In addition to the remedies provided in Sections 49-23-1 through 49-23-29, Mississippi Code of 1972, and which may otherwise exist under the laws of this state, the State Highway Commission is authorized to petition the chancery court of any county where any unlawful or unauthorized outdoor advertising sign, device or display may exist for injunctive or other appropriate relief. The owner or owners of each and every outdoor advertising sign, device or display shall be deemed to be doing business within this state in each and every county in which such owner or owners shall have erected, or cause to be erected, or maintained, and there shall continue to exist, an outdoor advertising sign, device or display. Once jurisdiction over the parties is obtained, such chancery court shall have such jurisdiction over the parties as is necessary in order to determine if any of said owner or owners' outdoor advertising is in violation of the provisions of this chapter, and to enforce the provisions of this chapter, as to each and every outdoor advertising sign, device or display of such owner or owners within this state, wheresoever located. However, any such action shall be res adjudicata only as to the outdoor advertising signs, devices or displays specifically made a part of such action; and the State Highway Commission shall be authorized and empowered to maintain any and all other actions as to other outdoor advertising of such owner or owners wheresoever located, but not specifically made a part of a previous action. The court may award costs of any action brought under this section, including court costs, expenses and reasonable attorney's fees, to the prevailing party.
