There are, however, certain exceptions to the general rule.If during the course of his trial an accused person so misconducts himself that a proper trial cannot take place, the court may order that the trial proceed in his absence.In summary proceedings an accused may be tried in his absence where he fails to appear in court after being duly notified and he is charged with a statutory offence: for which a sentence of imprisonment cannot be imposed, or in relation to which there is provision authorising procedure in the absence of the accused.In addition, an examination of the facts, held to determine whether an accused person who is insane did the acts or made the omission alleged, may proceed in the absence of the accused where it appears to the court that it is not practical or appropriate for the accused to attend.In civil proceedings decree may be granted in the absence of a defender after service of a writ or summons.
