AUSTIN, Texas — A federal judge likened Texas' strict voter ID requirement to a poll tax deliberately meant to suppress minority voter turnout and struck it down less than a month before Election Day, and mere hours after the U.S. Supreme Court blocked a similar Wisconsin measure.
The twin rulings released Thursday evening represent major and somewhat surprising blows to largely Republican-backed voter identification rules that generally have been upheld in previous rulings nationwide.
Approved in 2011, Texas' law is considered among the nation's harshest and had even been derided in court by the Justice Department as blatant discrimination. Wisconsin's law was passed the same year and has remained a similar political flashpoint.
"We are extremely heartened by the court's decision, which affirms our position that the Texas voter identification law unfairly and unnecessarily restricts access to the franchise," U.S. Attorney General Eric Holder said in a statement. "We are also pleased that the Supreme Court has refused to allow Wisconsin to implement its own restrictive voter identification law."
U.S. District Judge Nelva Gonzales Ramos of Corpus Christi on Texas' Gulf Coast, an appointee of President Barack Obama, never signaled during a two-week trial in September that she intended to rule on the Texas law before Election Day. But the timing could spare an estimated 13.6 million registered Texas voters from needing photo identification to cast a ballot.
The Justice Department says more than 600,000 of those voters, mostly blacks and Hispanics, currently lack eligible ID to vote.
Gonzales Ramos' nearly 150-page ruling says the law "creates an unconstitutional burden on the right to vote, has an impermissible discriminatory effect against Hispanics and African-Americans, and was imposed with an unconstitutional discriminatory purpose."
Republican Texas Attorney General Greg Abbott's office said it would appeal, but in the meantime the state may hold the election under rules that predate the voter ID law.
"The Court today effectively ruled that racial discrimination simply cannot spread to the ballot box," said Sherrilyn Ifill, president and director-counsel of the NAACP Legal Defense and Educational Fund.
In the Wisconsin case, the Supreme Court used a one-page order to grant an emergency stay sought by the American Civil Liberties Union and blocked implementation of the state's voter ID law — overturning a decision by the 7th U.S. Circuit Court of Appeals three days earlier.
Justices Samuel Alito, Antonin Scalia and Clarence Thomas dissented. Wisconsin Attorney General J.B. Van Hollen said in a statement that he believed the law was constitutional and that "nothing in the Court's order suggests otherwise."
Still, Luis Roberto Vera, Jr., national general counsel for League of United Latin American Citizens, said "You can call it the perfect storm against voter ID."
Wisconsin advocates now have 90 days to file a formal petition asking the Supreme Court to take up the case, a deadline so far beyond Election Day that the law may not be reinstated by Nov. 4.
Nineteen states have voter ID laws. Courts nationwide have knocked down challenges — including at the U.S. Supreme Court. But Texas' case attracted unusual attention from Holder.
He brought the weight of his office to the case after the Supreme Court last year struck down the heart of the Voting Rights Act. It had blocked Texas and eight other states with histories of discrimination from changing election laws without permission from the DOJ or a federal court. Holder vowed to wring whatever protections he could from the new and weakened version, and made Texas a first target.
"Even after the Voting Rights Act was seriously eroded last year, we vowed to continue enforcing the remaining portions of that statute as aggressively as possible. This ruling is an important vindication of those efforts," Holder's Thursday statement said.
Abbott is the favorite to replace outgoing Texas Gov. Rick Perry in the Nov. 4 election. His office had argued minorities and whites alike supported the law in public opinion polls. It also pointed to other states, such as Georgia and Indiana, where similar measures have been upheld.
But opponents slammed Texas' law as far more discriminatory. College students IDs aren't accepted by poll workers, but concealed handgun licenses are. Free voting IDs offered by the state require a birth certificate that costs little as $3, but the Justice Department argued that traveling to get those documents imposes an outsize burden on poor minorities.
As a result, attorneys argued, Texas has issued fewer than 300 free voter IDs since the law took effect.
