Federal Reversal Withdraws Solicitor Opinion and Shifts Tribal Gaming Dynamics in Oklahoma

The U.S. Department of the Interior formally withdrew Solicitor's Opinion M-37084 on May 22, 2026 through a memorandum issued by Solicitor William L. Doffermyre, and this step reversed a previous legal interpretation from the Biden administration that had briefly backed the United Keetoowah Band of Cherokee Indians in its push to place land into trust for gaming purposes inside the Cherokee Reservation near Tahlequah, Oklahoma.
That withdrawal immediately restored exclusive jurisdiction to the Cherokee Nation over such matters and it halted the UKB's ongoing casino project while it simultaneously removed the legal foundation for a 2025 gaming compact the UKB had reached with the state of Oklahoma.
Background on the Withdrawn Opinion and Tribal Jurisdiction Questions
Solicitor's Opinion M-37084 had emerged during the prior administration as a narrow legal reading that opened a pathway for the UKB to seek trust land status for gaming activities within the historic Cherokee Reservation boundaries, and observers note this created overlapping claims because the Cherokee Nation has long asserted primary treaty-based authority over the same territory.
The opinion itself addressed specific trust land applications and it examined how federal recognition of multiple Cherokee groups intersected with reservation geography, yet the May 22, 2026 memorandum explicitly rescinded that analysis and returned the Department to its earlier stance that treats the Cherokee Nation as the sole tribal entity with jurisdiction in the area.
Immediate Effects on the UKB Casino Project and State Compact
With the opinion withdrawn the UKB's plans to develop a casino on newly acquired trust land came to an abrupt standstill because the Bureau of Indian Affairs could no longer rely on the prior legal support when reviewing trust applications, and this development also placed the 2025 gaming compact between the UKB and Oklahoma in a precarious position since that agreement depended on the federal interpretation now reversed.
State officials have not yet issued formal statements on whether the compact remains active, yet the absence of trust land approval effectively prevents the UKB from moving forward with any gaming operations tied to the agreement, and this leaves both parties to assess next steps under the new federal posture.
Reactions from the United Keetoowah Band and Cherokee Nation

The UKB issued a public statement criticizing the withdrawal and it announced intentions to pursue litigation to challenge the Department of the Interior's action, arguing that the reversal undermines federal recognition of the band's sovereign rights and disrupts economic development initiatives already underway.
In contrast the Cherokee Nation issued a welcoming response that framed the decision as a clear reaffirmation of longstanding treaty rights and historical jurisdiction, and tribal leaders pointed to the withdrawal as consistent with prior legal understandings that recognize the Cherokee Nation's exclusive authority within reservation boundaries.
Both tribes have maintained active communications with federal officials since the May action, yet their positions remain sharply divided on the underlying questions of reservation governance and gaming eligibility.
Broader Context and Developments Through July 2026
As of July 2026 the Department of the Interior has not released additional guidance beyond the May memorandum, and this leaves the UKB's trust land applications in a holding pattern while the Cherokee Nation continues its existing gaming operations without new competition from the disputed site.
Federal courts have not yet scheduled hearings on the anticipated UKB lawsuit, though legal observers expect filings to occur before the end of summer, and any rulings could influence how similar jurisdictional disputes are handled in other regions with multiple federally recognized tribes.
The case also highlights ongoing tensions around how the Indian Gaming Regulatory Act interacts with historical reservation boundaries when more than one tribe claims overlapping interests, and the May 22, 2026 withdrawal has become a reference point in those discussions.
Conclusion
The withdrawal of Solicitor's Opinion M-37084 on May 22, 2026 stands as a pivotal administrative action that realigned federal policy on tribal land and gaming jurisdiction in eastern Oklahoma, and its effects continue to shape the operational landscape for the UKB and the Cherokee Nation well into the summer months.
Both tribes have signaled their intent to defend their respective positions through available legal and administrative channels, which sets the stage for further developments that will likely extend beyond the immediate dispute over the Tahlequah-area project.
