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.

- League of Women Voters of Pa. v. Commonwealth, 178 A.3d 787 (Pa. 2018): Plaintiffs challenged the General Assembly’s enacted congressional plan as an unconstitutional partisan gerrymander in violation of the Pennsylvania Constitution’s Free and Equal Elections Clause. On January 22, 2018 the state Supreme Court ruled that the congressional plan violated the state constitution’s Free and Equal Elections Clause and on February 7, 2018, issued an opinion outlining its rationale and ordering the General Assembly to enact a remedial plan by February 15, 2018.
- League of Women Voters of Pa. v. Commonwealth, 181 A.3d 1083 (Pa. 2018): After the Republican-controlled General Assembly failed to pass a remedial congressional plan, the Pennsylvania Supreme Court ordered the adoption of its own congressional plan on February 19, 2018, for use in the 2018 and future elections.

On January 25, 2012, the state Supreme Court ruled that the 2011 legislative plan violated the state constitution and remanded the plan back to the commission to be redrawn, but allowed the 2012 elections to proceed using the prior decade’s districts.
- Pileggi v. Aichele, 843 F.Supp.2d 584 (E.D. Pa. 2012): After the Pennsylvania Supreme Court invalidated the 2011 legislative plan and ordered the 2001 plan be used for the 2012 elections, plaintiffs filed a federal lawsuit seeking to enjoin the use of the 2001 plan on the grounds that population shifts had caused the 2001 districts to be malapportioned in violation of the one person, one vote constitutional principle. On February 8, 2012, the district court ruled in favor of the defendants, finding that the special circumstances of the case required the 2012 elections to proceed under the only valid plan then in existence.
- Holt v. 2011 Legislative Reapportionment Comm’n, 67 A.3d 1211 (Pa. 2013): After the Legislative Reapportionment Commission adopted its remedial legislative plans on June 8, 2012, plaintiffs again challenged it as violating the state constitution on the grounds it unnecessarily divided political subdivisions, was not sufficiently compact, was drawn to secure partisan advantage, and violated minority voting rights protected by the Voting Rights Act and Due Process Clause. On May 8, 2013, the Pennsylvania Supreme Court ruled in favor of the defendants on all claims and upheld the plans as valid.

- Vieth v. Pennsylvania, 195 F.Supp.2d 672 (M.D. Pa. 2002): Plaintiffs filed a federal lawsuit challenging the General Assembly’s enacted congressional plan as violating the constitutional one person, one vote principle.
