In Milligan, Administrator of Milligan v. Milledge & Wife, the Supreme Court ruled that a state court could not try and convict a person for treason against the United States when they were living in an area where martial law had been declared but was no longer in effect. The case involved William Milligan who was charged with treason by Georgia state courts while he lived in an area under martial law during the Revolutionary War. The Supreme Court found that since there was no longer any military rule over this region at the time of his trial, it violated both federal and state laws to try him as if there still were. This decision established important precedent regarding civil liberties during times of war or emergency situations and has been cited numerous times throughout history to protect citizens’ rights from being infringed upon by government authorities.

In Milligan, Administrator of Milligan v. Milledge & Wife, the Supreme Court was asked to decide whether a state court had jurisdiction over a case involving an individual who was not a citizen of that state and did not reside there. The majority opinion held that the state court lacked jurisdiction in this particular case because it involved someone from another state. However, Justice Paterson wrote a dissenting opinion arguing that states have inherent authority to exercise their judicial powers within their own borders regardless of citizenship or residency status. He argued further that if such power were denied then states would be unable to protect themselves against foreign enemies or criminals from other jurisdictions and thus could become vulnerable to attack by those outside its boundaries. He concluded by stating his belief that denying states the right to exercise judicial power over non-citizens would lead only “to anarchy and confusion” as each person could claim immunity under laws of different jurisdictions at any given time without consequence for violating them elsewhere
