<p>On April 25, 2012, the case of the State of Arizona v. the United States was heard by the United States Supreme Court.  Oral arguments were given to the Court by lawyers for the U.S. Department of Justice and the State of Arizona.  The court will review the case and issue a ruling in a few months.  The Arizona law supplements federal law and allows Arizona law enforcement officers to detain persons suspected of being illegally in the United States. The United States has challenged the Arizona law claiming that only the federal government has the authority to enforce immigration laws.</p>
