An intermediary is a person who, on behalf of another, receives, stores or transmits an electronic record, or provides any service with respect to that record. Network service providers, search engines, online marketplaces and social media platforms are intermediaries.
An intermediary is not liable for third-party information made available or hosted by it, provided three conditions are satisfied. First, its function must be limited to providing access to a communication system over which the information is transmitted, stored or hosted. Second, it must not initiate the transmission, select its receiver, or select or modify the information transmitted. Third, it must observe due diligence and such guidelines as the Government may prescribe.
The exemption is lost in two situations: where the intermediary has conspired, abetted, aided or induced the unlawful act, whether by threats, promise or otherwise; and where, upon receiving actual knowledge that a court order or a notification by the appropriate Government agency requires it to remove or disable access to material being used to commit an unlawful act, it fails expeditiously to do so.
The expression "actual knowledge" has been read narrowly. A private complaint by a member of the public, however emphatic, does not amount to actual knowledge; the intermediary must receive a court order or an authorised government notification. The reason given is that an intermediary faced with lakhs of private demands, and threatened with liability for refusing any of them, will simply remove whatever is complained of, and lawful speech will disappear along with the unlawful.
Automatic removal by an algorithm the intermediary has itself deployed does not amount to selection or modification of content by the intermediary for these purposes.
