The Washington state Supreme Court granted last year the Yakama Nation the right to transport goods and services across state lines without taxation.
Attorneys and tribal members called it a landmark case for tribal sovereignty, and now the U.S. Supreme Court has agreed to review it.
In 2013, Washington’s Department of Licensing demanded $3.6 million in taxes and fees from a Yakama Nation fuel company, so the two parties went to court.
A Yakama Nation member transported fuel across the Oregon-Washington border for sale at the Cougar Den — a gas station on the tribe’s reservation.
He said a unique travel clause in a treaty signed with the U.S. government in 1855 exempted him from state taxes.
Only two other tribal treaties in the Northwest expressly outline the right to travel.
The high court will consider this fall whether the treaty allows tribal members to avoid state taxes when they transport goods on public highways.
Five other states filed amicus briefs in favor of Washington’s petition for review.
