(Reuters) -A U.S. appeals court on Friday said it was illegal for states to count mail-in ballots received after Election Day, siding with Republicans in a case challenging Mississippi's five-day grace period. The ruling by a conservative three-judge panel of the New Orleans-based 5th U.S. Circuit Court of Appeals did not strike down Mississippi's law but called into question mail-in voting practices used in about 20 states nationally, in a voting-rights fight that many predict will end up at the U.S. Supreme Court. The judges did not order any immediate changes to Mississippi's procedures and left it up to a lower court to decide what to do next, saying it was important to preserve the status quo ahead of the Nov. 5 election between Democratic Vice President Kamala Harris and Republican former President Donald Trump.
