EX PARTE VALLANDIGHAM
In 1863, soldiers arrested, tried and found guilty Democratic Sen. Clement L. Vallandigham of Ohio for violating Army orders against public expressions of Confederate sympathies. He had denounced the War and the Administration at home and in Congress. President Abraham Lincoln banished Vallandigham to rebel territory. He returned and appealed the action in the Supreme Court.
Are the military proceedings constitutional?
The Court held, unanimously, that it had no jurisdiction over appeals from military courts.
