Wash. Rev. Code § 7.48A.120
If the court finds at the hearing for an injunction, that the accounting, inventory, personal property, and contents of the place alleged to be a nuisance provide evidence of a moral nuisance as defined by RCW 7.48A.020(1) through (4), the court may order the defendant to produce to the plaintiff a limited number of original films, film plates, publications, videotapes, any other obscene matter, and other discovery materials the court determines is necessary for evidentiary purposes to resolve the action on the merits.
The court may issue a temporary injunction enjoining the defendant and all other persons from removing or in any manner interfering with the court-ordered discovery. This discovery procedure supplements and does not replace any other discovery procedures and rules generally applicable to civil cases in this state.
