you mean this one ?
On October 29, 2007, Oglala Sioux Tribe (OST) Chief Judge Lisa Adams issued an exclusion order to remove the Native American Energy Group external link (N.A.E.G.) from the Pine Ridge reservation, declaring that the company has been trespassing on tribal lands. The finding gave NAEG 30 days to vacate the reservation.
The Judge also noted that N.A.E.G. ignored a tribal resolution that accepted the OST Environmental Technical Team's recommendation that the Tribe not enter into any working relationship with N.A.E.G. Further, the order stated that OST Member, Eileen Janis, failed to inform N.A.E.G. about OST ordinances prohibiting exploration and mining for uranium.

Or do you mean the time they got literally Chased off a reservation, (which i believe i recall was a different res. but i'd have to dig up old files to confirm)
