NRS 353.235
Appropriation and authorization by Legislature.
1.
Every appropriation in addition to that provided for in the proposed budget must be embodied in a separate bill and must be limited to some single work, object or purpose stated in the bill.2.
A supplementary appropriation is not valid if it exceeds the amount in the State Treasury available for the appropriation, unless the Legislature making the appropriation provides the necessary revenue to pay the appropriation by a tax, direct or indirect, to be laid and collected as directed by the Legislature. The tax must not exceed the rates permitted under the Constitution of the State of Nevada. This provision does not apply to appropriations to suppress insurrections, defend the State, or assist in defending the United States in time of war.3.
An appropriation of money must not be made or a level of salary or other expenditure established which is contingent upon the attainment, during the biennium in which the money is to be expended or the salary or level of expenditure is to be effective, of a specified balance in the State General Fund.4.
The revenues and other resources of any fund are subject to legislative authorization or appropriation and legislative review for each fiscal period except where that procedure conflicts with the Constitution or an express provision of statute.
