Most of the Competition Act, 2002 polices conduct after the fact — a cartel that has already fixed prices, a dominant firm that has already abused its position. Combination control is different: it is the only ex ante, preventive arm of the statute. Sections 5 and 6 ask the regulator to look at a merger, acquisition or amalgamation before it happens and decide whether the new, more concentrated market structure is likely to harm competition. Section 5 supplies the gatekeeping arithmetic — which deals are large enough to be "combinations" at all — and Section 6 supplies the substantive prohibition and the procedural machinery of notice, standstill and review by the Competition Commission of India (CCI). For judiciary and CLAT-PG aspirants this pairing is heavily examined because it weaves together statutory thresholds, the concept of appreciable adverse effect on competition (AAEC), and a now-rich body of "gun-jumping" case law from the Supreme Court.
The scheme: why a separate regime for combinations
The Act addresses three mischiefs through three pillars: anti-competitive agreements under Section 3 (treated in detail in our notes on horizontal agreements and vertical agreements), abuse of dominance under Section 4, and combinations under Sections 5 and 6. The first two are behavioural and reactive. Combination control is structural and anticipatory — it intervenes at the moment market structure is about to change, because once a merger is consummated and assets, employees and customer relationships are integrated, an order to "un-scramble the eggs" is far harder to enforce than a simple cease-and-desist.
The logic is straightforward. A merger reduces the number of independent decision-makers in a market. Fewer players can mean higher prices, reduced output, less innovation or a heightened risk of coordinated behaviour. But mergers also generate efficiencies — economies of scale, better access to capital, technology transfer. The statute therefore does not ban mergers; it filters them. Section 5 filters by size (only large transactions are caught), and Section 6 filters by effect (only those likely to cause AAEC are prohibited). A combination that crosses the Section 5 thresholds but is competitively harmless must be — and routinely is — cleared.
This is why combination control is described as a regime of suspensory notification: the parties must notify the CCI and then wait. They cannot complete the deal until the Commission approves it or the statutory clock runs out. The waiting obligation is the spine of the whole regime, and almost every reported dispute — from Thomas Cook to Amazon — turns on whether that obligation was honoured.
Section 5: the definition of a "combination"
Section 5 defines "combination" exhaustively. A combination arises from any of three transaction types: (a) the acquisition of control, shares, voting rights or assets of one or more enterprises; (b) the acquiring of control by a person already controlling an enterprise engaged in a similar or identical business, over another enterprise (the "acquiring of control" limb); and (c) any merger or amalgamation of enterprises. Crucially, a transaction is a notifiable combination only if it also breaches the financial thresholds set out in the section. A small acquisition — however structurally significant in a niche market — simply falls outside the regime.
The thresholds operate at two levels. At the parties (or enterprise) level the test looks at the combined assets or turnover of the acquirer and target taken together. At the group level the test looks at the group to which the target will belong post-acquisition. The thresholds are expressed both in Indian rupees (for purely domestic operations) and in a rupee-plus-foreign-currency form (for transactions with a foreign element), capturing global deals that have a meaningful Indian footprint. The drafting deliberately uses the disjunctive "or": breaching either the asset limb or the turnover limb at the relevant level is enough to make the deal notifiable.
For the precise figures, note that the thresholds are not frozen in the bare Act. Section 20(3) empowers the Central Government, on the CCI's recommendation, to revise them every two years to account for changes in wholesale price index or exchange rate, which is exactly what has happened. The current figures (notified in March 2024) are set out in the next section, and aspirants should always state both the structure of the test and the live numbers.
The threshold figures: original and revised (2024)
As originally notified, the enterprise-level thresholds required combined assets in India exceeding Rs 1,000 crore or combined turnover in India exceeding Rs 3,000 crore; the group-level thresholds were assets exceeding Rs 4,000 crore or turnover exceeding Rs 12,000 crore. For transactions with a worldwide element, the enterprise-level test was assets of more than USD 500 million (with at least Rs 500 crore in India) or turnover of more than USD 1,500 million (with at least Rs 1,500 crore in India), and the group test was USD 2 billion in assets or USD 6 billion in turnover, subject to the same India minimums.
The Ministry of Corporate Affairs revised these figures by notification dated 7 March 2024 (effective 1 May 2024), substantially raising them as an ease-of-doing-business measure. The current enterprise-level thresholds are: assets in India exceeding Rs 2,500 crore or turnover in India exceeding Rs 7,500 crore; with worldwide tests of USD 1.25 billion in assets (minimum Rs 1,250 crore in India) or USD 3.75 billion in turnover (minimum Rs 3,750 crore in India). The group-level thresholds are now assets in India exceeding Rs 10,000 crore or turnover exceeding Rs 30,000 crore; with worldwide tests of USD 5 billion in assets or USD 15 billion in turnover, subject to the same India minimums.
