There are not enough lawyers in the world to sort out the Madoff mess.

From Mark Gimein:

Thanks to the Bayou court decisions, however, the moment Madoff was revealed as a fraud, any money that these funds-of-funds would have managed to take back would become gains that have to be given back to be redistributed among all the losers in the Madoff scheme. Now, this sounds bad enough, but ... again, there's more. There's no time limit on the gains they'd have to give back, so any fund that outed Madoff could be on the hook for any profits it had gained from its Madoff investments for years back. So, as my fund-manager friend puts it, “The question people have to ask is not, 'Do I have money in a fund that has exposure to Madoff now?' but, 'Do I have money in a fund that that has ever invested with Madoff?' ”

At this point, the complexity of the situation should be clear. But maybe not the whole potential for absurdity. Imagine that Rich Folks Capital Management—RFCM—placed its money with Madoff 10 years ago and then decided, five years ago, that something didn't feel right and pulled it out. Well, now RFCM is on the hook for any of its gains from the time before the fraud was discovered. But what happens if the people who'd invested with RFCM 10 years ago aren't the same as the people who invest with it now? Tough noogies. RFCM's current investors are probably responsible for paying back gains in the RFCM fund that they never even saw. Or, possibly, RFCM needs to go after its own former investors. No one's really sure.

From the statement by SEC Chairman Christopher Cox on why the SEC never pursued allegations of funny business made against Madoff:

The Commission has learned that credible and specific allegations regarding Mr. Madoff’s financial wrongdoing, going back to at least 1999, were repeatedly brought to the attention of SEC staff, but were never recommended to the Commission for action. I am gravely concerned by the apparent multiple failures over at least a decade to thoroughly investigate these allegations or at any point to seek formal authority to pursue them.

In response, after consultation with the Commission, I have directed a full and immediate review of the past allegations regarding Mr. Madoff and his firm and the reasons they were not found credible, to be led by the SEC's Inspector General. The review will also cover the internal policies at the SEC governing when allegations such as those in this case should be raised to the Commission level, whether those policies were followed, and whether improvements to those policies are necessary. The investigation should also include all staff contact and relationships with the Madoff family and firm, and their impact, if any, on decisions by staff regarding the firm.
