State Government
(1) There is freedom of speech in every State's Legislature, subject to the Constitution and its own rules. (2) No member is liable in court for anything said or voted in the Legislature or a committee, nor is anyone liable for authorised publication of reports/proceedings. (3) Other privileges are as the state Legislature defines by law, and until then, as they stood immediately before the relevant 44th Amendment provision came into force. (4) These provisions extend to non-members with a constitutional right to speak in the Legislature.
This mirrors Article 105 at the state level: MLAs and MLCs have the same kind of strong legal protection for what they say and how they vote inside the state Legislature, letting them debate candidly without fear of being sued or prosecuted over their in-House speech specifically.
An MLA who makes serious allegations during a state Assembly debate generally cannot be sued for defamation over those specific in-House remarks, thanks to this freedom-of-speech protection - though the same statement made outside the Assembly would not enjoy this immunity.
