(a) OFA reviews the documented petition for previous Federal acknowledgment during the Phase II technical assistance review of the documented petition.

(b) If OFA cannot verify previous Federal acknowledgment during this technical assistance review, the petitioner must provide additional evidence. If a petitioner claiming previous Federal acknowledgment does not respond or does not demonstrate the claim of previous Federal acknowledgment, OFA will consider its documented petition on the same basis as documented petitions submitted by petitioners not claiming previous Federal acknowledgment.
