(720 ILCS 5/7-1)
(from Ch. 38, par. 7-1)
force in defense of person.
(a) A person is justified in the use of force against another when and to
the extent that he reasonably believes that such conduct is necessary to
defend himself or another against such other's imminent use of unlawful
force. However, he is justified in the use of force which is intended or
likely to cause death or great bodily harm only if he reasonably believes
that such force is necessary to prevent imminent death or great bodily harm
to himself or another, or the commission of a forcible felony.
(b) In no case shall any act involving the use of force justified under this Section give rise to any claim or liability brought by or on behalf of any person acting within the definition of "aggressor" set forth in Section 7-4 of this Article, or the estate, spouse, or other family member of such a person, against the person or estate of the person using such justified force, unless the use of force involves willful or wanton misconduct.
