(a) Except as provided in subsections (b) and (c) of this section, a person is justified in using reasonable physical force upon another person to defend himself or a third person from what he reasonably believes to be the use or imminent use of physical force, and he may use such degree of force which he reasonably believes to be necessary for such purpose; except that deadly physical force may not be used unless the actor reasonably believes that such other person is
(1) using or about to use deadly physical force, or
(2) inflicting or about to inflict great bodily harm.
(b) Notwithstanding the provisions of subsection (a) of this section, a person is not justified in using deadly physical force upon another person if he or she knows that he or she can avoid the necessity of using such force with complete safety
(1) by retreating, except that the actor shall not be required to retreat if he or she is in his or her dwelling, as defined in section 53a-100, or place of work and was not the initial aggressor, or if he or she is a peace officer, a special policeman appointed under section 29-18b, or a motor vehicle inspector designated under section 14-8 and certified pursuant to section 7-294d, or a private person assisting such peace officer, special policeman or motor vehicle inspector at his or her direction, and acting pursuant to section 53a-22, or

(3) by complying with a demand that he or she abstain from performing an act which he or she is not obliged to perform.
(c) Notwithstanding the provisions of subsection (a) of this section, a person is not justified in using physical force when (1) with intent to cause physical injury or death to another person, he provokes the use of physical force by such other person, or (2) he is the initial aggressor, except that his use of physical force upon another person under such circumstances is justifiable if he withdraws from the encounter and effectively communicates to such other person his intent to do so, but such other person notwithstanding continues or threatens the use of physical force, or (3) the physical force involved was the product of a combat by agreement not specifically authorized by law.
