Oral Arguments in Kebodeaux, the Sex Offender Registration Case

The Supreme Court heard oral arguments this week in United States v. Kebodeaux, the case testing whether Congress can require a federal sex offender to register, when the offender served out his full sentence before Congress enacted the Sex Offender Registration Act.  

The arguments centered on just how far congressional authority extends under Congress's power to regulate the military (because Kebodeaux was convicted under the UCMJ) and the Necessary and Proper Clause (because he was required to register under SORNA only after he served out his full sentence).  That latter point, the key here, in turn largely centered on the reach and understanding of United States v. Comstock, the OT 2009 case holding that Congress could authorize a federal judge to order the civil commitment of a "sexually dangerous" person in federal custody even beyond the term of his sentence.

Comstock was a 7-2 ruling, with Chief Justice Roberts joining Justice Breyer's majority opinion.  Justices Kennedy and Alito concurred separately.  Justices Scalia and Thomas dissented.  

Chief Justice Roberts sent strong signals during arguments in Kebodeaux that he sees this application of SORNA as beyond the pale.  Justices Kennedy and Alito were also critical of the government's position, but seemed slightly less firm in their positions, slightly more open.  Justice Sotomayor, too, pressed for limits on government authority.  If three of these switch from their positions in Comstock, Kebodeaux will go the other way.
