The Competition Act is the law that keeps markets honest. It stops rivals from secretly fixing prices, stops dominant companies from crushing smaller competitors, and reviews big mergers before they can concentrate too much power in too few hands. For two decades it has shaped how businesses behave — and a major 2023 amendment, phased in through 2024, modernised it for the digital age, capturing the kind of "big tech" deals the old rules missed and giving companies a faster way to settle investigations. This guide explains how the Act works, what it prohibits, the regulator behind it, and the changes every business now has to plan around.
Quick answer: The Competition Act, 2002 prohibits anti-competitive agreements (Section 3), abuse of a dominant position (Section 4), and regulates combinations — mergers and acquisitions (Sections 5–6) — through the Competition Commission of India (CCI). The Competition (Amendment) Act, 2023 (phased in through 2024) added a deal-value threshold (deals over ₹2,000 crore with substantial Indian operations need CCI approval), a settlement and commitment mechanism, penalties indexed to global turnover, a 3-year limitation to file information, and faster merger reviews. Appeals go to the NCLAT.
Why competition law exists
Markets work best when firms compete on price, quality, and innovation. They fail consumers when competitors collude to fix prices, when a dominant firm abuses its power to exclude rivals, or when a merger removes a competitor and concentrates the market. The Competition Act, 2002 — which replaced the older MRTP Act — exists to prevent practices that have an "appreciable adverse effect on competition" (AAEC) in India, protecting both consumer welfare and the freedom of businesses to compete fairly.
The three pillars of the Act
The Act regulates three kinds of conduct:
- Anti-competitive agreements between enterprises (Section 3).
- Abuse of a dominant position by a powerful enterprise (Section 4).
- Combinations — mergers, acquisitions, and amalgamations above certain thresholds (Sections 5–6).
The CCI enforces all three, assisted by a Director General (DG) who investigates.
Anti-competitive agreements (Section 3)
Section 3 prohibits agreements that cause or are likely to cause an AAEC. It distinguishes two types:
- Horizontal agreements (between competitors at the same level — cartels, bid-rigging, price-fixing, output limits, market sharing) are presumed to have an AAEC. These are the most serious violations.
- Vertical agreements (between firms at different levels — supplier and distributor, e.g., resale price maintenance, exclusive supply/distribution, tie-ins) are judged by the "rule of reason" — examined for their actual competitive effect.
The 2023 amendment also brought "hub-and-spoke" arrangements (where a common intermediary coordinates a cartel between competitors) clearly within the presumptive rule.
Abuse of dominant position (Section 4)
Being dominant isn't illegal — abusing dominance is. Section 4 prohibits a dominant enterprise from, for example, imposing unfair or discriminatory prices or conditions, limiting production or technical development, denying market access, or using dominance in one market to enter another. The CCI first defines the relevant market, assesses whether the enterprise is dominant in it, and then examines whether its conduct is abusive.
Regulation of combinations (Sections 5–6)
Large mergers and acquisitions must be notified to and approved by the CCI before completion, if they cross prescribed thresholds. Historically these thresholds were based on the parties' assets and turnover. The CCI reviews whether the combination would cause an AAEC and can approve it, approve it with modifications, or block it. The 2023 amendment significantly changed this regime (below).
The Competition Commission of India
The CCI is the statutory regulator that enforces the Act. It can inquire into violations (on its own, on a reference, or on information filed by any person), direct the Director General to investigate, pass cease-and-desist orders, impose penalties, and review combinations. Its orders are appealable to the National Company Law Appellate Tribunal (NCLAT) and onward to the Supreme Court.
The Competition (Amendment) Act, 2023
This is the biggest overhaul since 2002, designed to modernise the law and align it with global practice. It received assent on 11 April 2023 and was implemented in phases through 2024. The key changes:
- Deal-value threshold (DVT): in addition to the asset/turnover tests, any transaction with a deal value above ₹2,000 crore now requires CCI approval if the target has "substantial business operations in India." This was introduced to capture acquisitions of asset-light digital companies — the "killer acquisitions" by big tech that the old thresholds missed. It came into effect in September 2024.
- Settlement and commitment framework: firms under investigation for abuse of dominance or vertical agreements can now apply to settle (after the DG's report) or offer commitments (after the prima facie order, before the DG report) to close cases faster — not available for cartels. The CCI's decisions on these are not appealable.
- Penalties on global turnover: penalties for anti-competitive conduct can now be calculated with reference to global turnover, a major increase in exposure for diversified and multinational firms.
- Leniency Plus: a cartel member already cooperating can earn additional penalty reductions by disclosing a separate cartel.
- 3-year limitation: information/references on contraventions must generally be filed within three years (with the CCI able to condone delay).
- Faster merger review: the overall review timeline was shortened (toward 150 days), with a quick prima-facie opinion window, and on-market/open-offer purchases allowed before approval (without exercising control until cleared).
- 25% pre-deposit to appeal a penalty to the NCLAT.
The practical upshot: more deals are caught, reviews are faster, penalties can be far larger, and companies have a new route to settle.
Penalties and appeals
The CCI can impose substantial monetary penalties (now referable to global turnover for anti-competitive conduct), order enterprises to cease and desist, modify agreements, and direct divestiture or behavioural remedies in combinations. For cartels, penalties can be levied on each participant for each year of the agreement's continuance. Appeals lie to the NCLAT (with the 25% pre-deposit), and then to the Supreme Court.
Worked example
A large digital platform agrees to acquire a fast-growing app for ₹2,500 crore. The app has modest assets and turnover, so under the old asset/turnover tests the deal might have escaped CCI scrutiny — as some high-value digital deals once did. Under the 2023 deal-value threshold, because the value exceeds ₹2,000 crore and the target has substantial Indian operations, the acquirer must notify the CCI and obtain approval before completing. Separately, if that platform were later found to have abused its dominance, it could apply under the new settlement/commitment framework to resolve the case faster rather than litigate to the end — though it would face penalties potentially keyed to global turnover.
Common mistakes
- Assuming a low-turnover deal is exempt. The deal-value threshold now catches high-value, asset-light deals.
- Treating cartels as settleable. Settlement/commitment doesn't apply to cartels — leniency does.
- Underestimating penalty exposure. Penalties can now reference global turnover.
- Missing the 3-year limitation to file information.
- Closing a notifiable deal before CCI approval, risking gun-jumping penalties.
Key takeaways
- The Act prohibits anti-competitive agreements (S.3), abuse of dominance (S.4), and regulates combinations (S.5–6).
- Horizontal cartels are presumed harmful; vertical agreements use the rule of reason.
- The CCI enforces the law; appeals go to the NCLAT and Supreme Court.
- The 2023 amendment added a ₹2,000-crore deal-value threshold, settlement/commitment, and global-turnover penalties.
- Merger reviews are now faster, and more deals are notifiable.
- A 3-year limitation applies to filing information on contraventions.
