Julie Pace, a lawyer representing the business groups, says the object of the challenge is to stop states from creating differing immigration laws that make it cumbersome for businesses that operate in multiple states.

The employer sanctions law is separate from a new Arizona immigration law that requires police to question the immigration status of people they suspect are in the country illegally. The court's next term begins in October.
