South Dakota v. United States Department of the Interior
Facts
The Yankton Sioux Tribe's Business and Claims Committee passed a resolution requesting that the BIA take a 39.9-acre parcel known as the Wagner Heights Addition into trust for housing purposes. After the Superintendent approved the acquisition, Plaintiffs appealed, and the Regional Director sought and relied on 23 additional documents that were not provided to Plaintiffs before her decision affirming the trust acquisition. Plaintiffs later received fuller versions of the administrative record during the IBIA appeal, and the IBIA held that the Regional Director had clearly erred by not disclosing the supplemental materials but deemed the error harmless. Plaintiffs then challenged the trust acquisition on constitutional, procedural, and APA grounds in federal district court.
Issue
Whether the Department of the Interior's trust-acquisition decision must be set aside because the Regional Director relied on undisclosed supplemental documents, and whether Plaintiffs' additional constitutional, tribal-authority, and bias challenges to the trust acquisition succeed. The case also asked whether the IBIA's later review cured the Regional Director's procedural error.
Rule
A party in an administrative proceeding is entitled to know the factual material on which the agency relies and to have an opportunity to rebut it. Under 25 C.F.R. § 2.21(b), when the official deciding an appeal considers documents or information not contained in the record on appeal, all interested parties must be notified and given at least 10 days to comment before the appeal is decided. Although harmless-error review applies to agency action, an error is not harmless when the procedural violation prevents a party from presenting colorable arguments to the official who actually exercises discretionary decision-making authority.
