N.Y. Jud. Law § 117
As to all motions, actions or proceedings submitted to an official referee by stipulation of the parties appearing therein, or order of the court, except matrimonial actions, the same shall be deemed duly referred to said official referee and he shall proceed therein with the same power and authority as a justice presiding at a regular special term of the supreme court and entertain and grant motions for a new trial, grant stays and orders to show cause, and he shall have similar jurisdiction and authority as to any other action or proceeding referred to him by order of the supreme court including matrimonial actions. Every official referee shall have the power to administer oaths and take acknowledgments; the violation of an order of such official referee may be punished as for a contempt of court by the court at special term.
