In Miller v. Alabama, the U.S. Supreme Court ruled that the distinctive attributes of youth rendered mandatory life without parole sentences for people under 18 years old unconstitutional. With its ruling in Diatchenko v. District Attorney in 2013, the Massachusetts Supreme Court went a step further, finding that discretionary life without parole sentences for youth under 18 violate the Massachusetts Constitution’s ban on cruel or unusual punishment.

In Commonwealth v. Sheldon Mattis, the Massachusetts Supreme Court will consider whether the Massachusetts Constitution categorically bars mandatory life without parole sentences for individuals aged 18 to 20 convicted of first-degree murder. The science is clear: the unique attributes of youth do not end when an individual turns 18. Young adults are also deserving of special sentencing consideration.
