Indian Gaming Regulatory Act (IGRA)

The Indian Gaming Regulatory Act (1988) — codified at 25 U.S.C. §§ 2701–2721 — created the federal framework for tribal casino gambling, authorizing gaming on Indian lands as an exercise of tribal sovereignty and establishing a three-tier regulatory structure that now governs a $40+ billion/year industry operating across more than 500 tribal gaming facilities in 29 states. IGRA divides gaming into three classes: Class I (traditional ceremonial games, unregulated), Class II (bingo and non-banked card games, regulated by the tribal-federal National Indian Gaming Commission), and Class III (casino-style gaming — slots, blackjack, roulette — which requires a tribal-state compact negotiated with the state governor and approved by the Secretary of the Interior). States must negotiate Class III compacts in good faith, and tribes may sue in federal court if states refuse — though the Supreme Court's Seminole Tribe v. Florida (1996) limited this remedy. Tribal gaming revenues fund government services, healthcare, education, and housing for tribal members, with some tribes distributing per-capita payments directly to enrolled members. The NIGC oversees tribal gaming ordinances and can impose civil fines (per-violation cap adjusted for inflation; ~$65,655 per 2026 CMP schedule).

Current Law (2026)

Legal Authority

• 25 U.S.C. § 2701-2702 — Congressional findings and declaration of policy (tribal gaming is a means of promoting tribal economic development, self-sufficiency, and strong tribal governments; Congress recognizes the need to establish federal standards for gaming on Indian lands)
• 25 U.S.C. § 2703 — Definitions (defines the three classes of gaming, "Indian lands," "net revenues," and other key terms; "Indian lands" means any lands within the limits of any Indian reservation or lands held in trust by the United States for an Indian tribe)
• 25 U.S.C. § 2710 — Tribal gaming ordinances (Class II gaming requires a tribal ordinance approved by the NIGC chairman; Class III gaming requires both an approved ordinance AND a tribal-state compact; tribes must use net gaming revenue for tribal government, economic development, general welfare, local government funding, or per capita payments)
• 25 U.S.C. § 2711 — Management contracts (contracts with non-tribal managers must be approved by NIGC; management fees capped at 30% of net revenue (40% in limited circumstances); contract term limited to 5 years (7 years in limited circumstances))
• 25 U.S.C. § 2713-2714 — Civil penalties and judicial review (NIGC may assess civil fines up to the inflation-adjusted per-violation cap (~$65,655 per 2026 schedule); may order temporary or permanent closure of gaming operations; tribal operators may seek judicial review in federal court)

How It Works

IGRA created the legal framework for what has become a $41 billion industry — tribal gaming. It balances tribal sovereignty and economic self-determination against state regulatory interests, creating a unique cooperative federalism structure that has transformed the economic landscape for hundreds of tribes.

IGRA under 25 U.S.C. § 2703 divides gaming into three classes with different regulatory frameworks: Class I (traditional Indian gaming and social games for minimal prizes, regulated exclusively by tribes), Class II (bingo, pull-tabs, lotto, and non-banked card games, regulated by tribes under National Indian Gaming Commission oversight), and Class III (the full range of casino-style gaming — slots, blackjack, roulette, craps, sports betting — which requires both a tribal ordinance approved by NIGC and a tribal-state compact under 25 U.S.C. § 2710(d)). The Class II/III distinction is legally and economically crucial: Class II requires no state involvement, while Class III requires state cooperation. States must negotiate Class III compacts in good faith under 25 U.S.C. § 2710(d)(3), but the Supreme Court's Seminole Tribe v. Florida (1996) ruling — holding that the Eleventh Amendment bars tribes from suing states that refuse to negotiate — effectively gives states a veto; in practice, tribes often agree to significant revenue-sharing payments to states in exchange for gaming rights, since federal remedies for bad-faith refusals have rarely succeeded.

The industry IGRA created generates approximately $41 billion in annual revenue — more than Las Vegas and Atlantic City combined — funding tribal government services, healthcare, education, infrastructure, housing, and cultural preservation programs through the BIA self-governance framework, while employing approximately 700,000 people including many non-tribal members. IGRA under 25 U.S.C. § 2710(b)(2)(B) requires net gaming revenue to be used for five purposes: tribal government operations, general tribal welfare, tribal economic development, charitable donations, and local government operations; per capita payments to members require Secretarial approval and a revenue allocation plan ensuring adequate government funding. The National Indian Gaming Commission (NIGC) — a three-member commission within the Department of the Interior — reviews and approves tribal gaming ordinances, conducts background investigations on management contractors, monitors operations, enforces IGRA requirements, and can assess fines or order closure for violations.

State Variations

Implementing Regulations

• 25 CFR Part 290 — Tribal Revenue Allocation Plans: the BIA rules governing how tribes must structure and get federal approval for distributing net gaming revenues, particularly when they make per capita payments directly to tribal members. Key provisions:

  • § 290.1 — Purpose: Part 290 establishes the procedures for submitting, reviewing, and approving tribal revenue allocation plans (RAPs) — IGRA requires any tribe that wants to distribute gaming revenues as per capita payments to tribal members to have an approved RAP; without approval, per capita distribution violates IGRA regardless of the gaming class
  • §§ 290.10–290.11 — Violation for unapproved per capita: a tribe is in violation of IGRA if it makes per capita payments from either Class II or Class III net gaming revenues without an approved RAP; the violation applies regardless of whether a RAP has been submitted but not yet approved — approval must precede distribution
  • § 290.12 — Plan contents — percentage breakdown: the RAP must include a percentage breakdown of all net gaming revenue uses — the IGRA requires allocation to (a) tribal government operations, (b) economic development, (c) welfare of the tribe and members, (d) donations to charitable organizations, and (e) local government operations and services; per capita payments come out of the allocation to tribal member welfare; the plan must show that adequate funding for tribal government services is maintained before per capita payments are authorized
  • § 290.13–290.14 — Conditions for per capita: per capita payments can only be made after the Appropriate Bureau Official (ABO) approves the RAP; the tribe sets its own eligibility criteria (which members receive payments and how much); distributions to minors and legal incompetents require special handling but do NOT go into BIA- or OTFM-held accounts — the tribe manages these
  • § 290.19 — 60-day ABO review timeline: the ABO must review and act on a submitted RAP within 60 days; if the ABO fails to act within 60 days, the RAP does not automatically become approved — the tribe must continue to await action; the BIA's review addresses whether the plan adequately funds tribal government services before distributing per capita

  Part 290 is the financial accountability mechanism for the most politically visible aspect of tribal gaming: the per capita check. Tribal members in gaming tribes receive per capita distributions ranging from a few hundred dollars to tens of thousands annually depending on the tribe's gaming revenues and membership size. The RAP approval requirement ensures the federal government has reviewed that the tribe is funding essential government services before distributing to members — a condition designed to prevent gaming revenues from being fully distributed to members while tribal government programs go unfunded. The largest per capita distributions (e.g., some California gaming tribes) can exceed $20,000–$30,000 per member per year.

• 25 CFR Part 291 — Class III gaming procedures (Secretary-issued procedures, eligibility, filing, comment periods, monitoring, amendments, duration)

• 25 CFR Part 292 — Gaming on Trust Lands Acquired After October 17, 1988: the "two-part determination" and exception regulations implementing IGRA § 20, which generally prohibits gaming on trust lands acquired after IGRA's 1988 enactment but provides specific exceptions. Key provisions:

  • § 292.1 — Purpose — the general prohibition and exceptions: IGRA § 20 (25 U.S.C. § 2719) prohibits gaming on lands acquired in trust after October 17, 1988 — the "Indian lands" gaming eligibility rule — but creates five exceptions: (1) initial reservation lands acquired as part of a tribe's first reservation; (2) restored lands for tribes restored to federal recognition; (3) settlement of land claims; (4) two-part determination (Secretarial discretion based on benefits to the tribe + concurrence of the governor); (5) off-reservation gaming under tribal-state compacts for specific purposes
  • §§ 292.10–292.12 — Restored tribe exception: a tribe that was terminated and subsequently restored to federal recognition may game on "restored lands" — lands that have a significant nexus to the tribe's tribal community as it existed at the time of termination; qualifying as "restored to federal recognition" requires evidence of formal federal restoration (Congressional enactment, administrative action, or federal court order); the lands must have geographic and historical connections to the tribe's traditional territory
  • § 292.13–292.19 — Two-part Secretarial Determination: for lands that don't qualify for a specific exception, a tribe may seek a Secretarial Determination — a discretionary decision by the Secretary of the Interior that gaming on the land is "not detrimental to the surrounding community" AND in the "best interest of the tribe"; this is the most controversial IGRA gaming mechanism, used by tribes seeking off-reservation casinos in major metropolitan areas; the process requires:
    • A formal application to the BIA Regional Director describing the proposed gaming facility, its projected economic impacts on the tribe, and its potential detrimental impacts on the surrounding community (§ 292.16–292.18)
    • A Regional Director consultation process soliciting comments from state and local governments, federal agencies, and the public within a 60-day comment window (§ 292.19)
    • The Secretary's two-part determination — (1) the gaming is in the best interest of the tribe AND (2) it is not detrimental to the surrounding community
    • Governor's concurrence (§ 292.26): after the Secretary makes the determination, the Governor of the state must concur in writing before gaming can proceed; this concurrence requirement gives state governments an effective veto over off-reservation gaming in their state — it has been used by multiple governors to block Secretarial Determinations
  • § 292.27 — Effect of no Secretarial Determination or no Governor's concurrence: if the Secretary does not make the determination or the Governor does not concur, gaming is prohibited on the newly acquired lands; the tribe may reapply after material changes in circumstances

  The two-part Secretarial Determination process has been the most litigated mechanism in federal Indian gaming law. High-profile off-reservation casino proposals — Carcieri v. Salazar (2009, Supreme Court restricting who qualifies as "Indian" for trust land acquisition), Wilton Rancheria in California, and numerous New England casino proposals — have turned on the "restored lands" exception, the validity of trust land acquisition, and the governor's concurrence requirement. The geographic reach of IGRA's prohibition on post-1988 trust land gaming is the primary regulatory constraint on tribal casino expansion in new markets.

• 25 CFR Part 542 — Minimum Internal Control Standards (MICS) (29 sections — the NIGC's comprehensive baseline operational standards for tribal gaming facilities; every Class II and Class III gaming operation must adopt internal controls at least as stringent as Part 542, with the option to adopt more stringent tribal internal controls approved by the NIGC):

  • § 542.1 — Purpose and transition: Part 542 previously set direct federal MICS requirements for tribal gaming; following amendment, Part 542 now primarily establishes the federal floor that tribal gaming operations must meet or exceed in their own tribal internal control standards (TICS) — tribes may replace or supplement Part 542 standards with NIGC-approved TICS that provide equivalent or greater protection
  • § 542.10 — Keno standards: gaming operations conducting keno must maintain computer applications for the game that generate unalterable records; draw records must identify individual ticket numbers; pay records must be reconciled to draw records; all keno computers must have independent software validation
  • § 542.12 — Table games standards: for blackjack, roulette, craps, and other table games — card counting and shuffle procedures must be documented; each game must have a Table Inventory Form completed at each shift change; table drop must be counted in a secure area with at least two employees; all currency transactions are reconciled to table results; supervisors must verify and sign drop records
  • § 542.13 — Gaming machine (slot) standards: gaming machines must undergo annual inspections by qualified technicians; machine meters must be read and reconciled on a schedule; each machine's theoretical and actual payout rates must be tracked; machine access logs must identify all personnel who opened the machine and why; currency collected from machines must be counted by two employees and reconciled to machine meter counts
  • § 542.14 — Cage standards: the gaming cage (cashier's operations center) must have dual-control procedures for all cash transactions; imprest (fixed balance) accounts must be reconciled daily; all currency transactions over a specified threshold must be documented; the cage must maintain a "straps" log tracking cash bundles; bank deposits must be verified by two cage employees; the MICS are the tribal gaming equivalent of bank teller controls
  • § 542.15 — Credit standards: issuance of credit (markers) to players requires documented procedures including credit limits, issuance approval, and collection timelines; all outstanding markers must be reconciled; credit write-offs require specific approval levels; BSA/SAR obligations for credit transactions must be incorporated into credit standards
  • § 542.17 — Complimentary services and items: the "comps" system must be documented; written policies must govern who can authorize comps, what level of comps each management position can authorize without additional approval, and how comps are recorded; comps audits must verify that approval levels were followed; this provision prevents the comps system from being used to launder funds or provide undocumented benefits
  • § 542.18 — Variance process: a gaming operation may apply for a variance from any MICS standard if the tribe can demonstrate that the variance provides equal or greater protection against illegal activity; variances must be approved by the NIGC; approved variances are published; this flexibility allows tribes to use technology or procedures that achieve the same control objective without strictly following the regulation's prescribed method
  • § 542.19 — Accounting standards: gaming operations must maintain books and records that allow preparation of a complete balance sheet, income statement, and statement of changes in financial position; daily cash counts must balance; monthly financial statements must reconcile to daily operational records; annual gaming revenue audit is required by an independent CPA; financial reporting must comply with gaming industry accounting standards

  Part 542 is the operating manual for tribal gaming internal controls — it reflects decades of experience managing the specific fraud risks of gaming operations (false jackpot claims, collusion between players and dealers, unauthorized machine access). The NIGC conducts compliance reviews of tribal gaming operations and can assess penalties up to the inflation-adjusted per-violation cap (~$65,655 in 2026) for MICS deficiencies. Tribal gaming commissioners trained in MICS administration are the day-to-day enforcement mechanism — they are tribal officials who must pass NIGC background checks and maintain operational independence from tribal management. Recent rulemakings: 70 FR 47107 (August 2005) — major MICS revision; 67 FR 43400 (June 2002) — original MICS comprehensive promulgation.

• 25 CFR Part 518 — Self-Regulation of Class II Gaming: IGRA § 2710(c) allows a tribe to obtain a certificate of self-regulation for Class II gaming if its gaming operation meets specific performance criteria — freeing it from certain ongoing NIGC oversight in exchange for demonstrating institutional competence. Self-regulation is the highest level of autonomy available under IGRA's Class II framework:

  • § 518.1 — Eligibility: to obtain a self-regulation certificate, a tribe must have operated a Class II gaming facility for at least three years; must have completed five years of continuous audited financial statements; and must demonstrate that the tribal gaming operation's internal controls, accounting, and audit functions are adequate; the tribe submits a petition demonstrating eligibility to the NIGC Commission
  • § 518.2–518.6 — Application process: the petition must include three years of audited financial statements, copies of current tribal gaming ordinances and internal control standards, background investigation results for key employees and primary management officials, and a description of the tribe's monitoring and investigation capability; NIGC staff reviews the petition and makes a recommendation to the full Commission; the Commission votes to issue or deny the certificate
  • § 518.10 — Ongoing obligations: a self-regulating tribe must continue to submit annual audited financial statements, annual reports on its gaming operations, and notifications of any changes to its gaming ordinance or internal controls; self-regulation does not mean no oversight — it means reduced federal oversight with stronger tribal oversight substituting for NIGC compliance reviews
  • § 518.12 — Scope of relief: while a tribe holds a self-regulation certificate, the NIGC's normal investigative powers over Class II gaming operations are suspended — the Commission retains authority to investigate if it has reason to believe a violation has occurred, but routine compliance reviews and inspections are waived; this reduces the compliance burden and gives tribes a degree of regulatory independence that reflects their government-to-government status
  • § 518.13 — Revocation: NIGC may revoke a self-regulation certificate if the tribe fails to submit required reports, violates IGRA or NIGC regulations, or if the Commission determines that continued self-regulation would undermine the integrity of Class II gaming; before revocation, the Commission must provide notice and opportunity for a hearing; revocation returns the tribe to standard NIGC oversight

  Self-regulation certificates are relatively rare — fewer than 20 tribes hold them at any given time. The three-year minimum operating history and five-year audit requirement mean only established gaming operations qualify. The certificate is a formal recognition of tribal governmental competence in gaming regulation, consistent with IGRA's underlying sovereignty framework.

• 25 CFR Part 556 — Background Investigations for Primary Management Officials and Key Employees: the NIGC's framework for pre-licensing background checks on the individuals who run tribal gaming operations, implementing IGRA's requirement (25 U.S.C. § 2706) that gaming facilities adopt licensing requirements at least as protective as Part 556. This Part applies to all Class II gaming and to Class III gaming unless the tribal-state compact assigns this responsibility elsewhere. Key provisions:

  • § 556.3 — Application requirements: every applicant for a primary management official or key employee position must submit a completed application that includes, at minimum: full legal name and any aliases; date and place of birth; Social Security number; home and work addresses for the preceding 5 years; employment history for the preceding 5 years (including any military service); all felony charges and convictions (regardless of jurisdiction); all gaming license applications, approvals, and revocations in any jurisdiction; a Privacy Act notice and a false statements notice (making false statements on the application a federal criminal offense under 18 U.S.C. § 1001)
  • § 556.4 — Investigative scope: the tribe must conduct a background investigation covering: prior criminal history (FBI records check, state criminal records); prior gaming regulatory records; employment history verification; financial history adequate to assess risk of financial exploitation; and character references; the investigation must use sources independent of the applicant and must be documented in a written report
  • § 556.5 — Eligibility determination: before issuing a gaming license, the tribe makes an eligibility determination based on the background investigation report; NIGC regulations identify factors that must be considered: felony convictions, crimes of dishonesty (fraud, theft, embezzlement), prior gaming license revocations, and conduct that would undermine the integrity of tribal gaming; the tribe's own gaming ordinance may establish additional disqualifying criteria; the eligibility determination is tribal — the NIGC does not approve individual licenses but reviews the tribe's ordinance and processes
  • § 556.6 — Forwarding to NIGC: before licensing a primary management official or key employee, the tribe must forward its eligibility determination and the investigative report to the NIGC for a 30-day review period; NIGC reviews the submission and may object to licensing the individual if the Commission determines the person poses a threat to the public interest or to effective tribal gaming regulation; if NIGC does not object within 30 days, the tribe may license the individual
  • § 556.7 — License duration and renewal: gaming licenses for primary management officials and key employees are valid for up to 2 years; renewal requires a new background investigation covering the intervening period; if a licensee is convicted of a gaming or financial crime after licensing, the tribe must revoke the license within 30 days of learning of the conviction

  Part 556 is the security screening backbone of IGRA's integrity framework. "Primary management officials" and "key employees" are defined broadly — they include the general manager, assistant manager, financial controller, security director, shift managers, and anyone else with supervisory authority over gaming or gaming revenue. The pre-licensing FBI records check requirement means every tribal gaming manager in the country has been fingerprinted through a federal channel, a level of employee screening that most private-sector employers do not approach. The NIGC maintains records of all licensing determinations; if a key employee is denied a license by one tribe and applies at another, the prior denial must be disclosed.

• 25 CFR Part 558 — Gaming Licenses for Key Employees and Primary Management Officials: the procedural counterpart to Part 556's investigative requirements, governing the actual licensing decision and the NIGC's role after a tribe completes its background investigation. Part 558 addresses what happens after the notice of results is filed with the NIGC:

  • § 558.2 — NIGC review of notice of results: upon receiving a complete notice of results and eligibility determination from the tribe (as required by § 556.6(b)(2)), the NIGC Chairman may, within 30 days, notify the tribe of any concerns or information suggesting the applicant poses a threat to the public interest or to effective gaming regulation; if the Chairman does not respond within 30 days, the tribe may proceed to license the individual
  • § 558.3 — Notification of license decisions: after licensing a primary management official or key employee, the tribe must notify the NIGC of the licensing decision; license records must be retained for the duration of employment plus a defined period thereafter; the NIGC uses these notifications to build and maintain its registry of licensed gaming personnel
  • § 558.4 — Post-licensing disqualifying information: if, after a license is issued, the NIGC receives reliable information indicating that a licensee may pose a threat to public interest or effective gaming regulation (including new criminal convictions, regulatory violations, or other disqualifying facts), the Chairman must immediately notify the tribe; upon notification, the tribe must suspend the license, provide the licensee written notice of the potential disqualification, and give the licensee a reasonable opportunity for a hearing before the tribe's gaming commission; the tribe must resolve the situation — revoke or reinstate — within 45 days

  Part 558 creates a continuous oversight loop: the NIGC's role doesn't end when a license is issued. Ongoing monitoring means that a manager convicted of fraud two years into their tenure triggers a tribal licensing review and NIGC notification. The 30-day NIGC review window after each initial notice of results is the federal government's last check on the tribal licensing decision before it becomes effective — a check that is triggered automatically by the Part 556 notification requirement.

• 25 CFR Part 533 — Approval of Management Contracts: the NIGC rules implementing IGRA § 2711, which prohibits tribal gaming management contracts from taking effect without the NIGC Chairman's approval. The management contract approval framework protects tribes from exploitative arrangements with outside operators — a protection motivated by pre-IGRA history in which non-Indian promoters structured gaming agreements that captured most gaming revenues at tribal expense:

  • § 533.1 — Requirement for approval: any Indian tribe entering a management contract for the operation of a Class II or Class III gaming activity must obtain the Chairman's prior approval; a tribe must submit the contract within 60 days of its execution; unapproved management contracts are void under federal law — the tribe and the management contractor cannot operate under them
  • § 533.3 — Required contract provisions: to be approvable, the management contract must include: the percentage of net revenues paid to the management contractor (subject to the § 531.1 cap of 30% of net revenues, or up to 40% in exceptional cases where a higher fee is warranted by demonstrated extraordinary start-up costs); a specified management fee payment schedule; a 7-year maximum term (with very limited exceptions); provisions giving the tribe authority to annually approve the operating budget, establish personnel policies, and terminate the management contractor for cause; a requirement that the tribe retain the ability to hire and fire the facility's key employees; and a provision that the tribe's right to exercise sovereign immunity is not waived
  • § 533.4 — Chairman's decision timeline: the Chairman must approve or disapprove a management contract within 180 days of receipt; if the Chairman fails to act within 180 days, the tribe may seek relief from a federal district court; the Chairman may extend the 180-day period with the tribe's agreement; disapproval must be based on specific standards set in § 533.6

  The management contract approval requirement has blocked numerous arrangements in which outside entities — including some with organized crime connections in IGRA's early years — sought disproportionate shares of tribal gaming revenues. The 30%/40% fee cap is IGRA's most direct constraint on what management companies can earn; tribal gaming revenues generate billions annually, so a management fee cap of 30% can still represent enormous sums in large operations. The 7-year term limit prevents perpetual lock-in arrangements, and the tribal-control provisions ensure that the tribe remains the actual operator of the gaming facility even when it contracts out day-to-day management functions.

• 25 CFR Part 575 — Civil Fines: the NIGC's enforcement penalty regulation, setting the framework for civil fines assessed against tribes, management contractors, and individuals for IGRA violations. Civil fines are one of the NIGC's core enforcement tools alongside temporary closures and management contract terminations:

  • § 575.4 — Fine amount: the Chairman may assess a civil fine of up to $65,655 per violation against a tribe, management contractor, or individual operating Indian gaming for each notice of violation issued; the per-violation cap is periodically adjusted for inflation (the original IGRA figure was $25,000); in assessing the fine amount, the Chairman must consider: the nature, circumstances, extent, and gravity of the violation; any prior history of violations; any good faith efforts to correct the violation; the effect of the fine on the violator's ability to continue gaming operations; and whether the violation involved a willful or knowing disregard of IGRA or NIGC regulations
  • § 575.5 — Procedures: within 15 days of service of a notice of violation, the respondent may submit written information to the Chairman addressing the alleged violation, its circumstances, or mitigating factors; after reviewing any such submission, the Chairman issues a proposed civil fine assessment; the respondent then has the right to request a hearing before an administrative law judge under Parts 584 or 585 of this chapter
  • § 575.6 — Reduction or waiver: upon written request submitted before any appeal hearing is filed, the Chairman may reduce or waive a civil fine if the respondent demonstrates: the violation was minor or technical; the violation was corrected immediately upon discovery; or the fine would impose an undue hardship on the gaming operation that would harm the tribe's ability to fund governmental services; the settlement authority allows the NIGC to resolve most enforcement matters without formal adjudication
  • § 575.7 — Final assessment: if the respondent does not timely request a hearing, the proposed civil fine becomes a final order of the Commission; Commission orders are enforceable in federal district court, and unpaid fines can be referred to the Department of Justice for collection

  Civil fine authority gives the NIGC teeth without requiring closure of a gaming facility — the sanction most disruptive to tribal government revenues. For most violations (MICS deficiencies, licensing process errors, management contract non-compliance), the NIGC can impose financial penalties that create corrective pressure while gaming operations continue. The $65,655 per-violation ceiling, while significant, is often a fraction of daily gaming revenues at large operations, meaning the Commission's ability to assess fines for each discrete violation (rather than one global fine per inspection) is the more powerful enforcement feature.

• 25 CFR Part 573 — Compliance and Enforcement: the NIGC's enforcement ladder framework — the procedural escalation from voluntary compliance through formal sanctions. The Part establishes how the Commission moves from identifying a potential problem to ordering a gaming facility closed:

  • § 573.1 — Voluntary compliance as primary goal: the NIGC's stated enforcement philosophy begins with voluntary compliance — NIGC staff and the tribe attempt to resolve any compliance issue informally before the Chairman takes formal action; this reflects IGRA's government-to-government framework, in which tribal gaming authorities are preferred partners rather than subjects of enforcement; formal enforcement actions are reserved for situations where informal resolution fails
  • § 573.2 — Letter of concern: before any formal enforcement action, NIGC staff may issue a letter of concern to the tribe or gaming operation describing the compliance concern, the facts underlying it, a preliminary assessment of the applicable law, and a timeframe for the tribe to respond with additional information or a corrective plan; a letter of concern is not a violation finding — it is a pre-enforcement notice designed to give tribes the opportunity to self-correct; the letter is the first step in the escalation ladder and the point at which most enforcement matters are resolved
  • § 573.3 — Notice of violation: if voluntary compliance efforts fail, the NIGC Chairman may issue a formal notice of violation to any person — the tribe, a management contractor, or an individual — for violations of IGRA, NIGC regulations, or any tribal ordinance or resolution the Chairman has approved; the notice must identify the specific federal or tribal provision violated, describe the specific conduct that constitutes the violation, the date of the violation, and the corrective action required; the notice starts the formal enforcement clock and triggers the respondent's right to contest and be heard
  • § 573.4 — Order of temporary closure: the most immediate sanction — the Chairman may issue an order closing all or part of a gaming operation simultaneously with or after a notice of violation when substantial violations are present, specifically: (1) the respondent fails to correct a violation after notice; (2) gaming is conducted in a manner presenting an immediate threat to public health or safety; (3) gaming is being conducted without tribal authorization or on lands not eligible for gaming; or (4) the tribe has failed to pay assessed civil fines; a temporary closure order can halt gaming operations immediately, making it the most impactful NIGC enforcement tool; tribes may contest closure orders under appeal procedures in NIGC subchapter H
  • § 573.5 — Final agency action: an enforcement action (notice of violation, temporary closure order, civil fine) becomes final Commission order when: the respondent fails to timely appeal; or the respondent enters into a settlement agreement resolving the matter; final orders are enforceable in federal court; settlements frequently involve corrective action plans and monetary payments in lieu of continued formal proceedings

  Part 573 creates an enforcement gradient calibrated to IGRA's dual objectives of tribal self-determination and gaming integrity. The letter of concern and notice of violation pathway gives tribes advance warning and an opportunity to correct before facing financial or operational sanctions. The temporary closure authority is the Commission's most powerful tool — it can be used without prior notice when public safety is at risk or when gaming is occurring without legal authorization. In practice, the vast majority of NIGC enforcement matters are resolved through the letter of concern or notice of violation stage; temporary closures are rare and typically reserved for situations involving criminal activity, tribal governmental dysfunction, or persistent non-compliance with license or MICS requirements. No major rulemakings since the 2013 revision (78 FR 41476) that clarified the voluntary compliance framework and letter-of-concern procedures.

• 25 CFR Part 293 — Class III Gaming Compact Review (BIA — the regulatory framework governing the Secretary of the Interior's review of tribal-state gaming compacts submitted for approval under IGRA § 11(d)(8), 25 U.S.C. § 2710(d)(8)). Class III compacts (covering casino-style games: slot machines, blackjack, baccarat, roulette, craps) must be negotiated between the tribe and the state and approved by the Secretary before taking effect — Part 293 governs that approval process:

  • § 293.10 — Secretarial review period: upon submission of a compact or compact amendment, the Secretary has 45 days to review and either approve or disapprove it; the 45-day clock begins when the BIA Regional Director receives a complete submission; the Secretary may disapprove only on specified statutory grounds — a compact cannot be disapproved because the Secretary disagrees with the policy choices negotiated by the tribe and state
  • § 293.12 — Deemed-approved mechanism: if the Secretary neither approves nor disapproves a compact within 45 days of submission, the compact is approved by operation of law — no affirmative action is required, and the tribe and state may proceed as if the Secretary had approved; the "deemed-approved" provision is a structural safeguard against indefinite federal delay preventing tribes from commencing authorized gaming; compacts that take effect by operation of law must still be published in the Federal Register to become effective
  • § 293.14 — Federal Register publication: all approved compacts (and compacts approved by operation of law) must be published in the Federal Register; publication is the trigger for the compact's legal effectiveness as a federal matter; BIA maintains a public repository of all effective compacts
  • § 293.15 — Grounds for disapproval: the Secretary may disapprove a compact only if it violates (a) IGRA itself; (b) any other federal law; or (c) the trust obligations of the United States to Indian tribes; the Secretary may not disapprove because the compact contains terms the Secretary disfavors, because the Secretary believes the tribe got a bad deal, or because the compact omits provisions the Secretary would prefer — disapproval is limited to legal invalidity, not policy disagreement
  • § 293.16 — Permitted compact provisions: under § 2710(d)(3)(C) of IGRA, compacts may address standards for the operation and maintenance of gaming facilities, licensing of gaming employees, environmental protection, public safety, and revenue sharing with the state for the costs of regulation; Part 293 reflects IGRA's list — states commonly negotiate for revenue-sharing payments (often 10–25% of net slot revenues) as a condition of compacting, and courts have split on whether such payments constitute impermissible taxation or permissible compensation for regulatory costs

  The Part 293 deemed-approval mechanism has been central to several high-profile Indian gaming disputes. When the Biden administration approved a compact between the Seminole Tribe of Florida and the State of Florida in 2021 (authorizing statewide mobile sports betting), a federal district court vacated the approval as exceeding IGRA's "Indian lands" requirement; the D.C. Circuit reversed in 2023, reinstating the compact. The Department of the Interior approved the Seminole compact within the 45-day window rather than allowing it to take effect by operation of law. States that fail to negotiate in good faith with a tribe (the § 2710(d)(3) obligation) may be sued in federal court, and if the court finds bad faith, a federal mediator can impose a compact — a structural backstop that gives tribes leverage in negotiations even when states are reluctant to share gaming revenues.

• 25 CFR Part 543 — Minimum Internal Control Standards for Class II Gaming. The NIGC's Class II-specific operational control standards, implementing IGRA § 2706(b)(10)'s requirement that NIGC promulgate regulations establishing minimum internal control standards for tribal gaming. Part 543 is the operational complement to Part 547's technical standards — together they form the Class II gaming compliance framework. Key provisions:

  • § 543.1 — Scope: Part 543 establishes minimum internal controls for all Class II games (bingo, pull-tabs, instant bingo, non-banked card games) on Indian lands; tribes must adopt a System of Internal Controls (SICS) at least as stringent as Part 543, or obtain NIGC approval of tribal internal controls that meet or exceed Part 543 standards
  • § 543.10 — Card game standards: supervision must be provided during card room operations by an agent with at least equal authority to those being supervised; all cards and shuffling equipment must be inspected before use; dealer rotation and relief procedures must be documented; end-of-shift counts and reconciliation must occur before the next shift takes the game
  • § 543.12 — Gaming promotions and player tracking: all gaming promotions (promotional credits, drawings, giveaways) must have documented rules establishing eligibility, award criteria, and promotional period; player tracking systems that accumulate credits must have access controls preventing unauthorized credit adjustments; all credits issued must be reconciled to promotional budget authorizations
  • § 543.14 — Patron deposit accounts and cashless systems: patron accounts (stored-value cards, ticket-in/ticket-out systems) must have dual-control procedures for account setup, deposits, and withdrawals; electronic fund transfer records must be retained; disputed account balances must have documented resolution procedures
  • § 543.15 — Lines of credit: gaming credit (markers) requires documented approval procedures with credit limit authorization levels; outstanding marker collection must follow documented timelines; marker write-offs require supervisory-level approval; BSA suspicious activity reporting obligations apply to credit transactions
  • § 543.17 — Drop and count: the "drop" (cash removed from gaming machines and card tables) must be collected by a secured team with at least two employees; the count room must be secured with access restricted to authorized count employees; count results must be independently verified and reconciled to gaming system records
  • § 543.18 — Cage, vault, and kiosk standards: the gaming cage must use imprest accounting (fixed-balance fund reconciled at each shift); all cage transactions above defined thresholds require dual-employee verification; electronic funds transfer terminals must have access logs; kiosks (bill-breaking and TITO redemption machines) must be included in daily cage reconciliation
  • § 543.20 — Information technology and data: IT systems supporting gaming operations must have access controls identifying every user; system changes must go through a documented change-control process with approval at appropriate authority levels; gaming system data must be backed up and recoverable; cybersecurity incident response procedures must be documented
  • § 543.21 — Surveillance standards: surveillance systems must cover all gaming floors, cage areas, count rooms, and entry/exit points; surveillance recordings must be retained for a minimum period (30 days under most NIGC guidance); surveillance personnel must be operationally independent of gaming floor staff — the surveillance department reports to management above the gaming floor supervisor level
  • § 543.23 — Audit and accounting: gaming operations must engage an independent CPA for an annual audit of financial statements; the audit must cover compliance with the Class II gaming standards; internal audit functions must be independent of the departments being audited; reconciliation discrepancies above defined materiality thresholds must be investigated and documented

  Part 543's internal controls serve as the operational backbone for Class II gaming integrity — the system by which a tribal gaming facility accounts for every dollar from the moment it enters play to the moment it reaches the tribal government's account. The controls are designed specifically for the Class II gaming environment, where pull-tabs, bingo cards, and electronic bingo aids present different theft and manipulation vectors than Class III slot machines or card tables.

• 25 CFR Part 547 — Minimum Technical Standards for Class II Gaming Systems and Equipment. NIGC technical standards for the electronic and computerized systems that have transformed Class II gaming from paper bingo cards to sophisticated multi-player networked gaming. IGRA § 2703(7)(A)(i) permits use of "electronic, computer, or other technologic aids" in Class II games — Part 547 defines what those aids must do to remain lawful. The distinction matters: a legal Class II electronic aid assists in playing a human-administered game (a networked bingo display where the caller is the game); an illegal Class III simulation runs the game itself (a slot machine dressed up as bingo). Key provisions:

  • § 547.2 — Definitions: the Part defines "Class II gaming system" (the complete hardware-software system for Class II gaming), "random number generator" (RNG), "account access component" (card reader or credential that identifies the player), and "download" (transfer of content to a gaming device); precise definitions matter because they determine whether a device is a permissible Class II aid or an illegal Class III machine
  • § 547.10 — Critical event standards: Class II gaming systems must record fault events (power loss, door open, communication failure) with timestamp and cause; systems must be capable of recovery to a defined state after fault events; unrecoverable faults must generate an alert to gaming floor personnel; the fault logging creates an auditable trail that distinguishes equipment malfunction from tampering
  • § 547.11 — Money and credit handling: credit acceptance must register the correct number of credits immediately upon acceptance; bill validators must reject counterfeits using current currency security features; credits cannot be issued without a corresponding value being received; unclaimed credits (abandoned TITO tickets) must be tracked and remitted under applicable unclaimed property procedures
  • § 547.14 — Random number generation: RNGs must produce output with three properties — statistical randomness (uniform distribution over the range), unpredictability (knowing previous outputs cannot predict future outputs), and non-repeatability (the same seed cannot be reliably reproduced); RNGs must be certified by an independent gaming laboratory approved by the NIGC or Tribal Gaming Regulatory Authority (TGRA); certification tests the mathematical properties of the RNG, not just its software implementation
  • § 547.15 — Data communications security: sensitive data transmitted between Class II gaming system components (between the display device and the bingo server, for example) must be encrypted or otherwise protected against eavesdropping, tampering, and intrusion; the communications security requirement addresses the specific risk of Class II networked games — if the game outcome is determined by a central server, a compromised communication link could allow outcome manipulation
  • § 547.16 — Game artwork, glass, and rules: all rules, prize schedules, and instructions for the Class II game must be displayed or immediately available to the player on request; the displayed rules must be accurate and not misleading; changes to game rules or prize structures require testing and approval before implementation; the transparency requirement ensures players understand the game they are playing — a consumer protection requirement built into the technical standards
  • § 547.17 — Alternate minimum standards: a TGRA may approve alternate technical standards that differ from Part 547 if it determines the alternate standards achieve the same regulatory objective; alternate standards must be submitted to and acknowledged by the NIGC; this flexibility allows TGRAs to approve new gaming technologies that don't fit Part 547's prescriptive requirements without waiting for federal rulemaking

  The technical standards in Part 547 reflect the evolution of Class II gaming from paper bingo cards called by a human announcer to networked electronic gaming systems where multiple players at different locations participate in the same bingo game through digital displays. The line between a Class II electronic bingo aid and a Class III slot machine remains one of IGRA's most commercially significant regulatory distinctions — billions of dollars of gaming revenue and thousands of gaming machines turn on whether a device qualifies as a Class II aid (requiring no state compact) or Class III (requiring a compact and state-level approval). Recent rulemakings: 83 FR 65508 (December 2018) — comprehensive revision of Part 547 updating RNG standards and communications security requirements.

• 25 CFR Part 514 — Fees: the NIGC's annual gaming fee regulation implementing IGRA § 2717 (25 U.S.C. § 2706), which requires every tribal gaming operation under NIGC jurisdiction — including self-regulated tribes holding certificates under Part 518 — to pay annual fees to fund Commission operations. Key provisions:

  • § 514.2 — Publication: the Commission must adopt annual fee rates no later than November 1 of the preceding year and publish them in the Federal Register; gaming operations must know their fee obligation before the fiscal year begins
  • § 514.3 — Maximum statutory rate: fees may not exceed 2.5% of the first $1.5 million in net gaming revenues plus 5% of net revenues above $1.5 million; the cap prevents fees from becoming confiscatory even for the highest-revenue casino operations; the total annual collections cap is set by IGRA and adjusted periodically (approximately $34 million in recent years)
  • § 514.4–514.5 — Calculation and quarterly payment: each gaming operation calculates its fee based on net gaming revenues from the prior calendar year; fees are paid quarterly in equal installments; the quarterly payment structure smooths the cash flow burden for tribal governments that depend on gaming revenue for governmental services
  • § 514.6 — Quarterly statements: each gaming operation must file a quarterly statement of gross gaming revenues with each quarterly fee payment; these statements are the NIGC's primary data source for revenue monitoring and market analysis
  • § 514.9 — Late payment penalty: quarterly payments more than 30 days late are subject to a late fee (assessed as a percentage of the overdue amount)
  • § 514.10 — Failure to pay: statements or payments more than 90 days late constitute a failure to pay under IGRA § 2717(a)(4) — grounds for the NIGC Chair to revoke approval of any gaming license, ordinance, or resolution; the Chair may simultaneously issue a notice of violation and a temporary closure order, immediately shutting down the gaming operation pending resolution
  • § 514.14 — Surplus disposition: if total fee collections across all gaming operations exceed the statutory cap, the Commission must credit the excess proportionally against future assessments; unspent fee revenue at fiscal year-end is similarly returned to gaming operations
  • §§ 514.15–514.17 — Fingerprint processing fees: gaming operations may submit fingerprint cards directly to the NIGC for FBI background check processing as part of the Part 556 key employee licensing process; the Commission charges a separate fingerprint processing fee covering FBI transaction costs plus NIGC administrative expenses; the fee is reviewed annually and published in the Federal Register

  The NIGC fee structure is the financial foundation for all federal Indian gaming oversight. With approximately 520 tribal gaming operations in 29 states generating roughly $40 billion in annual gross gaming revenues, the fee program funds the Commission's ~250 staff, compliance review programs, audit functions, and technology systems. Tribes have historically objected to the fee as an inappropriate tax on governmental gaming revenues — arguing that requiring tribes to fund their own federal regulation is inconsistent with the trust responsibility and government-to-government relationship underlying IGRA. In response to these concerns, Congress capped total NIGC fee collections at a level designed to cover regulatory costs without accumulating surpluses. The temporary closure authority embedded in § 514.10's failure-to-pay provision gives the NIGC significant leverage in fee disputes — the prospect of an immediate casino shutdown creates powerful incentives for rapid payment even while a tribe contests the underlying fee calculation. Recent amendments: 87 FR 54367 (September 2022) — updated fee computation methodology and quarterly statement requirements; 83 FR 2905 (January 2018) — formalized quarterly payment and statement submission processes.

NIGC Monitoring and Investigations (25 CFR Part 571) and Appeals Before a Presiding Official (25 CFR Part 584)

The NIGC exercises oversight through on-site monitoring and investigations of tribal gaming operations, governed by 25 CFR Part 571. When investigations reveal violations, tribes and gaming operators may appeal through a formal adjudicatory process before an independent presiding official, governed by 25 CFR Part 584.

Part 571 — Monitoring and Investigations:

• § 571.1 — Scope: Part 571 sets forth general procedures governing the Commission's monitoring and investigations of Indian gaming operations; monitoring is ongoing and preventive while investigations are initiated in response to specific complaints, tips, or findings
• § 571.12 — Audit standards: each tribe must prepare comparative financial statements covering all financial activities of each Class II and Class III gaming operation, audited in accordance with generally accepted auditing standards (GAAS); audits must be conducted by an independent certified public accounting firm; the audit requirement ensures NIGC has reliable financial data for oversight and for assessing whether gaming revenues are used for tribal governmental purposes as required by IGRA
• § 571.13 — Audit report submission: each tribe must submit two paper copies or one electronic copy of financial statements and audits to the NIGC within 120 days after the end of the gaming operation's fiscal year; operations with gross gaming revenues exceeding $3 million must also submit a report on internal controls; these reports are the NIGC's primary tool for ongoing financial monitoring without requiring inspectors at every facility at all times
• § 571.14 — Notice of violation: when the NIGC Chair finds that a tribe or management contractor has violated IGRA or NIGC regulations, the Chair issues a notice of violation; the notice specifies the violation and a reasonable time (not less than 30 days) to correct the violation; failure to correct can result in civil monetary penalties (up to the inflation-adjusted per-violation cap, ~$65,655 in 2026) or temporary closure orders

Part 584 — Appeals Before a Presiding Official:

• § 584.1 — Coverage: Part 584 governs appeals of NIGC notices of violation and civil penalty assessments where the respondent elects a hearing before a presiding official — an independent administrative law judge or other presiding official designated by the NIGC Chair; the hearing election is an alternative to the shorter Commission-review process under Part 582
• § 584.10 — Settlement: at any time after commencement of a proceeding but at least 5 days before the hearing, parties may pursue settlement or consent decree; settlements must be approved by the Commission; the settlement process provides a structured pathway to resolve disputes without a contested hearing
• § 584.11 — Transcript: hearings with oral presentations are recorded verbatim; transcripts are provided to parties upon request; the transcript requirement supports judicial review and ensures a complete record
• § 584.12 — Recommended decision: within 30 days after the record closes, the presiding official issues a recommended decision; if the subject involves an order for immediate closure, the presiding official must issue the decision within 30 days of being designated; the short deadline reflects the severity of casino closure orders for tribal economies
• § 584.13 — Objections: within 20 days after service of the recommended decision, any party may file objections with the Commission; the Commission then reviews the recommended decision and objections and issues a final decision; final Commission decisions are subject to judicial review in federal district court

Parts 571 and 584 form the enforcement backbone of IGRA's federal oversight framework — Part 571's audit and monitoring tools detect compliance issues, and Part 584's adjudicatory process ensures tribes can contest NIGC enforcement actions before a neutral decision-maker. The compressed timelines throughout (30 days for recommended decisions, 20 days for objections) reflect the economic urgency of Indian gaming — casino closure orders can cost tribal governments millions of dollars per day and directly affect the governmental services funded by gaming revenues.

