When a party objects to testimony or documents they should state “I object” and cite the evidence rule or principle and nothing else. You may be tempted, but don’t make a speaking objection.
United States v. Gurfein, NMCCA 2019, is an example of why speaking objections are improper and can cause problems. I have had trial cases where I’ve had to cut trial counsel off from making a speaking objection in front of members. I have appellate cases where the counsel and military judge engaged in a discussion of the objection (sometimes lengthy and detailed) in front of the members–this is improper.
Defense counsel–shut trial counsel down when they make speaking objections in front of members. I know judges want to save time and not inconvenience members, but you have a client who may be adversely affected by what they hear.
