History of Fort Hall Indian Reservation and Shoshone-Bannock Tribes

The Fort Bridger Treaty of 1868 treaty was entered into between the United States government and the Eastern Band of Shoshone Indians (known at the time as the “Washakie Band”) and the Bannock Indians. This treaty constitutes the starting point for defining the legal relationship between the federal government, the Tribes, and state and local agencies. The Fort Hall Indian Reservation was created by executive order pursuant to the provisions of the 1868 treaty.

The Idaho laws regarding jurisdiction on the Fort Hall Indian Reservation are set forth in Title 67, Chapter 51 of the Idaho Code &  Article XXI, Section 19 of the Idaho Constitution.


The state of Idaho has concurrent jurisdiction over certain matters on the Fort Hall Indian Reservation. This jurisdiction arises from Idaho’s assumption of jurisdiction under a Congressional Act known as Public Law 280. Under that federal law, certain states were allowed to assume jurisdiction in Indian country. Idaho was one of those states that elected to assume jurisdiction. Pursuant to Public Law 280, Idaho adopted Idaho Code 67-5101. That statute gives the state jurisdiction over Indians for the areas of: compulsory school attendant, juvenile delinquency and youth rehabilitation, dependent, neglected and abused children, insanities and mental illness, public assistance, domestic relations, and the operation and management of motor vehicles upon highways and roads maintained by the county or state, or political subdivisions thereof.

Public Law 280 did not require the consent of the Tribes in order for the state to assume jurisdiction. In assuming jurisdiction, the state of Idaho did not request or obtain the consent of the Tribes. This failure to obtain consent, although not required by Public Law 280, is a primary points of contention with tribal members regarding the exercise of state jurisdiction on the Reservation. Some tribal members consider this a legal/sovereignty issue, some see it as a respect issue, and some see it as both.

The Tribes and the state and local governments constantly struggle to define their legal relationship with one another. The federal law on Indian affairs is frequently ambiguous or seemingly-contradictory, rather than clear and consistent. This is primarily a result of the radical changes in policy towards Indians throughout the history of the United States. The legal decisions tend to be heavily influenced by the prevailing policy goals of the federal government at the time the decisions were made. Because of the lack of clear federal statutes and consistent case law, the various Indian tribes and the state and local governments are often left to themselves to attempt to reach a workable resolution to jurisdictional issues.

The federal government is responsible for protecting and securing the rights of the Indians which arise from treaties which were entered into between the federal government and the tribes. Because the federal government is entrusted with providing this protection, it is frequently stated that the federal government has a “trust relationship” with the Indian tribes. The United States Attorney’s Office is assigned the responsibility of overseeing the preservation and protection of these Indian rights and federal obligations. However, the Tribes are also entitled and empowered to take action, including bringing legal suits, to preserve and protect these rights and enforce these obligations.


There are currently no memorandums of understanding to display.

The Shoshone-Bannock Business Council is currently engaged in discussions with the Bannock County Prosecuting Attorney and the Bannock County Sheriff regarding the exercise of state jurisdiction over traffic laws within the Fort Hall Reservation boundaries. The primary component of the proposed memorandum of understanding is a request by the Tribes that enrolled tribal members be allowed the option of having their traffic offenses litigated in Tribal Court, rather than State Court, when the offense occurred on the Reservation. Power County has already agreed to such an arrangement. The Business Counsel is still engaged in discussions with Caribou County and Bingham County.


The Idaho Supreme Court has placed a link to the Tribal/State Court Forum – Benchbook on their website. The benchbook is the product of the Tribal/State Forum’s Benchbook Subcommittee. It discusses the laws and customs of the various Indian tribes residing in Idaho as well as identifying the lawyers admitted to practice before the various Tribal Courts. It outlines the tribal court systems and their relationship with other jurisdictions, including citations to these and other related topics. It also lists the names, addresses, and other information about the various Indian Tribes.
