regulations, 2015 contain SEBI's power to investigate insider trading?
No. Unlike the repealed 1992 Regulations (which had a dedicated investigation chapter in Regulations 5 to 8), the 2015 Regulations rely on the parent statute. The principal source of investigative power is Section 11C of the SEBI Act, 1992, read with Sections 11 and 11B. The 2015 Regulations add the informant mechanism in Chapter IIIA and evidentiary aids such as the structured digital database, but the core investigative machinery is statutory.
What standard of proof must SEBI satisfy in an insider trading case?
The preponderance of probabilities, not proof beyond reasonable doubt. In SEBI v. Kishore R. Ajmera, (2016) 6 SCC 368, the Supreme Court held that SEBI proceedings are civil in nature and that SEBI may rely on circumstantial evidence and a logical inference from the totality of facts and circumstances, provided the inference drawn is irresistible.
Can SEBI infer communication of UPSI merely from a close family relationship?
No. In Balram Garg v. SEBI, 2022 INSC 441, the Supreme Court set aside SEBI's findings because the regulator had assumed communication of UPSI from the closeness of relationship without tangible material of actual interaction. Where the charge rests on communication under Regulation 3, foundational facts of communication must be proved, not presumed from proximity or opportunity alone.
Does SEBI have search and seizure powers, and are there safeguards?
Yes. Section 11C(8) of the SEBI Act allows the investigating authority, where it has reasonable ground to believe documents may be destroyed, altered or secreted, to apply to a designated court for an order authorising search and seizure, with the CrPC provisions applying under Section 11C(9). The procedure is detailed in the SEBI (Procedure for Search and Seizure) Regulations, 2014. Prior judicial authorisation is the principal safeguard against abuse.
Is a person under investigation entitled to see SEBI's investigation report?
Yes, once a show-cause notice is issued. In T. Takano v. SEBI (2022), the Supreme Court held that the investigation report is an intrinsic component of the Board's satisfaction and must be disclosed to the noticee; SEBI cannot withhold it by a bare assertion that it was not relied upon. Disclosure is governed by relevance, not reliance. Fair-hearing rights crystallise at the adjudication stage, not during the inquisitorial investigation.
What is the informant mechanism under the PIT Regulations?
Chapter IIIA, inserted in December 2019, created a reward-backed whistle-blower regime for insider trading. An informant who voluntarily submits a Voluntary Information Disclosure Form containing original, specific and credible information that leads to disgorgement of at least one crore rupees may receive a reward of up to ten percent of monies disgorged (subject to a cap), administered by the Informant Incentive Committee, with confidentiality and anti-retaliation protection.
