The Supreme Court on Thursday upheld an Arizona law that penalizes businesses for hiring workers in the country illegally, buoying the hopes of supporters of state crackdowns on illegal immigration.
They predicted the ruling would lead to many other states passing laws that require employers to use the federal E-Verify system to check that workers aren't illegal immigrants. And some said the ruling bodes well for the prospects of a much broader and more controversial immigration law in Arizona, known as SB1070, to be found constitutional.
