Md. Const. art. III, § 32

No money shall be drawn from the Treasury of the State, by any order or resolution, nor except in accordance with an appropriation by Law; and every such Law shall distinctly specify the sum appropriated, and the object, to which it shall be applied; provided, that nothing herein contained, shall prevent the General Assembly from placing a contingent fund at the disposal of the Executive, who shall report to the General Assembly, at each Session, the amount expended, and the purposes to which it was applied. An accurate statement of the receipts and expenditures of the public money, shall be attached to, and published with the Laws, after each regular Session of the General Assembly.
