In "Morrisey v. Brewer", , the Court held that due process imposed certain standards on the decision to revoke parole. The Nebraska inmates in this case argued on the basis of "Morrisey" that due process likewise required certain standards to govern the decision to grant parole. The Court disagreed, because it saw a material difference between the decision to take away freedom already granted and the decision to free someone before their legitimate expectation of release ripens. "The parole release decision is more subtle and depends on an amalgam of elements, some of which are factual but many of which are purely subjective appraisals by the Board members based on their experience with the difficult and sensitive task of evaluating the advisability of parole release". Because the decision to grant parole depends on such subjective factors, and ultimately derives from the mere hope that the Board will grant parole, the Court held that there was no "per se" liberty interest in being granted parole.
