Conducting a trial in the absence of a party. Trial “in absentia” typically refers to a criminal proceeding in a court of law in which the defendant is not physically present to present a defense and testify on behalf of one’s self. In many jurisdictions the concept of “trial in absentia” is understood to refer to a defendant’s right to be present in a courtroom during criminal proceedings or a criminal trial. Such a conviction where a defendant is not present to defend and answer charges in person may be considered a violation of the principles of natural justice and notions of fair play.
