Seneca Territories — Phase 1 Research Report
Prepared by Golden Eagle Studios LLC | Golden Eagle Studios LLC | Research cutoff: October 14, 2026, America/New_York
1. Executive Conclusions
Cattaraugus Territory is protected Seneca reservation land governed by the Nation’s constitutional government and laws, federal treaties and statutes, and those New York laws that validly apply. Its preservation rests principally on the 1794 Canandaigua treaty, the 1797 Big Tree reservation of land, and the 1842 Buffalo Creek compromise. A county line, highway, assessment entry, or mailing address does not by itself determine sovereign jurisdiction or extinguish protected title. [S02] [S03] [S05] [S30] [S33]
The present Buffalo Creek casino tract has a different legal history from Cattaraugus. The Nation acquired the approximately nine-acre tract in 2005 through the Seneca Nation Settlement Act of 1990 (“SNSA”) process. The Second Circuit upheld its restricted-fee status, its status as a dependent Indian community, and its qualification for gaming under the authorities litigated in Citizens Against Casino Gambling in Erie County v. Chaudhuri, 802 F.3d 267 (2d Cir. 2015). This holding does not establish that every later Nation or affiliate purchase in Buffalo has the same status. [S17] [S19]
The parcel investigation verified 15 downtown or nearby assessment records naming the Nation or its gaming affiliate, a separate 212 Ohio Street acquisition lead, and one out-of-scope Nation property at 265 Skillen Street. County GIS polygons were matched to all 17 SBLs. These are verified assessment and mapping records, not certified title opinions. Recorded deed images and federal tract exhibits were not obtained; the exact crosswalk between the judicially recognized casino tract and today’s individual SBLs remains unresolved. [S21] [S22] [S23]
The most urgent current issue is 5 Miami Street. An October 8, 2026 federal complaint challenges a February 14, 2023 DOI restricted-fee designation. The City also announced a separate state action concerning the proposed gas station/truck-stop development. The Nation asserts sovereign authority over the site. The complaint, City announcements, and Nation position were inspected; no verified merits ruling, vacatur, or injunction is established by the public record assembled here. The land’s status must therefore be presented as an existing designation reported in a filed pleading and currently challenged, with the original decision and exhibits still required. [S24] [S25] [S26] [S27]
There is no universal “tax-free territory” rule. Protected land, an individual’s income, a tribal government’s income, a corporation’s income, and a nonmember’s retail purchase raise different questions. Perkins v. Commissioner rejects an individual federal income-tax exemption for gravel income under the Canandaigua and 1842 treaties. New York’s sales, cigarette, and fuel rules distinguish qualified members from nonmembers and tax liability from collection obligations. [S46] [S49] [S50] [S51] [S52] [S53]
Two current-law developments matter: the Nation published a constitution effective March 24, 2026, and New York amended its Seneca law-enforcement provisions in 2026. Federal and state proposals to change jurisdiction remain proposals in the sources reviewed; they are not treated as an enacted repeal of 25 U.S.C. § 232. [S12] [S40] [S42] [S43] [S44] [S45]
2. Scope, Method, and Evidence Standards
This report completes the authorized public-source Phase 1: history, treaty interpretation, government, Cattaraugus tenure and boundaries, relevant Buffalo holdings, settlement legislation, jurisdiction, and taxation. It does not certify title, select a transaction structure, underwrite a project, or provide a comprehensive review of gaming, environmental, building, lending, or securities requirements. The scope assumption is the casino area and related downtown/nearby Seneca holdings, with historical Buffalo Creek geography kept separate.
The companion workbook contains six registers: Treaties, Buffalo Parcels, Jurisdiction, Taxes, Sources, and Open Issues. Source IDs in this report link to the underlying authorities and match the workbook. The map exhibit reproduces official Nation planning maps and an archival map, and adds a clearly labeled county tax-parcel reference map. All deliverables use the same parcel IDs and evidence distinctions.
