New York Civil Practice Law
Temporary Restraining Order
1. Generally. If, on a motion for a preliminary injunction, the claiming authority shall show that immediate and irreparable injury, loss or damages may result unless the defendant is restrained before a hearing can be had, a temporary restraining order may be granted without notice. Upon granting a temporary restraining order, the court shall set the hearing for the preliminary injunction at the earliest possible time.
2. Service. Unless the court orders otherwise, a temporary restraining order together with the papers upon which it was based, and a notice of hearing for the preliminary injunction, shall be personally served in the same manner as a summons.
