Abuse of Dominance and Vertical Restraints Compared

The same commercial arrangement, an exclusivity, a tie, a refusal to supply, a price condition imposed on a dealer, may be examined under Section 3(4) as a vertical restraint or under Section 4 as an abuse. Which provision applies depends on two things: whether there is an agreement, and whether the enterprise is dominant. The consequences differ substantially, in what must be proved, in who is liable and in what defences are available, so the classification is the first step and not a formality.

1. The Comparison

Basis	Vertical restraint, Section 3(4)	Abuse of dominance, Section 4
Requires an agreement	Yes, between parties at different levels in different markets	No; unilateral conduct is enough
Requires dominance	No, though market power is decisive in practice	Yes, established in a defined relevant market through Section 19(4)
What must be proved	That the agreement causes or is likely to cause an appreciable adverse effect, using the Section 19(3) factors	Dominance, and that the conduct falls within a clause of Section 4(2)
Appreciable adverse effect	An ingredient	Not an ingredient
Who is liable	Both parties to the agreement, including the distributor	Only the dominant enterprise
Exemptions	Section 3(5) saves reasonable conditions protecting intellectual property, and agreements relating exclusively to exports	No corresponding saving
Consequence	The agreement is void under Section 3(2); orders and penalties follow	No voidness provision; orders and penalties under Section 27, and division under Section 28

2. The Practical Differences

Proof. Under Section 3(4) the Commission must establish the effect; under Section 4 it must establish dominance. Which is easier depends on the facts, and the informant will ordinarily plead both.
Exposure of the counterparty. A distributor that accepted an exclusivity is a party to the agreement and is exposed under Section 3(4); it is not liable under Section 4, which reaches only the dominant enterprise. This matters to a distributor asked to sign restrictive terms, and it is a reason such a party may itself approach the Commission.
Intellectual property. Section 3(5) saves reasonable conditions necessary to protect the listed rights, and there is no equivalent in Section 4. An enterprise relying on its intellectual property to justify a restriction is in a materially weaker position if it is dominant.
Voidness. Section 3(2) makes a contravening agreement void, so it cannot be enforced between the parties. Section 4 contains no such provision; the conduct is prohibited and penalised, but the contract is not struck down by the section.
Justification. Under Section 3(4) the beneficial factors in Section 19(3) are weighed as part of a single conclusion. Under Section 4 there is no statutory efficiency provision, and justification enters through the assessment of whether conditions are unfair and whether the conduct has a legitimate business explanation, with the proviso to clause (a) expressly permitting terms adopted to meet the competition.

3. When Both Apply

Where a dominant supplier imposes restrictions by agreement on its distributors, both provisions are engaged and the Commission commonly finds contraventions of each. Shri Shamsher Kataria v. Honda Siel Cars India Ltd., decided by the Commission in 2014, is the standard illustration: arrangements with dealers restricting the supply of genuine spare parts and diagnostic tools were held to contravene Section 3(4) as exclusive supply and exclusive distribution agreements and refusals to deal, and the same conduct was held to be an abuse under Section 4 through denial of market access and the use of a position in the primary market to protect the aftermarket.

⚠ How to structure an answer where both are pleaded

Define the relevant market first, because both provisions depend on it. Then take Section 4, since if dominance is established the analysis is shorter: the conduct need only fall within a clause, and no appreciable adverse effect need be proved. Then take Section 3(4) in the alternative, on the footing that if dominance is not established the arrangement must still be assessed by its effect. Deal with the justification once, since the same commercial explanation answers both, and note expressly that the intellectual property saving is available only under Section 3.
