Government officials wants an appeals court to block the controversial Alabama immigration law from going into full effect, arguing that it opens the door for discrimination against legal immigrants and foreign-born citizens.
The federal government filed the challenge to the 11th Circuit Court of Appeals in Atlanta. It claimed Alabama's new law "is highly likely to expose persons lawfully in the United States, including school children, to new difficulties in routine dealings."
The overhaul allows authorities to question people suspected of being in the country illegally and hold them without bond. It also lets officials check the immigration status of students in public schools.
A federal judge in Alabama upheld those two key aspects of the law, which have already taken effect.
Those provisions that took effect are what help make the Alabama law stricter than similar laws passed in Arizona, Utah, Indiana and Georgia. Other federal judges have blocked all or parts of the laws in those states.
Immigration became a hot issue in Alabama over the past decade as the state's Hispanic population grew by 145 percent to about 185,600. While the group still represents only about 4 percent of the population, some counties in north Alabama have large Spanish-speaking communities and schools where most of the students are Hispanic.
The Justice Department's appeal said parts of the law conflict with federal rules, and that "attempts to drive aliens 'off the grid' will only impede the removal process established by federal law." It also said the legislation could impact diplomatic relations with foreign countries.
"Alabama is not in a position to answer to other nations for the consequences of its policy," it said. "That is the responsibility of the federal government, which speaks for all the states and must ensure that the consequences of one state's foray in to the realm of immigration law are not visited upon the nation as a whole."
It also said requiring officers to report people without adequate credentials to federal immigration officials "unnecessarily diverts resources from federal enforcement priorities and precludes state and local officials from working in true cooperation with federal officials."
