18 Pa.C.S. § 510: Justification in property crimes.

Conduct involving the appropriation, seizure or destruction of, damage to, intrusion on or interference with property is justifiable under circumstances which would establish a defense of privilege in a civil action based thereon, unless:

(1) this title or the law defining the offense deals with the specific situation involved; or

(2) a legislative purpose to exclude the justification claimed otherwise plainly appears.
