Warrant for witness after summons

If the person to whom the summons is directed does not attend before the court at the time and place mentioned therein, and no reasonable excuse is offered for his non-attendance then, after proof upon oath to the satisfaction of the court that the summons was duly served or that the person to whom the summons is directed wilfully avoids service, the court, being satisfied by proof upon oath that he is likely to give material evidence and that a reasonable sum was paid or tendered or was ready to be paid or tendered to him for his expenses in that behalf, may issue a warrant to apprehend and bring him, at a time and place to be mentioned in the warrant, before the court in order to testify before such court.
