Pennsylvania Consolidated Statutes (PCS)
TITLE 18, CRIMES AND OFFENSES
PART I. PRELIMINARY PROVISIONS
Chapter 5. General Principles of Justification
§ 503. Justification generally.
(a) General rule.–Conduct which the actor believes to be necessary to avoid a harm or evil to himself or to another is justifiable if:
(1) the harm or evil sought to be avoided by such conduct is greater than that sought to be prevented by the law defining the offense charged;
(2) neither this title nor other law defining the offense provides exceptions or defenses dealing with the specific situation involved; and
(3) a legislative purpose to exclude the justification claimed does not otherwise plainly appear.
(b) Choice of evils.–When the actor was reckless or negligent in bringing about the situation requiring a choice of harms or evils or in appraising the necessity for his conduct, the justification afforded by this section is unavailable in a prosecution for any offense for which recklessness or negligence, as the case may be, suffices to establish culpability.
