274. A person who has been called and has received the prescribed advance is required to attend at court under pain of being compelled.
If the person fails to attend and the court considers that their testimony would be useful, it may order them to pay all or part of the costs caused by the failure to attend and issue an arrest warrant, which is executed by a bailiff.
The person may be held in custody under the warrant until they testify or are released subject to conditions determined by the court. Examination of any witness held in custody must begin without delay.
