PALM SPRINGS, Calif. -

The United States Supreme Court Monday threw out parts of Arizona's controversial immigration law. 

The Obama Administration had challenged four provisions of the Arizona law.
While the court struck down three of the provisions, it ruled the most debated part of the law can stand.

The justices are going to allow police to check the immigration status of every person that is stopped or arrested, if the officers suspect they're in the country illegally.

"To stop a person just because they look immigrant is scary," said Karan Kler, the executive director of Coachella Valley Immigration Services.  "And there is an issue that where we need to protect the very civil liberties that the United States stands for. "

Most court observers called the ruling a victory for the federal government because the supreme court said only the federal government has the power to set and enforce immigration law.
