Mabry v. Johnson
United States Supreme Court
467 U.S. 504 (1984)
While serving concurrent sentences, Johnson (defendant) accepted a prosecutor's offer of a 21-year concurrent sentence for pleading guilty as an accessory to felony murder, but the prosecutor later withdrew that offer as a mistake and instead offered a 21-year consecutive sentence, which Johnson rejected before the case went to a mistrial; Johnson then accepted the second offer and received the 21-year consecutive sentence. Johnson's habeas petition was denied by the district court but granted by the appellate court, which held fairness barred withdrawing an accepted plea-bargain offer, and the Supreme Court granted certiorari.
Whether a defendant may attack the validity of his guilty plea because a prosecutor withdrew an offer made during plea bargaining after the defendant had already accepted the offer.
