Here is that complaint, filed in the Court of Federal Claims: Goodeagle v. US Complaint

An excerpt:

This is a lawsuit for money damages arising from Defendant’s breach of fiduciary and trust obligations owing to Plaintiffs, Grace M. Goodeagle, Thomas Charles Bear, Edwina Faye Busby, James E. Gilmore, Jean Ann Lambert, Florence Whitecrow Mathews, Ardina Revard Moore, and Fran Wood, and the class they represent, all of whom are enrolled Members of the Quapaw Tribe of Oklahoma (O-Gah-Pah), a federally recognized Indian nation. The claims arise from Defendant’s failure to properly manage amounts due and owing to the Quapaw Tribal members under leases, permits, and agreements and government actions or inactions relating to certain real property, personal property (including chat severed from the surface and mineral estate by mining), mineral rights, as well as other sums due and owing to them by operation of law. These claims also arise from Defendant’s serious and sustained mismanagement of the Quapaw Tribal members’ Individual Indian Money Accounts, trust accounts, and other monetary assets. These claims also arise from Defendant’s similar mismanagement of the natural resources and other assets on Quapaw Tribal members’ trust/restricted lands, including but not limited to the mismanagement arising from federally managed mining activities on Quapaw Tribal members’ land, resulting in the destruction of natural resources and the environment, including the ability of Tribal members to use the land and other resources for grazing or agricultural or any other economically beneficial purpose.

An accounting of Defendant’s historical management of Quapaw trust assets — as set forth in a report known as the Quapaw Analysis — recently was completed and accepted as final by the Office of Historical Trust Accounting of the United States Department of the Interior. That accounting report, the product of a settlement of a previous suit for an equitable accounting, identifies and details Defendant’s mismanagement of numerous sampled Tribal and individual Tribal member trust assets, including but not limited to Defendant’s failure to collect monies due and owing under leases, permits, and agreements for the Quapaw Tribe and for the restricted interest holders of 13 allotments and of the class they represent, the degradation of the natural resources on the land and the environment, and the waste and dissipation of other trust assets, all of which was the result of mismanagement and negligence by the Defendant. The substantive law governing the United States’ trust responsibilities that were breached in this case may be fairly interpreted as mandating monetary compensation for damages sustained as a result of the breach of those duties.
