The left-leaning Pennsylvania Supreme Court has decided some politically charged issues in recent years. Back in 2012, the state Supreme Court ruled that requiring voters to provide identification before voting was unconstitutional. There was the controversial approval of last-minute changes to the state’s Congressional district map in a 2018 gerrymandering case.
In 2020, a state Supreme Court decision required ballots received up to three days after the election to be counted unless a ballot is clearly postmarked after 8 p.m. on Election Day. Other election-related cases have worked through the state’s courts, including questions about the legitimacy of ballot drop-boxes and questions about which mail-in ballots should be counted when the sender fails to sign and date the exterior envelope.
