The U.S. Court of Appeals for the Ninth Circuit rejected a request to review the Arizona E-Verify law, leaving intact the requirements that all employers use E-Verify or face penalties.

Several opponents of the legislation, including Arizona Contractors Association, the Arizona Chamber of Commerce & Industry and the pro-illegal immigration advocacy group Chicanos Por La Causa, claimed that the law violated the U.S. Constitution and federal law. The Ninth Circuit's decision to not revisit the case confirms the prior ruling that the law does not interfere with the federal government's authority to enforce immigration laws.

Arizona is one of three states -- Mississippi and South Carolina -- that requires mandatory usage of E-Verify for all employers.
