Can the President call a joint sitting of both Houses to resolve differences over a Bill?
Yes, the President can call a joint sitting of both Houses to resolve differences over a Bill. This is evident from Article 108 (1) which states that "If after a Bill has been passed by one House and transmitted to the other House-". This implies that the two houses have not agreed on the bill, and it needs further discussion and resolution, which would be held during a joint sitting of both Houses.
