A clean way to work through this fact pattern is to isolate each of the three prongs of the proportionality test separately and check whether the influencer's conduct clears or fails each one.
Legality: is there an actual law that could apply. Yes. The Bharatiya Nyaya Sanhita's obscenity provisions and Section 67 of the Information Technology Act both criminalise obscene material, including material transmitted or published online, so the first prong is satisfied regardless of the final outcome.
Legitimate aim: does the restriction serve a purpose recognised under Article 19(2). Decency and morality are expressly named as grounds in Article 19(2), and preventing obscene content from reaching the public, especially minors, is a legitimate aim under that head. This prong is also satisfied.
Proportionality: is criminal prosecution, as opposed to a lesser response such as a takedown or warning, a proportionate way to deal with this speech. This is the prong that actually decides the case. In favour of the influencer: the audience joined voluntarily, there was no display of an actual sexual act, and explicit language alone has repeatedly been held short of obscenity, as in College Romance, where the Delhi High Court found vulgar dialogue in a mature, consensual context did not meet the deprave and corrupt standard. Against the influencer: a live stream reaches a broad, less controlled audience that may include minors, multiple States have registered FIRs suggesting a widespread public harm perception, and the Supreme Court in the Ranveer Allahbadia matter specifically flagged that mass-reach influencers carry a higher responsibility than a scripted, age-gated web series, and should not automatically get the benefit of the College Romance quashing logic.
Balancing these factors, the correct legal position is that the speech remains protected under Article 19(1)(a) as long as it stays at the level of vulgar or crude language without becoming obscene in the deprave-and-corrupt sense, but it loses protection, and the FIRs may validly proceed, once the content crosses the obscenity threshold, with the live, mass-audience nature of the broadcast making courts less willing to quash the proceedings outright.
