     § 2503.  Voluntary manslaughter.        (a)  General rule.--A person who kills an individual without     lawful justification commits voluntary manslaughter if at the     time of the killing he is acting under a sudden and intense     passion resulting from serious provocation by:            (1)  the individual killed; or            (2)  another whom the actor endeavors to kill, but he        negligently or accidentally causes the death of the        individual killed.        (b)  Unreasonable belief killing justifiable.--A person who     intentionally or knowingly kills an individual commits voluntary     manslaughter if at the time of the killing he believes the     circumstances to be such that, if they existed, would justify     the killing under Chapter 5 of this title (relating to general     principles of justification), but his belief is unreasonable.        (c)  Grading.--Voluntary manslaughter is a felony of the     first degree.     (Nov. 17, 1995, 1st Sp.Sess., P.L.1144, No.36, eff. 60 days)        1995 Amendment.
