The trading prohibition in Regulation 4(1) of the SEBI (Prohibition of Insider Trading) Regulations, 2015 is drafted as a possession-based rule: no insider shall trade in listed securities when in possession of unpublished price-sensitive information (UPSI). On its face this is close to strict liability. Yet the regime is not absolute. A first proviso to Regulation 4(1) sets out four enumerated situations in which an insider charged with the offence may demonstrate his innocence; a Note builds in a rebuttable presumption that frames who bears the burden; and the parallel concept of a “legitimate purpose” under Regulations 3(2A) and 3(2B) carves communication of UPSI out of the wider Regulation 3 prohibition. Layered on top is a body of tribunal and Supreme Court authority — from Rakesh Agrawal v. SEBI to SEBI v. Abhijit Rajan — that reads motive and bona fide purpose back into an apparently mechanical offence. This chapter maps the full architecture of defences available to an insider and shows how “legitimate purpose” operates as the conceptual hinge of the entire scheme.

How the defence regime is built

To understand the defences one must first see the structure of the offence. Regulation 4(1) provides that “no insider shall trade in securities that are listed or proposed to be listed on a stock exchange when in possession of unpublished price sensitive information.” The operative trigger is possession, not proven use. SEBI deliberately chose “in possession of” over the narrower “on the basis of” that featured in earlier drafting debates, precisely to ease its evidentiary burden. The definitional gateways — who is an insider, who is a connected person, and what is UPSI — are dealt with separately in the chapter on key definitions, and must be satisfied before any question of defence arises.

Having set a wide net, the Regulations soften it in three distinct ways. First, a Note appended to Regulation 4(1) states that when a person who has traded was in possession of UPSI, his trades “would be presumed to have been motivated by the knowledge and awareness of such information.” The word presumed is the key: the presumption is rebuttable, and so it is the insider who must displace it. Second, the first proviso to Regulation 4(1) lists four enumerated circumstances in which the insider “may prove his innocence.” Third, Regulation 4(1) itself contains a further proviso preserving the trading plan defence under Regulation 5. The legitimate-purpose concept under Regulation 3 sits alongside, governing communication rather than trading. The remainder of this chapter takes each limb in turn.

The rebuttable presumption and the burden of proof

The Note to Regulation 4(1) is the pivot on which the entire defence regime turns. By presuming that an insider in possession of UPSI traded on the strength of that information, the regulation shifts the practical burden onto the insider once SEBI establishes the two objective facts of possession and a trade. The insider must then bring himself within one of the enumerated circumstances, or otherwise rebut the presumption by credible evidence that the trade was not motivated by the UPSI.

This burden architecture was anticipated by the Securities Appellate Tribunal under the predecessor 1992 Regulations. In Mrs. Chandrakala v. Adjudicating Officer, SEBI (SAT, order dated 31 December 2012), the Tribunal held that once an insider trades while in possession of UPSI, there arises a presumption — albeit a rebuttable one — that the trade was “on the basis of” that information, and the onus lies on the insider to show that the trade was not so motivated. The decision is significant because it effectively read a mental element back into a possession-based offence: the insider who can demonstrate that the trade had nothing to do with the UPSI escapes liability. The 2015 drafting absorbed this logic into the Note, converting a judge-made presumption into a textual one while leaving its rebuttable character intact. The companion concept — that possession is not automatically culpable — is also why the defences in the proviso were thought necessary at all.

Proviso clause (i): off-market inter-se transfers

The first enumerated defence, in clause (i) of the proviso to Regulation 4(1), protects an off-market inter-se transfer between insiders who were in possession of the same UPSI, provided neither party was in breach of Regulation 3 and both made a conscious and informed trade decision. The rationale is the absence of informational asymmetry: where both buyer and seller hold the identical UPSI, neither is exploiting an advantage over the other, and the integrity of the market on which the rule is premised is not impaired.

The scope of clause (i) was materially widened by the SEBI (Prohibition of Insider Trading) (Second Amendment) Regulations, 2018, which took effect on 1 April 2019. Before that amendment the defence was confined to off-market transactions between two promoters in possession of the same UPSI. The amendment replaced “promoters” with “insiders” — a far broader class that includes any connected person or any person in possession of or having access to UPSI — thereby enlarging the range of bona fide intra-group and counterparty transfers that can claim the protection. Two limits remain examinable. The onus is on the insiders to demonstrate that they held the same UPSI; and the defence is unavailable where the UPSI was conveyed under the board-sanctioned route in Regulation 3(3), since the recipient there has not independently acquired the information on equal terms.

