WASHINGTON (AP) -- The Supreme Court on Monday rejected appeals by American Indians to step into a decade-old lawsuit accusing the government of mismanaging more than $100 billion in oil, gas, timber and other royalties from their lands. The justices declined to disturb an appeals court ruling that removed U.S. District Judge Royce Lamberth from the case. The appeals court said Lamberth, who held successive Democratic and Republican Interior Department secretaries in contempt of court, had lost his objectivity in the case.
