State Constitutional Law as Evidence of Evolution: How State Supreme Court Decisions Should Influence Eighth Amendment Doctrine

The Eighth Amendment to the U.S. Constitution bans “cruel and unusual” punishment. Historically, the Amendment’s protection has limited the use of the death penalty, life without parole sentences for juveniles, and other extreme punishments. The Supreme Court’s Eighth Amendment jurisprudence has been both controversial and unpredictable. Fortunately, every state constitution has an Eighth Amendment analog, and state supreme courts have independent authority to interpret those provisions as they see fit. State constitutions are therefore an alternative avenue for defining what constitutes unconstitutional punishment, and this area of law is a uniquely suitable context for state constitutional decisions to exert influence over the development of federal constitutional doctrine. While state supreme courts have typically followed the Supreme Court’s say-so on cruel and unusual punishments, recent state constitutional decisions may indicate a shifting tide toward more robust development of state constitutional law in this area. This Note argues that the Supreme Court should strongly consider such state constitutional decisions in assessing “evolving standards of decency” under the Eighth Amendment.
