SECTION II. CRIME
CHAPTER 8. Circumstances Excluding Criminality of Acts
Article 42. Extreme Necessity
(1) An act shall not be deemed to be a crime when interests protected by the present Code are violated due to an extreme necessity, i.e. in order to eliminate a danger threatening a person's life, health, rights, interests of the society and state if this danger couldn't be eliminated by any other means and the harm caused is less significant than the harm prevented.
(2) An excess of extreme necessity is deemed to be an injurious action not corresponding to the character and degree of the danger , and circumstances under which the danger was eliminated when the harm caused was equal or more significant than the harm prevented. Such excess involves criminal liability only in the event if an injurious action is committed intentionally.
(3) When estimating lawfulness of an act committed in the state of extreme necessity the character and degree of the danger, actual possibility and reality of its coming, real possibility of a person in order to prevent it, his emotional state and other circumstances are taken into account.
1. In addition to other grounds for excluding criminal responsibility provided for in this Statute, a person shall not be criminally responsible if, at the time of that person's conduct:
(c) The person acts reasonably to defend himself or herself or another person or, in the case of war crimes, property which is essential for the survival of the person or another person or property which is essential for accomplishing a military mission, against an imminent and unlawful use of force in a manner proportionate to the degree of danger to the person or the other person or property protected. The fact that the person was involved in a defensive operation conducted by forces shall not in itself constitute a ground for excluding criminal responsibility under this subparagraph;
