Arizona StateIn a forceful decision that has broad implications for immigration enforcement at the state level, the United States Supreme Court today upheld the Arizona Legal Workers Act. Passed in 2007, the Act has two major components: (1) it requires Arizona employers to use the federal E-Verify system; and (2) it allows Arizona to suspend and/or revoke the business licenses of employers who knowingly hire illegal aliens. The Chamber of Commerce filed a lawsuit in 2007 seeking to strike down the Arizona law, arguing that both provisions were preempted by federal law. However, in today's 5-3 decision in Chamber of Commerce v. Whiting, 563 U.S. __ (2011), the Supreme Court rejected each one of the Chamber's arguments and held that Arizona's law is constitutional.
In the majority opinion, the Court unmistakably concluded that the enforcement scheme of the Arizona Legal Workers Act is expressly permitted by federal statute and furthers Congressional intent that our immigration laws be enforced. "Arizona's procedures simply implement the sanctions that Congress expressly allowed Arizona to pursue through licensing laws," Chief Justice John Roberts wrote. "Arizona went the extra mile in ensuring that its law closely tracks IRCA's provisions [the 1986 federal immigration law] in all material aspects." The Court further rejected the Chamber's argument that the Arizona licensing scheme was preempted as having "no basis in law, fact, or logic . . ."

Dan Stein, President of the Federation for American Immigration Reform (FAIR) said, "Today's decision once and for all clarifies that states may require employers to use E-Verify and allows them to sanction employers if they knowingly hire illegal aliens. With this opinion, the Supreme Court has dealt a game-changing blow to special interests that have misused federal preemption claims to impede meaningful immigration enforcement at the local level."
"The court decision affirms our belief that federal law does not preclude immigration enforcement by states and localities, and that immigration enforcement should be a collaborative effort in which states and localities work together in the enforcement of federal immigration laws," Stein continued. "The only thing this decision 'pre-empted' was the U.S. Chamber of Commerce's strong-armed tactics to intimidate local lawmakers from trying to protect their state's legal workers."
FAIR and the Immigration Reform Law Institute are proud to have shaped this landmark legislation. Other states considering mandatory E-Verify laws now have a green light to proceed and can do so with the confidence that they are working within a legal framework on behalf of their citizens-Illegal Immigration Statistics http://www.illegalimmigrationstatistics.org/supreme-court-finds-no-federal-conflict-with-arizona-laws-protecting-legal-workers/
There has been much debate over whether Arizona was being unfair or stereotyping by setting in place the law that people must be able to prove they are citizens.  There has been alot of debate over this, and backlash from many democrats, however the Supreme Court upheld Arizona's law saying it was constitutional to allow them to check for ID's etc.
