CHICAGO - On June 2, 2025, the U.S. Supreme Court announced that it agreed to hear Congressman Mike Bost (IL-12) and Judicial Watch’s case challenging an Illinois law that unconstitutionally extends Election Day for 14 days beyond the date established by federal law.

“Illinois voters deserve to know the results of their elections as early as possible,” said ILGOP Chair Kathy Salvi. “Only ballots received by Election Day should be counted – not ballots received up to two weeks after the election. Illinois’ ballot acceptance window creates a dangerous opportunity for bad actors that further erodes election integrity. The Illinois Republican Party will always support efforts to strengthen and secure our election process.”

“With the American people’s confidence in our elections at a discouraging low point, it’s more important than ever we work to restore their trust,” said Bost. “I believe a big part of that effort is ensuring all votes are tallied by Election Day, not days or weeks later. I am thankful the U.S. Supreme Court has agreed to hear my appeal of Illinois’ election law. This is a critical moment for the rule of law and election integrity.”

In Illinois, mail-in ballots are still counted if they arrive up to 14 days after Election Day. Even if a ballot doesn’t have a postmark, it may still be accepted if it is dated on or before Election Day. Last year, a Seventh Circuit panel determined that Congressman Bost could not challenge Illinois’ ballot counting provision. Congressman Bost introduced his suit in May, 2022.
