City of Sherrill v. Oneida Indian Nation of NY
The Supreme Court ruled that the Oneida Indian Nation could not revive its sovereign immunity from local property taxes simply by repurchasing parcels of its historic reservation on the open market nearly two centuries after the land passed into non-Indian hands.
The decision means the tribe must keep paying property taxes on land it recently bought in the city of Sherrill, and it signals that courts will resist letting tribes reclaim governmental authority over long-settled, non-Indian communities through piecemeal land purchases.
“The Oneidas long ago relinquished the reins of government and cannot regain them through open-market purchases from current titleholders.”
The majority's core holding rejecting the tribe's claim to revived sovereignty.
How it got here: A federal district court ruled the parcels were tax-exempt Indian country and the Second Circuit affirmed; Sherrill asked the Supreme Court to review that decision.
The Case in Depth
What happened
The Oneida Indian Nation once held a 300,000-acre reservation in central New York but sold nearly all of it to the state in the early 1800s. In 1997 and 1998, the tribe's modern successor bought back a few parcels in the city of Sherrill, now home to a gas station, convenience store, and textile facility, and argued the land was exempt from local property taxes because it sat within the old reservation's boundaries.
The question before the Court
Could an Indian tribe buy back pieces of its ancient reservation on the open market and thereby revive its sovereign immunity from local property taxes on those parcels?
The Court's answer
No — the Court ruled that the Oneida Indian Nation could not revive its sovereign immunity from local property taxes just by buying back parcels of its ancient reservation on the open market. Even though the tribe once held aboriginal title to this land, two centuries had passed since it last governed the area, and New York's state and local governments had continuously and openly exercised authority over the now overwhelmingly non-Indian community in the meantime.
The Court relied on equitable doctrines — laches, acquiescence, and impracticability — that block stale claims from disrupting long-settled arrangements, rather than ruling on the tribe's underlying historical rights. It pointed instead to an existing federal process, letting the Secretary of the Interior place land into tax-exempt trust status while weighing local governments' interests, as the proper path for the tribe to pursue.

Why it matters
Local governments in areas with historic Indian reservations can continue collecting property taxes and enforcing zoning and other regulations on land tribes buy back today, even inside old reservation boundaries. Tribes seeking tax-exempt land must instead use the federal process for placing land into trust, giving states and counties a voice in the decision rather than facing sudden, unilateral changes to local governance.
What changes now
The case was reversed and remanded to the Second Circuit for further proceedings consistent with the Court's ruling, meaning the tribe's parcels in Sherrill remain subject to local property taxes. The ruling is a final decision on the merits of the tax-immunity question, though it left open other issues, including whether the tribe's reservation had ever been formally disestablished, and it did not disturb the tribe's earlier damages award against the counties.
What this does not decide
The Court did not decide whether the Oneidas' reservation was ever formally disestablished by Congress, did not disturb the tribe's earlier right to damages for the 1795 land taking, and expressly limited its holding to the tribe's claim of present and future tax immunity over land it recently repurchased — not the tribe's other forms of jurisdiction or rights.
Concurrences and dissents
Concurrence — Justice Souter
Justice Souter joined the majority but wrote separately to clarify that the tribe's long inaction and absence from the land should not be treated merely as a factor limiting an equitable remedy to be decided later. He argued the tribe's inaction is central to the underlying claim of sovereign status itself, not just a remedial afterthought, though he agreed reargument on this point was unnecessary since both sides had already addressed it.
Dissent — Justice Stevens
Justice Stevens argued the majority improperly used equitable doctrines to strip the tribe of tax immunity, a core sovereign right that only Congress, not courts, can revoke. He contended the case was really about a straightforward tax-immunity defense, not equitable relief, and that the tribe bought its land lawfully on the open market without harming any innocent landowners, so equity should favor the tribe rather than New York's settled expectations.
How the Court got there
The legal reasoning, step by step
- The Court distinguished between the tribe's earlier damages claim for the historic wrongful taking of its land, which it had allowed to proceed in a 1985 case, and the very different question of whether the tribe could now claim present and future sovereign immunity from taxation over repurchased land — the Court had explicitly left this equitable question open before.
- The Court applied equitable doctrines long used to limit disruptive remedies: laches (which bars stale claims when one side delayed asserting rights and the other reasonably relied on that inaction), acquiescence (long tolerance of another's exercise of authority over territory can settle the matter), and impracticability (courts avoid remedies that would upend deeply entrenched, changed circumstances).
- Applying these doctrines, the Court found that two centuries of continuous New York state and local governance, the overwhelmingly non-Indian character and development of the area, and the tribe's failure to seek judicial relief against Sherrill or similar local governments until very recently, together created settled expectations that a court should not disturb.
- The Court reasoned that letting the tribe revive sovereignty piecemeal, parcel by parcel, simply by buying land on the open market would create a confusing checkerboard of overlapping state and tribal authority, seriously burdening local governments and neighboring property owners.
- The Court pointed to an existing federal statute letting the Secretary of the Interior place land into trust for tribes, which weighs the interests of state and local governments before removing land from tax rolls, as the proper channel for a tribe seeking tax-exempt status rather than a unilateral court-ordered revival of sovereignty.
