Abstract
This article examines the landmark decision in Commonwealth v. Mattis by the Massachusetts Supreme Judicial Court, which prohibits life without parole (LWOP) sentences for individuals aged 18 to 20, categorizing them as “emerging adults.” The ruling marks a significant shift in juvenile justice by extending constitutional protections against cruel and unusual punishment to young adults, based on contemporary neuroscience research indicating that brain development continues into the mid-twenties. The article discusses the implications of this decision for both the legal system and the approximately 200 individuals currently serving LWOP sentences in Massachusetts. By analyzing the majority and dissenting opinions, the article highlights the ongoing debate about the role of neuroscience in legal determinations and the potential for this decision to influence similar cases nationwide.
