Pennsylvania voters should be allowed to cast a provisional ballot in place of a mail-in ballot that was rejected because of a mistake, like a missing date or a missing secrecy envelope. Two voters sued after Butler County rejected their primary mail-in ballots and then rejected their provisional ballots, too. A state Commonwealth Court panel ruled that state law did not prevent the county from counting their provisional ballots.

The state and national Republican parties joined Butler County in contesting the lawsuit.  They have three days to file an appeal.

This is just the latest decision on mail-in ballots. Last week, the Commonwealth Court ruled in a case out of Philadelphia that election officials cannot reject a mail-in ballot because of a faulty date on the return envelope. Republicans have appealed that decision.
