83.3—Scope.

(a) This part applies only to those American Indian groups indigenous to the continental United States which are not currently acknowledged as Indian tribes by the Department. It is intended to apply to groups that can establish a substantially continuous tribal existence and which have functioned as autonomous entities throughout history until the present.
(b) Indian tribes, organized bands, pueblos, Alaska Native villages, or communities which are already acknowledged as such and are receiving services from the Bureau of Indian Affairs may not be reviewed under the procedures established by these regulations.
(c) Associations, organizations, corporations or groups of any character that have been formed in recent times may not be acknowledged under these regulations. The fact that a group that meets the criteria in § 83.7 (a) through (g) has recently incorporated or otherwise formalized its existing autonomous political process will be viewed as a change in form and have no bearing on the Assistant Secretary's final decision.
(d) Splinter groups, political factions, communities or groups of any character that separate from the main body of a currently acknowledged tribe may not be acknowledged under these regulations. However, groups that can establish clearly that they have functioned throughout history until the present as an autonomous tribal entity may be acknowledged under this part, even though they have been regarded by some as part of or have been associated in some manner with an acknowledged North American Indian tribe.
(e) Further, groups which are, or the members of which are, subject to congressional legislation terminating or forbidding the Federal relationship may not be acknowledged under this part.
(f) Finally, groups that previously petitioned and were denied Federal acknowledgment under these regulations or under previous regulations in part 83 of this title, may not be acknowledged under these regulations. This includes reorganized or reconstituted petitioners previously denied, or splinter groups, spin-offs, or component groups of any type that were once part of petitioners previously denied.
(g) Indian groups whose documented petitions are under active consideration at the effective date of these revised regulations may choose to complete their petitioning process either under these regulations or under the previous acknowledgment regulations in part 83 of this title. This choice must be made by April 26, 1994. This option shall apply to any petition for which a determination is not final and effective. Such petitioners may request a suspension of consideration under § 83.10(g) of not more than 180 days in order to provide additional information or argument.
