State courts question mandatory lifetime sex offender registration
Notwithstanding the Supreme Court’s decisions in Connecticut Department of Public Safety v. Doe, 538 U.S. 1 (2003) and Smith v. Doe, 538 U.S. 84 (2003), state courts are coming to different conclusions under their own constitutions about whether sex offender registration and notification laws constitute punishment for purposes of due process and ex post facto analysis. The Pennsylvania Supreme Court is the most recent to invalidate mandatory registration requirements imposed on juveniles, but several state supreme courts have limited the retroactive application of registration requirements to adults under an ex post facto analysis.
