Whether Congress intended the 1991 “Duro fix” to recognize inherent tribal authority, rather than delegate federal authority, to prosecute nonmember Indians.
Holding
Yes. Congress intended to recognize and affirm tribes’ inherent criminal jurisdiction over all Indians, including Indians who are not members of the prosecuting tribe.
Reasoning
The Indian Civil Rights Act defines tribal “powers of self-government” to include “the inherent power of Indian tribes, hereby recognized and affirmed, to exercise criminal jurisdiction over all Indians.” The Court read that language as affirming an existing sovereign source of tribal authority, not as transferring the Federal Government’s own prosecutorial power to tribal courts.
The legislative history reinforced the statutory text. Congressional reports and statements repeatedly described the amendment as a clarification or reaffirmation of inherent tribal authority, expressly disclaiming an intent to delegate federal jurisdiction. Thus, the Spirit Lake Tribe prosecuted Lara under claimed tribal authority, not as an agent of the Federal Government.
