WASHINGTON (WUSA/CBS/AP) -- Monday, the Supreme Court upheld part of and struck down part of Arizona's law that cracks down on illegal immigrants.
A controversial part of the 2010 law -- the "stop and check" provision -- which requires police to check the status of someone they suspect is illegally in the United States could go forward. The justices did say that the provision could still be challenged in court.
Three other provisions of the law were struck down: a requirement that all immigrants obtain or carry immigration registration papers, a provision making it a state criminal offense for an illegal immigrant to seek work or hold a job and a provision that would allow police to arrest suspected illegal immigrants without warrants.

Arizona's law S.B. 1070 makes it a crime to be in the state as an undocumented immigrant and compels local law officials to enforce the law.
Only eight of the Supreme Court justices ruled on the case. Associate Justice Elena Kagan recused herself because she served as President Obama's solicitor general when the administration decided to challenge the law.
The U.S. government challenged the law in court, arguing that immigration regulation should be in the hands of the federal government, not the states.
