10 U.S.C. § 803: Art. 3. Jurisdiction to try certain personnel

Subject to section 843 of this title (article 43), a person who is in a status in which the person is subject to this chapter and who committed an offense against this chapter while formerly in a status in which the person was subject to this chapter is not relieved from amenability to the jurisdiction of this chapter for that offense by reason of a termination of that person’s former status. Each person discharged from the armed forces who is later charged with having fraudulently obtained his discharge is, subject to section 843 of this title (article 43), subject to trial by court-martial on that charge and is after apprehension subject to this chapter while in the custody of the armed forces for that trial. Upon conviction of that charge he is subject to trial by court-martial for all offenses under this chapter committed before the fraudulent discharge. No person who has deserted from the armed forces may be relieved from amenability to the jurisdiction of this chapter by virtue of a separation from any later period of service. A member of a reserve component or the Space Force who is subject to this chapter is not, by virtue of the termination of a period of active duty or inactive-duty training, relieved from amenability to the jurisdiction of this chapter for an offense against this chapter committed during such period of active duty or inactive-duty training.
