No part of Indian securities law has been shaped more by adjudication than the takeover regime. The Securities Appellate Tribunal (SAT) and the Supreme Court have repeatedly supplied the content that the bare regulations leave open — what "control" means, when parties are "acting in concert", how indirect acquisitions are priced, and whether an open offer once announced can ever be withdrawn. The cases below were decided largely under the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 1997, but they remain authoritative for the 2011 Code because the operative concepts — trigger thresholds, PAC, control and the sanctity of the public announcement — were carried forward almost verbatim. For the judiciary and CLAT-PG aspirant, mastering this case-law is non-negotiable: examiners test the holdings far more than the regulation numbers. This chapter walks through the leading authorities theme by theme, with verified citations, so you can deploy each one precisely.
Why case-law dominates this subject
The SEBI Takeover Code is unusually litigation-heavy. The regulations fix bright-line numbers — the 25% threshold, the 5% creeping limit, the 26-week offer window — but the most consequential terms are deliberately open-textured. "Control" is defined inclusively; "persons acting in concert" turns on shared purpose; "indirect acquisition" requires courts to look through corporate layers. Each of these phrases has been litigated to the Supreme Court, and the resulting holdings now function as the real rulebook. A candidate who recites the definitions but cannot cite Daiichi Sankyo on concert or Subhkam Ventures on control has learned only half the subject.
Three institutional features explain the volume of authority. First, every open offer is a high-value, time-sensitive transaction, so disputes are fought hard and appealed fast. Second, SAT sits as a specialised appellate forum whose orders carry persuasive weight even when later left open by the Supreme Court. Third, SEBI's own interpretive orders — informal guidance, exemption orders, adjudication orders — feed a constant stream of appeals. The result is a body of precedent that an aspirant must read alongside the bare provisions, never in isolation. This chapter is best studied after the trigger for an open offer and the hub overview at the SEBI Takeover Code notes hub.
Subhkam Ventures: the control test
The single most cited takeover authority on "control" is Subhkam Ventures (I) Pvt. Ltd. v. SEBI, decided by SAT on 15 January 2010 (Appeal No. 8 of 2009). Subhkam, a private-equity investor, subscribed to more than 15% of MSK Projects (India) Ltd. and, through a shareholders' agreement, secured a board nominee, a quorum-presence right for that nominee, and a clutch of affirmative (veto) rights over corporate actions such as amending the charter, issuing securities, and altering the business. SEBI took the view that these rights amounted to "control" and that the open offer should be priced and worded accordingly.
SAT disagreed and laid down what became the governing distinction. Control, it held, means the ability to control the affairs of a company in the proactive and not the reactive sense. Positive control — the power to direct management, set policy and run the company — triggers the takeover obligations; negative or protective rights, which merely allow an investor to block value-destroying actions and safeguard its capital, do not. Affirmative vetoes, board representation and quorum rights, SAT reasoned, are defensive shields routinely sought by financial investors and do not let the investor steer the enterprise. This "positive control" reading was a watershed for private-equity and PIPE deals, freeing investors to negotiate customary protections without inadvertently triggering a mandatory offer. The holding feeds directly into how the trigger for an open offer is assessed whenever control, rather than the 25% number, is the alleged trigger.
Subhkam in the Supreme Court: a precedent un-set
SEBI appealed the SAT order to the Supreme Court in SEBI v. Subhkam Ventures (I) Pvt. Ltd., Civil Appeal No. 3371 of 2010. By the time the matter was heard, Subhkam had exited its investment, so the live controversy had evaporated. On 16 November 2011 the Court, by consent of the parties, disposed of the appeal while expressly keeping the question of law open and directing that the SAT order "will not be treated as a precedent".
The consequence is subtle but important for examinations. The substantive SAT reasoning — the positive-versus-negative control distinction — was neither affirmed nor overruled; it was simply stripped of binding force. For years this left "control" in a doctrinal limbo: SEBI continued to argue that protective covenants could amount to control, while practitioners relied on the persuasive logic of Subhkam. The lesson for candidates is to state the holding accurately and then add the caveat that the Supreme Court declined to crown it as precedent — a nuance that distinguishes a careful answer from a careless one. The unsettled state of the law also explains why SEBI's own definition in the definitions chapter remains inclusive and fact-driven.
