Congressional maps are enacted by the State General Assembly. The Governor can veto the plans.
The General Assembly can override a veto with a two-thirds vote. No party currently has a veto-proof majority in either chamber.
The Pennsylvania Legislative Reapportionment Commission draws the state legislative districts. It is a five-member commission. Legislative majority and minority leaders either serve on the Commission or appoint a member in their place. The four original members name a fifth, who will be the chair. If the fifth member is not appointed within 45 days, the Pennsylvania Supreme Court selects the fifth member by a majority vote. The chairman of the Commission must be a citizen of the state, but cannot be a local, state, or federal official who gets paid for their services.
Before 90 days pass since either all the Commissioners are appointed or the census data becomes available, whichever is later, the Commission submits an initial district map to an elections officer. A 30-day public commentary period follows, during which the Commission can edit the map. If there are edits, the Commission has 30 days after the filing of exceptions to submit a new plan to the elections officer. Should no exceptions be made in this period, or in the case that they have been made and have been acted upon, the newest plan becomes law. Any citizen may appeal to the State Supreme Court within 30 days after the maps are sent to the elections officer to argue the new plan is illegal. If the new map is determined to be illegal, the Supreme Court instructs the Commission to redraw the maps. The redistricting plan becomes law once the Court decides an appeal or when 30 days end without an appeal being filed. The Commission may pass maps with a majority vote.
Challenges to the maps are litigated in the State Supreme Court.
