Kevin LaCroix, at his D&O Diary blog, has a tremendous history of the recent filing of subprime litigation, including class actions, many filed under ERISA. While I don’t necessarily agree with each of his interpretations of that history, it’s as good an overview of the subject as a whole that I have seen in any media. Perhaps my primary point of departure from his presentation would concern his view that these cases are very different from other types of class action litigation, such as the stock drop cases, that are often criticized as lawyer-driven suits warranting reform, because these are cases instead being brought by “very large institutions [who are] suing other very large institutions.” Perhaps, and certainly to some extent, but there is also an aspect to at least some of these cases that reflect that the class action bar has, for reasons of legal developments, public sentiment, and the winds of politics, moved towards using ERISA in circumstances where they would have previously used the securities laws, as well as towards the representation of large retirement plans, rather than individuals, as plaintiffs.