The NDTV ruling and the revival of positive control
Because Subhkam was denied precedential status, the question kept returning. The most significant later treatment came in the NDTV litigation, where SAT in 2022 set aside SEBI's finding that VCPL had acquired "control" of New Delhi Television Ltd. through loan agreements granting it sweeping affirmative rights and a call option over RRPR Holding's shares. SAT reaffirmed the Subhkam approach, holding that negative or protective covenants — consents required for charter amendments, fresh issuances and borrowings — are not in the nature of day-to-day operational or policy control and therefore do not constitute "control" for the Takeover Regulations.
The NDTV order is valuable in an answer precisely because it shows the Subhkam test alive and applied notwithstanding its loss of precedential status. Aspirants should present the line of authority as a trajectory: Subhkam articulated positive control, the Supreme Court left it open, and SAT in the NDTV matter restored its practical primacy. Examiners reward candidates who can show that the "control" debate is contested rather than closed, and who appreciate that an inclusive statutory definition invites exactly this kind of judicial gloss.
Rhodia and Clearwater: control in different fact-settings
Two further SAT decisions round out the control jurisprudence and are worth deploying for contrast. In Rhodia S.A. v. SEBI, SAT found that Rhodia — though not itself a shareholder of the Indian target — could control the step-up parent (Danube) through contractual veto rights over dividends, asset disposals and securities issuance, coupled with its funding of and direction over the acquisition bid. The case illustrates that control can be exercised through the corporate chain and is fact-intensive, dovetailing with the look-through analysis examined in indirect acquisition.
In the Clearwater Capital litigation arising from the Kamat Hotels (India) matter, the investor held convertible bonds and, after restructuring, secured affirmative rights under an inter-se agreement. SEBI and SAT scrutinised whether those rights crossed from protection into control. SEBI's later wholetime-member order in the Kamat Hotels matter (31 March 2017) reiterated that the "existence of protective rights to safeguard one's investments cannot be construed to be acquisition of control", expressly drawing on Subhkam. Read together, Rhodia and the Kamat Hotels line show that the same vocabulary — veto, affirmative, protective — yields different results depending on whether the rights are genuinely defensive or are a vehicle for steering the enterprise.
Daiichi Sankyo: defining persons acting in concert
The leading Supreme Court authority on "persons acting in concert" (PAC) is Daiichi Sankyo Co. Ltd. v. Jayaram Chigurupati, (2010) 7 SCC 449. Daiichi acquired Ranbaxy under a Share Purchase and Share Subscription Agreement dated 11 June 2008, thereby becoming the acquirer of Ranbaxy directly and of Zenotech Laboratories Ltd. indirectly. The dispute was about the price Daiichi had to offer Zenotech's public shareholders. Crucially, Ranbaxy had itself bought Zenotech shares in January 2008, before Daiichi entered the picture; objectors argued that the high price paid by Ranbaxy should set the floor for Daiichi's offer because Ranbaxy and Daiichi were PAC.
The Court rejected this. It held that to be persons acting in concert, parties must actually come together with the shared common objective or purpose of substantial acquisition of shares of a particular target company, pursuant to an agreement or understanding. The relationship is not static: PAC status exists only for the duration of, and in relation to, that shared purpose. When Ranbaxy bought Zenotech shares in January 2008, Daiichi was nowhere in the picture and there was no common objective; the two could not be retrospectively deemed to have acted in concert merely because Ranbaxy later became Daiichi's subsidiary. The deeming provisions that treat holding and subsidiary companies as PAC do exactly that — they deem — but they do not manufacture a shared purpose that never existed. The judgment is the bedrock of any answer on PAC and pairs naturally with the definitions chapter.
