Pennsylvania county election officials must count provisional ballots cast by voters whose mail-in ballots were rejected due to errors, the state's highest court ruled.

Pennsylvania’s highest court has ruled people whose mail ballots are rejected for not following technical procedures in state law can cast provisional ballots.

The Pennsylvania Supreme Court said voters should be allowed to cast provisional ballots in person at their polling place if their mail ballots are rejected because of certain defects, in a ruling Wednesday that could give thousands of Pennsylvanians the opportunity to vote even if their mail ballots were disqualified due to errors.
