Limited. Still binding in Alaska (State v. Doe A, 2013), but the court later declined to extend it to people convicted elsewhere who move to Alaska (2019). Final word on that state’s own law and constitution — in that state only.
What happened
The plaintiff was one of the two men in Smith v. Doe. He had pleaded no contest in 1985 and was released in 1990, before Alaska’s registration act took effect on August 10, 1994. Having lost under the federal Constitution, he challenged the act under Alaska’s.
What the court decided
By 2–1, the court held that the act’s effects are punitive under the Alaska Constitution’s ex post facto clause (art. I, § 15), so its registration requirements cannot apply to people who committed their crimes before August 10, 1994. The court assumed, without deciding, that the legislature meant the law to be civil.
Why it matters to the Registry
It is the clearest example that a win for the state in the U.S. Supreme Court does not end the question: the same law, judged by the same kind of test under a state constitution, came out the other way.
What it did not decide
It is a state-law ruling only; Smith v. Doe still controls the federal question. It protects people whose offenses predate the act in Alaska, not people convicted in other states who later move there.
