Notes of Decisions

Intent and purpose of this sec­tion is simply to excuse violator from pros­e­cu­­tion on account of viola­tion which resulted from independent, intervening cause such as act of God, war, strife, riot or other similar cause; it does entitle defendant to instruc­tion that willful miscon­duct must be shown to be proximate cause of viola­tion charged in indict­ment.
