Uniform Code of Military Justice
Article 3. Jurisdiction.
(a) A person subject to this Code may be investigated, charged, tried, sentenced, and subjected to judicial review for an offense punishable under this Code without regard to whether the conduct occurred within or outside the United States.
(b) Jurisdiction extends to conduct occurring aboard military vessels or aircraft, upon military property, during deployment, within an area of military operations, or elsewhere when the accused was subject to this Code at the time relevant to the alleged offense.
(c) The existence of military jurisdiction does not by itself extinguish jurisdiction otherwise lawfully possessed by the United States, a State, or another competent authority.
(d) A court-martial shall possess jurisdiction over both the accused and the charged offense before entering judgment.
(e) Lack of subject-matter jurisdiction is not waived by the failure of a party to raise it.
