Summary

Anyone covered by military law who, knowing or believing it could harm the United States or help a foreign nation, gives or tries to give national defense information or materials to a foreign government, faction, or their representatives will be tried by court-martial and punished. If the matter directly involves one of four especially serious topics — nuclear weapons or military spacecraft/satellites and early warning/defense systems; war plans; signals intelligence or cryptography; or any other major weapons system or key part of defense strategy — the punishment must be death or another court-martial sentence. A death sentence is allowed only if all members of the court-martial unanimously find, beyond a reasonable doubt, at least one of the listed aggravating factors and unanimously decide those factors substantially outweigh any mitigating circumstances. The court can consider evidence from the guilt phase, the sentencing phase, or both. The accused may present wide-ranging mitigating evidence. Aggravating factors are: a prior espionage or treason conviction that allowed death or life imprisonment; knowingly creating a grave risk of major damage to national security; knowingly creating a grave risk of death to someone; or any other factor the President adds by regulation.
