Michigan's sex offender registry has been struck down as unconstitutional. It's the result of multiple legal battles, tracing all the way back to 2010. The latest round of litigation has finally killed the law -- something legislators allowed to stay on the books after being told pretty much the same thing by the Sixth Circuit Court of Appeals in 2016.

If you really want to dig into the details of this years-long attempt to overturn the law, you really should read Guy Hamilton-Smith's guest post at Simple Justice. He quotes the Sixth Circuit's 2016 opinion, which really should have resulted in something better than the state offered in response, which was nothing. Due process isn't something very many sex offender registries do well, and Michigan's SORA was one of the worst.
