Dark Patterns on E-Commerce Platforms: Unfair Practices, Consent and Platform Duties

The dark pattern is wherever a screen sells, but its natural habitat is the e-commerce platform, where design decides what millions notice, pay and agree to. This note puts the pieces together for that habitat: how the patterns map onto unfair trade practices and the consent rules of the E-Commerce framework, what duties the platform now carries across its instruments, and how enforcement and compliance work in practice.

1. The Pattern as Unfair Trade Practice

The 2023 Guidelines' mapping clause does the doctrinal work: every dark pattern amounts to a misleading advertisement, an unfair trade practice or a violation of consumer rights. On a platform the correspondences are concrete. False urgency and bait and switch are the bargain-price and false-representation clauses of Section 2(47) in interface form, and misleading advertisements under Section 2(28) where a listing carries them. Drip pricing offends the materially-misleading-price clause and the E-Commerce Rules' demand for total, single-figure prices with break-up. Disguised advertisements violate the 2022 Guidelines' disclosure rules and the fake-review prohibitions of Rules 6 and 7. Forced action, where it compels disclosure of personal information, meets the 2019 addition to Section 2(47) on disclosure of personal information given in confidence. The practical consequence: the complainant and the regulator never need a new cause of action, the pattern is pleaded as the statutory wrong it amounts to, with the design evidence proving it.

2. The Consent Architecture

What the money patterns really attack is consent, and the e-commerce framework defends it at three points. Formation: the E-Commerce Rules require consent for a purchase to be recorded only by explicit and affirmative action, never pre-ticked boxes or defaults, which condemns basket sneaking at its root: the add-on the consumer did not affirmatively choose is a charge without consent. Continuation: the subscription trap and SaaS billing convert one consent into perpetual payment; the Rules' fair-dealing and refund duties, the Guidelines' prohibition, and the RBI's e-mandate discipline for recurring charges (notification before debit, easy withdrawal) together require that continuing payment rest on continuing, revocable consent, cancellation as easy as subscription. Data: forced sharing of personal information as the price of a purchase, and the use of consumer data to push unrelated sales, are met by the unfair-practice clause, the platforms' confidentiality duties, and the 2026 E-Commerce Amendment's bar on using consumer data for indirect sales without explicit consent, with the data-protection statute's consent standards operating alongside.

3. The Platform's Stacked Duties

• Under the E-Commerce Rules (2020): fair dealing, no price manipulation, total prices, affirmative consent, symmetric cancellation charges, truthful listings and the no-refusal refund rule, the baseline the patterns breach.
• Under the 2023 Guidelines: the flat prohibition, no person, including any platform, shall engage in any dark pattern practice, with the thirteen-species annexure as the audit checklist.
• Under the advertising instruments: the 2022 Guidelines on bait, free claims and disclosure govern the content the interface carries; disguised advertisements and undisclosed influencer promotion are condemned on both sides.
• Under the 2026 Amendment (from 1 January 2027): yearly dark-pattern self-audits with the compliance certificate prominently displayed; the thirty-day prior-price benchmark that kills the fake discount; sponsored results separated from organic; manipulative search practices barred; bundled fees for unrelated services restricted.
• The design brief in reverse: neutral defaults, complete first-screen prices, symmetric join-and-leave friction, labelled advertising, honest scarcity, and documented audits, compliance is an interface specification.

4. Enforcement in Practice

• The CCPA: advisories to major platforms directing self-audit and removal of identified patterns; notices and investigations on specific flows (charges added without consent, cancellation obstruction); Section 21 penalties where the pattern is a misleading advertisement; class-protection orders where it is an unfair trade practice.
• The Commissions: the individual consumer's complaint, the unconsented add-on refunded, the trapped subscription cancelled with compensation, pleaded on the mapped wrong with screenshots and screen recordings as the record.
• The platform's exposure beyond the consumer: repeated patterns invite the repeat-contravention penalty scale, reputational orders (corrective disclosure), and, once the audit duty operates, the separate consequence of a false compliance certificate.
• The evidentiary habit: capture the flow end to end, first price to final charge, the consent screens, the cancellation path, because the pattern is proved by replaying the design, not by debating intentions.
