No, not really.
An attorney did some due diligence and realized that CAE, effectively, is dead. There's nothing to get, and it's unlikely they'll be back. Sorry for that, Cadets alums.
So who can they add to the suit who's still alive, since the original suit named a bunch of dead organizations?....oh yeah! Drum Corps International, who had no real or implied role to play in vetting, hiring, or managing staff at the Garfield Cadets in the 1980s, but is still alive and unlike the Garfield/YEA/CAE Cadets, has a pulse and checking account.
At the DCI level, this is a nuisance lawsuit, and they'll likely be bumped from it soon, as well they should.
