The function of a Protem Speaker is to swear in the newly elected members of the House and hold charge until a regular Speaker is elected. Option 1 is incorrect because conducting the proceedings of the House in the absence of the Speaker is the role of the Deputy Speaker or the Panel of Chairpersons. Option 2 is incorrect because a Protem Speaker does not officiate as Speaker on a regular basis, but rather serves temporarily until a regular Speaker is elected. Option 4 is also incorrect because the scrutinizing of election certificates of members is typically done by the Election Commission or a designated authority, not by the Protem Speaker. It is important to note that the Protem Speaker is appointed before the regular Speaker of the House is elected in order to facilitate the initial proceedings and maintain order until the Speaker is chosen.
