What are the facts?
Lambdin P. Milligan, a civilian, was arrested during the Civil War in Indiana, a state not in active rebellion. He was charged with conspiracy against the United States, inciting insurrection, and aiding the Confederacy. Importantly, his arrest, trial, and sentencing to death were carried out by a military tribunal, despite the fact that Indiana's civilian courts were open and operational. Milligan petitioned for habeas corpus, arguing that his constitutional rights had been violated because he was tried and sentenced by a military court instead of a civilian one.
What is the legal issue?
Whether a non-combatant civilian citizen in a loyal state, where the civil courts are open and functioning, can be tried by a military tribunal.
What rule applies?
Military tribunals cannot try civilians when civilian courts are available and operational, as it would violate constitutional rights providing for judicial processes and the protections of the Bill of Rights.
What did the court hold?
The Supreme Court held that it was unconstitutional to try Milligan, a civilian, by a military tribunal when the civilian courts were available and in session. Military tribunals cannot supplant civilian judicial processes absent the unavailability of civilian courts.
What is the reasoning?
The Court reasoned that the U.S. Constitution, including the Bill of Rights, provides specific protections that cannot be overridden by military authority except under very narrow circumstances. Since civilian courts in Indiana were open, their jurisdiction was properly able to adjudicate such cases, making the use of military tribunals unlawful. The Court emphasized the importance of separation of powers and the need to maintain a distinct and effective judicial system, even during times of national emergency or war.
