US immigration laws ruled illegal

America’s highest court has thrown out key provisions of border state Arizona’s harsh crackdown on immigrants, one of the most divisive domestic issues separating president Barack Obama from his Republican challenger Mitt Romney.

While finding much of the Arizona law unconstitutional, the Supreme Court did say that one part would stand – the portion requiring police to check the status of someone they suspect is not in the United States legally. Even there, though, the justices said the provision could be subject to additional legal challenges.
