The question in this case is whether, when a tribe collects its own third-party revenue pursuant to 25 U.S.C. § 1641(d)(1), its expenditures of those funds on health care services are eligible for CSC funding from the IHS under the ISDEAA, id. §§ 5325, 5388.
Here are the materials in Cook Inlet Tribal Council v. Mandregan (D.D.C.):
The Navajo Nation Department of Justice seeks outside counsel assistance in pursuing the Navajo Nation’s claims for unpaid contract support costs from P.L. 93-638 contracts entered into with the Indian Health Service (IHS). This would include developing claims for unpaid contract support costs, entering into settlement negotiations with IHS and, if necessary, making recommendations to the Attorney General for litigation of those claims if a negotiated settlement cannot be reached. Qualifications include experience in and knowledge of Federal Indian law, especially the Indian Self-Determination and Education Assistance Act (ISDEAA), P.L. 93-638, as amended, and experience filing claims for payment of contract support costs pursuant to the ISDEAA.
Proposals must be received by email by the Navajo Nation Department of Justice by no later than 5:00 PM MT on September 16, 2016. NO LATE PROPOSALS WILL BE ACCEPTED.

Here are the materials in Navajo Health Foundation – Sage Memorial Hospital, Inc. v. Burwell (D. N.M.):
From the opinion:
Finally, the Court will grant the MSJ on two grounds. First, the Court will deem the Claim denied, because Dayish has not given Sage Hospital a “date certain” by which he will decide the Claim; rather, he conditioned his October 21, 2015, deadline upon Sage Hospital’s cooperation. Second, even if Dayish had given Sage Hospital a date certain by which he will decide the Claim, his proposed fourteen-month period for deciding the Claim is unreasonably long under the CDA.  Accordingly, even if the Court did not deem the Claim already denied, it would order Dayish to approve or deny the Claim by July 25, 2015.
