N.Y. Uniform City Ct. Act § 107
The chief administrator of the courts may temporarily assign any judge or justice of a city, town or village court to a city court within the county of such judge's or justice's residence, or any adjoining county within the same judicial district; provided, however, no town or village justice may be temporarily assigned hereunder unless he or she is an attorney admitted to practice law in this state for at least five years. While temporarily assigned hereunder, any such judge or justice shall have the powers, duties and jurisdiction of a judge of the court to which the assignment is made. After the expiration of any temporary assignment hereunder, the judge or justice assigned shall have all the powers, duties and jurisdiction of a judge or justice of the court to which the assignment was made with respect to all matters pending during the term of such temporary assignment. Such judge or justice shall be entitled to such compensation and travel expenses as the chief administrator shall prescribe by rule. For purposes of this section, the temporary assignment of a judge to a city court may include the assignment of a part-time judge of such court to serve in the stead of a full-time judge of such court during the latter's absence or a vacancy in his or her position that has not been filled in accordance with law; provided, however, that such assignment must be for a continuous period of not less than two weeks nor more than three months.