Proviso clause (ii): the block-deal window

Clause (ii) of the proviso protects a transaction “carried out through the block deal window mechanism between persons who were in possession of the unpublished price sensitive information.” The structure mirrors clause (i): the operative idea is again symmetry of information between counterparties who have each made a conscious and informed decision to transact. The block-deal window is a recognised exchange mechanism for large negotiated trades, and SEBI treats a block trade between equally informed insiders as falling outside the mischief the prohibition targets.

The practical reach of clause (ii) has been tested through SEBI’s informal guidance mechanism, where applicants have repeatedly sought confirmation that a proposed block deal between UPSI-holders would attract the safe harbour. The recurring regulatory answer is cautious: the proviso is a defence to be raised if and when a charge is laid, not an advance exemption, and the burden of establishing common possession and the absence of any Regulation 3 breach always rests on the parties. As with clause (i), the defence collapses if the information reached one side through a leak or an impermissible communication rather than through legitimate, symmetrical possession.

Proviso clause (iii): statutory or regulatory obligation

Clause (iii) shields a transaction “carried out pursuant to a statutory or regulatory obligation to carry out a bona fide transaction.” The defence recognises that an insider may be compelled by law to transact at a time when he happens to hold UPSI, and that penalising such compelled dealing would be perverse. Typical illustrations include a mandatory open offer triggered under the Takeover Regulations, a court-directed or statutorily mandated sale, or a disposal required by a regulator. Because the transaction is not volitional in the relevant sense — the insider has no freedom to time or avoid it — the inference that he is exploiting the UPSI does not arise.

The key qualifier is that the obligation must be genuine and the transaction bona fide. An insider cannot manufacture a nominal “obligation” to dress up an opportunistic trade. The clause therefore demands that the obligation pre-exist and operate independently of the insider’s wish to deal, and that the transaction be no wider than the obligation requires.

The clause also reflects a coherence principle running through the wider securities-law framework. Where another statute or regulation positively commands a person to deal — for instance a mandatory disposal to comply with minimum-public-shareholding norms, or a sale compelled to satisfy a pledge invoked by law — it would be incoherent for the insider-trading rule to penalise the very act the law requires. Clause (iii) resolves the conflict in favour of the compelling obligation, but only so far as the obligation extends. The moment the insider exercises discretion the law did not compel — choosing, say, to sell more than required, or to time the sale to capture an advantage — the protection is lost for the discretionary excess. The defence is thus measured strictly against the contours of the obligation invoked.

Proviso clause (iv): exercise of stock options

Clause (iv) protects a transaction “undertaken pursuant to the exercise of stock options in respect of which the exercise price was pre-determined in compliance with applicable regulations.” The logic is temporal and resembles the rationale of the trading plan: where the exercise price was fixed in advance, at a time and on terms unconnected with any later-acquired UPSI, the insider cannot be said to be exploiting that information when he exercises. The price is locked; the UPSI cannot move it in his favour.

This clause is narrowly framed. It covers only the exercise of options at a pre-determined exercise price, not the subsequent sale of the shares so acquired — a sale undertaken while in possession of UPSI would itself need an independent defence. Nor does it extend to options whose pricing was contingent or discretionary. The pre-determination of price is the constitutive fact: remove it and the protection disappears.

The narrowness is deliberate and exam-relevant. The mischief the prohibition targets is the exploitation of an informational edge to extract value the insider would not otherwise obtain. Where the exercise price was fixed long ago, on terms the insider can no longer influence, the UPSI confers no edge over the exercise itself — the gain, if any, is the pre-agreed reward for holding the option, not a fruit of the inside information. But the calculus changes entirely at the point of disposal: a decision to sell the acquired shares is a fresh, discretionary trade, and if taken while holding UPSI it re-engages Regulation 4(1) in full. Candidates frequently err by assuming clause (iv) launders the whole option-to-sale chain; it does not. It protects one discrete, mechanically priced step and no more.

Are the proviso defences exhaustive?

A recurring examination question is whether the four enumerated circumstances are the only ways an insider may escape liability, or merely illustrations of a broader principle. The better view, supported by tribunal practice, is that the list is illustrative rather than exhaustive. SEBI and the SAT have accepted that an insider may rebut the Note’s presumption by other credible evidence that the trade was not motivated by the UPSI — the enumerated clauses being safe, pre-mapped routes rather than a closed code.

