Whenever an action is initiated under this title to abate an alleged nuisance, an adversary trial on the merits shall be held pursuant to Section 3507.2. If the court finds that the exhibition of the particular motion picture constitutes a nuisance, it shall issue a permanent injunction to abate and prevent the continuance or recurrence of such nuisance. No temporary restraining order or preliminary injunction shall be granted in such an action. An appeal may be taken from an order issuing a permanent injunction, and any injunction issued pursuant to this title by the trial court may be stayed by such court pending the outcome of such appeal. No appeal may be taken from a ruling by the trial court denying an injunction requested under this title.