The practical effect is that only genuinely large transactions are caught. A foreign-to-foreign merger between two multinationals with negligible Indian assets and turnover — below the India minimums — falls outside Section 5 entirely, even though both companies are enormous globally. This India-nexus requirement is a recurring favourite in problem questions: the size of the parties worldwide is irrelevant unless the Indian-leg minimums are also crossed.
The de minimis (small target) exemption
Layered on top of Section 5 is the so-called de minimis or "small target" exemption, granted by the Central Government under Section 54 of the Act. It exempts from the notification requirement any acquisition where the target enterprise — the enterprise whose control, shares, voting rights or assets are being acquired — has assets in India not exceeding a specified ceiling, or turnover in India not exceeding a specified ceiling. The rationale is that acquiring a very small business cannot meaningfully alter market structure, so it would be wasteful to require a full CCI filing.
The exemption figures were also revised by the March 2024 notification and now stand at target assets in India of up to Rs 450 crore or target turnover in India of up to Rs 1,250 crore (the asset figure having been raised from the earlier Rs 350/400 crore band). The exemption is granted for a rolling period — most recently extended so that it continues to apply to transactions over a multi-year window — and aspirants should describe it functionally rather than fixating on a single date, since it is renewed periodically.
Two cautions are essential. First, the exemption attaches to the target, not to the combined entity — a giant acquirer buying a tiny target can claim it. Second, the deal value threshold introduced in 2023 (discussed below) overrides the de minimis logic for high-value digital and similar transactions: a deal can be exempt on asset and turnover figures yet still notifiable because of its sheer transaction value. This interaction between the size-of-target exemption and the size-of-deal threshold is the modern frontier of Indian merger control.
The deal value threshold (2023 amendment)
The Competition (Amendment) Act, 2023 inserted a new deal value threshold (DVT) into Section 5. The amendment responded to the "killer acquisition" problem: in the digital economy, a dominant platform may pay billions to acquire a nascent rival that has almost no assets or turnover yet — and therefore escapes the traditional Section 5 net entirely. The classic example is a large technology firm buying a fast-growing start-up before it can mature into a competitive threat.
Under the new provision, a transaction is a notifiable combination, regardless of the asset and turnover thresholds, if (i) the value of the transaction exceeds Rs 2,000 crore, and (ii) the target enterprise has substantial business operations in India as specified by regulations. The CCI's Combination Regulations elaborate "substantial business operations," using metrics such as the number of Indian users, subscribers or visitors, or the proportion of the enterprise's global users or gross merchandise value attributable to India. The amendment came into force in a staggered manner, with the merger-control provisions including the DVT notified with effect from September 2024.
The DVT marks a structural shift: India now joins jurisdictions like Germany and Austria in supplementing turnover-based tests with a value-based test designed specifically for digital markets. For examination purposes, link the DVT to the broader debate about whether traditional thresholds — built around turnover and asset metrics — can capture data-driven competitive harm where the target's commercial value lies in users and data rather than revenue.
Section 6(1): the substantive prohibition
Section 6(1) contains the operative prohibition: no person or enterprise shall enter into a combination which causes or is likely to cause an appreciable adverse effect on competition within the relevant market in India, and such a combination shall be void. Two features deserve emphasis. First, the test is forward-looking — "causes or is likely to cause" — so the CCI assesses probable future effects, not merely realised harm. Second, the consequence of a prohibited combination is not merely a penalty but voidness: a combination that the CCI finds likely to cause AAEC and refuses to clear cannot lawfully take effect.
The AAEC inquiry under Section 6 is not free-floating. The CCI assesses it against the factors enumerated in Section 20(4), which include the level of combination in the market, the degree of countervailing power in the market, the likelihood that the combination would result in the parties being able to significantly and sustainably increase prices or profit margins, the extent of effective competition likely to sustain in the market, the extent of barriers to entry, the nature and extent of vertical integration, the possibility of a failing business, and the nature and extent of innovation. These factors mirror the AAEC analysis used for agreements under Section 19(3), giving the statute an internally consistent vocabulary for measuring competitive harm.
