Okla. Stat. tit. 36, § 36-317: Witnesses or evidence

A. The Insurance Commissioner may take depositions, subpoena

witnesses or documentary evidence, administer oaths, and examine

under oath any individual relative to the affairs of any person

being examined, or relative to the subject of any hearing or

investigation.

B. All administrative subpoenas shall be served in the same

manner as if issued from a district court or in accordance with the

Administrative Procedures Act. If any person fails to obey a

subpoena lawfully served, the Commissioner may forthwith report such

disobedience, together with a copy of the subpoena and proof of

service thereof, to the district court of the county in which the

person was required to appear, and such court shall forthwith cause

such person to be produced and shall impose penalties as though the

person had disobeyed a subpoena issued out of such court.