Daiichi on indirect acquisition pricing
Daiichi Sankyo also clarified offer pricing in indirect ("chain") takeovers. Because Ranbaxy and Daiichi were not PAC at the relevant time, the price Ranbaxy had earlier paid for Zenotech could not be imported as the benchmark for Daiichi's indirect offer to Zenotech shareholders. The relevant parameters were those tied to Daiichi's own triggering acquisition of Ranbaxy and the consequent indirect acquisition of Zenotech, not an unrelated earlier purchase by a company that only afterwards became a subsidiary.
This holding matters because indirect acquisitions are priced by reference to the negotiated price and prevailing market parameters at the date the underlying transaction is agreed, looking through to the listed Indian target. The 2011 Code later codified detailed pricing and "deemed direct" rules for indirect acquisitions, but the conceptual spine — identify the genuine acquirer, the genuine triggering event and the genuine concert party — descends from Daiichi. Candidates should connect this to the mechanics discussed in indirect acquisition and the threshold logic in the 25% substantial-acquisition threshold.
Technip SA: control, foreign law and the trigger date
Technip S.A. v. SMS Holding (P) Ltd., (2005) 5 SCC 465, is the Supreme Court's earliest substantial engagement with the control concept under the 1997 Regulations. Technip, a French company, acquired Coflexip, another French company, which in turn held a controlling stake in the Indian listed company SEAMEC. The contest was whether and when Technip acquired "control" of SEAMEC such that an open offer was owed, and at what date that control crystallised — April 2000 or July 2001.
The Court held that because both Technip and Coflexip were incorporated in France, the question of when control over Coflexip (and hence indirectly over SEAMEC) passed was to be determined by the law of the domicile, i.e. French law. This conflict-of-laws holding remains the textbook authority for the proposition that the acquisition of control over a foreign intermediary is governed by the intermediary's own corporate law, even though the downstream consequence — the open-offer obligation for the Indian target — is governed by SEBI's Regulations. Technip is therefore a foundational indirect-acquisition and control case, and an examiner-favourite for its neat intersection of company law, conflict of laws and securities regulation.
The Court also offered a broader exposition of "control", treating it as the capacity to appoint a majority of directors or to control management or policy, whether directly or through shareholding, management or voting agreements. That formulation prefigured the inclusive definition later used by SEBI and shows that the control inquiry has, from the outset, been substance-driven rather than tied to any single numerical threshold. For aspirants, the case is best remembered as a triad of propositions: control is functional, not merely numerical; the timing of control acquisition over a foreign holding company is governed by that company's domestic law; and the obligation to make an open offer for the listed Indian company flows automatically once that control is shown to have passed.
Nirma Industries: you cannot walk away from an open offer
The sanctity of a public announcement is the theme of Nirma Industries Ltd. v. SEBI, (2013) 8 SCC 20. Nirma had announced an open offer for Shree Rama Multi-Tech and then sought to withdraw it, invoking Regulation 27(1)(d) of the 1997 Regulations — the residual ground permitting withdrawal in "circumstances" that SEBI considers merit it — on the basis that it had discovered fraud and embezzlement by the target's promoters after the announcement.
The Supreme Court refused. It read Regulation 27(1)(d) ejusdem generis with the specific preceding grounds, which all involve genuine, supervening impossibility of performance (such as a statutory refusal of a required approval). Subsequent discovery of fraud, or the deal becoming commercially unattractive, does not make performance impossible; an acquirer is responsible for its own pre-announcement diligence and bears the risk of what it later finds. The Court thus cemented an impossibility-based, narrowly construed power of withdrawal, ensuring that public shareholders who rely on an announced exit are protected. This holding is the analytical heart of the open-offer obligation and should be read with the trigger for an open offer.
Akshya Infrastructure: even voluntary offers bind
SEBI v. Akshya Infrastructure Pvt. Ltd., (2014) 11 SCC 112, extended the Nirma principle to voluntary open offers. Akshya had voluntarily announced an offer for Marg Ltd. and then sought to withdraw it after a prolonged delay — some thirteen months — in SEBI's clearance of the offer documents had, it argued, made the offer commercially uneconomical. SAT had allowed the withdrawal; SEBI appealed.
