DES MOINES, Iowa (AP) — A U.S. Supreme Court decision that makes retroactive a 2012 ruling striking down automatic life prison terms for people sentenced as teenagers is not expected to have much impact in Iowa since the state’s Supreme Court already extended the federal court ruling.

The federal court justices on Monday voted 6-3 to extend the 2012 decision to previous cases involving teenage killers. Now, even those who were convicted long ago must be considered for parole or given a new sentence.

Iowa’s high court in the 2013 appeal of Jeffrey Ragland had already concluded the federal court’s 2012 ruling applies retroactively to teenagers previously sentenced to life. The Iowa Attorney General’s office says the ruling affected 39 Iowa juvenile life offenders and most of them have already been resentenced.
