Whenever the Commission
has reason to believe that the tribal operator of an Indian
game or a management contractor is engaged in activities regulated by this chapter, by regulations prescribed under this chapter, or by tribal regulations, ordinances, or resolutions, approved under section 2710
of this title, that may result in the imposition of a fine under subsection (a)(1), the permanent closure of such game, or the modification or termination of any management contract,
shall provide such tribal operator or management contractor with a written complaint stating the acts or omissions which form the basis for such belief and the action or choice of action being considered by the Commission.
The allegation shall be set forth in common and concise language and must specify the statutory or regulatory provisions alleged to have been violated, but may not consist merely of allegations stated in statutory or regulatory language.
