While the Supreme Court regularly decides cases defining the limits of the criminal jurisdiction of tribal courts, when it heard United States v. Cooley in 2021 it had not decided a case about the procedural powers of tribal law enforcement in more than a century. Across more than five decades lower courts at all levels struggled to decide whether the inherent criminal powers of tribal law enforcement are coterminous with the jurisdiction of tribal courts or whether tribal officers may have their own set of inherent powers distinct from the power to prosecute. This Article examines the inconsistent split in authority that existed before Cooley and anticipates the future misreading of inherent criminal power by lower courts. It argues that now that the Court has divorced the inherent criminal power of tribal law enforcement from the criminal jurisdictional power of tribal courts, tribal officers may stop, detain, search, and investigate anyone whose criminal conduct poses a danger to the health and welfare of the tribal community. The Article bolsters its application by using the first cases decided by lower courts in the post-Cooley era as artifacts to examine the full implications of the recognition of inherent criminal power exercised by tribal law enforcement.

This article looks at the enforceability of the Extradition Clause in the federal courts of the United States. In 1861 the Supreme Court held in Dennison that the federal courts could not be used to enforce a request made by one state governor to another state governor for the extradition of a suspected criminal under Article IV Section 1. In 1987 the Supreme Court reversed the Dennison decision and for the first time since the Civil War held that the federal judicial power includes the power to enforce the Extradition Clause. This article takes the position that federal judicial power is limited to cases where the state governor has both territorial and personal jurisdiction over the accused. When an individual is on an Indian reservation, even Article IV does not authorize the governor of a state to enter the reservation and return the accused subject to an extradition request. Article IV’s Extradition Clause provides a constitutional duty for the executive of one state to remit to the power of a sister state someone located within its borders and subject to its jurisdiction. Critical to the exercise of this power is the dual understanding that the individual sought must be both within the state territory and subject to the state’s jurisdiction. Indian country lies outside the general jurisdictional power of the states. States may not enter Indian country and remove persons found there absent cooperation with or permission from the Tribe. Doing so infringes upon the Tribe’s right to make its own laws and be governed by them.
