1. The director may investigate any cause for the discipline of any license or denial of any application pursuant to this chapter. During the course of such investigation, the director shall have the power to inspect any training center, require by subpoena the attendance and sworn deposition of any witness and the production of any documents, records, or evidence that the director deems relevant. Subpoenas shall be served by a person authorized to serve subpoenas of courts of record. In lieu of the production of any document or record, the director may require that a sworn copy of such document or record be delivered to the director.

2. The director may apply to the circuit court of Cole County or of any county where the person resides or may be found for an order upon any person who shall fail to obey a subpoena to show cause why such subpoena should not be enforced. A show cause order and a copy of the application shall be served upon the person in the same manner as a summons in a civil action. If, after a hearing, the circuit court determines that the subpoena should be enforced, the court shall proceed to enforce the subpoena in the same manner as in a civil case.
