The New Jersey federal court's opinion disagreed with the cases in New York dismissing similar suits. As I understand it, the suits in California are in the discovery stage and the suit against Cooley, which was dismissed, in on appeal to the Sixth Circuit. Brief news story from Law360.
As I've said here before, drawing on my previous career as a plaintiffs-side business tort lawyer, I was surprised that all the suits didn't survive to the discovery stage. But as I understand it, the suits in New York were based upon what wasn't said by the schools while the suit against Cooley was based upon what was said. That may be the dividing line that holds in the long run. I find this USDC opinion out of New Jersey to be the best reasoned opinion yet. The cases out of New York seemed to me to provide the law schools with an exemption from the normal operation of the law (i.e., it seems a bit cozy for the judge to decide to merely lecture law schools on their ethical failing and dismiss them from the suit).
At Tax Prof Blog, Paul Caron has links to the results in some of the prior suits.
