Section 4. Action on budget bills by legislature; effect thereof

The legislature may not alter an appropriation bill submitted by the governor except to strike out or reduce items therein, but it may add thereto items of appropriation provided that such additions are stated separately and distinctly from the original items of the bill and refer each to a single object or purpose. None of the restrictions of this section, however, shall apply to appropriations for the legislature or judiciary.
Such an appropriation bill shall when passed by both houses be a law immediately without further action by the governor, except that appropriations for the legislature and judiciary and separate items added to the governor's bills by the legislature shall be subject to approval of the governor as provided in section 7 of article IV.
