The purpose of confrontation is to resolve fundamental contradictions in statements about an important fact. It is possible to confront: the accused and a witness, the accused and a co-defendant, or two witnesses. It is only possible to confront two people at the same time, after each has been questioned separately. A record of the confrontation must be made.
A line up is organized in order to find out whether the witness identifies a person (usually the suspect) or an object. Prior to a line up the witness must describe the characteristics of the person or object to be identified. The person or object is shown, lined up with other unknown persons or objects of similar kind. Witnesses must be instructed in the same way as before a standard hearing (see measure standard hearing). The investigating judge must ensure that the witness does not see the persons or objects to be identified before starting the identification. The record concerning this measure must be accompanied by a photo of all persons, who have participated in a line up. If there is a serious risk to the life or body of the witness or to the life or body of his/her close relatives, or if there is a possibility that the person to be identified may interfere with the execution of the measure, the identification shall be carried out in such a way that the witness making the identification is not visible.
