At least one defendant being sued by the Rothstein Rosenfeldt Adler bankruptcy trustee in the collapse of Scott Rothstein’s fraud is seizing on an order by U.S. District Judge James Cohn to try to stall an action against him.

Cohn ruled the federal government wins the fight for control of real estate and other assets seized in the former law firm chairman’s $1.2 billion Ponzi scheme. The judge decided Friday that the law firm’s bankruptcy trustee can claim only monies that can be traced to RRA bank accounts — even though the law firm was the primary vehicle for Rothstein’s fraud.
