Union Government
(1) The Speaker (or Deputy Speaker) shall not preside over a sitting while a resolution for their own removal is under consideration, even if present. (2) The Speaker may speak and take part in such proceedings and is entitled to vote in the first instance (though not in the case of an equality of votes).
This mirrors Article 92 for the Lok Sabha's Speaker: they cannot preside over the debate on their own removal, though they retain a right to speak and, notably, a limited voting right that the Rajya Sabha's Chairman does not have in the equivalent situation.
If the Lok Sabha debates removing its Speaker, someone else (typically the Deputy Speaker) presides over that sitting while the Speaker can participate in the debate and cast a first-instance vote on the resolution.