This reading flows naturally from the rebuttable character of the presumption itself: if the presumption can be displaced, it cannot be that only four specified facts may displace it. SEBI orders dealing with the Dynamatic Technologies matter, among others, have proceeded on the footing that the circumstances in the proviso are merely illustrative, leaving room for an insider to establish innocence on facts outside the enumerated four. The practical caution, however, is that the enumerated defences offer certainty, whereas an off-list rebuttal places a heavy and fact-specific evidentiary burden on the insider. For the foundational vocabulary that underpins every such argument, revisit the SEBI PIT notes hub.

Legitimate purpose under Regulation 3(2A)

The phrase “legitimate purpose” enters the Regulations through Regulation 3, not Regulation 4. Regulation 3(1) prohibits an insider from communicating, providing or allowing access to UPSI to any person except where the communication is in furtherance of legitimate purposes, performance of duties or discharge of legal obligations. The 2015 Regulations originally left “legitimate purposes” undefined, creating uncertainty over routine business sharing of confidential information.

The SEBI (Prohibition of Insider Trading) (Amendment) Regulations, 2018 — again effective 1 April 2019 — cured this by inserting Regulation 3(2A), which requires the board of directors of a listed company to formulate a policy for determination of “legitimate purposes” as part of the Codes of Fair Disclosure and Conduct framed under Regulation 8. An Explanation to the sub-regulation gives statutory content to the term: sharing of UPSI in the ordinary course of business by an insider with partners, collaborators, lenders, customers, suppliers, merchant bankers, legal advisors, auditors, insolvency professionals or other advisors or consultants will amount to a legitimate purpose, provided the sharing has not been carried out to evade or circumvent the prohibitions of the Regulations. The structure of the board’s code is taken up in detail in the chapter on the code of fair disclosure.

The recipient as deemed insider: Regulation 3(2B)

Regulation 3(2B) closes the loop opened by 3(2A). It provides that any person who has received or had access to UPSI pursuant to a “legitimate purpose” under Regulation 3(2A) shall be considered an insider for the purposes of the Regulations, and due notice shall be given to such persons to maintain confidentiality of the UPSI in compliance with the Regulations.

The consequence is doctrinally important and frequently examined: the legitimate-purpose route does not release the information into a safe zone; it transfers the full weight of the insider-trading regime onto the recipient. A lender, auditor or consultant who lawfully receives UPSI for a legitimate purpose is thereafter bound by the Regulation 4 trading bar and the Regulation 3 communication bar to the same extent as the original insider. Legitimate purpose, in short, justifies the communication but not any subsequent trading — a point candidates must keep firmly distinct from the trading defences in the Regulation 4 proviso.

Rakesh Agrawal v. SEBI: bona fide corporate purpose

The jurisprudential roots of the “legitimate purpose” and bona fide-motive defences lie in Rakesh Agrawal v. SEBI, (2004) 49 SCL 351 (SAT). Rakesh Agrawal was the managing director of ABS Industries Ltd. While negotiating the acquisition of a 51% stake in ABS by the German company Bayer A.G., and thus in possession of UPSI about the impending deal, he arranged — through his brother-in-law I.P. Kedia — for the purchase and tender of ABS shares ahead of the public announcement. SEBI found a violation of the 1992 Regulations and directed him to pay roughly Rs. 34 lakh by way of compensation.

The Securities Appellate Tribunal substantially diluted SEBI’s order. It accepted that Agrawal had acted not to make a personal unlawful gain but to ensure that Bayer secured the minimum 51% it required, so that the acquisition — in the interest of ABS and its shareholders — would go through. The Tribunal reasoned that the object of insider-trading law is to prevent unfair advantage, and that where an insider transacts to advance a bona fide corporate purpose rather than to exploit the informational edge for private gain, the equities are different. Rakesh Agrawal is therefore the fountainhead of the legitimate-purpose idea later codified in Regulation 3, and an essential authority for any answer on defences.

