The Obama Justice Department objected to the ID laws in both states. The issue went to a special three-judge court in Washington.
Under Section 5 of the VRA, a covered jurisdiction must prove that its proposed new election law will not have a discriminatory retrogressive impact on minority voting.
That is a substantially more difficult standard to meet than the broader constitutional test established by the US Supreme Court in the Indiana voter ID case.
In Wisconsin and Pennsylvania, challenges to the ID laws in those states were litigated by civil rights groups on behalf of minority voters. In contrast, the Texas and South Carolina laws were challenged by the Justice Department under its authority via the VRA.
In the Texas case, a three-judge panel invalidated the law on the grounds that the photo ID requirement would create burdens that fall disproportionately on the poor, including a large number of African-Americans and Hispanics. The panel was made up of judges appointed by Presidents Obama, Bush II, and Clinton.
In the South Carolina case, a different three-judge panel (made up of two judges appointed by Mr. Bush and one by Mr. Clinton) found that the ID law did not have a discriminatory regressive effect on minority voters.
The court granted preclearance for the law to be enforced in elections beginning in 2013 – but not the current election. The judges said more time was necessary for South Carolina to fully implement the new ID law in a way that would avoid any discriminatory retrogressive effect on African-American voters in South Carolina.
