DALLAS -- A judge blocked the Texas Department of Public Safety on Thursday from continuing to enforce new rules that prevent some legal immigrants from obtaining driver's licenses and identification cards. State District Judge Orlinda L. Naranjo in Austin issued a temporary injunction and found DPS acted outside its scope of authority when it adopted the policy last year. "This case is not about illegal immigrants obtaining driver licenses, it is about legal residents who have been denied or have been threatened a denial of a driver license," Naranjo wrote.
