Voting rights advocates celebrated a federal judge's ruling Wednesday that ordered the state of Texas to stop removing voters from registration rolls. 

The order came from U.S. district judge Fred Biery in response to a lawsuit filed by a group of rights groups against Texas Secretary of State David Whitley.

According to NBC News:

The federal judge slammed Whitley and his botched attempt to identify ineligible voters, saying the state officials came up with a solution "inherently paved with flawed results."

Whitley and his staff burdened "perfectly legal, naturalized Americans" with "ham-handed and threatening correspondence, which did not politely ask for information, but rather exemplifies the power of government to strike fear and anxiety and to intimidate the least powerful among us," the judge wrote.

In a statement, the American Civil Liberties Union of Texas, one of the plaintiffs in the suit, welcomed Biery's ruling—specifically the judge's rejection of the premise of the state's purge list.

"Today, the court recognized what we have been saying all along," said the ACLU Texas staff attorney Thomas Buser-Clancy. "This voter purge discriminates against naturalized citizens using a process that the court described as 'ham-handed' and 'threatening.'"

Other groups and advocates, including the national ACLU, weighed in on social media.

Whitley's "purge list," at the center of the suit, overwhelmingly targets naturalized citizens. And the list isn't a corrective to a temporary problem—it's meant to continue to purge voters on a rolling basis.

From the suit (pdf):

Whitley does not intend for the purge to be a one-time event.  Rather, using the flawed methodology that uniquely targets  naturalized citizens, he intends to provide Purge Lists to counties on a monthly basis, thus regularly subjecting naturalized citizens to voter registration requirements to which native-born citizens are not subject, and exposing them to a continuing and ongoing threat of being purged from the voter rolls.

Rights groups involved in the litigation have alleged that the list is meant to intimidate immigrants and make it harder for people to vote in Texas.

"Texas is stirring up anti-immigrant sentiment, undermining the public's faith in our democracy, and preparing to purge thousands of eligible citizens from the rolls," Chiraag Bains, director of legal strategies at Demos, said when the suit was initially filed in federal court.

For now, Biery's order only stops the purge from continuing—a temporary stoppage, but the language of the ruling indicates that Texas will have a difficult road ahead to prove the necessity of the purge.

 "Let this be a message to the rest of the country,"  the Campaign Legal Center, one of the plaintiffs in the suit, said in a statement, "that states will face consequences when they threaten their citizens' right to vote."