The Supreme Court reversed SAT and disallowed the withdrawal. Relying heavily on Nirma, it held that the strict, impossibility-based reading of the withdrawal power applies equally to voluntary offers; the public announcement, once made, is not a unilateral instrument the acquirer may abandon when economics turn against it. Significantly, the Court held that delay by SEBI in processing the offer — here partly attributable to SEBI's discovery of an earlier breach by the acquirer — does not by itself justify withdrawal, though it may have other consequences. The twin holdings of Nirma and Akshya together establish the rule that an open offer, mandatory or voluntary, is a near-irrevocable commitment to the target's public shareholders.
The policy rationale the Court emphasised is investor protection. The open offer exists to give public shareholders an exit at a fair price when control of their company changes hands; if acquirers could announce and then retreat whenever the economics soured, the announcement would become a costless option that distorts the market and defeats the regulatory purpose. The Court was alive to the hardship this causes acquirers caught by adverse post-announcement developments, but it located the remedy in pre-announcement diligence and in the limited statutory exceptions, not in a roving judicial discretion to release acquirers from their word. Candidates should articulate this balance — certainty for the market and protection for minority shareholders, weighed against the acquirer's commercial risk — because it is the doctrinal thread linking both judgments and the 2011 Code's correspondingly narrow withdrawal grounds.
Delay and proportionality: the Rajeev Bhanot line
If Nirma and Akshya protect shareholders against acquirers walking away, a counter-current protects acquirers against stale enforcement. In SEBI v. Rajeev Bhanot (decided 11 November 2021), the Supreme Court declined to interfere with a SAT order quashing a SEBI direction to make an open offer, on the ground of inordinate delay: SEBI had issued its show-cause notice roughly twelve years after the acquisition in financial year 2005-06. The Court treated such an unexplained, gross delay as fatal to the proportionality and fairness of the direction.
This line teaches that the open-offer obligation, though stringent, is not enforceable in perpetuity without regard to delay and prejudice. For an aspirant, the value lies in balance: cite Nirma and Akshya for the sanctity of the offer, then cite the Bhanot approach to show that enforcement itself must be timely and reasonable. The same fairness instinct underlies the interest-on-delay jurisprudence, under which acquirers who belatedly perform an offer have been directed to pay interest to compensate shareholders for the deferred exit.
Pyramid Saimira: fraud dressed as a takeover
The Pyramid Saimira saga shows the takeover machinery being weaponised for market manipulation. In December 2008, media reports circulated a purported SEBI letter directing promoter P.S. Saminathan to make an open offer for Pyramid Saimira Theatre Ltd. at a price floor said to be around Rs 250, allegedly for breaching creeping-acquisition norms. SEBI had issued no such letter; it was forged. The fabricated "direction" spiked the scrip, allowing the masterminds to offload shares at inflated prices.
SEBI's investigation traced the forgery to Nirmal Kotecha, then the largest shareholder and the largest seller on both exchanges on the relevant day. SEBI passed a final order against Kotecha on 22 March 2018 imposing a long market ban and disgorgement, which SAT upheld by its order dated 2 March 2020, and the matter was carried unsuccessfully further. The case is a cautionary tale for the takeover student: the open-offer mechanism, because it can move prices sharply, is itself a target for fraudulent and unfair-trade-practice abuse, and SEBI's PFUTP and takeover powers operate in tandem to police it.
Arbutus: literal reading of exemptions and the limits of informal guidance
Arbutus Consultancy LLP v. SEBI is the leading SAT decision on the strict construction of exemption provisions under the 2011 Code. The dispute concerned the inter-se transfer exemption in Regulation 10(1)(a) for transfers among qualifying persons, which requires that the transferor and transferee have been disclosed as such for a defined period. SAT held that the exemption's conditions must be read literally: the qualifying period must be satisfied post-listing and cannot be made out by counting pre-listing status, because the regulation's language is clear and an exemption is to be construed strictly against the party claiming it.
