Plea bargaining usually involves the defense and prosecution in a case working out a “mutually satisfactory disposition” in which the defendant pleads guilty to a lesser offense or fewer charges in exchange for a lighter penalty (Black 1991: 798). Plea bargains are not always easy to recognize. Negotiations involving formal agreements are termed “explicit plea bargains”; however, some plea bargains are called “implicit plea bargains” because they involve no guarantee of leniency. Explicit bargains are the more important of the two.