“Verified” means the specified source was inspected and supports the stated proposition. A pleading establishes what a party alleges, not that its allegations are true. A statute or published opinion establishes legal text or a holding, subject to its scope and subsequent law. An assessment roll establishes administrative data at its effective date, not present recorded title. “Unknown” means the relevant evidence was not obtained. Inferences and working baselines are identified rather than converted into findings.
Research used original treaty-text transcriptions, Statutes at Large, current code and agency pages, published court opinions, the Nation’s current constitution and historical accounts, City assessment data, and county GIS. Public subsequent-history and amendment searches were performed; no comprehensive commercial citator or complete paid docket review was available. No paid deed images, account purchases, outreach, or counsel engagement occurred. Access dates appear in the source register. The cutoff is October 14, 2026; later docket or legislative developments require refresh.
The City’s 2026 assessment dataset reports row updates on June 11, 2026 and publication on September 11, 2026. The search screened 108 owner-name matches containing “Seneca,” isolated 16 Nation/gaming records including Skillen Street, and separately investigated 212 Ohio. Holdings under affiliate names without “Seneca,” unrecorded changes, and later closings may be missed. [S21]
3. Historical Development
3.1 Seneca Homeland, War, and Preemption
The Seneca Nation’s historical account places its homeland in western New York and describes its role as the western door of the Haudenosaunee Confederacy. The Confederacy, the present Seneca Nation of Indians, the Tonawanda Seneca Nation, individual Seneca members, and commercial enterprises are related but legally distinct. This report does not attribute one government’s authority or property to another. [S10] [S06] [S12]
The Revolutionary War and its aftermath reshaped the diplomatic and territorial relationship. The October 22, 1784 Fort Stanwix treaty imposed peace and boundary provisions on the Six Nations; its terms included hostages and relinquishment of western claims. It is a Confederation-era federal treaty, not a modern county boundary instrument. Later treaty recognition and conveyances must be read with it. The separate congressional approval record was not independently retrieved. [S01]
Colonial and state claims to jurisdiction and the right of preemption did not amount to possession of Seneca land. The preemption chain described in the Big Tree instrument and Fellows v. Blacksmith traces the New York–Massachusetts settlement and later private interests. Preemption meant a preferential right to acquire Native title through a legally effective transaction; it was not itself the extinguishment of Seneca title. This distinction explains why land-company rights and actual Seneca possession could coexist. [S03] [S07]
3.2 Canandaigua and Big Tree
The November 11, 1794 Canandaigua treaty, proclaimed January 21, 1795, acknowledged Seneca land and continued use and enjoyment. Article III sets out the Seneca boundary; Articles IV–V address the reciprocal territorial relationship and passage; Article VI provides an annual payment of $4,500 for the Six Nations. The treaty remains a central source of the Nation’s relationship with the United States, but its general protections must be applied through the particular issue and later law. [S02]
The September 15, 1797 Big Tree transaction ceded a large area to Robert Morris while excepting enumerated reservations, including Cattaraugus and Buffalo Creek, for a $100,000 investment arrangement. Although often called a treaty, the inspected collection identifies it as an agreement, not a Senate-ratified treaty. The federal supervisory certifications and the private conveyance should not be collapsed into a single legal category. The historical exceptions are essential title evidence, but cannot be converted directly into current tax-lot boundaries. [S03]
The 1826 Cattaraugus conveyance later produced Seneca Nation v. Christy, 162 U.S. 283. The Supreme Court disposed of that case on an independent state-law ground concerning the action’s timeliness; it did not issue a merits holding validating every aspect of the land sale under federal law. A complete chain of surveys, deeds, and the disputed conveyance remains outside the records obtained. [S09]
