The Pennsylvania Supreme Court has ruled that mail ballots without a date or with an incorrect date cannot be counted, overturning a previous lower court decision that deemed the dating requirement unconstitutional. The court's decision was based on jurisdictional grounds, stating that the original lawsuit did not name all 67 county boards of elections, which led to a lack of jurisdiction for the Commonwealth Court. This ruling has drawn criticism from civil rights groups such as the ACLU, which argue that it undermines voters' rights and could disenfranchise eligible voters over minor paperwork errors. The Republican National Committee heralded the decision as a victory for election integrity in a critical election state. As Pennsylvania prepares for the upcoming election, counties are awaiting court rulings on various challenges before they can finalize and print ballots. The ongoing legal disputes highlight the complexities and challenges surrounding mail-in voting in Pennsylvania since its introduction in 2020.
