Often, yes. A seller disappearing from a marketplace is not the platform's excuse, it is the platform's problem, because the 2020 Rules made the platform the keeper of the seller's identity. This answer is only about the vanished-seller case. Whether to sue both together and how to plead the platform's own conduct is in the marketplace and seller together answer, and the general law on wrong or defective deliveries is in our note on platform liability for a wrong product. The first thing to do today is to screenshot the seller's page and the order, because listings vanish too.
What was the platform supposed to know about the seller?
Everything you now need. Rule 6(4)(a) of the Consumer Protection (E-Commerce) Rules, 2020 requires any seller on a marketplace to have a prior written contract with the platform, and Rule 6(4)(d) requires the seller to provide the platform with its legal name, the principal geographic address of its headquarters and all branches, its website, email, customer care numbers and, where applicable, its GSTIN and PAN. Rule 5(3)(a) requires the marketplace to display seller details to users at the pre-purchase stage, and its proviso is the operative tool: on a request in writing made by a consumer after a purchase, the marketplace shall provide information regarding the seller from which the purchase was made, including the principal geographic address of its headquarters and all branches, the name and details of its website, its email address and any other information necessary for communication with the seller for effective dispute resolution.
Rule 4(4) requires every e-commerce entity to appoint a grievance officer and display the officer's name, contact details and designation, Rule 4(5) requires that officer to acknowledge a complaint within forty-eight hours and redress it within one month, and Rule 5(3)(b) requires a ticket number for every complaint so you can track it. Rule 4(2) requires the platform to display its own legal name and principal address. Rule 8 then provides that the provisions of the Consumer Protection Act, 2019 apply to any violation of the Rules, which is what turns a platform's failure to answer your Rule 5(3)(a) request into a cause of action against the platform itself.
- Write to the platform's grievance officer, citing the proviso to Rule 5(3)(a), requesting the seller's legal name, principal address, all branch addresses, website and email, and stating that the request is for dispute resolution. Note the ticket number.
- Diarise forty-eight hours for the acknowledgment and one month for redressal under Rule 4(5). Silence at either point is a breach you will plead.
- If the platform supplies the details, use them to pursue the seller. Name the platform only where the facts support a claim against it, including a proved breach of its own disclosure duty. Rule 6(4)(d) imposes the information-supply duty on the seller.
- Send a copy of the grievance to the Central Consumer Protection Authority under Section 17 of the Act, and file the consumer complaint at your place of residence under Section 34(2)(d).
When is the platform itself liable for the seller's default?
Start with which kind of platform it is, because Rule 3(1) draws the line. An inventory e-commerce entity, defined in Rule 3(1)(f), owns the stock and sells it directly, so it is the seller and there is no one to vanish. A marketplace e-commerce entity, defined in Rule 3(1)(g), provides the technology platform for buyers and third-party sellers. A marketplace may claim the intermediary exemption under Section 79 of the Information Technology Act, but Rule 5(1) makes that claim conditional on compliance with Section 79(2) and (3) and the intermediary guidelines, and Rule 5(2) requires it to take an undertaking from every seller that listings are accurate. A marketplace that onboarded a seller without the Rule 6(4)(d) particulars, or that cannot produce them now, has a difficult time showing the due diligence the exemption requires.
Section 86 requires a separate analysis. A vanished seller alone does not satisfy the untraceable-manufacturer condition, and a product-liability action requires harm within Section 2(22). It makes a product seller who is not the manufacturer liable in a product liability action where, under clause (d), the product was sold by him and the identity of the product manufacturer is not known, or if known, notice or process cannot be served on him, or he is not subject to Indian law, or an order against him cannot be enforced. The section speaks of the manufacturer, and whether a marketplace that collected your money, controlled the listing and ran the returns process is itself a product seller within Section 2(37) is a question decided on the facts of each transaction. Plead those facts specifically. Plead, too, the platform's own promises, because a guaranteed delivery date, an authenticity badge or a published refund policy in the platform's own name is the platform's conduct and no exemption covers it.
| Who | What you plead | Provision |
|---|---|---|
| The seller, by the legal name and address the platform supplied | Defect, non-delivery or misdescription, and refusal to refund | Sections 2(10), 2(11), 2(47), Rule 6(3) |
| The platform, on its own failures | No seller details on request, no grievance acknowledgment in forty-eight hours, no redressal in a month | Rules 4(5), 5(3)(a) proviso and Rule 8. Rule 6(4)(d) separately governs the seller |
| The platform, as product seller | It marketed the product, held the price, ran the returns, and the manufacturer cannot be served and the statutory product-liability conditions are met | Sections 2(37), 83, 86(d) |
| The platform, on its own promises | The delivery guarantee, the authenticity assurance, the refund policy it published | Section 2(11), Rule 4(3) |
What does the CCPA route add?
A second pressure point, aimed at the practice rather than your refund. Section 17 lets a complaint about violation of consumer rights or unfair trade practices that are prejudicial to consumers as a class be forwarded, in writing or electronically, to the District Collector, the Commissioner of the regional office or the Central Authority. Section 18(2)(a) empowers the Central Authority to inquire into such violations on a complaint, Section 18(2)(b) lets it file complaints before the commissions itself, and Section 20 lets it order reimbursement of the price of recalled goods and discontinuation of unfair practices after investigation. A platform that routinely lets sellers vanish is the kind of pattern this machinery exists for, and a CCPA reference attached to your commission complaint is read.
- Screenshots of the seller's page, the listing and the order, taken with the date visible, before they disappear
- The order confirmation, the invoice and the tax invoice, which may name different entities
- Your written Rule 5(3)(a) request, the ticket number and every reply or the absence of one
- Payment proof showing which entity received the money
- The platform's own published policy on returns, refunds or authenticity, screenshotted
- The CCPA complaint acknowledgment
The mistake I see most is a complaint filed against the app's brand name with the seller shown as unknown. The commission issues notice, nothing is served, and a year passes. Ten minutes on the public company record gives you the platform's registered name and office, and the Rule 5(3)(a) request, sent on day one, either gives you the seller or gives you the platform. Either way the complaint proceeds.
