Supreme Court Rules on Arizona Immigration Law

The U.S. Supreme Court today stuck down the majority of Arizona’s SB 1070, but left a key provision standing.  

On a 5-3 ruling, the Court said that a state law cannot undermine federal immigration statutes, but allowed a provision allowing law enforcement officers to question someone’s immigration status.

The decision left both Republicans and Democrats calling the decision a victory.

"I am pleased that the Supreme Court has struck down key provisions of Arizona's immigration law," President Obama said in a statement. "What this decision makes unmistakably clear is that Congress must act on comprehensive immigration reform. A patchwork of state laws is not a solution to our broken immigration system—it's part of the problem."

Arizona Governor Jan Brewer called the court's ruling "a victory for the rule of law" and a "loss" for opponents of her state's approach. Brewer said police engaged in racial profiling would be punished.

"I am confident our officers are prepared to carry out this law responsibly and lawfully. Nothing less is acceptable," she said.
