(a) General rule.— No person subject to this part shall, without the person's consent, be tried a second time for the same offense. Prosecution under this part shall not bar prosecution by civil authorities for a crime or offense growing out of the same act or omission committed in violation of the laws of the civil jurisdiction.
(b) Definition of trial.— No proceeding in which an accused has been found guilty by a court-martial upon any charge or specification is a trial in the sense of this section until the finding of guilty has become final after review of the case has been fully completed. However, a proceeding which, after the introduction of evidence but before a finding, is dismissed or terminated by the convening authority or on motion of the prosecution for failure of available evidence or witnesses without any fault of the accused is a trial in the sense of this section.
