The Fifth Circuit Court of Appeals unanimously upheld a Texas law requiring voters to include matching ID numbers on both mail-in ballot applications and the completed ballots. The rule is part of Senate Bill 1, passed in 2021, which applies to eligible mail-in voters such as seniors and individuals with disabilities. Civil rights groups argue the matching requirement disproportionately affects vulnerable voters and leads to ballot rejections, without significantly preventing fraud. The panel ruled the requirement complies with the Civil Rights Act and supports Texas's interest in preventing election fraud, giving states discretion in securing voter integrity.
