N.Y. Const. art. IV, § 7

Every bill which shall have passed the senate and assembly shall, before it becomes a law, be presented to the governor; if the governor approve, he or she shall sign it; but if not, he or she shall return it with his or her objections to the house in which it shall have originated, which shall enter the objections at large on the journal, and proceed to reconsider it. If after such reconsideration, two-thirds of the members elected to that house shall agree to pass the bill, it shall be sent together with the objections, to the other house, by which it shall likewise be reconsidered; and if approved by two-thirds of the members elected to that house, it shall become a law notwithstanding the objections of the governor. In all such cases the votes in both houses shall be determined by yeas and nays, and the names of the members voting shall be entered by yeas and nays, and the names of the members voting shall be entered on the journal of each house respectively. If any bill shall not be returned by the governor within ten days (Sundays excepted) after it shall have been presented to him or her, the same shall be a law in like manner as if he or she had signed it, unless the legislature shall, by their adjournment, prevent its return, in which case it shall not become a law without the approval of the governor. No bill shall become a law after the final adjournment of the legislature, unless approved by the governor within thirty days after such adjournment. If any bill presented to the governor contain several items of appropriation of money, the governor may object to one or more of such items while approving of the other portion of the bill. In such case the governor shall append to the bill, at the time of signing it, a statement of the items to which he or she objects; and the appropriation so objected to shall not take effect. If the legislature be in session, he or she shall transmit to the house in which the bill originated a copy of such statement, and the items objected to shall be separately reconsidered. If on reconsideration one or more of such items be approved by two-thirds of the members elected to each house, the same shall be part of the law, notwithstanding the objections of the governor. All the provisions of this section, in relation to bills not approved by the governor, shall apply in cases in which he or she shall withhold approval from any item or items contained in a bill appropriating money.
