US courts have seen numerous constitutional challenges to laws placing restrictions on sex offenders. In August, the American Civil Liberties filed a complaint in federal court seeking to block a Louisiana law that limits Internet use for registered sex offenders [JURIST report]. In May 2010, the US Supreme Court ruled that mentally ill sex offenders may be civilly committed [JURIST report] beyond their prison sentences. The New Jersey Supreme Court ruled [JURIST report] in May 2009 that local ordinances prohibiting convicted sex offenders from living near schools, playgrounds, and other public areas were preempted by the state's Megan's Law and, therefore, invalid. In March 2009, the US Court of Appeals for the Fourth Circuit ruled that a South Carolina law requiring convicted first degree sex offenders to submit to a DNA test and pay $250 in processing fees prior to their release does not violate the ex post facto clause of the Constitution [JURIST report]. A judge in the US District Court for the Eastern District of California ruled in February 2009 that the Sex Offender Registration and Notification Act of 2006 (SORNA), which makes it a federal crime for a sex offender to attempt to move to another state [JURIST report] while failing to register in a nationwide database, is unconstitutional.
