§ § 31General appropriation bills; priority, statement of estimated revenue

Sec. 31.
    The general appropriation bills for the succeeding fiscal period covering items set forth in
 the budget shall be passed or rejected in either house of the legislature before that house passes
 any appropriation bill for items not in the budget except bills supplementing appropriations for
 the current fiscal year's operation. Any bill requiring an appropriation to carry out its purpose
 shall be considered an appropriation bill. One of the general appropriation bills as passed by
 the legislature shall contain an itemized statement of estimated revenue by major source in
 each operating fund for the ensuing fiscal period, the total of which shall not be less than the
 total of all appropriations made from each fund in the general appropriation bills as passed.
