A federal appeals court has upheld a settlement in a disputed class action lawsuit over federal mismanagement of Native American land trusts dating back to the 19th century. Under the deal, the Interior Department would pay $3.4 billion to settle claims by more than 300,000 Native Americans for unpaid royalties on seized lands. The settlement is a fraction of the estimated $176 billion Native Americans have maintained they are owed. Kimberly Craven, a class member in the case, had brought the court challenge, claiming the settlement was insufficient. But on Tuesday, a three-judge panel of the U.S. Court of Appeals rejected Craven’s effort and upheld the agreement.
