COLUMBUS (AP) — Ohio’s Supreme Court says a 2008 law’s procedure allowing sex offenders to stop registering with authorities if they committed certain sexual offenses after the law was implemented doesn’t apply to offenders convicted under a previous law.

The court ruled 6-1 Wednesday in the case of Aaron Von, who moved to Ohio in 2011. Von cited the Adam Walsh Act that took effect in 2008 when asking a trial court to end registration requirements stemming from his conviction for sexually assaulting a child in Colorado in 1997.

Ohio’s highest court found Von is subject to requirements of the 1996 Megan’s Law that was replaced by the Adam Walsh Act in 2008. Megan’s Law didn’t provide for ending registration requirements.

Von’s attorney didn’t immediately return a call seeking comment Wednesday.
