The 5th U.S. Circuit Court of Appeals on Wednesday restored several pieces of a 2021 Texas election law that overhauled mail-in and assisted voting, overturning a lower court's block on those provisions.

Five years ago, Texas passed Senate Bill 1, a wide-reaching election law that changed the way local officials administer elections and how some Texans vote, particularly aimed at initiatives Harris County implemented during the COVID-19 pandemic.

The law was denounced by voter advocacy groups, civil rights organizations and Democratic lawmakers, who broke quorum in an attempt to stifle the bill.
