Mode of exercising Federal Legislative power: money bills
Section 59(2) · 1999 Constitution (2004 edition)
What Constitution says
(2) Where a bill to which this section applies is passed by one of the Houses of the National Assembly but is not passed by the other House within a period of two months from the commencement of a financial year, the President of the Senate shall within fourteen days thereafter arrange for and convene a meeting of the joint finance committee to examine the bill with a view to resolving the differences between the two Houses.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
