Definition of Preliminary injunction:
Granted before the commencement of a trial where the plaintiff can satisfy the court that he or she will suffer irreparable harm if the injunction is not immediately granted.

At the end of the trial, the court may decide on a permanent (perpetual) injunction based on the merits of the case. Also called interlocutory injunction or temporary restraining order.
