The law recognizes that some bad acts are irreversible and provides the remedy of a temporary restraining order. Temporary restraining orders can be entered without notice to the restrained parties. Such a powerful procedure can be abused, which is why temporary restraining orders can be appealed. One of the rules of temporary restraining orders is that a TRO has a short period of validity and must be followed quickly by a hearing with all parties present, which may result in a temporary injunction until a real trial can get to its turn on the docket. The temporary injunction can be appealed, too. If there is a permanent injunction, as is common, the judgment in that case is final, and, therefore, appealable.
