As a result, voters, advocacy groups and the two main political parties have filed lawsuits over everything from the location of polling places to voter registration procedures.

Worobec, after being approached by the state’s branch of the American Civil Liberties Union, agreed to join six other voters from Washington County, near Pittsburgh, who sued their election board. The Republican Party intervened to defend the case and in August a judge ruled that voters must be notified if a mail-in or absentee ballot has an error so voters can mount a challenge or cast a provisional ballot at their polling place.

The case has been appealed to the state’s supreme court.
