ITG FAQ #9 Answer-How is Indian gaming regulated?
The primary regulator of an Indian casino is the tribal gaming regulatory agency (TGRA), or Tribal Gaming Commission. Secondary regulation depends upon the following:
1) Whether the tribe has negotiated a Class III compact with its state;
2) The language of the Tribal-State compact as to regulatory duties.
3) If no Tribal-State compact exists, NIGC assumes secondary regulatory duty.