3.3 Removal, Contested Consent, and the 1842 Compromise
The January 15, 1838 Buffalo Creek treaty, amended by the Senate on June 11, 1838 and proclaimed April 4, 1840, formed part of a removal arrangement involving New York Indian nations. Its annexed Seneca conveyance to Ogden and Fellows purported to dispose of Buffalo Creek, Cattaraugus, Allegany, and Tonawanda. The Nation’s historical account describes manipulated consent and the threatened loss of its remaining homeland. A ratified instrument’s existence does not settle the historical controversy over how consent was obtained. [S04] [S11]
The May 20, 1842 agreement, proclaimed August 26, 1842, incorporated a replacement indenture. Article I restored the prior rights and title in Cattaraugus and Allegany, subject to the reserved preemption interests; Article II confirmed the Buffalo Creek and Tonawanda disposition. Article VII rescinded inconsistent parts of the earlier indenture. Article IX sought federal protection of retained land from taxes until sale and relinquishment of possession. The federal assent and subsequent cases are important to its legal operation. [S05]
Buffalo Creek’s historical reservation was consequently lost through this sequence, while Cattaraugus and Allegany were preserved. The 1844 Emslie map reproduced in the exhibits shows part of the historical Buffalo Creek land divided into sale lots. It is evidence of historical disposition, not a map of today’s Buffalo Creek Territory. [S05] [S59]
Tonawanda followed a separate course. Fellows v. Blacksmith, 60 U.S. 366, rejected private forcible removal under the treaties. The November 5, 1857 Tonawanda treaty, ratified June 4, 1858 and proclaimed March 31, 1859, authorized repurchase arrangements. It prevents a misleading account that all Tonawanda land was permanently lost or that the present Tonawanda government is the same government as the Seneca Nation’s elective constitutional government. [S06] [S07]
3.4 Constitutional Government and Modern Reacquisition
The Seneca Nation established its elective constitutional government in 1848; the published constitution has since been amended. This history exists alongside continuing Haudenosaunee traditions and distinct Tonawanda governance. Present legal powers must be taken from the operative constitution and laws, rather than historical descriptions alone. [S10] [S12]
The 1990 settlement legislation arose from inequities and renewal disputes concerning long-term leases at Salamanca and the congressional villages on Allegany. It created a modern acquisition mechanism subsequently used in Buffalo. Reacquisition under that statute has a different legal basis from an assertion that all historical Buffalo Creek land automatically returned to territorial status. [S17] [S19]
4. Treaty Rules and Present Interpretation
The Treaties register identifies execution, ratification/proclamation evidence, parties, legal character, territory, operative provisions, and unresolved records for six historical instruments plus the 1990 statute. Standalone Senate journals and original signed instruments were not obtained for every treaty; the inspected published texts and proclamation information are identified without claiming archival completeness.
The central land-protection chain is Canandaigua’s recognition, Big Tree’s retained reservations, and the 1842 preservation of Cattaraugus and Allegany. The New York Indians, 72 U.S. 761, held that state taxation could not defeat protected reservation possession. This is a land-tax principle, not a general immunity for every activity conducted by every person on the land. [S02] [S03] [S05] [S08]
Article IX of the incorporated 1842 indenture is frequently described as a tax exemption. Its subject is the retained land and possession. Perkins v. Commissioner, 970 F.3d 148, examined the Canandaigua and 1842 texts and rejected an individual member’s claimed exemption for gravel-sale income. The land’s protected status and the member’s taxable income could coexist. The report therefore rejects a blanket exemption for wages, business receipts, or retail transactions based solely on Article IX. [S46, slip op. pp. 13–26]
