NEW YORK — A judge has awarded law firms Boies, Schiller & Flexner; Susman Godfrey; and Hausfeld a fraction of the $15 million in attorney fees and costs they were seeking for winning a jury verdict in a price-fixing case against Chinese vitamin C manufacturers.

In a ruling issued on Dec. 30, U.S. District Judge Brian Cogan granted the firms $4.1 million in attorney fees and no costs. Cogan credited them for the “high quality” of their work, but he determined that all of the lawyers’ costs and a large part of their fees had already been covered by earlier settlements with co-defendants.
