A Pennsylvania judicial candidate asked the U.S. Supreme Court on Friday to block a federal appellate court decision requiring undated mail ballots to be counted, a ruling that could affect primary election returns, including the recount ahead in the U.S. Senate Republican primary.

The application was filed by David Ritter, a Republican candidate in the 2021 election for the Lehigh County Court of Common Pleas. The U.S. Court of Appeals for the Third Circuit, in a suit brought by a group of individual voters, ruled the county has to count over 250 undated ballots, a number likely to erase Ritter’s lead “three times over,” wrote his counsel, Cameron Norris of Consovoy McCarthy.