For title and encumbrances, 25 U.S.C. § 177 generally restricts purchases, grants, leases, and other conveyances of tribal land unless federally authorized. The exact authorization for a proposed lease, assignment, mortgage, or easement must be established. An instrument recorded in Erie County does not by that fact eliminate federal restrictions or prove the grantor held the interest purportedly transferred. [S31]
5. Current Seneca Government and Land Administration
5.1 Operative Constitutional Structure
The current inspected constitution is effective March 24, 2026. Legislative power rests in a 16-member Council, eight Councillors elected from Cattaraugus and eight from Allegany, serving staggered four-year terms. Ten constitute a quorum and ten affirmative votes are required for appropriations. The President exercises executive power and may veto appropriations measures; twelve Council votes are required for the specified override. Council lawmaking authority is stated in Section XIII. [S12, §§ I–III, XIII]
Section IV establishes one Court of Appeals, two Peacemakers Courts, and two Surrogates Courts, with one of each local court at Cattaraugus and Allegany. The appellate court has six judges, with three hearing an appeal. Each Peacemakers Court has three judges and a two-judge quorum; each Surrogates Court now has three judges, with one able to act. Judicial training is required before office and annually. A further appeal to Council requires permission from at least seven Councillors. [S12, § IV]
The constitution retains the default two-year terms for officers not otherwise provided for; it includes residency requirements for terms beginning in November 2026 and a three-consecutive-term limit with a stated transition rule. The published referendum account differs from the constitution in transition wording and contains apparent tally transcription issues. The operative published constitution is used here; a certified text should control any individual eligibility determination. The older judicial webpage’s single-Surrogate description is stale. [S12, § IX] [S13] [S64]
5.2 Land Administration and Limits of Public Records
The Nation’s Maps & Boundaries department maintains land, survey, and boundary records. This is a necessary source for member interests, assignments, surveys, and the exact current territorial boundary. Public county assessment and GIS systems are useful locators but are not substitutes for Nation records or federal land-status documentation. [S14]
The complete current Nation land, leasing, building, environmental, business-licensing, and tax codes were not obtained. The constitution identifies government authority; it does not by itself supply every substantive development rule. No conclusion is made that a proposed development needs only a Council resolution or is exempt from every state or federal permit. These are defined Phase 2 confirmation items, not omitted questions.
6. Cattaraugus Territory: Boundaries, Tenure, and Access
6.1 Geography and Boundary Evidence
The Nation’s planning map depicts Cattaraugus Territory extending along Cattaraugus Creek from the Lake Erie area near Irving toward Gowanda, across Erie, Chautauqua, and Cattaraugus counties. Exhibit 1 reproduces the Nation map dated October 14, 2020 as included in the June 2024 transportation plan. It is an authoritative planning depiction, not a certified legal survey. [S15, printed p. 5]
Published acreage is inconsistent: the 1842 instrument estimates 21,680 acres for Cattaraugus, the 2024 transportation plan describes 22,013 acres, and the EPA-hosted jurisdictional submission states 22,060.8 acres. These figures have different dates and purposes and may reflect different measurement or inclusion conventions. They are not averaged or treated as interchangeable. A current legal description, boundary survey, and later acquisition records are needed for a transaction-level area. [S05] [S15] [S16]
County boundaries and surrounding municipalities describe geography and public administration; they do not establish the full reach of state, local, or Nation powers. Similarly, a right-of-way does not automatically remove a corridor from Indian country: 18 U.S.C. § 1151 expressly includes rights-of-way through reservations. [S30]
6.2 Separate the Interests Before Evaluating a Deal
Nation title, an enrolled member’s possessory assignment, a leasehold, improvements, minerals, and an access easement are separate interests. Perkins describes the Nation’s land ownership and member possessory interests in the Allegany record, including the distinction between surface possession and Nation-owned gravel. It is useful evidence of Seneca tenure, but does not certify a particular Cattaraugus assignment or establish that every current land rule is identical. [S46, slip op. pp. 5–7]
