Pennsylvania Statutes Title 1 Pa.C.S.A. General Provisions § 1971. Implied repeal by later statute

(a) Whenever a statute purports to be a revision of all statutes upon a particular subject, or sets up a general or exclusive system covering the entire subject matter of a former statute and is intended as a substitute for such former statute, such statute shall be construed to supply and therefore to repeal all former statutes upon the same subject.

(b) Whenever a general statute purports to establish a uniform and mandatory system covering a class of subjects, such statute shall be construed to supply and therefore to repeal pre-existing local or special statutes on the same class of subjects.

(c) In all other cases, a later statute shall not be construed to supply or repeal an earlier statute unless the two statutes are irreconcilable.
