Carr v. United States, No. 08-1301; U.S. Supreme Court; opinion by Sotomayor, J.; partial concurrence by Scalia, J.; dissent by Alito, J.; decided June 1, 2010. On certiorari to the U.S. Court of Appeals for the Seventh Circuit.
Enacted in 2006, the Sex Offender Registration and Notification Act (SORNA) makes it a federal crime for, inter alia, any person (1) who “is required to register under [SORNA],” and (2) who “travels in interstate or foreign commerce,” to (3) “knowingly fai[l] to register or update a registration,” 18 U.S.C. § 2250(a). Before SORNA’s enactment, petitioner Carr, a registered sex offender in Alabama, relocated to Indiana without complying with the latter state’s registration requirements. Carr was indicted under § 2250 post-SORNA.