A member or tenant cannot be assumed to hold conventional fee title merely because a property is described as “owned” in conversation or a local record. For financing, the actual collateral may be a leasehold or improvements, subject to Nation consent and federal restrictions. No conclusion that a conventional foreclosure can reach Nation fee title is supported by this record. The required instruments are the Nation assignment or deed, lease, survey, probate orders if applicable, improvement ownership evidence, and applicable approvals. [S14] [S31] [S33]
The historic 1875 and 1890 federal lease statutes, expressly incorporated into the 1990 Act’s definition of covered leases, form part of the leasing framework. The 1890 Act authorized renewals up to 99 years for specified village leases, except railroad leases; its geographic and statutory conditions matter. Section 5 of the 1990 Act addresses approval and negotiation responsibilities in its settlement context. These provisions should not be generalized into a rule that every new Cattaraugus lease, of any land for any purpose, needs no further legal analysis. [S17, §§ 3–5] [S66]
6.3 Roads and the Thruway Dispute
Federal restrictions and the rights-of-way framework in 25 C.F.R. Part 169 must be considered with any specific Seneca statute and existing easement. Transportation maps establish routes and planning responsibilities; they do not adjudicate the validity of the underlying grant. [S15] [S31] [S63]
The Thruway dispute remains materially relevant. The Thruway Authority’s January 2026 disclosure describes a September 30, 2025 magistrate recommendation concerning the Cattaraugus easement and subsequent objections. The Nation describes that recommendation as a legal victory. A recommendation is not an entered final district-court judgment; the Phase 1 record does not verify final adoption, a settlement, or a damages award. Claimed invoices and requested compensation are not adjudicated amounts. A current docket and the actual easement are essential before relying on this corridor in a transaction. [S57] [S58]
7. Settlement Act and Buffalo Land Status
7.1 The Statutory Acquisition Mechanism
The SNSA is Public Law 101-503, 104 Stat. 1292, enacted November 3, 1990. Section 6 provides $35 million from the United States and $25 million from New York, totaling $60 million in the specified cash and development components. Former 25 U.S.C. §§ 1774–1774h have been editorially omitted from the Code as special rather than general provisions. Omission is not repeal; the session law remains the relevant text. [S17] [S18]
Section 8(c) permits land within the Nation’s aboriginal area in New York or near former reservation land to be acquired with qualifying appropriated funds. The statute provides a 30-day state/local comment period concerning removal from real-property tax rolls and then a 30-day period for the Secretary’s contrary determination. Absent such a determination, qualifying acquired land becomes subject to the federal restriction against alienation in § 177 and is held in restricted fee. It also separately addresses additions to boundaries of Allegany, Cattaraugus, or Oil Spring. Funding, geography, notice, and the federal record must be tested for each acquisition. [S17, § 8(c)]
Restricted fee means the Nation holds title subject to a federal restriction against alienation. Trust land ordinarily means the United States holds legal title in trust for the beneficiary. Ordinary fee ownership does not itself establish either status. City of Sherrill v. Oneida Indian Nation, 544 U.S. 197, rejects unilateral restoration of tax immunity merely by open-market reacquisition; Chaudhuri distinguishes the congressionally authorized SNSA process. [S19] [S60]
7.2 The Casino Tract
Chaudhuri records the Nation’s October 3, 2005 acquisition of the approximately nine-acre Buffalo tract and the statutory process that resulted in restricted fee. The court upheld the tract as a dependent Indian community under 18 U.S.C. § 1151(b), based on federal set-aside and superintendence. It also resolved the litigated IGRA issues, including the distinction between restricted fee and land acquired in trust for purposes of the after-acquired-land restriction. The court’s institutional case history records denial of certiorari. [S19, slip op. pp. 24–25, 44–53, 61–68] [S20]