SEBI v. Abhijit Rajan: motive to make a gain is essential

The most authoritative modern statement on motive is the Supreme Court’s decision in Securities and Exchange Board of India v. Abhijit Rajan, Civil Appeal No. 563 of 2020, decided on 19 September 2022 (reported as 2022 INSC 977). Abhijit Rajan, Chairman and Managing Director of Gammon Infrastructure Projects Ltd (GIPL), had sold GIPL shares while in possession of UPSI concerning the termination of two project agreements. SEBI ordered disgorgement; the SAT set the order aside; and the Supreme Court dismissed SEBI’s appeal.

The Court’s reasoning is the heart of the defence. It observed that the terminated contracts were, on the facts, good news for GIPL’s financial position — so a person seeking to exploit the UPSI for unlawful gain would have bought, not sold. Rajan had in fact sold under financial compulsion to rescue another flagship company. The Court held that while the actual quantum of gain or loss is immaterial, the motive to make a gain is an essential element, and that the motive of the insider, the direction of the trade, and the reason for which the trade was carried out are all relevant to a charge of insider trading. Abhijit Rajan thus confirms, at the highest level, that a possession-based offence is not pure strict liability: an insider who can show that the trade lacked any motive to gain from the UPSI has a genuine defence. Students should note the academic criticism — that importing a profit-motive requirement risks blurring the deliberate “possession” standard back into a “use” standard — but the decision is binding and routinely cited.

The trading plan as a standing defence

Regulation 4(1) expressly preserves a further defence: a proviso to the sub-regulation provides that the section shall not apply to trades carried out in accordance with an approved trading plan under Regulation 5. Unlike the four enumerated circumstances, which are raised reactively once a charge is laid, the trading plan is a standing, pre-arranged defence: an insider perpetually in possession of UPSI commits in advance to a publicly disclosed, irrevocable schedule of trades, so that the eventual execution cannot be motivated by any specific UPSI then in hand.

Conceptually the trading plan and the legitimate-purpose ideas are siblings: both neutralise the inference of exploitation, one by temporal separation and advance commitment, the other by the bona fide character of the dealing. Because the trading plan has its own elaborate conditions — cooling-off, irrevocability, price limits and public disclosure, all substantially reworked by the June 2024 amendment — it is treated as a self-contained topic in the dedicated chapter on trading plans. For present purposes it suffices to locate it within the defence taxonomy: it is the one defence an insider can build before any allegation arises.

Defences for non-individual insiders: Chinese walls

Where the insider is not a natural person — a brokerage, fund manager, or other institution — the proviso to Regulation 4(1) supplies a tailored defence. A non-individual insider may demonstrate that the individuals who actually took the trading decision were not in possession of the UPSI when they traded, and that appropriate and adequate arrangements were in place — in substance, an effective “Chinese wall” or information barrier — to ensure that the Regulations were not violated, and that no UPSI was communicated by the persons possessing it to the persons taking the trading decision.

The defence recognises a commercial reality: a large institution may unavoidably hold UPSI in one department (say, an advisory desk) while an entirely separated department trades on its own account. If the firm can prove genuine segregation — documented information barriers, restricted lists, surveillance, and no leakage — the trading decision is untainted and the firm escapes liability. The burden, predictably, is on the institution to establish that the barriers were real and effective rather than nominal, and that the decision-makers were in fact walled off from the UPSI.

Common pitfalls and how the defences interlock

Several traps recur in answers on this topic. First, the proviso defences are defences, not exemptions: they are raised after a charge is laid and the burden of establishing them lies on the insider, who must also show no breach of Regulation 3. They do not pre-clear a trade. Second, legitimate purpose under Regulation 3(2A) justifies communication only; the recipient is deemed an insider under 3(2B) and remains fully bound by the Regulation 4 trading bar. Confusing the communication defence with a trading defence is a classic error.

So is conflating the four enumerated circumstances with the trading plan. Third, the clause (i) and (ii) defences depend on symmetry of information between counterparties; if the information reached one side through a leak, the symmetry — and the defence — evaporates. Fourth, motive jurisprudence (Rakesh Agrawal, Abhijit Rajan) supplies a residual, off-list route to rebut the Note’s presumption, but it is fact-heavy and uncertain; candidates should present it as a principle rebutting the presumption rather than as a fifth enumerated clause. Read alongside the definitions and the trading-plan chapters, the defence regime forms a coherent, layered whole rather than a scatter of unrelated exceptions.

