Money Bills: why the Rajya Sabha can only recommend, and what happens after fourteen days
Background
A Money Bill may be introduced only in the Lok Sabha, on the recommendation of the President.
After the Lok Sabha passes it, the Rajya Sabha must return it within fourteen days of receipt, with or without recommendations, under Article 109.
The Lok Sabha may accept or reject any of the recommendations; if it accepts none, the Bill is deemed passed in the form the Lok Sabha passed it.
If the Rajya Sabha does not return it in fourteen days, it is deemed passed by both Houses in the form the Lok Sabha passed it.
The Speaker certifies a Bill as a Money Bill under Article 110(3), and the Speaker's decision is final.
There is no provision for a joint sitting on a Money Bill.
In plain words
Money Bill Money Bill — A Bill containing only matters such as taxation and Consolidated Fund spending listed in Article 110.
Financial Bill Financial Bill — A Bill with some money provisions plus other matters; unlike a Money Bill it needs both Houses.
