The Speaker of the Lok Sabha may be removed from office by

According to Article 94 of the Indian Constitution, the Speaker of the Lok Sabha can be removed from office by a resolution passed by a majority of all the then members of the House [3]. This is commonly referred to as an 'effective majority'. The procedure requires that such a resolution can only be moved after giving at least 14 days' advance notice [3]. While the resolution for removal is under consideration, the Speaker cannot preside over the sitting of the House, although they may be present, participate in proceedings, and vote in the first instance [4]. This specific removal process is distinct from a general no-confidence motion, which is directed against the Council of Ministers rather than a presiding officer [2]. The Speaker remains in office even after the dissolution of the Lok Sabha until the first meeting of the newly elected House [3].
