Adam Crepelle has published “Applying the Indian Commerce Clause to Indian Commerce” in the Northwestern University Law Review.

Here is the abstract:

Indian country commerce generates tens of billions of dollars annually and is a constant source of litigation. These disputes typically revolve around jurisdictional conflicts: whether states, tribes, or both possess regulatory authority over the business operating in Indian country, particularly those involving non-Indians. Despite numerous court cases, no clear legal framework has emerged, creating pervasive uncertainty regarding fundamental issues, such as state taxation of tribal transactions and the proper forum for resolving Indian country contract disputes. Interestingly, these commercial cases overlook the Indian Commerce Clause—the constitutional provision designed to address such matters.

This Article argues the Indian Commerce Clause prohibits state regulation of Indian country commerce. The clause’s plain text and original understanding support this interpretation. While the Supreme Court departed from this understanding in the late 19th century, it has never adequately justified this shift. During the 1980s, the United States argued the Indian Commerce Clause bars state taxation of tribal commerce, and the Supreme Court rejected this argument with scant judicial reasoning. Consequently, courts continue to rely on ambiguous, fact-specific tests that undermine tribal sovereignty and economic development.

This Article proposes a revitalized application of the Indian Commerce Clause, advocating for a clear, constitutionally grounded framework. By categorically preempting state intrusion into Indian country commerce, this approach would provide the certainty necessary for tribal economic self-determination to flourish. This Article demonstrates how such a framework would resolve the current jurisdictional chaos, offering specific guidance for its implementation and ultimately promoting a more just and equitable relationship between tribes and states.
