Immigration Legislation: Supreme Court ruling on Arizona act could shape immigration law

This Supreme Court case precedes the more (in-)famous one of  SB 1070, but it presents the same Constitutional question as to federal precedence over the states in immigration law. 

Supreme Court ruling on Arizona act could shape immigration law - latimes.com: "This week, Obama's top courtroom lawyer will join the U.S. Chamber of Commerce in urging the Supreme Court to strike down an Arizona law that goes after employers who hire illegal workers. The administration also seeks to void a part of the state's law that tells employers they must check the federal government's E-Verify database to make sure their new hires are authorized to work in the United States.

The move sets the stage for a high court ruling on the most disputed issue in immigration law: Can states and cities enforce their own laws against illegal immigrants, or must they wait for federal authorities to act?

The administration found itself in an awkward spot in part because the Legal Arizona Workers Act was signed into law in 2007 by then- Gov. Janet Napolitano." Dec. 6, 2010
