Correct Option
Statement 1 is correct. As per Article 94(c) of the Constitution of India, when a resolution for the removal of the Speaker of the Lok Sabha is under consideration, the Speaker shall not preside at that sitting of the House. In such a scenario, the Deputy Speaker or any other person determined by the House presides over the proceedings.
Incorrect Options
Statement 2 is incorrect. During the consideration of a resolution for their removal, the Speaker retains the right to speak in, and otherwise take part in the proceedings of, the House. The restriction is specifically on presiding, not on general participation in the debate.
Statement 3 is incorrect. The Speaker is entitled to vote on the resolution in the first instance, just like any other member of the House. The provision for a casting vote, exercisable only in the event of a tie, applies when the Speaker is presiding. Since the Speaker does not preside during the removal proceedings, they exercise their right to vote as an ordinary member.
