A federal judge’s unexpected rejection of the settlement in the NFL concussion case earlier this month has drawn praise from lawyers for some of the former football players who allege they’ve been kept in the dark on the details of the deal.

When U.S. District Judge Anita Brody of the Eastern District of Pennsylvania declined to grant preliminary approval of the $760 million agreement, she made clear that she was troubled by the lack of empirical support for the figure and that she was unsure that there would be enough money to cover all of the players with potential claims. Brody ordered the NFL and the co-counsel for the plaintiffs to submit to the court the documentation on which they based the settlement.
