1 Pa.C.S. § 1971 – Implied repeal by later statute

(a) Revision or exclusive system covering entire subject.— 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) Uniform mandatory system covering class of subjects.— 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) Other cases.— In all other cases, a later statute shall not be construed to supply or repeal an earlier statute unless the two statutes are irreconcilable.
