Civilians in loyal states cannot be tried by military tribunals when civilian courts are available.
Professor Notes

Ex parte Milligan is a cornerstone case that establishes the limits of military authority during peacetime, particularly in relation to civilians. A key aspect for professors to emphasis is the Court's steadfast commitment to civil liberties, even amidst the pressures of war. Milligan's arrest and trial, carried out without the involvement of civilian courts, underscore potential abuses of executive and military power and raise significant constitutional questions regarding due process and the right to a fair trial.

Furthermore, the Supreme Court's decision reinforces the principle that the judiciary must remain intact and functional during times of war. The ruling signals to students the importance of maintaining constitutional rights in the face of national security concerns and serves as an early example of judicial pushback against military overreach in democratic governance.