It is the breadth of these factors that allowed the CCI in Jet Airways–Etihad to define a granular "relevant market" — origin-and-destination city pairs for air travel — and to scrutinise overlapping routes for AAEC, ultimately clearing the deal subject to behavioural conditions. The relationship between combination review and the definition of the relevant market is therefore intimate: the narrower the relevant market, the more likely a combination produces a problematic concentration within it.
Section 6(2) and 6(2A): mandatory notice and standstill
Section 6(2) is the procedural heart of the regime. It requires any person or enterprise proposing to enter into a combination to give notice to the Commission, in the prescribed form and with the prescribed fee, disclosing the details of the proposed combination. The trigger for filing is the execution of any agreement or other document for acquisition (under the acquisition limbs) or the approval of the proposal by the board of directors (in the case of a merger or amalgamation).
Section 6(2A) imposes the standstill obligation: no combination shall come into effect until the expiry of the statutory waiting period (calculated from the date of notice) or until the CCI has passed orders, whichever is earlier. The statutory outer limit has historically been 210 days, though the CCI is required in practice to form a prima facie opinion within 30 working days (Phase I) and to complete its review well within the outer limit; the 2023 amendment further compressed these timelines to speed up clearances. The combined effect of Sections 6(2) and 6(2A) is the suspensory regime: notify, then wait, then close.
Violation of these obligations is "gun-jumping" — completing or partially completing a notifiable combination before clearance, or failing to notify at all. Gun-jumping is sanctioned under Section 43A, which empowered the CCI to impose a penalty of up to one per cent of the total turnover or assets of the combination, whichever is higher (the cap was raised by the 2023 amendment from the original formulation that referenced turnover or assets). Because the penalty is a percentage of the entire combination's turnover or assets — not of any profit or harm — it can be very large, which is why the gun-jumping case law is so consequential.
Gun-jumping and composite transactions: Thomas Cook and SCM Soilfert
The foundational gun-jumping authorities are Thomas Cook (India) Ltd. v. Competition Commission of India and SCM Soilfert Ltd. v. Competition Commission of India, decided together by the Supreme Court on 17 August 2018. In Thomas Cook, the acquirer made on-market purchases of roughly 10% of the target's shares before filing its combination notice, as part of a larger scheme that also involved an amalgamation. The CCI held that the market purchases were an interconnected, interdependent part of a single composite transaction, and that consummating that part before notification breached Section 6(2). It imposed a penalty under Section 43A. The Supreme Court upheld the CCI's approach, confirming that where a series of steps forms one composite transaction, a party cannot consummate one limb in advance and then notify the rest.
In SCM Soilfert, the acquirer similarly made open-market purchases of shares and only later filed notice in respect of the broader acquisition. The Supreme Court again upheld the CCI's penalty, reasoning that notice under Section 6(2) must be given prior to the consummation of the acquisition, and that the Combination Regulations reinforce this reading. Both decisions establish the doctrine of composite transactions: the CCI will look at the commercial substance of a deal as a whole, and interdependent steps that together amount to acquiring the target cannot be artificially severed to avoid or defer the standstill obligation.
The practical lesson the Court drove home is that even full and honest disclosure after the fact does not cure a gun-jumping violation. In Thomas Cook the parties had disclosed the market purchases in their notice and there was no attempt to conceal, yet a penalty still followed, because the breach lay in the timing of consummation, not in any deception. Standstill is an absolute procedural obligation, not a disclosure obligation.
The limits of Section 43A: Amazon v. CCI (2024)
The most significant recent decision is Amazon.com NV Investment Holdings LLC v. Competition Commission of India, arising from Amazon's 2019 investment in Future Coupons Private Limited (FCPL). Amazon had notified the transaction to the CCI and obtained approval in November 2019. In December 2021, however, the CCI kept that approval in abeyance, directed Amazon to file a fresh notice, and imposed a penalty of Rs 202 crore under Sections 43A, 44 and 45, holding that Amazon had suppressed material information by characterising the deal as an investment in FCPL's gift-card and loyalty business while internally treating it as a strategic route to influence over Future Retail and India's offline retail market.
In 2024 the Supreme Court set aside both the CCI's order and the National Company Law Appellate Tribunal's affirmation of it. The Court drew a sharp distinction between the different default provisions. Section 43A, it held, is triggered by the specific default of failing to file a notice at all; it cannot be invoked where a notice was in fact filed, reviewed by the CCI and approved before the combination took effect, merely because the Commission later disagrees with how the disclosed material was characterised. Suppression of information, if any, engages other provisions (such as Sections 44 and 45), but does not retrospectively convert a filed-and-approved combination into a non-notified one for Section 43A purposes.
