The Republican National Committee and the Republican Party of Pennsylvania have asked the state’s highest court to delay a ruling that could affect thousands of voters next month while it asks the U.S.

The Pennsylvania Supreme Court ruled that voters who cast faulty mail-in ballots can afterward cast provisional votes. In a four to three ruling, the state Supreme Court found that the Butler County Board of Elections must count the provisional ballots of voters whose mail-in ballots were rejected for not properly following instructions.