Exam pointers and quick recap

For judiciary and CLAT-PG candidates, anchor the answer on the architecture. Regulation 4(1) is a possession-based prohibition; its Note creates a rebuttable presumption that the trade was motivated by the UPSI, shifting the burden to the insider. The first proviso lists four enumerated defences: (i) off-market inter-se transfers between insiders holding the same UPSI (widened from “promoters” to “insiders” with effect from 1 April 2019); (ii) block-deal-window transactions between UPSI-holders; (iii) transactions pursuant to a statutory or regulatory obligation; and (iv) exercise of stock options at a pre-determined price. A separate proviso preserves the Regulation 5 trading-plan defence, and the proviso supplies an information-barrier defence for non-individual insiders.

On communication, distinguish “legitimate purpose” under Regulation 3(1) and 3(2A) — the board must frame a policy listing categories such as lenders, auditors, advisors and consultants — and remember that under 3(2B) the recipient becomes a deemed insider. On principle, cite Mrs. Chandrakala v. SEBI (2012, rebuttable presumption), Rakesh Agrawal v. SEBI, (2004) 49 SCL 351 (SAT) (bona fide corporate purpose), and SEBI v. Abhijit Rajan (2022 INSC 977; 19 September 2022) (motive to make a gain is essential; direction of trade is relevant). Close by stressing that the enumerated defences are best understood as illustrative safe routes, not an exhaustive code.

Frequently asked questions

What are the four defences listed in the proviso to Regulation 4(1) of the SEBI PIT Regulations, 2015?

The first proviso lists four enumerated circumstances in which an insider may prove innocence: (i) an off-market inter-se transfer between insiders who were in possession of the same UPSI without breach of Regulation 3; (ii) a transaction through the block-deal window between persons in possession of the UPSI; (iii) a transaction carried out pursuant to a statutory or regulatory obligation to carry out a bona fide transaction; and (iv) a transaction undertaken pursuant to the exercise of stock options where the exercise price was pre-determined. A separate proviso also preserves the Regulation 5 trading-plan defence.

What does "legitimate purpose" mean under the PIT Regulations?

Under Regulation 3(1), communicating UPSI is permitted where it is in furtherance of legitimate purposes, performance of duties or discharge of legal obligations. Regulation 3(2A), inserted with effect from 1 April 2019, requires the board to frame a policy defining legitimate purposes. Its Explanation states that sharing UPSI in the ordinary course of business with partners, collaborators, lenders, customers, suppliers, merchant bankers, legal advisors, auditors, insolvency professionals or other advisors or consultants is a legitimate purpose, provided it is not done to circumvent the Regulations.

Does receiving UPSI for a legitimate purpose make you an insider?

Yes. Regulation 3(2B) provides that any person who receives or has access to UPSI pursuant to a legitimate purpose under Regulation 3(2A) is considered an insider, and must be given notice to maintain confidentiality. Legitimate purpose justifies the communication of UPSI, but the recipient is then fully bound by the trading prohibition in Regulation 4 and the communication bar in Regulation 3.

Is the trading by an insider in possession of UPSI strict liability?

Not entirely. Regulation 4(1) is possession-based and the Note creates a presumption that the trade was motivated by the UPSI, but the presumption is rebuttable. In SEBI v. Abhijit Rajan (2022 INSC 977) the Supreme Court held that while the quantum of gain or loss is immaterial, the motive to make a gain is an essential element, and the direction of the trade and the reason for it are relevant. An insider who shows the trade lacked any motive to exploit the UPSI has a genuine defence.

How did the 2019 amendment change the inter-se transfer defence?

Before 1 April 2019, clause (i) of the proviso protected only off-market inter-se transfers between two promoters in possession of the same UPSI. The 2018 amendment, effective 1 April 2019, replaced "promoters" with "insiders", widening the defence to any connected persons or persons in possession of the same UPSI. The defence remains unavailable where the UPSI was conveyed under the board-sanctioned route in Regulation 3(3), and the onus is on the parties to prove common possession.

What is the significance of Rakesh Agrawal v. SEBI for the defence of legitimate purpose?

Rakesh Agrawal v. SEBI, (2004) 49 SCL 351 (SAT), is the jurisprudential origin of the legitimate-purpose idea. The managing director of ABS Industries traded ahead of a Bayer acquisition announcement, but the Securities Appellate Tribunal accepted that he acted to ensure Bayer secured its required 51% stake in the interest of the company and its shareholders, rather than for personal unlawful gain, and diluted SEBI's order. The case established that a bona fide corporate purpose can negate the culpability of trading while in possession of UPSI.