The decision is doubly important. Substantively, it confines Section 43A to genuine non-filing and clarifies that the gun-jumping penalty is not a roving sanction for inadequate disclosure. Procedurally, the Court stressed that regulatory fairness and predictability are essential to investor confidence — the CCI cannot reopen a cleared combination years later on a recharacterisation of facts that were before it at the time of approval. For aspirants, Amazon is the counterpoint to Thomas Cook: together they map the boundary between a real timing breach (penalised) and a disclosure dispute over a duly filed and approved deal (not a Section 43A breach).
Section 6(4)-(5): the Green Channel route
To balance suspensory control against the burden it places on plainly harmless deals, the regime offers a Green Channel. Introduced administratively in 2019 and given statutory footing by the 2023 amendment through new Section 6(4) and 6(5), the Green Channel permits deemed approval upon filing for combinations where there is no horizontal overlap, no vertical relationship and no complementary business activity between the parties (and their groups). In other words, where the parties operate in entirely unrelated markets, the transaction is presumptively incapable of causing AAEC, and clearance is automatic the moment a properly completed notice is filed.
The Green Channel materially shortens deal timelines for conglomerate-style acquisitions, but it carries a sharp risk: if the parties wrongly self-assess and there is in fact an overlap or vertical link, the deemed approval is void ab initio and the transaction is treated as never having been validly notified — exposing the parties to gun-jumping penalties. The route therefore rewards accurate self-classification and punishes optimistic mischaracterisation, dovetailing with the composite-transaction and disclosure doctrines discussed above.
The Green Channel also illustrates the statute's underlying economic theory: the categories of horizontal, vertical and complementary relationships track the three principal theories of merger harm — unilateral and coordinated effects in horizontal mergers, foreclosure in vertical mergers, and portfolio effects in conglomerate mergers. Where none of these channels of harm exists, the law sees no reason to wait. Readers should connect this to the broader treatment of dominance, since a merger that creates or strengthens a dominant position is precisely the structural concern combination control exists to catch.
How the CCI reviews a combination
Once a notice is filed under Section 6(2), the CCI's review proceeds in phases. In Phase I the Commission forms a prima facie opinion under Section 29(1) on whether the combination is likely to cause AAEC. If it has no such concern, it approves the combination — the vast majority of filings clear at this stage, often through the Green Channel or a swift Phase I order. If the CCI does form a prima facie view that AAEC is likely, it issues a show-cause notice and the matter moves to Phase II, a detailed investigation involving publication of details of the combination, invitation of objections from the public and affected parties, and a fuller assessment under Section 29.
At the conclusion of review the CCI may, under Section 31, (a) approve the combination if it will not cause AAEC; (b) direct that it shall not take effect if it will cause AAEC; or (c) approve it subject to modifications — structural remedies such as divestiture of assets, or behavioural remedies such as commitments on pricing, access or conduct. The conditional-approval power is heavily used: in Jet Airways–Etihad the CCI cleared the stake acquisition after analysing overlapping origin-and-destination routes and satisfying itself, against the Section 20(4) factors, that the combination would not appreciably harm competition, while a dissenting member would have scrutinised the deal more strictly. Conditional clearances let the CCI preserve the efficiencies of a merger while surgically removing the specific competitive harm.
The 2023 amendment also introduced expedited timelines and a faster framework for forming the prima facie opinion, reflecting a policy choice to make Indian merger control quicker and more predictable — the very value the Supreme Court emphasised in Amazon.
Consequences of contravention and appeal
The consequences of breaching the combination regime are graduated. Section 43A penalises failure to give notice / gun-jumping, with a penalty cap pegged to a percentage of the combination's turnover or assets. Section 44 penalises the making of false statements or omission to state material particulars in a combination notice. Section 45 deals more generally with penalties for furnishing false information or suppressing material facts before the Commission. And Section 6(1) renders a prohibited combination void as a matter of substantive law. The CCI may also, under Section 31, direct unwinding or modification of a combination that has been carried into effect in contravention of an order.
Appeals lie to the National Company Law Appellate Tribunal (NCLAT), which replaced the erstwhile Competition Appellate Tribunal (COMPAT), and thereafter to the Supreme Court under Section 53T. This appellate chain is why the leading combination authorities — Thomas Cook, SCM Soilfert and Amazon — are Supreme Court decisions: each travelled from the CCI through the tribunal to the apex court. For a structured overview of how these enforcement and appellate institutions fit together, see our introduction to the Act and the broader Competition Act notes hub.
