Cayuga Nation: Land Claims, Leadership Dispute, and Lawsuits

The Cayuga Nation is a federally recognized sovereign Native American nation based in the Finger Lakes region of central New York, and one of the five original members of the Haudenosaunee (Iroquois) Confederacy. Its 64,015-acre reservation in Seneca and Cayuga counties is recognized under the 1794 Treaty of Canandaigua.¹ For more than two decades, the Nation has been shaped by three overlapping stories: a long and ultimately unsuccessful lawsuit to recover its homeland, a bitter internal fight over who leads it, and an expanding effort to exercise sovereign authority on land it is buying back parcel by parcel.

Where the Reservation Stands Today

The Cayuga homeland lies between the eastern and western shores of Cayuga Lake, with the Seneca Nation to the west and the Onondaga Nation to the east.¹ In February 1789, the Nation and New York State signed a treaty establishing a 64,000-acre reservation. Between 1795 and 1807, those lands were sold to New York, and the 1838 Treaty of Buffalo Creek attempted to remove remaining New York Indians westward.² For roughly two centuries after, the Nation was largely landless and its citizens were scattered.³

The courts have since confirmed that the reservation itself was never legally dissolved. The New York Court of Appeals held in Cayuga Indian Nation of New York v. Gould (2010) that the Treaty of Buffalo Creek did not disestablish the reservation.² The Second Circuit reinforced that conclusion in 2021 in Cayuga Nation v. Tanner, applying the Supreme Court’s McGirt v. Oklahoma framework to find that no Act of Congress has disestablished it.⁴

Since 2002, the Nation has used revenue from its businesses to buy dozens of parcels back within the historical reservation boundaries.³ In March 2023, the Department of the Interior approved the Nation’s application to place roughly 114 acres in Union Springs and Springport into federal trust, reversing a 2020 denial. Before that approval the Nation held no land in trust at all.⁵ The determination was published in the Federal Register on April 4, 2023.⁶

The Cayuga Nation of New York is distinct from the federally recognized Seneca-Cayuga Nation of Oklahoma, which traces its ancestry to groups that migrated to Indian Territory in 1831.⁷

The Land Claim That Collapsed

The Nation’s effort to recover its homeland through money damages became one of the longest-running tribal land claims in American history. It argued in federal court that 64,000 acres had been taken in violation of the federal Non-Intercourse Act, which required congressional approval for tribal land sales. A district court ruled in the Nation’s favor, and a jury trial produced an award the judge raised to roughly $248 million.⁸

That victory did not survive appeal. On June 28, 2005, a divided Second Circuit panel reversed, holding the Cayuga had waited too long to sue. The court relied on the Supreme Court’s decision in City of Sherrill v. Oneida Indian Nation of New York (2005) and applied the doctrine of laches, concluding that the remedies the Nation sought would be too disruptive to non-Indian communities.⁹ U.S. Solicitor General Paul D. Clement filed a brief calling the appellate analysis “deeply flawed” and “fundamentally misguided.” On May 15, 2006, the U.S. Supreme Court declined to hear the appeal without explanation, letting the dismissal stand.⁸ The ruling closed the door on monetary damages and cast doubt on other historic tribal claims across the Northeast.

The Leadership Dispute

The conflict that defines the Nation’s modern era is a deep split over who legitimately governs it. On one side is Clint Halftown, who rose to prominence after a former chief died in 2003 and leads the federally recognized Cayuga Nation Council. On the other is a traditionalist faction of Clan Mothers and Sachem Chiefs, including Sachem Samuel George of the Bear Clan, who argue that under the Great Law of Peace only Clan Mothers may appoint and remove leaders.¹⁰

The Bureau of Indian Affairs entered the dispute more than once. In 2011 it endorsed a resolution to remove Halftown and acknowledged the role of Clan Mothers.¹¹ In December 2016, BIA Eastern Regional Director Bruce Maytubby reversed course, accepting the results of a mail-in “Statement of Support” campaign organized by the Halftown faction as evidence of majority backing. The BIA counted 237 of 392 adult Cayuga citizens supporting the Halftown Council.¹² Acting Assistant Secretary for Indian Affairs Michael Black affirmed that decision in July 2017.¹³ In March 2019, U.S. District Judge Colleen Kollar-Kotelly rejected a federal challenge from the traditional faction, finding the BIA’s reliance on the mail-in survey reasonable.

The traditionalists contend the survey’s methodology was never transparently shared and that BIA involvement amounted to federal interference in internal tribal governance.¹⁰ A separate splinter group, the Unity Council, formed in 2010 after claiming to have removed Halftown and two other council members, and took physical control of several Nation-owned businesses in the years that followed.¹⁴

New York’s highest court declined to resolve the underlying question. In Cayuga Nation v. Campbell (2019), the Court of Appeals held that BIA recognition for federal purposes does not settle questions of tribal law, and that state courts lack jurisdiction over the Nation’s internal affairs.¹⁵ The practical effect is that the Halftown Council remains the sole federally recognized government while opponents have no state-court path to displace it.

Demolitions, Evictions, and Violence

The dispute turned physically destructive before dawn on February 22, 2020. Heavy equipment demolished roughly twelve buildings on Nation-owned land in Seneca Falls, including a longhouse used for ceremonies, a daycare center, and several businesses, under orders from the Halftown Council, which said it acted for “public safety reasons.”¹⁶ Joseph Heath, counsel for the traditionalist faction, called the demolitions “viciously unlawful.”¹⁷ Cayuga Nation Police detained seven people; six were released, and one was charged with methamphetamine possession.

