The American Civil Liberties Union and ACLU of Pennsylvania filed an emergency lawsuit in federal court to again halt removals under the Alien Enemies Act for people within that court’s judicial district.

Eligible Philadelphia-area voters who submitted mail ballots in the September 17, 2024 special election only to have their votes set aside because they omitted or miswrote the correct date on their outer return envelope – even though the date is not used for any purpose – sued to have their votes count. Plaintiffs urge the courts to rule that enforcing the irrelevant envelope-dating requirement to disenfranchise eligible voters violates the Pennsylvania Constitution's Free and Equal Elections Clause.

Voters in Butler County, Pennsylvania made a mistake in voting their mail ballots in the April 2024 primary election, forgetting to use the required secrecy envelope. Because their mail ballots could not be counted, they went to the polls in Election Day and voted provisional ballots. The County later determined that it would not count their provisional ballots, and the voter’s appealed, arguing that Pennsylvania law requires that when an eligible voter attempts to vote by mail but the mail ballot is rendered void due to some defect like lacking a secrecy envelope, the eligible voter may cast a provisional ballot and have that ballot counted notwithstanding the failed attempt to vote by mail.
