A member of the organized militia ordered into State active duty by proper authority is not liable civilly or criminally for any act done while discharging a duty. The court shall require a person to file security for the payment of costs that may be awarded to the defendant when the person prosecutes or begins a suit or proceeding: against an officer of the organized militia for an act done by the officer in the officer’s official capacity in the discharge of a duty under this title; against a person acting under the authority or order of an officer of the organized militia; or by virtue of a warrant that an officer of the militia lawfully issues. In all cases, the defendant may make a general denial and give evidence. If the case is dismissed or a verdict or judgment is rendered against the plaintiff, the defendant shall recover treble costs.
