Supreme Court Hears Case on Arizona Illegal Workers Law Questions law that allows state to close down businesses that hire undocumented immigrants Jim Malone 08 December 2010 The US Supreme Court is hearing the US Chamber of Commerce's challenge of the law that allows Arizona to suspend the license of a company that employs illegal immigrants. AP The US Supreme Court is hearing the US Chamber of Commerce's challenge of the law that allows Arizona to suspend the license of a company that employs illegal immigrants. The U.S. Supreme Court is hearing arguments Wednesday in a case challenging a law in the southwestern state of Arizona that penalizes employers for hiring illegal immigrants. Under the 2007 law, Arizona can suspend the license of a company found to be employing illegal immigrants. After two violations, the border state can revoke the right of the firm to do business in the state. The U.S. Chamber of Commerce is challenging the law, saying it interferes with a federal immigration law Congress passed in 1986. The Chamber says Arizona has interpreted too broadly the part of the law that allows states to revoke licenses, and created a system in which state authorities enforce their own harsher version of immigration law. Arizona has defended its immigration measures as necessary to combat crime that's been blamed on illegal immigrants, protect its borders, and respond to the influx of people crossing from Mexico illegally. The disputed Arizona law also requires employers to use a federal program called E-Verify to make sure that employees are in the U.S. legally. Under federal rules, the system is merely optional. Earlier this year in Arizona, a measure signed into law by the state's governor sparked a fiery debate and a series of protests. It included a provision - which is now on hold because of legal challenges - that requires police to investigate the immigration status of someone they suspect of being in the U.S. illegally, while the police are enforcing other laws. Also Wednesday, U.S. Senate Democrats will try to advance an immigration measure that would provide a path to legal residency for tens of thousands of young, foreign-born immigrants brought to the U.S. illegally by their parents. Lawmakers in the House of Representatives may also debate the bill, known as the Development, Relief and Education for Alien Minors Act, or DREAM Act. Immigration advocates and the Obama administration support for the measure. .
