In addition to the authority granted in § 2.2-4022 to issue subpoenas and the right to issue subpoenas granted the several regulatory boards within the Department of Professional and Occupational Regulation, the Director or a designated subordinate shall have the right to make an ex parte application to the circuit court for the city or county wherein evidence sought is kept or wherein a licensee does business, for the issuance of a subpoena duces tecum in furtherance of the investigation of a sworn complaint within the jurisdiction of the Department or a regulatory board to request production of any relevant records, documents and physical or other evidence of any person, partnership, association or corporation licensed or regulated by the Department. The court shall be authorized to issue and compel compliance with such a subpoena upon a showing of reasonable cause. Upon determining that reasonable cause exists to believe that evidence may be destroyed or altered, the court may issue a subpoena duces tecum requiring the immediate production of evidence.
