One day before the 50th anniversary of the Voting Rights Act, one of the most conservative federal appeals courts in the country wielded that law to strike down a Texas voter suppression law. A unanimous panel of the United States Court of Appeals for the Fifth Circuit, in an opinion written by a George W. Bush appointee, held that Texas’s voter ID law violates the Voting Rights Act and must, at the very least, be significantly weakened. Though the court did not accept every argument raised against the state’s voter ID law, and its opinion does not go nearly as far as a trial judge’s decision which also struck down this law, it is a significant blow to the state’s efforts to make voting more difficult.

Voter ID laws are a common obstacle raised, mostly by right-leaning lawmakers, in front of citizens seeking to exercise their right to vote. Though stringent voter ID laws, which require voters to show a photo ID before they can cast a ballot, are often justified as a shield against voter fraud, the kind of fraud these laws target barely exists. A Wisconsin study, for example, found just seven cases of fraud out of 3 million votes cast during the 2004 election — and none of these seven cases were the kind of in-person voter fraud that is prevented by a voter ID law. Similarly an investigation by former Iowa Secretary of State Matt Schultz (R) found exactly zero cases of in-person voter fraud over the course of several elections.

What voter ID laws do accomplish, however, is they disproportionately disenfranchise groups that tend to prefer Democratic candidates over Republicans. As Judge Catharina Haynes explained in her opinion on behalf of the Fifth Circuit, one analysis determined that “Hispanic registered voters and Black registered voters were respectively 195% and 305% more likely than their Anglo peers to lack” a voter ID in the state of Texas. Indeed, even Texas’s own numbers confirmed that voter ID laws disproportionately impact racial minorities. Their own expert “found that 4% of eligible White voters lacked SB 14 ID, compared to 5.3% of eligible Black voters and 6.9% of eligible Hispanic voters.”

In a 147-page ruling [PDF] released Thursday evening, "after hearing and carefully considering all the evidence" presented in the trial which ended on September 22nd, a U.S. District Court in Texas has found that the state's polling place Photo ID law, SB 14, is discriminatory and violates the U.S. Constitution in at least four different ways.

"The Court holds that SB 14 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," U.S. District Court Judge Nelva Gonzales Ramos writes in her ruling. "The Court further holds that SB 14 constitutes an unconstitutional poll tax."
