United States v. Kebodeaux
United States Supreme Court
133 S.Ct. 2496 (2013)
Under the 1994 Wetterling Act and the later Sex Offender Registration and Notification Act (SORNA), Congress required certain convicted sex offenders, including military members, to register their addresses with state authorities. Anthony Kebodeaux (defendant), an Air Force servicemember convicted by court-martial of a sex offense in 1999, registered under the Wetterling Act after his discharge and release. After SORNA took effect, he failed to update his address and was federally prosecuted. The Fifth Circuit reversed his conviction, and the Supreme Court granted certiorari.
Whether, under the Necessary and Proper Clause, Congress may adopt any constitutional means it deems appropriate to achieve the end it wishes to accomplish.
