The Board may conduct investigations into and, subject to the State budget, may employ an investigative staff to investigate any complaint that alleges facts that constitute: a ground for disciplinary action under § 12-312 of this title; or a violation of this title. On receipt of the results of an investigation made under this section, the Board promptly shall take the action that is appropriate under this title to ensure compliance with this title. If a complaint is made to the Board from a county, municipal corporation, or unit of the State government, the Board reasonably and promptly shall give the county, municipal corporation, or unit notice of the action taken. If the Board concludes that conduct alleged to be a violation of this title may result in irreparable harm to any person, the Board may sue to enforce any provision of this title by ex parte, interlocutory, or final injunction. In seeking an injunction under this subsection, the Board need not: post bond, if the injunction is sought against a person who does not hold a license issued under this title; or allege or prove that an adequate remedy at law does not exist. The Board shall bring suit under this subsection in the circuit court for the county where: the violation allegedly is occurring; the principal place of business of the alleged violator is located; or the alleged violator resides.
