Contingencies Fund (National Assembly)
Section 83(1) · 1999 Constitution (2004 edition)
What Constitution says
(1) The National Assembly may by law make provisions for the establishment of a Contingencies Fund for the Federation and for authorising the President, if satisfied that there has arisen an urgent and unforeseen need for expenditure for which no other provision exists, to make advances from the Fund to meet the need.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
