A federal district judge today lifted an injunction on the controversial “show me your papers” provision of Arizona’s SB 1070. Officers are now required for the first time to question the immigration status of individuals they stop who are suspected to be in the country illegally. U.S. District Judge Susan Bolton’s final order comes after a ruling earlier this month that rejected a challenge to the law filed by civil rights groups. After the U.S. Supreme Court declined to strike down the harsh provision, opponents filed a new lawsuit, this time arguing that Latinos would face racial profiling and unreasonably harsh detentions. These decisions, however, merely rejected challenges to the law before it had taken effect and do not preclude subsequent challenges.