This is strong legal evidence for the adjudicated tract. It is not a certified list of current SBLs. The casino’s public address, 1 Fulton Street, is a starting locator; it is not a legal description. Nine class-693 assessment records are marked as casino-area candidates in the workbook, with their individual crosswalk explicitly unresolved. A property-class code is not a federal determination. [S19] [S21]
7.3 Parcel Findings and Verification Levels
The 15 downtown/nearby Nation or gaming records are: 106 Michigan; 124 Chicago; 180 Perry; 225 Perry; 230 South Park; 33 Fulton; 37 Marvin; 41 Fulton; 42 Fulton; 49 Fulton; 5 Miami; 76 Fulton; 85 Michigan; 89 Michigan; and 97 Michigan. The workbook preserves each SBL, assessment owner, deed book/page, roll date, acreage where populated, classification, confidence statement, and missing record. Zero acreage entries are treated as unknown, not zero-area parcels. No aggregate acreage is asserted. [S21] [S22]
The 2026 roll identifies Seneca Gaming Corporation at 106 Michigan (P01; SBL 122.05-7-6.2), with a December 20, 2024 deed reference, Book 11440, Page 6046. A corporate announcement independently associates the site with the enterprise’s mural. The property is roll 1, a taxable-roll signal. Neither source proves restricted-fee status. The same uncertainty applies to roll-1 Nation records at 37 Marvin (P07; 122.23-4-10) and 76 Fulton (P12; 122.23-4-9), both carrying March 19, 2021 deed references. [S21] [S29] [S65]
180 Perry (P03; 111.17-9-1) is recorded to the Nation with a November 22, 2019 deed reference and roll 8 classification. Roll 8 indicates wholly exempt assessment treatment; it does not identify the legal basis of exemption or establish Indian-country status. Likewise, the 1993 dates on certain casino-area records cannot be reconciled to the 2005 acquisition narrative without deeds and subdivision history. These discrepancies are retained rather than silently corrected. [S21] [S65]
212 Ohio (P16; 122.05-10-5.1) remains in the inspected roll under Franklin Terminals Inc. A September 2025 news report described a purchase contract concerning part of that property. It is an acquisition lead, not a verified Nation closing. A later deed, subdivision, or federal designation was not obtained. 265 Skillen (P17; 77.34-2-10.11) is recorded to the Nation but lies outside the downtown scope and is retained only as an exclusion/reference entry. [S21] [S28]
7.4 5 Miami Street: Designation and Litigation
5 Miami (P11; SBL 122.10-1-1) is recorded to the Nation with a November 30, 2022 deed reference, Book 11411, Page 1675. The filed federal complaint states that DOI allowed restricted-fee status on February 14, 2023 after a December 2022 notice. It challenges the funding, statutory eligibility, notice process, and related federal action. These are the City’s allegations, not established defects. The complaint is City of Buffalo v. U.S. Department of the Interior et al., W.D.N.Y. No. 1:26-cv-02275, filed October 8, 2026. [S21] [S24, ¶¶ 22–32, 60–95]
124 Chicago (P02; 122.31-4-9) carries the same deed book/page as 5 Miami, suggesting a possible common conveyance. That is an inference only. Its “9999” assessment deed date is invalid and is recorded as unknown. The same deed reference cannot establish that it falls within the federal designation’s legal description. [S21]
The City separately announced state-court proceedings to stop the proposed development; the actual state pleading and orders were not obtained. The Nation’s account asserts sovereign authority and describes a gas station on the Miami/Ohio site. Conflicting project descriptions and legal positions are preserved as attributed accounts. Neither a City press release nor a Nation announcement substitutes for the federal administrative record, a legal description, or a court order. [S25] [S27]
No final federal merits decision or verified injunction was found in the sources reviewed. The correct diligence posture is to obtain the 2023 decision and exhibits, trace qualifying purchase funds, match the federal tract to the deed and current SBLs, and update both dockets. Until then, a development or financing analysis should not assume either that the designation is invalid or that its validity is conclusively settled.
