Chief Justice John Roberts wrote the Court's decision in Chamber of Commerce v. Whiting. The case involved an Arizona law called the 2007 Legal Arizona Workers Act. It authorizes state courts to suspend and revoke the business licenses of businesses that knowingly hire "unauthorized aliens."
"The federal law allows States to take licensing action. The word ‘license' includes the many forms of legal permission to perform an act, and therefore includes charters, articles of incorporation, etc. The AZ law relies only on determinations made by federal authorities of employment eligibility, and allows employers the same good faith defense as in federal law," according to www.OnTheIssues.org.
