John Doe v. Eric T. Olson

Summary

The Court affirmed the judgment rejecting Doe’s substantive due process and ex post facto challenges to Missouri’s sex-offender registration requirements. It held Doe had no fundamental privacy right in information concerning convictions that were admitted in open court and later sealed, and that the registry is rationally related to protecting children. It also held that the registration scheme remains civil and regulatory rather than punitive despite later amendments imposing lifetime registration, tiering, in-person reporting, DNA collection, and expanded online disclosure.
