A Federal prisoner serving a maximum term or terms of more than 1 year may be released on parole at the discretion of the Commission after completion of one-third of such term or terms, or after completion of 10 years of a life sentence or of a sentence of over 30 years. Procedures for initial hearing require the discussion with the prisoner of his offense severity rating and salient factors that may be relevant to his petition. The granting of parole to a eligible prisoner rests in the discretion of the United States Parole Commission. As prerequisites to a grant of parole, the Commission must determine that the prisoner has substantially observed the rules of the institution to which he has been confined. Upon consideration of the nature and circumstances of the offense and the prisoner's history and characteristics, the Commission must determine that release would not depreciate the seriousness of his offense or promote disrespect for the law. In addition, the factors relating to whether release would jeopardize public welfare must be considered. Guidelines are presented for individual types of crime, and special procedures for special cases are included. Revisions to the procedures are attached.
