Tennessee Constitution Art. I, § 25

That no citizen of this State, except such as are employed in the army of the United States, or militia in actual service, shall be subjected to punishment under the martial or military law.  That martial law, in the sense of the unrestricted power of military officers, or others, to dispose of the persons, liberties or property of the citizen, is inconsistent with the principles of free government, and is not confided to any department of the government of this State.
