(a) Whenever the Attorney General or any district attorney has reason to believe that any person is violating any provision of this part, he may bring an action against such person to restrain or enjoin continued violations. With the exception of consent judgments entered before any testimony is taken, a final judgment under this Code section is admissible as prima-facie evidence of such specific findings of fact as may be made by the court which enters the judgment in subsequent proceedings by or against the same person or his successors or assigns.

(b) Any person who violates any provision of this part may be liable for a civil penalty not to exceed $500.00 for each violation. Such penalty may be assessed and recovered in a civil action brought by the Attorney General or any district attorney.
