N.Y. Const. art. VII, § 11

Except the debts or refunding debts specified in sections 9, 10 and 13 of this article, no debt shall be hereafter contracted by or in behalf of the state, unless such debt shall be authorized by law, for some single work or purpose, to be distinctly specified therein. No such law shall take effect until it shall, at a general election, have been submitted to the people, and have received a majority of all the votes cast for and against it at such election nor shall it be submitted to be voted on within three months after its passage nor at any general election when any other law or any bill shall be submitted to be voted for or against. The legislature may, at any time after the approval of such law by the people, if no debt shall have been contracted in pursuance thereof, repeal the same; and may at any time, by law, forbid the contracting of any further debt or liability under such law.
