Governor Concurrence Under IGRA: Why It Can Decide an Off-Reservation Casino

Few phrases carry as much weight in off-reservation tribal gaming as governor concurrence. Under the Indian Gaming Regulatory Act, a tribe seeking to open a casino on land acquired in trust after October 17, 1988 generally needs a state governor's agreement before the project can proceed, unless a statutory exception applies. This explainer describes what governor concurrence is, where it comes from, and why it has become one of the most closely watched steps in the approval process.

Where the requirement comes from

IGRA generally prohibits gaming on lands taken into trust after its enactment in 1988. Section 20 of the Act, codified at 25 U.S.C. 2719, then sets out exceptions. The best known are for lands within or contiguous to a tribe's existing reservation, lands acquired in settlement of a land claim, lands for a newly recognized tribe, and lands restored to a tribe that has regained federal recognition. These are covered in our explainers on Section 20 exceptions and on land into trust and gaming eligibility.

A separate route, commonly called the two-part determination, applies to off-reservation parcels that do not fit an exception. Under it, the Secretary of the Interior must determine, after consulting with the tribe and with appropriate state and local officials, including officials of nearby tribes, that a gaming establishment would be in the best interest of the tribe and its members and would not be detrimental to the surrounding community. Only then does the second part arrive: the governor of the state in which the gaming will occur must concur in the Secretary's determination. Our detailed explainer on the two-part determination walks through the full procedure.

What concurrence means in practice

Concurrence is a gubernatorial decision, not a federal one. The Secretary can make a favorable determination and the project still cannot go forward if the governor declines to concur. The statute does not set out detailed criteria or a deadline for the governor in the way it does for other steps, so the decision is generally treated as a matter of the governor's discretion, informed by state policy, local views and the political context. The result is that two otherwise similar projects can have different outcomes in different states.

The governor's role is also distinct from the separate task of negotiating a Class III compact. Concurrence addresses whether the land may be used for gaming at all; the compact governs which games may be offered and on what terms. A tribe may therefore need both a concurrence and, later, a compact. Our explainers on good-faith compact negotiation and on the full federal approval pathway show where each step sits.

Governor concurrence is a threshold question about the land. A compact is a later question about the games.

Why the requirement matters

Because the two-part determination requires a governor's agreement, it gives states a direct voice in off-reservation gaming that they lack for on-reservation projects. That voice is exercised in an environment that includes competing casinos, host-community politics and, in some states, existing exclusivity arrangements. Our analysis of the historical-connection hurdle and of the 2026 off-reservation wave discuss how those pressures play out in current cases.

The requirement also explains why many tribes pursue other routes first. A restored-lands or initial-reservation exception does not call for a governor's concurrence, so tribes with a plausible claim under those provisions often prefer them. Tribes without such a claim face a process that depends on political agreement as much as on legal merit.

For tribes, the practical consequence is timing. A governor's decision can come years after the tribe has acquired land, completed environmental review and secured a favorable federal determination, and the tribe may have invested substantial resources by then. Elections can change who holds the office, and a concurrence given or withheld by one governor does not necessarily bind a successor in the same way for a later project. Tribal governments and their advisers therefore typically begin outreach to state and local officials early, and they often negotiate community agreements in parallel. Our explainer on municipal services agreements with host communities describes what those agreements commonly contain.

Common misunderstandings

Several misconceptions recur. Concurrence is not required for gaming on a tribe's existing reservation. It is not the same as the compact approval that a governor may sign. And it is not a federal approval; the Secretary's determination is a separate decision that must come first. The process also takes place alongside environmental review, which our explainer on NEPA review for fee-to-trust casino projects covers.

Readers who want to see the requirement in a live case can consult our reporting on the Menominee Kenosha project's federal review, which discusses the concurrence step. For definitions of related terms, see the glossary and the Legal Guide.

In short, governor concurrence is the statutory mechanism that gives a state's chief executive a decisive say over whether an off-reservation tribal casino can proceed under the two-part determination. Anyone assessing a proposed project's prospects should treat it as a distinct political and legal hurdle, separate from the federal trust decision and from later compact negotiations.
