LINCOLN, Neb. (AP) — The Nebraska Supreme Court has rejected appeals by two sex offenders who say changes by the Legislature to the Sex Offender Registration Act in 2009 violate their constitutional rights.

The law was challenged by Timothy Gaskill, convicted in 1995, and Jason Harris, convicted in 2001.

The law requires sex offenders to register current addresses and requires their names to be published on a website.

It was passed after both were convicted but Gaskill was on probation which makes him subject to it. Harris must register as a sex offender until 2013.

Both say the law imposes retroactive and additional punishment.

The court rejected the arguments saying the law punishes those who fail to register and posting the names is not additional punishment.
