Supreme Court blocks most of Arizona immigration law but leaves status checks

The Supreme Court rules in Arizona v. United States on June 25, 2012, striking down several provisions of Arizona's SB 1070 but allowing the state's immigration-status check provision to take effect for the moment. The Court says federal law preempts much of Arizona's immigration scheme. Civil rights groups continue to warn that status checks can produce racial profiling of Latino residents. The ruling defines the boundaries of state immigration enforcement while leaving a core civil rights concern unresolved.
