Idaho Constitution Art. VII, § 15. Legislature to provide system of county finance

The legislature shall provide by law, such a system of county finance, as shall cause the business of the several counties to be conducted on a cash basis. It shall also provide that whenever any county shall have any warrants outstanding and unpaid, for the payment of which there are no funds in the county treasury, the county commissioners, in addition to other taxes provided by law, shall levy a special tax, not to exceed ten mills on the dollar, of taxable property, as shown by the last preceding assessment, for the creation of a special fund for the redemption of said warrants; and after the levy of such special tax, all warrants issued before such levy, shall be paid exclusively out of said fund. All moneys in the county treasury at the end of each fiscal year, not needed for current expenses, shall be transferred to said redemption fund.
