In an earlier article, we argued that the Utah Supreme Court failed to follow and correctly apply clear U.S. Supreme Court precedent in Steiner v. Utah when the Utah high court held that an internally inconsistent and discriminatory state tax regime did not violate the dormant commerce clause. Unfortunately, the Supreme Court recently declined certiorari in Steiner, but the issue is unlikely to go away. Not every state high court will defy the U.S. Supreme Court by refusing to apply the dormant commerce clause, and so the Court will sooner or later likely find itself facing conflicting interpretations of the dormant foreign commerce clause. Accordingly, in this article we address an issue that we did not cover in our earlier article: how Utah could revise its tax system to satisfy the Constitution.
