In 2003, the United States Supreme Court issued its only two opinions regarding the constitutionality of sex offender registration and notification statutes. Smith v. Doe ("Smith") and Connecticut Department of Public Safety v. Doe ("DPS"), upheld the Alaska and Connecticut registry and notification laws against Ex Post Facto Clause and procedural due process challenges. Three years later, the Federal Sex Offender Registration and Notification Act ("SORNA") was passed as part of the Adam Walsh Child Protection and Safety Act. The federal statute was very different from the state statutes that the Court reviewed. Most notable among the differences was the creation of the federal crime of "failure to register" which was punishable by up to ten years imprisonment. This article contends that most district courts have been severely misguided in reading the two Court opinions and the statutory provisions of SORNA. Consequently, this article concludes that either Congress should amend SORNA or courts should strike down portions of SORNA on Ex Post Facto Clause, procedural due process, and Commerce Clause grounds.
