N.Y. MHR Law § 21

§ 21. Approval of local laws by elective chief executive officer.\nEvery local law shall be certified by the clerk after its passage by\nsuch body and shall be presented to the elective chief executive\nofficer, if any, for approval by him. If such officer approves it, he\nshall sign it and return it to such clerk; it shall then be deemed to\nhave been adopted. If he disapproves it, he shall return it to the clerk\nwith his objections stated in writing and the clerk shall present the\nsame with such objections to the legislative body at its next regular\nmeeting and such objections shall be entered in its record, journal or\nminutes of proceedings. The legislative body within thirty days\nthereafter may reconsider the same. Such an elective chief executive\nofficer who is a member of the legislative body shall not be entitled to\nvote on such reconsideration. If after such reconsideration such local\nlaw is repassed by a vote of at least two-thirds of the total voting\npower of the legislative body, exclusive of such officer, it shall be\ndeemed adopted, notwithstanding the objections of such officer. Only one\nvote shall be had upon such reconsideration. The vote shall be taken by\nayes and noes, and the names of the members present and their votes\nshall be entered in the record, journal or minutes of proceedings. If\nwithin thirty days after a local law shall have been presented to him\nsuch officer shall neither approve it nor return it to the clerk with\nhis objections, it shall be deemed to be adopted in like manner as if he\nhad signed it. At any time prior to such adoption or to the return of a\nlocal law by such officer, as the case may be, the legislative body may\nrecall the same and reconsider its action thereon.\n
