Karnataka High Court Stays Blocking Order Against Proton Mail, Grants Interim Relief

The Karnataka High Court has intervened to halt the potential blocking of Proton Mail in India, granting the encrypted email service a critical reprieve. A Division Bench, led by the Chief Justice and Justice C.M. Poonacha, issued a stay on March 16, 2026, suspending a previous single-judge order that had mandated the platform's blocking under the IT Act. This order had stemmed from allegations of the platform's misuse. The stay effectively restrains authorities from taking any action to block Proton Mail until at least June 23, 2026, a development highlighted by the Internet Freedom Foundation.

This legal challenge was initiated by Proton AG, the Swiss parent company, which filed a writ appeal against the initial ruling. The case centers on the tension between national security enforcement and the operational viability of privacy-centric technology platforms. Proton Mail, launched in 2014 by scientists, is designed with end-to-end encryption that secures emails on a user's device, making content accessible only to the sender and recipient. The service is part of a broader suite of privacy tools offered by Proton, including a VPN and cloud storage.

The court's interim stay introduces a significant pause in a proceeding that could set a precedent for how India regulates encrypted communication services. The outcome will be closely watched by the global tech privacy community and other platforms offering similar security features. The next hearing is scheduled for June, where the broader legal arguments concerning platform liability, encryption, and state authority under Indian law will be scrutinized, with substantial implications for digital privacy standards and intermediary liability in the country.
