PART II - GENERAL PRINCIPLES OF CRIMINAL LIABILITY
Self defence
20. (1) No person shall be criminally responsible for the use of force in repelling an unlawful attack -
(a) upon himself or herself or another person if -
(i) it was not reasonable to avail himself or herself of any means of retreat of which he or she was aware; and
(ii) the degree of force used in repelling the attack was no greater than that which was reasonably necessary in the circumstances;
(b) upon his or her property or the property of another provided that the means he or she chooses and the degree of force he or she uses in so doing are reasonable in the circumstances.
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;
