TOPEKA, Kan. (AP) — The Kansas Supreme Court has ruled that lifetime parole for a juvenile convicted of aggravated indecent liberties with a child violates the Constitution.

In an opinion issued Friday, the high court reversed an appeals court ruling, saying the lower court was wrong to uphold lifetime post-release supervision for a man who pleaded guilty to a 2009 sexual assault on a 13-year-old he committed when he was 17.

The high court says the lifetime supervision in the case “categorically constitutes cruel and unusual punishment.” The court has previously held that lifetime parole isn’t too severe a punishment for adult sex offenders.

The Topeka Capital-Journal reports that the court sent the case back to Sedgwick County for post-release supervision sentencing.
