1 Pa. C.S. § 1955
Whenever two or more amendments to the same provision of a statute are enacted at the same or different sessions, one amendment overlooking and making no reference to the other or others, the changes in the statute made by each shall be given effect and all the amendments shall be read into each other. If the changes made in the statute are to any extent in direct conflict with each other, the rules specified in section 1935 of this title (relating to irreconcilable statutes passed by same General Assembly) and section 1936 of this title (relating to irreconcilable statutes passed by different General Assemblies) shall govern. The fact that a later amendment (1) restates language of the original statute which was deleted by an earlier amendment, or (2) fails to restate language inserted by an earlier amendment, does not of itself create a conflict between the two amendments. Amendments are in conflict with each other only if the changes in the statute made by each without considering the inserts and strike-outs of the other cannot be put into operation simultaneously.
