A conservative legal organization is ratcheting up its opposition to the requirement in Illinois that mail-in ballots be counted for 14 days after Election Day by calling on the U.S. Supreme Court to reverse federal court rulings that upheld the law because three Republican plaintiffs lacked the legal standing to challenge it.

The appeal, filed Tuesday by the organization Judicial Watch, also asks the nation’s highest court to clarify rulings about who has the right to appeal post-Election Day challenges, after many lawsuits contesting individual state results of the 2020 election filed on behalf of Donald Trump were tossed for lack of standing. Judicial Watch was among several groups that assisted Trump in seeking to halt the counting of mail-in ballots after Election Day four years ago when Trump lost to President Joe Biden.

By having the U.S. Supreme Court overturn the Illinois rulings and remand the case to the lower courts, it would allow them “to consider the merits of the important questions raised by the petitioner’s claims,” Justice Watch contended.
