In the original proclamation of martial law in Louisiana the commanding officer announced that civil causes between parties would be referred to the ordinary tribunals. One of the State courts, known as a District Court of the City and Parish of New Orleans, the judge of which took the oath of allegiance to the United States, continued to sit and dispose of business in the usual course. A few months later a citizen of New York sued a military officer before it for ravaging a plantation which he owned in Louisiana, and recovered judgment. A suit upon it was afterwards brought in Maine, where the defendant resided. He pleaded that the property of the plaintiff had been taken to furnish his troops with necessary supplies. The case ultimately came before the Supreme Court of the United States. Here it was thrown out, the court saying that the District Court of New Orleans had no jurisdiction to call military officers to account for acts done under claim of military right.[Footnote: Dow _v._ Johnson, 100 U. S. Reports, 158.] So far, however, as litigation between private parties unconnected with military operations is concerned, a court of this character, established by law, and suffered by the military authorities to continue its sessions, has competent jurisdiction, and its judgments will be enforced in other States.[Footnote: Pepin _v._ Lachenmeyer, 45 New York Reports, 27.] They have no power to entertain criminal charges against those in the military service, who would be punishable by court martial.[Footnote: Coleman _v._ Tennessee, 97 U. S. Reports, 509, 519.] In 1864, during the war, but in Indiana, a State distant from the seat of hostilities, the military commandant of the district ordered the arrest of a private citizen and his trial before a military commission on charges of conspiracy against the United States, as a member of a secret organization known as the Order of American Knights or Sons of Liberty. The trial resulted in his conviction, and a sentence to death, which was approved by the President of the United States. Before it could be executed, he applied to the Circuit Court of the United States for the District of Indiana for a writ of _habeas corpus_. The judges of that court were divided in opinion in regard to the case, but it was decided in his favor when it came before the Supreme Court of the United States.[Footnote: _Ex parte_ Milligan, 4 Wallace's Reports, 2, 121, 127.] The decision was unanimous, but in stating the reasons for it the court was divided in a manner which has not been uncommon since the death of Chief Justice Marshall when any great question of a political nature has been involved. Five justices held that the trial of a civilian by a military commission can never be vindicated in a peaceful State where the courts are open and their process unobstructed. Four justices dissented, and Chief Justice Chase thus summarized their conclusions:
