When Hayes Hunt says he and his team of lawyers from Cozen O’Connor and the Pennsylvania Innocence Project “wrote the book” on representing prisoners who were unconstitutionally sentenced as juveniles to life without parole, it’s not hyperbole.

After the U.S. Supreme Court ruled in Miller v. Alabama in 2012 that automatic juvenile life sentences without parole are unconstitutional and later, in Montgomery v. Louisiana, that Miller applied retroactively, Hunt and his team found themselves in uncharted legal territory.
