The U.S. Attorney’s Office for the Central District of California has filed its first response opposing motions to dismiss several counts of its criminal case against Milberg Weiss and two of its former partners.

The case, brought a year ago, alleges that Milberg Weiss and two of its former partners, Steven Schulman and David Bershad, collected $200 million in attorney fees by paying secret and illegal kickbacks to named plaintiffs.
