Background
The federally recognized California Valley Miwok Tribe has never validly completed its initial organization under the Indian Reorganization Act. Competing factions have disputed for decades who may participate in adopting the Tribe’s governing documents. In 2015, Assistant Secretary for Indian Affairs Kevin Washburn identified three eligible groups, including descendants of Rancheria resident Jeff Davis, while leaving possible inclusion of descendants of Miwok Indians listed on a 1929 Calaveras County census to the eligible groups as an internal tribal decision.
Interior initially identified 289 eligible voters, but a later genealogical review concluded that John Jeff—through whom most proposed voters traced their ancestry—was not Jeff Davis’s son. That finding reduced the eligible organizing population to approximately 10 or 11 people. In 2022, Assistant Secretary Bryan Newland revised the eligibility criteria to include descendants of Miwok Indians listed on the 1929 census. Plaintiffs challenged that revision under the Administrative Procedure Act, and the district court granted summary judgment to the government.
The Court’s Holding
The D.C. Circuit affirmed, holding that Newland’s decision was reasonable and reasonably explained and therefore was not arbitrary or capricious. Prior judicial and administrative decisions had consistently contemplated an organizing community much larger than a handful of people. Newland reasonably responded to the corrected genealogy, which otherwise would have excluded more than 96% of those whom Washburn had understood his criteria to cover.
The court also emphasized that Washburn had already said inclusion of the 1929 census descendants might be proper and that members of that group had substantial historical ties to the Sheep Ranch Rancheria, including decades of residence there. The court limited its holding to eligibility to participate in organizing the Tribe; it did not decide who qualifies for tribal membership, which remains for the Tribe to determine. The plaintiffs’ unreasonable-delay claim was abandoned below, and their statute-of-limitations and issue-preclusion arguments were not preserved.
Key Takeaways
- Interior reasonably added descendants of Miwok Indians listed on the 1929 Calaveras County census to the groups eligible to participate in the Tribe’s initial organization.
- The corrected genealogical record, prior decisions contemplating a substantially larger organizing community, and the 1929 descendants’ historical connection to the Rancheria supported the agency’s decision.
- The ruling concerns participation in the organizational process, not the ultimate criteria for tribal membership, and additional appellate theories failed because they were not preserved.
Why It Matters
The decision permits Interior to move forward with an organizational process that includes a broader group of people with documented historical connections to the Tribe and Rancheria, rather than leaving organization to approximately 10 or 11 individuals. That determination will shape the Tribe’s future governance and may affect access to more than $27 million being held for the Tribe in California’s Gambling Revenue Sharing Trust Fund.
The opinion also illustrates the deference afforded to a reasoned agency response when corrected facts undermine a prior administrative decision’s central premise, while preserving the fundamental distinction between federal administration of an initial organizational election and a tribe’s authority to define its own membership.
