LANSING, Mich. (AP) - The Michigan Supreme Court will decide whether hundreds of inmates can benefit from a U.S. Supreme Court decision that bars mandatory no-parole sentences for crimes committed under 18. The state Supreme Court will decide whether the ruling can be applied retroactively and possibly give roughly 360 inmates a shot at freedom. In 2012, the state appeals court said there should be no benefit to prisoners who long ago exhausted appeals. In an order released Thursday, the Supreme Court says it will hear arguments in three cases involving juvenile lifers from Berrien, Wayne and St. Clair counties. An Ann Arbor federal judge has said Michigan's juvenile lifers are entitled to parole hearings but nothing has happened. The attorney general's office is vowing to appeal.
