Calling all identity thief peeps....
The question would then become whether the bank's identity verification procedures satisfy that burden. I think it would be a difficult endeavor, but it would be good to see it tested.
They absolutely should have known it was wrong -- their business is lending money to people! If their procedure is insufficient, they should have fixed this.
I would love to see the banks sued for libel, a massive class action suit. There are real monetery damages it one could put a number on, and the difference between a bad and a good 30 year mortgage will be a big number.

In this case, maybe you could have a shot by arguing that since the bureaus know that like half the population's information was stolen, they are acting with reckless disregard for whether their statements are true if they don't now do additional investigation to confirm the identity of the subject of their statements in order to mitigate the effects of the breach.
If someone steals Alice's car and commits a hit-and-run, she will be inconvenienced when the cops show up at her door, but the person who reports her plates won't be committing slander.
