The State Administrator or the State Administrator’s designee may investigate a potential violation of § 13–238 or § 13–250 of this title. The State Administrator or the State Administrator’s designee shall: notify a person that is subject to an investigation under this section of the circumstances that gave rise to the investigation; and provide the person ample opportunity to be heard at a public meeting of the State Board. In furtherance of an investigation under this section, the State Administrator or the State Administrator’s designee may issue a subpoena for the attendance of a witness to testify or the production of records.
