SORNA and State Law

Here is an interesting decision from the Supreme Court on the interplay between SORNA and Montana state law. The Ninth Circuit ruled that the federal juvenile registration provision were ex post facto as applied to respondent. Respondent remains on Montana's sex offender registry; the Supreme Court certified a question that could resolve whether he must continue to register under state law independent of the fact that his federal duty to register expired in 2008, and might also violate the Ex Post Facto Clause (does, according to the Ninth).
