The U.S. Supreme Court has upheld an Arizona law that allows the state to shut down businesses that hire undocumented immigrants. The law has been opposed by both business and immigrant rights organizations. In his dissenting opinion, Justice Stephen Breyer expressed concern that employers in Arizona may now err on the side of not hiring anyone who even looks like he or she could be an undocumented immigrant. The ruling is separate from another controversial Arizona immigration law now making its way through the court system. That law, S.B. 1070, empowers state and local law enforcement to stop, question and arrest whoever they suspect may be an undocumented immigrant.
