Wash. CR 43
Summary
(a) Testimony.
(1) Generally. In all trials the testimony of witnesses shall be taken orally in open court, unless otherwise directed by the court or provided by rule or statute. For good cause in compelling circumstances and with appropriate safeguards, the court may permit testimony in open court by contemporaneous transmission from a different location.
(2) Multiple examinations. When two or more attorneys are upon the same side trying a case, the attorney conducting the examination of a witness shall continue until the witness is excused from the stand; and all objections and offers of proof made during the examination of such witness shall be made or announced by the attorney who is conducting the examination or cross examination.
