The Supreme Court ruled that mandatory life sentences without parole for juvenile offenders is unconstitutional, violating the Eighth Amendment's ban on cruel and unusual punishment. The majority found juveniles have less culpability due to their immaturity and impulsivity, and such sentences preclude consideration of mitigating factors. Pennsylvania has the most prisoners serving this sentence for juvenile crimes, including one who is now 75 years old after being incarcerated since age 15. The legislature must now reconsider how to handle these cases in light of youth characteristics and the crime. This ruling could lead Pennsylvania to generally reexamine penalties that have become excessively long over the years.
