Report A Violation

Helpful Hints for Reporting suspect IGRA Violations to the NIGC Division of Compliance  

I. Introduction

The National Indian Gaming Commission (NIGC) wants to ensure information is being reported to the correct entity with jurisdiction over your matter. Please take a minute and read the following information before reporting a suspected Indian Gaming Regulatory Act (IGRA) violation to the NIGC. The United States Congress enacted IGRA on October 17, 1988, to regulate the conduct of gaming on Indian lands. IGRA establishes the NIGC and the regulatory structure for Indian gaming in the United States.

IGRA has the following purpose:

(1) To provide a statutory basis for the operation of gaming by Indian tribes as a means of promoting tribal economic development, self-sufficiency, and strong tribal governments;

(2) To provide a statutory basis for the regulation of gaming by an Indian tribe adequate to shield it from organized crime and other corrupting influences, to ensure that the Indian tribe is the primary beneficiary of the gaming operation, and to assure that gaming is conducted fairly and honestly by both the operator and players; and

(3) to declare that the establishment of independent Federal regulatory authority for gaming on Indian lands, the establishment of Federal standards for gaming on Indian lands, and the establishment of a National Indian Gaming Commission are necessary to meet congressional concerns regarding gaming and to protect such gaming as a means of generating tribal revenue.

Tribes are the primary regulators of their gaming operations. The NIGC’s primary focus is to monitor tribal gaming facilities, provide technical assistance and training, and support the work of tribal gaming regulators. In doing so, the Commission, through its Compliance Division, conducts routine site visits at tribal gaming facilities and performs audits to monitor compliance with the IGRA, NIGC regulations and tribal gaming ordinances or resolutions approved by the NIGC Chair. The NIGC can provide training and technical assistance both in person and remotely.

Through monitoring, audits and the use of technical assistance and training provided by the NIGC, the Tribes address the majority of non-compliance violations voluntarily. Serious, repetitive or willful violations may be addressed by the Chief Compliance Officer through the issuance of a letter of concern to the Tribe detailing the NIGC’s concerns regarding compliance with the IGRA, NIGC regulations, and/or tribal gaming ordinance or resolutions. A letter of concern describes the available facts and information, includes a preliminary assessment regarding the incident or condition, and provides a time period for the violator to respond.

Violations may further be addressed by the NIGC Chair through the issuance of a notice of violation, temporary closure order and civil fine for violations of any provision of the IGRA, NIGC Regulations, or of any tribal ordinance or resolution. The Chair’s discretion to take enforcement action is not limited or constrained on whether or not a letter of concern was issued.

Violations of the IGRA, NIGC Regulations or tribal gaming ordinance or resolution may include:

  • When the tribe does not maintain sole proprietary interest and responsibility for the conduct of any gaming activity (Please see NIGC Bulletin No. 2021-6 Sole Proprietary Interest at
  • When net revenues1 from any tribal gaming are used for purposes other than to fund tribal government operations or programs, to provide for the general welfare of the Indian tribe and its members, to promote economic development, to donate to charitable organizations, and to help fund operations of local government agencies;
  • If the construction and maintenance of the gaming facility and the operation of gaming is conducted in a manner that does not adequately protect the environment and the public health and safety; and
  • If tribes and/or gaming operations do not develop and implement internal controls to protect the integrity of gaming and protect tribal assets. 
II. Report Processing

Upon receipt of a specific allegation of a violation, the NIGC will evaluate the information to determine jurisdiction over the matter and whether the NIGC needs to take any one of the following actions:

  • Open an investigation, or perform an audit or inspection;
  • Refer the matter to the tribal gaming regulator for appropriate review and action; or
  • Refer the allegation to another Federal agency or other law enforcement authority with jurisdiction over the matter. 

Allegations with limited specificity or merit may be held in abeyance until further, specific details are reported, or it may be determined that the matter be dismissed.

Jurisdiction: The IGRA provided for distinct jurisdictions over matters involving tribal gaming. Tribes are the primary regulators and have jurisdiction and responsibility to regulate Class I, II, and III gaming.  NIGC shares jurisdiction with the tribes over all Class II matters and limited Class III matters. The Tribes and State share jurisdiction over Class III matters related to Class III internal controls, compacted games, and patron disputes arising from compacted games. The United States Attorney has jurisdiction over criminal matters involving tribal gaming. Additionally, the Tribes, Department of Interior – Office of Indian Gaming, and NIGC have jurisdiction over specific matters involving tribal-state gaming compacts and revenue allocation plans (per capita payments). 

III. Prize Claims and Patron Disputes

To determine whether a tribe has jurisdiction for a potential prize claim or patron dispute, first, ask yourself did the event occur at a gaming operation licensed by a federally recognized tribe or is it on a tribe's Indian lands as defined by IGRA. If it is not, you may need to contact the state’s gaming authority where the operation is located. It is important to understand that if you have a patron dispute regarding a prize claim that you should first attempt to resolve the issue by contacting the management of the casino where the event occurred.  You must obtain a copy of the prize claim or dispute procedures from the casino or tribal gaming regulatory authority/tribal gaming commission. Be sure to follow the procedure by filing your claims with the tribal entity identified timely and in the manner prescribed in the procedure.  If casino management does not resolve the dispute, you should next contact the tribe’s gaming commission or tribal gaming regulatory authority in accordance with their procedure.  If you report this event to the NIGC, in most cases, the NIGC will refer the matter to the tribal gaming regulator to investigate.  Each tribe is required under NIGC regulations to include a copy of their prize claim dispute procedures with any tribal gaming ordinance submitted to the NIGC Chair for approval. Some tribes include the process or part of the process in their tribal gaming ordinance. In instances where the tribe offers Class III gaming under a tribal-state gaming compact, the process may be addressed in the gaming compact. 

The NIGC will investigate those matters where the patron was denied the opportunity to file a claim through the tribe’s procedure. Typically, this includes instances where there is no process established or if there is evidence of fraud. The NIGC will not interrupt or intervene on behalf of a patron during the tribe’s dispute process. Filing a report or claim outside of the tribe’s process may void your claim under the tribe’s rules. Please review the tribe’s procedures in full before reporting the matter to the NIGC.  

IV. Complaints May Remain Anonymous
