IT Act and the Consumer Protection Act: The E-Commerce Interface

An online purchase is governed by two regimes at once: the IT Act makes the contract valid and defines when the platform is a shielded intermediary, and consumer law imposes the duties the platform owes buyers in its own right. The crucial point is that the Section 79 shield never reaches those consumer duties. Topic 89 built the e-commerce framework; this note, as asked, maps the interface.

1. Which Law Governs What

Figure 1: The layers of an online sale

• The contract. The IT Act validates the electronic transaction: s.10A for the contract formed electronically, and ss.11 to 13 for attribution, acknowledgment and dispatch of the communications (Topics 45, 47)
• The platform's intermediary status. The IT Act again: a marketplace is an intermediary claiming s.79 for third-party listings while passive, a shield lost on active participation under the Louboutin line and the 2021 Rules (Topic 89)
• Consumer rights and unfair practices. The Consumer Protection Act 2019 and the Consumer Protection (E-Commerce) Rules 2020: disclosure of seller and country-of-origin details, no unfair trade practice, no fake reviews, a grievance officer, and product and service liability, the platform's own duties.
• The divide. s.79 shields liability for third-party information only; it does not answer a consumer claim for the platform's own defaults, deficient service, unfair practice, breached disclosure, the point courts have repeatedly enforced.

2. How the Regimes Fit

• Marketplace against inventory. Consumer law distinguishes the marketplace entity, carrying disclosure and grievance duties toward buyers and brand owners, from the inventory entity, carrying full seller and product liability; the IT Act's intermediary analysis maps onto the marketplace model (Topic 89)
• Two liability streams. The same transaction can run the IT Act stream, intermediary liability for third-party listings governed by s.79, and the consumer-law stream, the platform's own statutory duties, neither answering for the other.
• Consumer jurisdiction. The Consumer Protection Act lets the consumer sue where the complainant resides or works, a pro-consumer venue that cannot be displaced by an exclusive-jurisdiction clause in the platform's terms (Topic 89)
• The practical lesson. A platform defending a dispute must ask which stream: an infringing or defamatory listing engages s.79 and its conditions, while a deficient-service or unfair-practice claim engages consumer law directly, where s.79 is no defence.

3. Frequently Asked Questions

How do the IT Act and consumer law divide an online sale?

The IT Act validates the electronic contract under Section 10A and defines the platform's intermediary status under Section 79, shielding it for third-party listings while it stays passive. The Consumer Protection Act 2019 and the Consumer Protection (E-Commerce) Rules 2020 impose the platform's own duties toward buyers, disclosure of seller and origin details, no unfair trade practices, a grievance officer, and marketplace or inventory liability. The decisive point is that Section 79 shields only third-party-information liability and never answers a consumer claim for the platform's own defaults, and the consumer may sue where they reside regardless of the platform's jurisdiction clause.
