United States v. Abouselman, No. 18-2164 (10th Cir. 2020)Annotate this Case
The Pueblos of Jemez, Santa Ana, and Zia resided along the Jemez River at a time when their lands passed from Spanish to Mexican sovereignty, and finally to the United States. In 1983, the United States initiated a water-rights adjudication for the Jemez River Basin, claiming water rights on behalf of the Pueblos. The issue this case presented for the Tenth Circuit's review centered on whether the Pueblos' aboriginal water rights were extinguished by the imposition of Spanish authority "without any affirmative adverse act." No matter the method used, the sovereign’s intent to extinguish must be clear and unambiguous; “an extinguishment cannot be lightly implied in view of the avowed solicitude of the Federal Government for the welfare of its Indian wards.” Moreover, “if there is doubt whether aboriginal title has been validly extinguished by the United States, any ‘doubtful expressions, instead of being resolved in favor of the United States, are to be resolved in favor of’ the Indians.” The Tenth Circuit reversed the district court, finding that while "All conquering sovereigns possess authority over their land and resources ... not until the sovereign exercises this authority through clear and adverse affirmative action may it extinguish aboriginal rights."
