Redistricting

2020-2021

See also: Redistricting in Pennsylvania after the 2020 census

On February 23, 2022, the Pennsylvania Supreme Court ruled to enact a new congressional map. Over a dozen maps were submitted to the supreme court, including the map approved by the legislature. The court ultimately selected the Carter map in a 4-3 ruling, which was submitted by a group of Pennsylvania citizens who were petitioners in a redistricting-related lawsuit. Justices Debra Todd (D), Sallie Mundy (R), and Kevin Brobson (R) dissented. Spotlight PA's Kate Huangpu wrote that the map is "as similar as possible to the current congressional map, with nearly 90% of residents staying in the same district." This map took effect for Pennsylvania's 2022 congressional elections.

The state supreme court took authority over the redistricting process after Gov. Tom Wolf (D) vetoed the legislature's enacted map on January 26. The Pennsylvania House of Representatives voted to approve the initial map 110-91 on January 12, and the Pennsylvania State Senate voted 29-20 to approve the map on January 24. Following Wolf's veto, the authority for determining a new map initially rested with a lower court, but in a February 2 ruling the supreme court ruled that it would have control over the process to select a new congressional map.

How does redistricting in Pennsylvania work? In Pennsylvania, the statutory authority to draw congressional district boundaries is vested with the Pennsylvania General Assembly. These lines are subject to gubernatorial veto.

State legislative district lines are drawn by a politician commission. Established in 1968, the commission comprises five members:

1. The majority leader of the Pennsylvania State Senate appoints one member.
2. The minority leader of the Pennsylvania State Senate appoints one member.
3. The majority leader of the Pennsylvania House of Representatives appoints one member.
4. The minority leader of the Pennsylvania House of Representatives appoints one member.
5. The first four commissioners appoint a fifth member to serve as the commission's chair. If the commission is unable to reach an agreement, the Pennsylvania Supreme Court must appoint a commission chair.

The Pennsylvania Constitution requires that state legislative districts be contiguous and compact. Further, state legislative districts should "respect county, city, incorporated town, borough, township and ward boundaries." There are no such requirements in place for congressional districts.

2018

On January 22, 2018, the Pennsylvania Supreme Court struck down the state's congressional district map, finding that the map constituted an illegal partisan gerrymander. On February 19, 2018, the court adopted a remedial map for use in the 2018 election cycle. Pennsylvania Republicans filed suit in federal district court to prevent implementation of the new map. The district court dismissed the suit on March 19, 2018. State Republicans also petitioned the Supreme Court of the United States to stay the state supreme court's order pending appeal. The court rejected this request on March 19, 2018. To learn more, see here.
