Gorsuch, J., concurring in judgement
entitled to move that good tax-free from market back to the reservation. But that is hardly anomalous–that is the treaty right the Yakamas reserved. And it’s easy to see why. Imagine the Yakama Reservation reached the Washington/Oregon state line (as it did before the 1855 Treaty). In that case, Washington would have no basis to tax the Yakamas’ transportation of goods from Oregon (whether they might be fuel, mink coats, or anything else), as all of the Yakamas’ conduct would take place outside of the State or on the reservation. The only question here is whether the result changes because the Tribe must now use Washington’s highways to make the trek home. And the answer is no. The Tribe bargained for a right to travel with goods off reservation just as it could on reservation and just as it had for centuries. If the State and federal governments do not like that result, they are free to bargain for more, but they do not get to rewrite the existing bargain in this Court.
Alternatively yet, the State warns us about the dire consequences of a ruling against it. Highway speed limits, reckless driving laws, and much more, the State tells us, will be at risk if we rule for the Tribe. See also post, at 7–10 (Roberts, C. J., dissenting). But notice. Once you acknowledge (as the State and primary dissent just have) that the Yakamas themselves enjoy a right to travel free of at least some nondiscriminatory state regulations, this “problem” inevitably arises. It inevitably arises, too, once you concede that the Yakamas enjoy a right to travel freely at least on local roads. See post, at 3 (Kavanaugh, J., dissenting). Whether you read the treaty to afford the Yakamas the further right to bring goods to and from market is beside the point.
It turns out, too, that the State’s parade of horribles isn’t really all that horrible. While the treaty supplies the Yakamas with special rights to travel with goods to and from market, we have seen already that its “in common
