The Affordable Care Act indeed survived its legal challenge, despite Chief Justice John Robert's bit of creative writing to make the law "constitutional." But that doesn't mean it is a matter of settled law.

At least, that's the way one federal judge sees it. As reported by Britain's Daily Mail:

The Affordable Care Act forbids the federal government from enforcing the law in any state that opted out of setting up its own health care exchange, according to a group of small businesses whose lawsuit got a key hearing Monday in federal court.
