Who among the following has a right to speak and otherwise take part in proceedings of either house of Parliament and to be a member of any parliamentary committee, but is not entitled to vote?

Under Article 88 of the Indian Constitution, the Attorney General of India has the specific right to speak and participate in the proceedings of either House of Parliament, any joint sitting of the Houses, and any committee of Parliament of which they may be named a member. However, by virtue of this article, they are not entitled to a vote in these proceedings [2]. This constitutional provision also extends to Union Ministers, allowing them to participate in both Houses regardless of which House they belong to, though they can only vote in the House where they hold membership. The Attorney General also enjoys all the parliamentary privileges and immunities available to a Member of Parliament to ensure the effective discharge of their duties [1]. Other officials like the Comptroller and Auditor General or the Chief Election Commissioner do not possess these specific participation rights under Article 88.
