Executive approval — veto — item veto by governor. SEC. 16. Every bill which shall have passed the general assembly, shall, before it becomes a law, be presented to the governor. If he approve, he shall sign it; but if not, he shall return it with his objections, to the house in which it originated, which shall enter the same upon their journal, and proceed to reconsider it; if, after such reconsideration, it again pass both houses, by yeas and nays, by a majority of two thirds of the members of each house, it shall become a law, notwithstanding the governor's objections. If any bill shall not be returned within three days after it shall have been presented to him, Sunday excepted, the same shall be a law in like manner as if he had signed it, unless the general assembly, by adjournment, prevent such return. Any bill submitted to the governor for his approval during the last three days of a session of the general assembly, shall be deposited by him in the office of the secretary of state, within thirty days after the adjournment, with his approval, if approved by him, and with his objections, if he disapproves thereof.
