Fees shall be deposited with the state treasurer and shall be credited to the weights and measures inspection fund, which is hereby created and established. Moneys in the weights and measures inspection fund shall be invested as provided in section 67-1210, Idaho Code, and interest earned on investment of idle moneys in the fund shall be paid to the fund. Moneys in the fund shall be used solely for carrying out the provisions of title 71, Idaho Code, and may be expended only pursuant to legislative appropriation.
