Carr v. Frohmiller
In Carr v. Frohmiller, 47 Ariz. 430, 56 P.2d 644 (1936), the legislature, through a general appropriations bill, limited the expenditure of funds that had previously been "levied and collected" for a specific purpose. Carr, 47 Ariz. at 441-42, 56 P.2d at 649.
The Carr court found "real, serious fundamental objection to the Legislature's levying and collecting taxes for a specific object and purpose and then prohibiting its expenditure for that purpose and letting it revert to the general fund." Id. at 442, 56 P.2d at 649.