8. Jurisdiction: Who Can Govern, Hear, and Enforce?
8.1 Four Questions Must Be Kept Separate
The applicable substantive law, the court’s adjudicatory jurisdiction, immunity from suit, and the ability to enforce a judgment are distinct. Ownership, Indian-country status, membership, the conduct’s location, the identity of the counterparty, and the particular statute can change the result. A waiver of immunity does not itself create jurisdiction, and state-court jurisdiction does not automatically supply local regulatory power. [S33] [S35] [S36] [S37]
18 U.S.C. § 1151 identifies reservation land, dependent Indian communities, and allotments as Indian country, including specified rights-of-way. Cattaraugus’s reservation basis and the Buffalo casino’s dependent-community basis must not be conflated. The definition supplies a starting category, not a complete answer to taxation, zoning, policing, or civil litigation. [S30] [S19]
8.2 Criminal and Enforcement Authority
25 U.S.C. § 232 grants New York jurisdiction over offenses by or against Indians on reservations within the state, with its hunting/fishing proviso. United States v. Cook, 922 F.2d 1026, treats that authority as concurrent, not a replacement for federal jurisdiction. Federal allocation also depends on the General Crimes Act, Major Crimes Act, independently applicable federal offenses, and their exceptions. The statute’s reservation wording should not be applied mechanically to every newly designated dependent community without analysis. [S32] [S34] [S62]
For non-Indian offenders against Indian victims, Oklahoma v. Castro-Huerta, 597 U.S. 629, recognizes concurrent state and federal jurisdiction, subject to applicable preemption. It is not a holding that states may prosecute every Indian defendant. Tribal prosecution of non-Indians is generally limited; 25 U.S.C. § 1304 provides defined covered-crime authority for participating tribes that satisfy statutory protections. Current Seneca implementation and operational capacity were not established. [S38] [S39]
New York Indian Law §§ 8 and 79, including the 2026 chapter amendment, address intrusions, tribal authorization, and Nation-requested law-enforcement agreements. Section 79 preserves existing legal authority rather than allowing an agreement to repeal governing law. Executed agreements and officer appointments remain to be obtained. H.R. 7065, the recent Senate proposal, and New York A11574 are tracked separately from enacted law; no effective repeal of § 232 was verified. [S40] [S41] [S42] [S43] [S44] [S45]
8.3 Civil Courts, Regulation, and Nonmembers
25 U.S.C. § 233 grants New York courts civil jurisdiction subject to substantial provisos. It preserves appropriate tribal customs, does not authorize reservation-land taxation, execution, or alienation, and excludes jurisdiction over specified pre-September 13, 1952 land events. Its limited provision concerning member-to-member possession disputes is not a general authorization to sell Nation land. [S33]
Cayuga Nation v. Campbell, 34 N.Y.3d 282, confirms that § 233 does not allow state courts to resolve internal tribal government disputes. Bryan v. Itasca County, 426 U.S. 373, concerns Public Law 280 rather than New York’s statute, but supplies the important distinction between civil adjudication and general taxing/regulatory authority. Neither should be used as a claim that state law never applies. [S35] [S36]
Montana v. United States, 450 U.S. 544, limits tribal civil authority over nonmembers on non-Indian fee land, subject to consensual-relationship and direct-threat exceptions. Application requires the specific land, activity, and nexus; tribal-owned land and exclusion powers require their own analysis. A contract with an enterprise, a trespass, an employment dispute, and internal Nation governance do not necessarily have the same forum or rule. The Jurisdiction register records these distinctions and the remaining factual predicates. [S37]
9. Taxation: Rules by Taxpayer, Transaction, and Land
9.1 Land and Improvements
Protected Nation reservation land benefits from treaty and federal protections and New York Real Property Tax Law § 454 and Indian Law § 6. Special assessments require attention to RPTL § 490. Section 233 does not authorize taxation or execution against protected reservation land. For Buffalo, the statutory land-status process and parcel-specific exemption basis must be established; an ordinary purchase alone does not eliminate taxation. [S05] [S08] [S33] [S47] [S48] [S60]
Improvements, leases, and separately held business interests require examination of ownership, the taxing statute, the lease and federal approvals, and preemption. This report makes no blanket finding that every improvement is exempt or taxable. It also does not assume New York imposes a general personal-property ad valorem tax. A tax-roll exemption is an administrative fact; it is not proof that every transaction conducted there is exempt. [S33] [S47] [S61]
9.2 Income and Entity Form
An individual Seneca member generally remains subject to federal income tax unless a specific exemption applies. Perkins squarely rejects the claimed treaty exemption for the individual gravel income at issue. New York’s IT-225 instructions, modification S-128, provide a qualifying subtraction for an enrolled individual who lives and works on a reservation and satisfies the stated income conditions. Federal and state income treatment therefore must be analyzed separately. [S46] [S54] [S55]
