The Board may appear in its own name and apply to courts having jurisdiction for injunctions to prevent violations of this Chapter or of rules issued pursuant thereto, and such courts are empowered to grant such injunctions regardless of whether criminal prosecution or other action has been or may be instituted as a result of such violation. A single act of unauthorized or illegal practice shall be sufficient, if shown, to invoke the injunctive relief of this section or criminal penalties under N.C. Gen. Stat. § 83A-16 (1979, c. 871, s. 1.)
