Steven Seagal is now suing Loeb & Loeb over the Julius Nasso incident. Loeb & Loeb has already won a determination that any legal malpractice case has to be arbitrated; this arbitration provision is found in its retainer agreement, and in the Nasso v. Loeb & Loeb case, got the AD to uphold the arbitration agreement in the face of a public policy argument.
Prediction: this case too will go to arbitration.
