Ex parte Vallandigham, 68 U.S. (1 Wall.) 243 (1864), is a United States Supreme Court case, involving a former congressman Clement Vallandigham of Ohio, who had violated an Army order against the public expression of sympathy for the Confederate States and their cause. Vallandigham was tried before a military tribunal by Major General Ambrose E. Burnside for treason after he delivered an incendiary speech at Mount Vernon; he then appealed the tribunal's verdict to the Supreme Court, arguing that he as a civilian could not be tried before a military tribunal.
In February 1864, the Supreme Court avoided ruling on the question by instead unanimously holding that they could not take appeals from military tribunals at all.
