The Pro-Tem Speaker of the Lok Sabha is a temporary position appointed for a specific period until a regular Speaker is elected. The role of the Pro-Tem Speaker includes several functions.
Firstly, option 1 states that the Pro-Tem Speaker conducts the proceedings of the House in the absence of the Speaker. This means that when the regular Speaker is absent or unable to fulfill their duties, the Pro-Tem Speaker takes charge and ensures the smooth running of the proceedings.
Option 2 suggests that the Pro-Tem Speaker checks the election certificates of the members of the House. However, this is not a function of the Pro-Tem Speaker. It is the responsibility of the Election Commission to verify the election certificates of the members.
Option 3, which is the correct answer, states that the Pro-Tem Speaker swears in the members of the House and holds the charge until a regular Speaker is elected. When a new Lok Sabha is formed after elections, the Pro-Tem Speaker administers the oath or affirmation to the newly elected members before the Speaker is elected.
Option 4 is incorrect as the Pro-Tem Speaker does not have the power to give assent to bills passed by the House. The assent to bills is the prerogative
