Witness (English: witness) refers to the witness related to the case. In criminal or civil proceedings, they provide testimony, describing the person, time and object related to the case or proceedings, in order to assist the judicial trial. The witness is summoned by the plaintiff or defendant or his defense lawyer related to the case or lawsuit, and then the court issues a summons to summon the witness to testify in court.
In some criminal cases, sometimes the defendant may be transferred from the original witness status according to whether the witness is frank or not and the degree of participation. Witness testimony is the evidence to find out the facts of a case, which is valued by the law at all times and in all countries, and is also the most widely used form of evidence in various lawsuits.
In our country, anyone who knows the case has the obligation to testify except those who are physically or mentally defective or young and cannot correctly distinguish right from wrong and express their will. A witness shall truthfully provide testimony, commit perjury or conceal criminal evidence, and shall bear legal responsibility.
