FTX customers aren’t backing down from a class action lawsuit against Sullivan & Cromwell, according to a Monday court filing opposing the law firm’s motion to dismiss.

The retail investors, represented by Adam Moskowitz of the Moskowitz Law Firm in South Florida, filed the initial class action within an ongoing multidistrict litigation in the Southern District of Florida in February. The complaint alleged that Sullivan & Cromwell not only knew of the ongoing fraud at FTX, but aided it over the course of 20 legal matters the law firm performed for FTX before the cryptocurrency exchange’s collapse and subsequent bankruptcy filing.
