In federal district-court civil proceedings, testimony is ordinarily taken in open court; remote contemporaneous testimony requires good cause in compelling circumstances and appropriate safeguards.

Evidence excerpt: 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.
