9-30-2009 National:

Cert Granted in Carr v. United States 08-1301

Whether a person may be criminally prosecuted under 18 U.S.C. § 2250for failure to register when the defendant’s underlying offense and travel in interstate commerce both predated the Sex Offender Registration and Notification Act’s enactment ; whether the Ex Post Facto Clause precludes prosecution under § 2250(a) of a person whose underlying offense and travel in interstate commerce both predated SORNA’s enactment.

In essence the court will be looking at this long standing case:
CALDER v. BULL 8-1-1798: This is the source of all ex post facto cases: The court holding a law is a ex post facto violation if any of the following have occurred:

1st. Every law that makes an action , done before the passing of the law, and which was innocent when done, criminal; and punishes such action.

2nd. Every law that aggravates a crime, or makes it greater than it was, when committed.

3rd. Every law that changes the punishment, and inflicts a greater punishment, than the law annexed to the crime, when committed.

4th. Every law that alters the legal rules of evidence, and receives less, or different, testimony, than the law required at the time of the commission of the offence, in order to convict the offender.
