Compelling attendance. In case of failure of a witness to attend, the court or judge issuing the subpoena, upon proof of the service thereof and of the failure of the witness, may issue a warrant to the sheriff of the province, or his deputy, to arrest the witness and bring him before the court or officer where his attendance is required, and the cost of such warrant and seizure of such witness shall be paid by the witness if the court issuing it shall determine that his failure to answer the subpoena was willful and without just excuse.
