The Secretary may bring an action for an injunction against a person who violates any provision of this subtitle. In an action for an injunction under this section, any finding of the Secretary after a hearing is prima facie evidence of each fact the Secretary determines. On a showing that a person is violating any provision of this subtitle, a court shall grant an injunction without requiring a showing of a lack of an adequate remedy at law. An action for an injunction under this section is in addition to, and not instead of, criminal prosecution taken under § 5-211 of this subtitle or imposition of civil penalties under § 5-210.2 of this subtitle.
