A federal judge has told attorneys with Sonnenschein, Nath & Rosenthal there is no way the firm can represent both an alleged tax fraud conspirator and a cooperating witness for the government.

Southern District of New York Judge William Pauley said that a “clear conflict of interest” exists where one Sonnenschein attorney represents former BDO Seidman partner and now cooperator Adrian Dicker and another represents former BDO Seidman CEO Denis Field.
