Such subpoenas shall be served by the sheriff or any other officer authorized by law to serve process in this state. No person shall be excused from attending and testifying, or from producing books, papers and records before the board or a court, or from obedience to the subpoena of the board or a court, on the ground or for the reason that the testimony or evidence, documentary or otherwise, required of such person may tend to incriminate the person or subject the person to a penalty or forfeiture; provided, that nothing herein shall be construed as requiring any person to produce any books, papers or records, or to testify in response to any inquiry, not pertinent to some question lawfully before such board or court for determination. No natural person shall be subjected to criminal prosecution or to any penalty or forfeiture for or on account of any transaction, matter or thing concerning which the person may be required to testify or produce evidence, documentary or otherwise, before the board or court, or in obedience to its subpoena; provided, that no person testifying shall be exempt from prosecution and punishment for perjury committed in so testifying.