The Seneca County Board of Supervisors met the next day, approved a request for U.S. Marshal involvement, and sought to freeze $287,000 in HUD funding allocated to the Nation. Board chairman Robert Hayssen called the incident “domestic terrorism.”¹⁷ The Seneca County Sheriff and State Police remained neutral, and no criminal charges were brought against the Halftown faction over the property destruction.¹⁸

The confrontations did not end. In August 2022, Nation police demolished a residential property in the Town of Varick under a tribal demolition order, and a clash with the opposing faction led officers to deploy pepper spray.¹⁹ In February 2026, Nation police evicted a family from a home, using tasers and chemical spray after what the Nation described as a “hostile actor” attacking officers.¹⁰

The Halftown administration has pursued a sustained campaign of evictions against residents of Nation-owned housing who stopped paying rent in 2011 as political protest. The Nation treats those occupants as illegal squatters owing roughly $700,000 in rent; traditionalists treat payment as recognition of a government they reject.²⁰ Sixteen eviction proceedings filed in local town courts in 2019 were discontinued after the Court of Appeals ruling that state courts lacked jurisdiction.²¹ The Halftown Council then established its own tribal court in Seneca Falls in 2019 and has issued eviction orders through it; residents refuse to appear, calling the court illegitimate.¹⁰ In late 2024, after a state judge issued a temporary restraining order blocking two Seneca Falls evictions, the Nation moved to federal court; Judge Wolford called the state order “procedurally unorthodox,” and the state judge then vacated it.²²

Current Lawsuits

The Nation is pressing several active federal cases that together map its sovereignty strategy.

911 Access

In July 2024, the Nation and Clint Halftown sued Seneca County, Cayuga County, and the director of New York’s Office of Interoperable and Emergency Communications, alleging the counties denied the Nation’s 22-member police department access to the E-911 dispatch system while providing that access to other public safety agencies. The complaint pointed to a delayed response to an April 2023 house fire and a 2024 domestic dispute.²³ In September 2025, Judge Meredith Vacca denied a motion to dismiss, finding the Nation had plausibly alleged the denial was based on the department being an Indian nation’s agency.²⁴ In March 2026, the court denied a second round of dismissal motions and cleared the case for discovery.²⁵

State Lottery on Reservation Land

In 2024, the Nation sued the New York State Gaming Commission and its commissioners, alleging the state operates lottery vending machines and licensed a mobile lottery courier (JackPocket Inc.) on reservation land without complying with the Indian Gaming Regulatory Act.²⁶ In March 2025, the court dismissed the Commission itself on sovereign immunity grounds but allowed claims against the commissioners to continue. In July 2025, the court denied a renewed motion to dismiss, holding that although IGRA creates no private right of action, the Nation may proceed under federal equity jurisdiction.²⁷

Caesars Sportsbook

In June 2026, the Nation sued American Wagering, Inc., operator of Caesars Sportsbook, in the Northern District of New York, alleging illegal mobile sports betting within reservation boundaries without a tribal-state compact or compliance with tribal gaming regulations. The complaint also brings a Lanham Act claim over marketing that described the sportsbook as “lawfully available throughout New York” without disclosing restrictions on tribal land.²⁸ The initial conference was set for September 2026.²⁹

DOJ Recognition

The Nation also sued the U.S. Department of Justice after the U.S. Attorney for the Western District of New York refused to meet with the Halftown-led council, citing the leadership dispute. The case settled in mid-2024, with the DOJ agreeing to defer to Interior’s recognition of the Halftown Council and to maintain liaison communication exclusively through that leadership. The dismissal was without prejudice, so the Nation may revive the suit if the agreement is not honored.³⁰

Governance, Police, and Businesses

The Halftown Council governs with representatives from the Nation’s five matrilineal clans: Bear, Heron, Snipe, Turtle, and Wolf.¹ The Nation established a professional police force in 2018, reaffirmed by the BIA in 2019. In 2024, the FBI issued an Originating Agency Identification number to the Cayuga Nation Police Department, giving it access to national criminal justice databases.³¹ That access followed a 2022 federal ruling in which Judge Royce Lamberth found the FBI’s initial denial “arbitrary and capricious” under the Tribal Law and Order Act.³²

The Nation runs several enterprises. LakeSide Entertainment, opened in 2004, offers Class II bingo-based gaming machines in Union Springs and Seneca Falls under the Cayuga Nation Gaming Commission and the National Indian Gaming Commission.³³ Other businesses include LakeSide Trading convenience stores, Sweet Grass Dispensary cannabis shops (opened 2021), Gakwiyo Garden, LakeView Cattle, and Great Swamp Enterprises.³⁴ The Nation does not run a casino: it has not adopted a Class III gaming ordinance or entered into a tribal-state compact with New York, both required under federal law for casino-style gambling.²⁶

In March 2025, the Nation donated $60,000 to the Union Springs Hose Company for a rescue hovercraft. In April 2026, the Nation announced it had regained possession of a residential property in Seneca Falls after what it described as a 15-year effort to restore housing sovereignty on its land.³⁵
