13-401. Unavailability of justification defense; justification as defense

A. Even though a person is justified under this chapter in threatening or using physical force or deadly physical force against another, if in doing so such person recklessly injures or kills an innocent third person, the justification afforded by this chapter is unavailable in a prosecution for the reckless injury or killing of the innocent third person.

13-402. Justification; execution of public duty

A. Unless inconsistent with the other sections of this chapter defining justifiable use of physical force or deadly physical force or with some other superseding provision of law, conduct which would otherwise constitute an offense is justifiable when it is required or authorized by law.

B. The justification afforded by subsection A also applies if:

1. A reasonable person would believe such conduct is required or authorized by the judgment or direction of a competent court or tribunal or in the lawful execution of legal process, notwithstanding lack of jurisdiction of the court or defect in the legal process; or

A duly licensed physician or a registered nurse or a person acting under his direction, or any other person who renders emergency care at the scene of an emergency occurrence, may use reasonable physical force for the purpose of administering a recognized and lawful form of treatment which is reasonably adapted to promoting the physical or mental health of the patient if:

(a) The treatment is administered with the consent of the patient or, if the patient is a minor or an incompetent person, with the consent of his parent, guardian or other person entrusted with his care and supervision except as otherwise provided by law; or

(b) The treatment is administered in an emergency when the person administering such treatment reasonably believes that no one competent to consent can be consulted and that a reasonable person, wishing to safeguard the welfare of the patient, would consent.

13-404. Justification; self-defense
