The Supreme Court on Monday said it would not consider a case involving an Arizona immigration law that makes it illegal to harbor or transport illegal immigrants.

A lower court found the provision was vague and trumped by federal law, and placed an injunction on this portion of the law. That injunction was upheld by the 9th Circuit Court of Appeals, and on Monday, the Supreme Court declined to weigh in on the matter.


The provision is part of Arizona's controversial immigration law that was signed in 2010, and would make it a crime to knowingly transport or move an illegal immigrant in Arizona "in furtherance of the alien's unlawful presence in the United States." It also makes it illegal to attempt to conceal or harbor these individuals from authorities.

The American Civil Liberties Union, which brought the initial court challenge along with a number of immigration groups, said the law would have made it a crime to give relatives a ride if they were in the country illegally or for landlords to rent out a home to them.

The harboring statute is one of a number of issues that was not addressed by the high court in its previous ruling on Arizona's immigration law.

In 2012, the Supreme Court upheld the portion of the Arizona law that allowed law enforcement to check the immigration status of detained individuals. But it struck down a number of other provisions, ruling federal law preempted the state law in those cases.
