There is no end in sight for the class of American Indian plaintiffs seeking billions of dollars from the Interior Department for the mismanagement of oil, timber, gas and other royalties flowing from the lease of Indian lands.

A federal judge in August ruled the class, whose lead plaintiff is represented by Kilpatrick Stockton, is entitled to nearly $456 million from the government. The judge’s award against the Interior Department represents the aggregate amount of funds received into the Indian trust accounts between 1887 and 2007.