Equally important, SAT held that informal guidance issued by a SEBI department is not binding on SEBI and cannot dilute the statutory language, nor is such guidance an appealable "order". The case is a reminder that the generous-sounding exemptions which dot the Code — and which interact with the numbers discussed in creeping acquisition — are construed narrowly, and that practitioners cannot rely on soft guidance to escape the rigour of the text.
How to deploy these authorities in an answer
For prelims, fix the holdings to the case names: Subhkam — positive (not negative) control; Daiichi — PAC requires a shared purpose and is target-specific; Technip — control over a foreign intermediary is judged by foreign law; Nirma and Akshya — open offers, mandatory or voluntary, cannot be withdrawn save for genuine impossibility. For mains and viva, structure the answer thematically — control, concert, indirect acquisition, withdrawal, enforcement — and within each theme show the trajectory of the law rather than a flat list of cases.
Always flag the precedential nuances: Subhkam's SAT reasoning was left open by the Supreme Court but revived in practice by the NDTV order; Daiichi turned on the specific facts of when concert arose. Tie every case back to the governing concept — revisit the trigger for an open offer and the 25% threshold — so the case-law reads as an application of the Code, not a parallel syllabus. Candidates who can move fluently between the bare regulation and its judicial gloss consistently outperform those who memorise one without the other.

Frequently asked questions
What did SAT actually hold about control in Subhkam Ventures v SEBI?
In Subhkam Ventures (I) Pvt. Ltd. v. SEBI (SAT, 15 January 2010), the tribunal held that control means the ability to control a company's affairs in a proactive, positive sense — the power to run management and set policy. Protective or negative rights such as board nominee seats, quorum rights and affirmative vetoes against value-destroying actions do not amount to control and so do not trigger the open-offer obligation.
Is the Subhkam control test binding precedent?
No. SEBI appealed to the Supreme Court in SEBI v. Subhkam Ventures, Civil Appeal No. 3371 of 2010. Because the investor had exited, the Court on 16 November 2011 disposed of the appeal by consent, kept the question of law open, and directed that the SAT order "will not be treated as a precedent". The reasoning therefore carries persuasive value but not binding force, though SAT applied it again in the NDTV matter in 2022.
How did Daiichi Sankyo define persons acting in concert?
In Daiichi Sankyo Co. Ltd. v. Jayaram Chigurupati, (2010) 7 SCC 449, the Supreme Court held that persons acting in concert must actually come together with a shared common objective of substantially acquiring a particular target's shares, pursuant to an agreement or understanding. The status is target-specific and time-bound; parties cannot be retrospectively deemed to have acted in concert merely because one later became a subsidiary of the other.
Can an acquirer withdraw an open offer once announced?
Only in narrow circumstances amounting to genuine impossibility. In Nirma Industries Ltd. v. SEBI, (2013) 8 SCC 20, the Supreme Court read the withdrawal power (Regulation 27(1)(d) of the 1997 Code) ejusdem generis with grounds of supervening impossibility and refused withdrawal based on later-discovered promoter fraud. In SEBI v. Akshya Infrastructure Pvt. Ltd., (2014) 11 SCC 112, the Court extended this to voluntary offers, holding that the deal becoming uneconomical does not justify withdrawal.
Why is Technip SA v SMS Holding important?
In Technip S.A. v. SMS Holding (P) Ltd., (2005) 5 SCC 465, two French companies (Technip and Coflexip) were involved and the dispute was when control over Coflexip — and hence indirectly over the Indian listed company SEAMEC — passed. The Supreme Court held that the acquisition of control over the foreign intermediary is determined by the law of its domicile, here French law, while the open-offer obligation for the Indian target remains governed by SEBI's Regulations.
Does delay by SEBI affect enforcement of the open-offer obligation?
Delay does not let an acquirer walk away — Akshya Infrastructure made that clear — but gross, unexplained delay by SEBI in enforcement can defeat its own direction. In SEBI v. Rajeev Bhanot (Supreme Court, 11 November 2021), the Court declined to disturb a SAT order quashing an open-offer direction issued about twelve years after the 2005-06 acquisition, treating the inordinate delay as fatal.