Exam strategy and common traps
Three traps recur in judiciary and CLAT-PG questions. First, candidates confuse the size filter (Section 5) with the effect filter (Section 6). Always separate them: a deal must first cross Section 5 thresholds (or the deal value threshold) to be a "combination" at all; only then does the AAEC analysis under Section 6, measured against Section 20(4) factors, arise. A harmless mega-merger is still notifiable; a competitively dangerous small deal is not (subject to the DVT).
Second, candidates misstate the gun-jumping rule. After Thomas Cook and SCM Soilfert, the standstill is a timing obligation: consummating any interdependent limb of a composite transaction before clearance is a breach even if fully disclosed. But after Amazon, Section 43A is reserved for genuine non-filing — a filed-and-approved deal cannot be retrospectively penalised under 43A merely for alleged mischaracterisation. State both propositions to show command of the boundary.
Third, candidates forget the live numbers. Cite the revised 2024 thresholds (Rs 2,500 crore / Rs 7,500 crore at enterprise level; Rs 10,000 crore / Rs 30,000 crore at group level), the deal value threshold of Rs 2,000 crore with substantial Indian operations, and the de minimis target ceilings. Pair the doctrine with the policy rationale — preventive structural control, the killer-acquisition problem, and the efficiency-versus-concentration trade-off — and the answer will read like a complete account of the regime.
Frequently asked questions
What is the difference between Section 5 and Section 6 of the Competition Act?
Section 5 defines what a "combination" is and supplies the size thresholds (assets, turnover and the deal value threshold) that determine whether a transaction is notifiable at all. Section 6 contains the substantive prohibition — a combination causing or likely to cause an appreciable adverse effect on competition is void — and the procedural machinery of mandatory notice (Section 6(2)) and standstill (Section 6(2A)). In short, Section 5 is the size filter and Section 6 is the effect filter and the process.
What are the current combination thresholds under Section 5?
Following the March 2024 revision, the enterprise-level thresholds are combined assets in India exceeding Rs 2,500 crore or turnover exceeding Rs 7,500 crore (with worldwide tests of USD 1.25 billion in assets or USD 3.75 billion in turnover, subject to India minimums of Rs 1,250 crore and Rs 3,750 crore respectively). At group level the figures are Rs 10,000 crore in assets or Rs 30,000 crore in turnover, with worldwide tests of USD 5 billion and USD 15 billion. Either the asset limb or the turnover limb being crossed is sufficient.
What is the deal value threshold introduced in 2023?
The Competition (Amendment) Act, 2023 added a deal value threshold to Section 5 to capture "killer acquisitions" in digital markets. A transaction is notifiable, irrespective of the asset and turnover thresholds, if its value exceeds Rs 2,000 crore and the target has substantial business operations in India (measured by Indian users, subscribers, gross merchandise value and similar metrics under the Combination Regulations). The merger-control provisions including the DVT were notified with effect from September 2024.
What is "gun-jumping" and how was it treated in Thomas Cook and SCM Soilfert?
Gun-jumping is completing or partially completing a notifiable combination before the CCI clears it, or failing to notify at all, in breach of the standstill obligation. In Thomas Cook (India) Ltd. v. CCI and SCM Soilfert Ltd. v. CCI (Supreme Court, 17 August 2018), the acquirers made on-market share purchases before notifying. The Court upheld the CCI's penalties under Section 43A, holding that interdependent steps form a single composite transaction that cannot be consummated piecemeal, and that full disclosure after the fact does not cure a timing breach.
What did the Supreme Court decide in the Amazon-Future Coupons case?
In Amazon.com NV Investment Holdings LLC v. CCI (2024), the Supreme Court set aside the CCI's Rs 202 crore penalty (and the NCLAT order affirming it) relating to Amazon's 2019 investment in Future Coupons. The Court held that Section 43A is triggered only by failure to file a notice; where a notice was filed, reviewed and approved before the combination took effect, Section 43A cannot be invoked merely because the CCI later disagreed with how the disclosed material was characterised. The judgment also stressed regulatory fairness and predictability for investor confidence.
What is the Green Channel route under Section 6(4)?
The Green Channel, introduced in 2019 and codified by the 2023 amendment in Sections 6(4) and 6(5), allows deemed approval immediately upon filing for combinations where the parties (and their groups) have no horizontal overlap, no vertical relationship and no complementary business activity — meaning the deal is presumptively incapable of causing AAEC. The risk is that if the self-assessment is wrong and an overlap exists, the deemed approval is void from the outset, exposing the parties to gun-jumping penalties.
