The concept of a joint sitting of both Houses of Parliament is addressed under Article 108 of the Indian Constitution. When a legislative deadlock occurs due to the inability of the two Houses to agree on a Bill, the Constitution provides a mechanism to resolve it through a joint sitting.
In this context, if a Bill is passed by one House and then rejected by the other, or if no resolution is reached even after amendments, the President is empowered to summon a joint sitting of both Houses to deliberate and vote on the Bill. This provision ensures legislative efficiency by enabling the resolution of conflicts between the Lok Sabha and the Rajya Sabha.
In conclusion, the correct answer to the query regarding who calls the joint sitting of both Houses of Parliament when there is disagreement on a Bill is: President.
