(United States Supreme Court) - This case involved the State of Washington's tax on fuel importers who travel by public highway. The Yakama Nation contended that its 1855 treaty with the United States forbids that tax from being imposed upon fuel importers who are tribal members. The U.
S. Supreme Court agreed with the tribe. Justice Breyer's plurality opinion was joined by only two other justices. Justices Gorsuch and Ginsburg concurred in the judgment.
