The Hearing Examiner, upon motion, may quash or modify a subpoena or subpoena duces tecum for good cause shown, including, without limitation, a showing that the subpoena is unreasonable or oppressive or relates to irrelevant or immaterial matters. Denial of a motion to quash may, in the case of a subpoena duces tecum, be conditioned upon the advancement, by the party who requested the subpoena, of the reasonable cost of producing the books, records or other documents subpoenaed.
