Evidence

(a) In Open Court. At trial, the witnesses' testimony must be taken in open court unless a statute, the Rules of Evidence, these rules, or other court rules provide otherwise. For good cause, or on agreement of the parties, and with appropriate safeguards, the court may permit testimony in open court by contemporaneous transmission from a different location. A party must give notice if a witness is unable to testify orally or if testimony by contemporaneous transmission may be necessary. (b) Evidence on a Motion. When a motion relies on facts outside the record, the court may hear the matter on declarations or may hear it wholly or partly on oral testimony or on depositions. (c) Interpreter. If a person with limited English proficiency or a deaf person is involved in a proceeding as a party, witness, person with legal decision-making authority, or person with a significant legal interest in the matter, the court must provide an interpreter.
