Introduction

The United States Supreme Court case Washington State Department of Licensing v. Cougar Den, Inc. (139 S. Ct. 1000, 2019) addresses the intersection of state taxation and federally recognized tribal treaty rights. The dispute arose when the Washington State Department of Licensing imposed a substantial fuel tax on Cougar Den, Inc., a wholesale fuel importer operating under the Yakama Nation. Cougar Den contested the tax, asserting that it was pre-empted by an 1855 treaty between the United States and the Yakama Nation, which reserved certain rights to the tribe, including the right to travel on public highways "in common with citizens of the United States."

Summary of the Judgment

The Supreme Court affirmed the lower court's decision, holding that the Washington State fuel tax imposed on Cougar Den, Inc. was pre-empted by the 1855 treaty with the Yakama Nation. The Court concluded that the tax burdened the Yakamas' reserved right to travel with goods on public highways, thereby conflicting with the treaty's provisions. The ruling emphasized that treaties with federally recognized tribes constitute federal law, which takes precedence over conflicting state laws, especially when state actions impede treaty-protected rights.

Analysis

Precedents Cited

The judgment extensively referenced prior Supreme Court cases to substantiate its reasoning:

• UNITED STATES v. WINANS (198 U.S. 371, 1905): Established that treaty rights must be interpreted based on the tribes' understanding at the time of signing.
• TULEE v. WASHINGTON (315 U.S. 681, 1942): Held that state-imposed fees on treaty-protected fishing rights were pre-empted as they burdened the inviolable rights reserved by the treaty.
• Seufert Brothers Co. v. United States (249 U.S. 194, 1919): Reinforced the principle that treaties protect specific rights of tribes beyond common citizen rights.
• Washington v. Washington State Commercial Passenger Fishing Vessel Association (443 U.S. 658, 1979): Affirmed that reserved rights under treaties are protected from state regulation even when state laws are non-discriminatory.
• Oklahoma Tax Commission v. Chickasaw Nation (515 U.S. 450, 1995): Stressed that the interpretation of tax incidence is a question of state law, bound by state court interpretations.

These precedents collectively underpin the Court's stance that treaty rights have enduring and specific protections that supersede state laws when conflicts arise.

Legal Reasoning

The Court's legal reasoning was multifaceted:

1. Treaty Interpretation: The key clause in the 1855 treaty—"the right, in common with citizens of the United States, to travel upon all public highways"—was interpreted based on the Yakama Nation's understanding at the time of signing. The Court emphasized that "in common with" should not be read to merely mean equality in status but to reflect substantive rights as understood by the tribe.
2. Pre-emption Doctrine: As treaties hold federal authority, any state law that conflicts with treaty rights is pre-empted. Here, Washington's fuel tax was found to burden the Yakamas' right to transport goods freely, which the treaty explicitly reserved.
3. Burden on Reserved Rights: The tax was not merely a regulation but an exaction that imposed a financial burden on the exercise of a reserved right. This aligned with the Court's stance in cases like Tulee, where state-imposed fees were invalidated for burdening treaty rights.
4. Historical Context: The Court delved into the historical negotiations of the treaty, highlighting the Yakamas' reliance on public highways for trade and the assurances given by the United States, reinforcing that any state interference encroaches upon these treaty-guaranteed liberties.

By synthesizing these elements, the Court determined that Washington's fuel tax was incompatible with the treaty's protections and thus was invalid as applied to Cougar Den.

Impact

The decision has profound implications:

• Strengthening Tribal Sovereignty: Reiterates the supremacy of federal treaties over state laws, thereby reinforcing tribal sovereignty and ensuring that reserved rights are protected from state encroachments.
• State Taxation Limits: Clarifies the boundaries within which states can impose taxes on tribal entities, especially when such taxes conflict with treaty-protected activities.
• Legal Precedence for Future Cases: Establishes a clear precedent for interpreting similar clauses in other treaties, providing a framework for analyzing potential state-tribe conflicts in areas like transportation, trade, and resource management.
• Economic Implications: For tribal businesses, this ruling affirms the ability to operate without undue financial burdens from state taxes that infringe upon treaty rights, potentially encouraging economic development within tribal nations.
