SCOTUSblog reports three judges of the U.S. Court of Appeals for the D.C. Circuit listened closely, but noncommittally, on Wednesday to a broad constitutional attack on the system of war crimes tribunals now operating at the U.S. military base at Guantanamo Bay, Cuba. The hearing — running more than twice as long as the assigned half-hour — ranged over the trial of Abraham Lincoln’s assassins, a military trial in the Civil War, a sabotage trial during World War II, and an 1895 case involving a Chinese national convicted outside of the regular court system. The point of that exploration was to help the three-judge panel decide whether Congress and the Pentagon have teamed up to create a system of war crimes prosecutions that pushed aside the regular civilian trial courts, in a way that violates the Constitution’s Article III, creating the federal judiciary. The case heard Wednesday seems destined to go to the Supreme Court.
