For the purpose of a proceeding under this chapter, the disciplinary panel may administer oaths and upon its own motion or upon request of any party, shall subpoena witnesses, compel their attendance, take evidence, and require the production of any matter which is relevant to the investigation including, but not limited to, the existence, description, nature, custody, condition, and location of any books, documents, or other tangible items and the identity and location of persons having knowledge of relevant facts or any other matter reasonably calculated to lead to the discovery of material evidence. Upon failure to obey a subpoena or to answer questions propounded by the disciplinary panel, the disciplinary panel may apply pursuant to the Administrative Procedures Act to an administrative law judge for an order requiring the person to appear before the disciplinary panel and to produce documentary evidence and give other evidence concerning the matter under inquiry.
