(a) Within the first 10 days of each calendar year, the Governor shall submit to the Legislature, with an explanatory message, a budget for the ensuing fiscal year containing itemized statements for recommended state expenditures and estimated state revenues. If recommended expenditures exceed estimated revenues, the Governor shall recommend the sources from which the additional revenues should be provided.

(b) The Governor and the Governor-elect may require a state agency, officer or employee to furnish whatever information is deemed necessary to prepare the budget.

(c) (1) The budget shall be accompanied by a budget bill itemizing recommended expenditures.

(2) The budget bill shall be introduced immediately in each house by the persons chairing the committees that consider the budget.

(3) The Legislature shall pass the budget bill by midnight on June 15 of each year.

(4) Until the budget bill has been enacted, the Legislature shall not send to the Governor for consideration any bill appropriating funds for expenditure during the fiscal year for which the budget bill is to be enacted, except emergency bills recommended by the Governor or appropriations for the salaries and expenses of the Legislature.

(d) No bill except the budget bill may contain more than one item of appropriation, and that for one certain, expressed purpose. Appropriations from the General Fund of the State, except appropriations for the public schools and appropriations in the budget bill and in other bills providing for appropriations related to the budget bill, are void unless passed in each house by rollcall vote entered in the journal, two-thirds of the membership concurring.

(e) (1) Notwithstanding any other provision of law or of this Constitution, the budget bill and other bills providing for appropriations related to the budget bill may be passed in each house by rollcall vote entered in the journal, a majority of the membership concurring, to take effect immediately upon being signed by the Governor or upon a date specified in the legislation. Nothing in this subdivision shall affect the vote requirement for appropriations for the public schools contained in subdivision (d) of this section and in subdivision (b) of Section 8 of this article.

(2) For purposes of this section, “other bills providing for appropriations related to the budget bill” shall consist only of bills identified as related to the budget in the budget bill passed by the Legislature.

(f) The Legislature may control the submission, approval, and enforcement of budgets and the filing of claims for all state agencies.

(g) For the 2004-05 fiscal year, or any subsequent fiscal year, the Legislature may not send to the Governor for consideration, nor may the Governor sign into law, a budget bill that would appropriate from the General Fund, for that fiscal year, a total amount that, when combined with all appropriations from the General Fund for that fiscal year made as of the date of the budget bill’s passage, and the amount of any General Fund moneys transferred to the Budget Stabilization Account for that fiscal year pursuant to Section 20 of Article XVI, exceeds General Fund revenues for that fiscal year estimated as of the date of the budget bill’s passage. That estimate of General Fund revenues shall be set forth in the budget bill passed by the Legislature.

(h) Notwithstanding any other provision of law or of this Constitution, including subdivision (c) of this section, Section 4 of this article, and Sections 4 and 8 of Article III, in any year in which the budget bill is not passed by the Legislature by midnight on June 15, there shall be no appropriation from the current budget or future budget to pay any salary or reimbursement for travel or living expenses for Members of the Legislature during any regular or special session for the period from midnight on June 15 until the day that the budget bill is presented to the Governor. No salary or reimbursement for travel or living expenses forfeited pursuant to this subdivision shall be paid retroactively.
