Section 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.1972, Dec. 6, P.L. 1339, No. 290, § 3, imd. effective.
