§ 533.18 DECLARATORY JUDGMENT.
   (a)   Without limitation on the persons otherwise entitled to bring an action for a declaratory judgment pursuant to R.C. Chapter 2721, involving the same issue, the following persons have standing to bring a declaratory judgment action to determine whether particular materials or performances are obscene or harmful to juveniles:
      (1)   The chief legal officer of the municipality if and when there is reasonable cause to believe that R.C. § 2907.31 or § 2907.32, or a substantially equivalent municipal ordinance, is being or is about to be violated; and
      (2)   Any person who, pursuant to R.C. § 2907.35(B) or a substantially equivalent municipal ordinance, has received notice in writing from the chief legal officer stating that particular materials or performances are obscene or harmful to juveniles.
   (b)   Any party to an action for a declaratory judgment pursuant to division (a) of this section is entitled, upon the party’s request, to trial on the merits within five days after joinder of the issues, and the court shall render judgment within five days after trial is concluded.
   (c)   An action for a declaratory judgment pursuant to division (a) of this section shall not be brought during the pendency of any civil action or criminal prosecution when the character of the particular materials or performances involved is at issue in the pending case, and either of the following applies:
      (1)   Either of the parties to the action for a declaratory judgment is a party to the pending case; or
      (2)   A judgment in the pending case will necessarily constitute res judicata as to the character of the materials or performances involved.
   (d)   A civil action or criminal prosecution in which the character of particular materials or performances is at issue, brought during the pendency of an action for a declaratory judgment involving the same issue, shall be stayed during the pendency of the action for a declaratory judgment.
   (e)   The fact that a violation of R.C. § 2907.31 or § 2907.32, or a substantially equivalent municipal ordinance, occurs prior to a judicial determination of the character of the material or performance involved in the violation does not relieve the offender of criminal liability for the violation, even though prosecution may be stayed pending the judicial determination.
