Upon the failure or refusal of a person to obey a subpoena, the department may petition a court of competent jurisdiction and, upon proper showing, the court may enter an order compelling the witness to appear and testify or produce documentary evidence. Failure to obey the court order shall be punishable as contempt of court. When subpoenaed, a person shall attend as a witness at the place specified in the subpoena. Witnesses shall be paid the same fees and mileage as are paid to witnesses in the courts of this Commonwealth. Fees, mileage and expense necessarily incurred in securing the attendance and testimony of witnesses shall be itemized, charged against and paid by the person being examined.
