(a) Compensation for a loss of an allotment or interest shall be the fair market value of the land interest therein as of the date of tax forfeiture, sale, allotment, mortgage, or other transfer described in section 4(a), 4(b), or 5(c), less any compensation actually received, plus interest compounded annually at 5 per centum from the date of said loss of an allotment or interest until the date of enactment of this Act [Mar. 24, 1986], and at the general rate of interest earned by United States Department of the Interior funds thereafter. A determination of compensation actually received shall be supported by Federal, State, or local public documents filed contemporaneously with the transaction or by clear and convincing evidence. Compensation actually received shall not be subtracted from the fair market value in any instance where an allotment or interest was sold or mortgaged by a full or mixed blood, under the age of eighteen years, or in any instance where there is prima facie evidence that fraud occurred in a sale or mortgage. No compensation for loss of an allotment or interest relating to transfers described in section 4(b) shall be granted to any person or the heirs of such person where such allotment or interest was received pursuant to State court probate proceedings and where also it has been or is determined by the Secretary that such person or heirs were not entitled to inherit the allotment or interest.
“(b) For the purpose of this section, the date of transfer applicable to interests described in section 4(b)(6) shall be the last date on which any interest in the subject allotment was transferred by document of record by any other heir of the allottee; and the date of transfer applicable to allotments described in section 5(c) shall be the selection date. For purposes of this section, the Secretary shall establish the fair market value of various types of land for various years, which shall govern the compensation payable under this section unless a claimant demonstrates that a particular allotment or interest had a value materially different from the value established by the Secretary.
“(c) The Secretary shall provide written notice of the Secretary’s compensation determination to the allottees or heirs entitled thereto. Such notice shall describe the basis for the Secretary’s determination, the applicable time limits for judicial review of the determination, and the process whereby such compensation will be distributed. The Secretary shall proceed to make such heirship determinations as may be necessary to provide the notice required by this section: Provided, That the Secretary shall accept as conclusive evidence of heirship any determination of the courts of the State of Minnesota as provided in section 5(a) of this Act: Provided further, That the Secretary shall give written notice only to those allottees or heirs whose addresses can be ascertained by reasonable and diligent efforts; otherwise such notice shall be given by publication in the Federal Register.
“(d) The Secretary’s administrative determination of the appropriate amount of compensation computed pursuant to the provisions of this Act may be judicially reviewed pursuant to the Administrative Procedure Act [5 U.S.C. 701 et seq.] not later than one hundred and eighty days after the issuance of notice as aforesaid; after such time the Secretary’s determination shall be conclusive and all judicial review shall be barred. Exclusive jurisdiction over any such action is hereby vested in the United States District Court for the District of Minnesota.
“(e) Once a compensation determination has become conclusive according to the provisions of subsection (d), the Secretary shall certify such determination to the Secretary of the Treasury and such conclusive determination shall be treated as a final judgment, award or, compromise settlement under the provisions of title 31, United States Code, section 1304. The Secretary of the Treasury is authorized and directed to pay out of the funds in the Treasury into a separate interest bearing White Earth Settlement Fund account the amount certified by the Secretary of the Interior in each case. The Secretary of the Interior shall then make a diligent effort to locate each allottee or heir; however, if, after two years from the date on which a determination becomes conclusive an allottee or heir cannot be located, the Secretary of the Interior shall declare the amount owing to such allottee or heir forfeited.
“(f) Any and all amounts forfeited pursuant to subsection (e) together with the interest accumulated thereon, pursuant to section 8 shall be transferred annually to the fund established under section 12 for the White Earth Band.
