The correct statement is that the Speaker of the Lok Sabha shall not preside over the proceedings when a resolution for their removal is under consideration. This is to maintain impartiality and the integrity of the office, ensuring that the Speaker does not exert influence during a discussion that directly affects their position. However, the Speaker retains the right to speak and can vote in the case of a tie, thus statements 2 and 3 are incorrect. This reflects the principles of parliamentary democracy, where the Speaker's neutrality is crucial for fair proceedings, which is an important aspect in the context of UPSC examination preparations focusing on constitutional norms.
