HRA submitted an expert report and provided deposition testimony in a case involving the history of land ownership and road development in the Big Arm Townsite on the Flathead Indian Reservation. Established under a 1906 amendment to the Flathead Allotment Act, Big Arm was one of nearly two dozen townsites created under congressional authority within the reservation. In addition to analyzing the sale of town lots and the elimination of lands from the townsite, HRA investigated whether any historical evidence showed that county officials complied with federal and state rights-of-way laws that were in effect during the early 1900s. In April 2020, the U.S. District Court ruled in favor of the Confederated Salish and Kootenai Tribes (CSKT), citing portions of HRA’s report in the ruling.
