Attorneys for Allegheny County elections officials and the Democratic Party argued Tuesday that Friday's 5 p.m. deadline might prevent some votes from counting because of mail delays and other problems people may have had getting their ballots to the county offices in Pittsburgh.
An attorney for the county's Republican party argued against an extension, saying absentee ballots are more prone to being used fraudulently.
Allegheny County Judge Joseph James ruled the ballots can be turned in until the polls close at 8 p.m. on election day. County officials say they typically let people do that anyway during presidential election years.
Ballots accepted after the normal, state-mandated Friday deadline will be sequestered so their validity can be challenged, however.
