72 Pa. Stat. § 5020-105
The provisions of this act so far as they are the same as those of existing laws are intended as a continuation of such laws, and not as new enactments.
The repeal by this act of any act of Assembly, or part thereof, shall not revive any act, or part thereof, heretofore repealed or superseded.
All local acts of Assembly applying to particular counties or political subdivisions thereof, and not heretofore repealed, shall continue in force, and any provisions of this act inconsistent therewith shall not apply to the counties or political subdivisions thereof affected by such local laws. The reenactment by this act of any act of Assembly, or part thereof, that has heretofore been repealed by any local act of Assembly, in so far as it applied to a particular county or political subdivision thereof, shall not revive or extend the provisions so reenacted to such county or political subdivision thereof.
Whenever the provisions of this act are inconsistent with any law relating to or administered by any board of revision of taxes, or board for the assessment and revision of taxes, in counties of the first, second or third class, the laws relating to and administered by such boards, and not included in this act, shall apply, and the inconsistent provisions of this act shall not apply to such classes of counties, but shall be in full force as to all other classes of counties, except as affected by local laws.
The provisions of this act shall not affect any act done, liability incurred, or right accrued or vested, or affect any suit, proceeding or prosecution pending or to be instituted to enforce any right or penalty or punish any offense under the authority of any act of Assembly repealed by this act.
Any person holding office under any act of Assembly repealed by this act shall continue to hold such office until the expiration of the term thereof, subject to the conditions attached to such office prior to the passage of this act.
