Civil Procedure
Section 4. Quashing a subpoena. - The court may quash a subpoena duces tecum upon motion promptly made and, in any event, at or before the time specified therein if it is unreasonable and oppressive, or the relevancy of the books, documents or things does not appear, or if the person in whose behalf the subpoena is issued fails to advance the reasonable cost of the production thereof.
The court may quash a subpoena ad testificandum on the ground that the witness is not bound thereby. In either case, the subpoena may be quashed on the ground that the witness fees and kilometrage allowed by these Rules were not tendered when the subpoena was served. (4a, R23)
