Pennsylvania cannot count undated mail-in ballots, says state supreme court

Ruling of 4-3 ends issue in which some Democratic counties ignored precedent and counted ballots that weren't dated

Pennsylvania counties must not count mail-in ballots from voters who did not date their envelopes, the state supreme court ruled on Monday, ending a simmering issue in which some Democratic counties were ignoring prior court rulings and counting the ballots anyway.

[W]e have clarified that mail-in and absentee ballots that fail to comply with the requirements of the Pennsylvania Election Code, shall not be counted for purposes of the election held on November 5, 2024," the majority wrote.