Federally recognized tribal governments generally are not subject to federal income tax. A final federal regulation applicable to periods beginning January 1, 2026 provides that qualifying wholly tribal-owned entities organized exclusively under the owning tribe or tribes’ laws are not recognized as separate entities for federal income-tax purposes. Specified employment and excise treatment remains separate. A member-owned business, state-chartered corporation, or joint venture cannot simply assume the same result; charter, ownership, and the relevant tax must be checked. [S55] [S56]
SNSA § 8(a) protects the specified settlement payments, funds, and income from state/local taxation and listed processes. It is a fund-specific statutory protection, not a general exemption for unrelated commercial income. [S17]
9.3 Sales, Cigarettes, and Fuel
DTF-801 provides a conditional New York exemption for qualifying purchasers and qualifying delivery, subject to the form’s residence, payment, entity, use, and vehicle rules. The form is for qualifying personal-use purchases, not resale, and excludes cigarettes. Its qualified-reservation definition can include qualifying restricted-fee land over which the Nation exercises governmental power. A purchaser or seller must establish the facts rather than rely on the word “reservation” in a business address. [S49]
Nonmember retail purchases are not categorically exempt. Department of Taxation & Finance v. Milhelm Attea & Bros., 512 U.S. 61, permits reasonably tailored collection rules for taxes lawfully imposed on nonmember cigarette purchases. Taxpayer liability and a seller’s collection duty are different questions. Bracker requires a particularized federal, tribal, and state interest analysis in the preemption context it addresses; economic impact on a tribe alone is not a universal exemption. [S50] [S61]
Current New York cigarette guidance, updated September 3, 2026, requires stamping and precollection subject to the stated qualified-demand coupon/prior-approval processes and specific agreements. The guidance’s Oneida exception must not be transferred to Seneca sales. This research identifies the legal and administrative framework, not actual compliance by any particular retailer. [S51]
Fuel requires an additional distinction. Tax Law § 284-e distinguishes qualifying own-member consumption on the member’s qualified reservation from nonmember sales. Notice N-15-7 separately allows specified fuel taxes not to be passed through on direct purchases by the Nation when the stated delivery, title, and payment conditions are met; reporting and transporter requirements remain. That upstream purchase treatment does not itself decide downstream retail tax liability for nonmembers. Actual supply chain, incidence, documentation, agreements, and current litigation must be examined before forecasting a fuel business’s taxes. [S52] [S53]
10. Unresolved Records and Recommended Phase 2
The decisive unresolved items are: recorded deed images and subdivision history; the original 2005 and 2023 federal land-status decisions and tract exhibits; the 5 Miami administrative record and current federal/state dockets; a certified Cattaraugus boundary and site survey; current Nation codes and site approvals; and entity-specific tax and enforcement arrangements. The Open Issues register assigns priority, identifies evidence already obtained, and states how each gap limits a conclusion.
Recommended Phase 2 begins with a specific proposed site and transaction. First obtain the deed/legal-description chain and federal-status record, then reconcile the survey and SBLs. Next confirm the interest available for transfer or collateral, Nation and federal approvals, access and utility rights, and the chosen entity’s authority. Only then analyze zoning/building/environmental requirements, tax incidence and collection, immunity waiver and forum terms, enforceability, insurance, financing, and economic-development eligibility.
For the Miami/Ohio project, prioritize the 2023 DOI decision, qualifying-funds tracing, deed 11411/1675 and its complete schedule, and both litigation dockets. For Cattaraugus, prioritize Nation land records, the exact member/leasehold interest, consent requirements, and any right-of-way implicated by the site. Formal legal citator and title review belong in the transaction workstream. These recommendations have not been executed or committed to paid services.
11. Maps, Registers, and Source Appendix
The companion register workbook and four-page map exhibit are linked below. Exhibit 1 is the Nation’s 2020 Cattaraugus planning map reproduced in its 2024 plan. Exhibit 2 is the corresponding Buffalo map dated October 16, 2020, which predates the Miami designation and later acquisitions. Exhibit 3 uses official county tax polygons to locate the selected downtown records without drawing a sovereign boundary. Exhibit 4 is the 1844 historical Buffalo Creek map. Map colors and parcel ownership classifications do not adjudicate federal status. [S15] [S21] [S22] [S59]
