The U.S. Supreme Court will hear the following case today: Chamber of Commerce of the United States v. Whiting, 09-115.

The case involves the constitutionality of an Arizona state law that requires employers to check the immigration status of job applicants through a federal computer database, despite the fact that the federal law makes such checks voluntary. The Arizona law provides for the revocation of the business license of state companies that hire undocumented workers. The question presented is whether these provisions in the Arizona State law are pre-empted by federal immigration laws.
