43. Sentence

U.S. Appeals Court    Lyons v. Mendez, 303 F.3d 285 (3rd Cir. 2002).
                      A prisoner sought habeas corpus relief and the
  EX POST FACTO       district court denied his petition. The appeals
                      court reversed and remanded, finding that the
  PAROLE-GRANTING     imposition of additional, retrospective
                      punishment on the prisoner was a violation of the
                      ex post facto clause. The U.S. Parole Commission
                      had applied a good cause provision in a parole
                      determination statute, which the appeals court
                      found to be an ex post facto violation for
                      members of a class of prisoners who committed
                      crimes between the enactment of the statute and
                      its subsequent amendment. The appeals court held
                      that the prisoner was entitled to a parole
                      release date that was within the guideline range,
                      rather than the later date that the Commission
                      set by applying the subsequent statutory
                      amendment. (U.S. District Court, Middle District
                      of Pennsylvania)