NIGC Gaming Ordinance Submission and Approval (25 CFR Part 522)

Before any Class II or Class III gaming can begin on Indian lands, the tribe must adopt a gaming ordinance or resolution and submit it to the NIGC Chair for approval. 25 CFR Part 522 governs this pre-authorization process — the gateway requirement that ensures tribal gaming governance meets IGRA's minimum standards before gaming commences.

• § 522.1 — Scope: Part 522 applies to any Class II or Class III gaming ordinance or resolution, or amendment thereto, adopted by a tribe; no gaming may begin until the ordinance is approved or deemed approved by operation of law
• § 522.2 / § 522.3 — Submission requirements: the tribe must submit the ordinance or resolution to the NIGC Chair along with documentation showing adoption by the tribal governing body; for Class III gaming, the tribe must also have a Tribal-State compact in place (or a compact has been deemed approved); the Chair reviews the submission for compliance with IGRA's minimum standards (tribal ownership, use of gaming revenues for governmental purposes, background checks for key employees)
• § 522.10 — Approval by operation of law: if the Chair fails to approve or disapprove the ordinance within 90 days of submission, the ordinance is deemed approved by operation of law; this 90-day automatic approval provision prevents NIGC delays from indefinitely blocking tribal gaming and creates an administrative deadline that forces timely NIGC action
• § 522.11 — Individually owned Class II gaming (post-September 1986): for gaming operations that are not tribally owned (i.e., individually owned enterprises on Indian lands), the ordinance must include additional provisions for licensing the individual operators and ensuring tribal governmental control; IGRA's preference for tribally owned gaming means individually owned operations face more stringent requirements
• § 522.12 — Individually owned Class II gaming (pre-September 1986 operations): operations that were individually owned and in operation before September 1, 1986, receive grandfather treatment under IGRA and may continue under tribal licensing without meeting the post-1986 standards, subject to background investigation and tribal ordinance requirements
• § 522.13 — Revocation of Class III gaming: a tribal governing body may, in its sole discretion and without NIGC approval, adopt an ordinance or resolution revoking any prior authorization of Class III gaming; this tribal authority to self-limit reflects IGRA's government-to-government framework — tribes cannot be forced to conduct gaming and retain unilateral authority to exit the gaming business

The gaming ordinance approval process is the foundational IGRA compliance step: it establishes that a tribe has adopted the governance framework (including use of gaming revenues for governmental purposes, NIGC audit access, key employee licensing, and exclusion of persons convicted of felonies) that IGRA requires as a condition of gaming. Without an approved ordinance — or an ordinance deemed approved by the 90-day rule — any gaming is illegal under IGRA. Tribes sometimes use the 90-day approval-by-operation-of-law provision strategically when the NIGC Chair is slow to act, submitting an ordinance with the expectation that the Chair's failure to act within 90 days will result in automatic approval. Recent rulemaking: 87 FR 54367 (September 2022) — updated Part 522 to align with new NIGC definitions regulations.

NIGC Appeal Proceedings — General Rules (25 CFR Part 580)

25 CFR Part 580 establishes the procedural rules applicable across all NIGC appeal proceedings — the general framework governing how parties appeal NIGC Chair decisions to the full Commission. Parts 582 through 585 govern the specific types of appeals (civil fines, temporary closure orders, license appeals, key employee suitability determinations); Part 580 sets the baseline rules that apply to all of them.

• § 580.3 — Representation: any party may appear in person, through an attorney, or through any other representative of their choice; unlike some federal proceedings, NIGC appeals do not require attorney representation — tribes may designate a tribal official or advisor
• § 580.4 — Service: the appellant must serve notice of appeal on the Commission at the address in the decision being appealed, and on all other parties; service may be by overnight courier, hand delivery, fax, or email if the receiving party has consented to electronic service
• § 580.5 — Consequences of failure to file: failure to file an appeal within the prescribed time period waives the right to appeal; failure to file a required brief or meet other deadlines may result in the appeal being dismissed — a significant consequence for gaming operations where a closure order is pending
• § 580.7 — Burden of proof and standard of review: the Chair bears the burden of proof by a preponderance of the evidence to support any action the Chair has taken — an unusual procedural posture where the agency official defending the decision must affirmatively demonstrate its correctness, not just show it was not arbitrary; the standard of review for legal conclusions is de novo (the Commission applies fresh legal analysis); the standard of review for factual findings is also de novo, allowing the Commission to make independent factual determinations
• § 580.10 — Finality: the Commission's decision is the final agency action for purposes of judicial review; once the Commission has issued its decision (or the Chair's decision stands due to lack of a majority under § 580.11), the only remaining avenue is federal court review under the APA arbitrary-and-capricious standard
• § 580.11 — No-majority decisions: if the Commission cannot achieve a majority decision within the time provided, the Chair's original decision becomes the final agency action; this prevents indefinite delays in gaming operations pending Commission deliberation — the operational stakes (casinos generating revenue vs. closure orders) demand timely resolution
• § 580.12 — Stay of appeals: filing an appeal does not automatically stay the effect of the Chair's decision, except as provided in Parts 522 (gaming ordinance appeals) and similar provisions; gaming operations subject to a temporary closure order are not automatically continued just because an appeal is filed — the Commission or a court must affirmatively grant a stay

Part 580's de novo review standard is significant: it means the Commission does not give deference to the Chair's interpretation of IGRA or NIGC regulations. Each Commissioner reviews the legal and factual record independently. This framework allows the Commission — which includes members with diverse backgrounds including tribal representatives — to provide a genuine second look at enforcement actions that may have major economic consequences for tribal governments.
