In a key win for individuals nationwide who are serving life without parole sentences for crimes committed as children, the United States Supreme Court today ruled 6-3 in Montgomery v. Louisiana that their 2012 decision in Miller v. Alabama, barring mandatory life without parole sentences for youth, applies retroactively. Today’s decision guarantees that 69-year-old Henry Montgomery, along with as many as 2,000 others serving similar mandatory life without parole sentences, will receive new sentencing hearings or be considered for parole.
