Atkinson Trading Co. v. Shirley
The Supreme Court ruled that the Navajo Nation could not impose its hotel occupancy tax on guests of a privately owned trading post, because the land the hotel sits on is owned outright by non-Indians rather than by the tribe.
The decision confirms that tribes generally cannot tax or otherwise exercise civil authority over non-members on land within a reservation that is not tribally owned, unless a narrow exception applies — reinforcing sharp limits on tribal government power over outsiders and their property.
How it got here: The Navajo Tax Commission and Navajo Supreme Court upheld the tax; a federal district court and a divided Tenth Circuit panel affirmed, and the Supreme Court agreed to review.
The Case in Depth
What happened
A trading post near Cameron, Arizona, built in 1916 on land purchased directly from the federal government, ended up inside the Navajo Nation Reservation after the reservation's boundaries were expanded in 1934. The land remained privately owned, non-Indian "fee land." In 1992 the Navajo Nation imposed an 8% tax on hotel rooms within the reservation, which the trading post's owner had to collect from its guests and remit to the tribe.
The question before the Court
Could the Navajo Nation collect an 8% hotel tax from guests staying at a privately-owned trading post located on non-Indian-owned land inside the reservation?
Why it matters
Businesses and individuals who own land inside reservation boundaries but hold it as private, non-tribal property gain clearer protection from tribal taxes and regulations. Tribal governments, in turn, cannot rely on generalized services like police or fire protection, or on a business's proximity to tribal land, to justify taxing outsiders — they must show a specific consensual relationship or a serious threat to tribal welfare.
What changes now
This is a final merits decision, not subject to further proceedings beyond the reversal itself. The Navajo Nation cannot enforce its hotel occupancy tax against the Cameron Trading Post's guests going forward. The ruling stands as guidance for how courts assess tribal civil authority — including taxation — over non-members on privately owned land within other reservations nationwide.
What this does not decide
The Court did not decide whether the Navajo Nation could tax activities specifically tied to the trading post's status as a federally licensed "Indian trader," since that issue wasn't before it. It also left open whether a tribe could charge a specific fee for an actual service rendered, as opposed to a general tax.
Concurrences and dissents
Concurrence — Justice Souter
Justice Souter, joined by Justices Kennedy and Thomas, wrote separately to emphasize that Montana v. United States is the true source of the governing rule, and that whether land is tribal or non-Indian fee land matters mainly because it affects whether the facts needed to trigger one of Montana's exceptions are likely to be present. He stressed that Montana's general rule against tribal authority over non-members applies as the starting point regardless of the land's ownership status.
How the Court got there
The legal reasoning, step by step
- The Court applied its rule from Montana v. United States, which holds that tribes generally lack civil authority — including the power to tax — over non-members on land within a reservation that is privately owned by non-Indians, unless one of two narrow exceptions applies.
- The first Montana exception allows tribal authority when a non-member has entered a consensual relationship with the tribe, such as through a contract or lease, that has a direct connection to what's being taxed or regulated.
- The Court rejected the argument that simply benefiting from general tribal services like police, fire, or medical response created the kind of consensual relationship required, reasoning that virtually every property within a reservation benefits from such services and accepting this argument would erase the rule's limits entirely.
- The Court also rejected the argument that the hotel owner's status as a federally licensed 'Indian trader' created the needed connection, because that licensing relationship had no direct link to the hotel tax itself.
- Applying the second Montana exception, which permits tribal authority when non-member conduct seriously threatens the tribe's political integrity, economic security, or welfare, the Court found the hotel's operation on nearby private land posed no such threat.
- Because neither exception was satisfied, the presumption that tribes lack authority over non-members on non-Indian land controlled, and the Navajo Nation's tax on the trading post's guests could not stand.
Doctrinal impact
Cases affected by this decision
Reaffirms Montana v. United States (450 U.S. 544)
The Court applies Montana's general rule and its two exceptions directly to tribal taxation of non-members.
Limits Merrion v. Jicarilla Apache Tribe (455 U.S. 130)
The Court narrows Merrion's broader language, confining tribal taxing power to activity occurring on tribal land.
Reaffirms Strate v. A-1 Contractors (520 U.S. 438)
The Court relies on Strate's application of Montana's framework to non-Indian fee land within reservations.
