Justice Marshall also believed that the Due Process Clause gave rise to a liberty interest in being released on parole, and rejected the majority's distinction between release and revocation. That difference was not constitutionally significant, Marshall argued, because the Court had recognized a liberty interest in future freedom in other contexts. Marshall observed that the Court's prior decisions never had held that the process due a person upon a deprivation of liberty depended on the extent to which subjective determinations were involved. Finally, parole was such an integral part of the criminal sentencing scheme that it was difficult for Marshall to imagine that there was not an abstract liberty interest in parole.
