A new Arizona law considered among the nation’s toughest against employers who hire illegal immigrants will go into effect on Jan. 1 after federal judges on Friday refused to block it.

Both a United States district judge in Phoenix and a federal appeals court in San Francisco, ruling on separate lawsuits by business and civil rights groups, declined to stand in the way.

The law calls for suspending the license of an employer found to have knowingly hired an illegal worker, and revocation for a second offense.

How exactly would one prove a business "knowingly" hired an illegal immigrant?

Well if the immigrant doesn't have a Social Security card and is getting paid less than minimum wage... They probably know. :thumbs:

But I thought most of them these days get jobs with stolen or fake SS numbers.

Well I don't know about "most", but at least some, and that makes it a lot harder. But I assume that there are still thousands and thousands of illegals hired knowingly, and cracking down on those employers is still necessary.
