The U.S. Supreme Court has declined to hear the custody case of a Choctaw child who was placed with extended family in Utah under terms of the Indian Child Welfare Act, ending a years’ long effort by opponents to overturn the law designed to keep Indian children in Native American families., the tribe said, in a news release. Without comment, the court refused to hear an appeal of California court decisions that removed a child known as Lexi from a Santa Clarita foster family who had fought the law in an effort to adopt Lexi.
