Section VII · Opinions and Expert Testimony
Rule 703. Bases of an expert's opinion testimony
2024 Manual for Courts-Martial, United States
Recent revisions Summary of changes Cited by (2)An expert may base an opinion on facts or data in the case that the expert has been made aware of or personally observed. If experts in the particular field would reasonably rely on those kinds of facts or data in forming an opinion on the subject, they need not be admissible for the opinion to be admitted. If the facts or data would otherwise be inadmissible, the proponent of the opinion may disclose them to the members of a court-martial only if the military judge finds that their probative value in helping the members evaluate the opinion substantially outweighs their prejudicial effect.
