1. An insubordination or insurrection of armed forces, esp. sailors, against the authority of their commanders; a forcible revolt by members of the military against constituted authority, usu. their commanding officers. [Cases: Armed Services 37; Military Justice 680. C.J.S. Armed Services § 155; Military Justice §§ 63, 114.]
“Both mutiny and failure to prevent, suppress, or report a mutiny are capital offenses…. The elements of mutiny are (1) creation of any violence or disturbance or acting in concert with others to refuse to obey orders (2) with the intent to usurp or override lawful military authority. One fails to prevent, suppress, or report mutiny when he does not take all reasonable means to overcome or report mutiny. Concert of action is not required for mutiny when the accused creates violence or disturbance.” Charles A. Shanor & L. Lynn Hogue, Military Law in a Nutshell 197–98 (2d ed. 1996).
2. Loosely, any uprising against authority.
— Also termed (in both senses) inciting revolt. — mutinous, adj.
