Plea bargaining in the United States
The constitutionality of plea bargaining was established by "Brady v. United States" in 1970, although the Supreme Court warned that plea incentives which were sufficiently large or coercive as to over-rule defendants' abilities to act freely, or used in a manner giving rise to a significant number of innocent people pleading guilty, might be prohibited or lead to concerns over constitutionality. "Santobello v. New York" added that when plea bargains are broken, legal remedies exist.
Plea bargain
Poland also adopted a limited form of plea bargaining, which is applicable only to minor felonies (punishable by no more than 10 years of imprisonment). The procedure is called “voluntary submission to a penalty” and allows the court to pass an agreed sentence without reviewing the evidence, which significantly shortens the trial.
There are some specific conditions that have to be simultaneously met:
However, the court may object to the terms of proposed plea agreement (even if already agreed between the defendant, victim and prosecutor) and suggest changes (not specific but rather general). If the defendant accepts these suggestions and changes his penalty proposition, the court approves it and passes the verdict according to the plea agreement. In spite of the agreement, all the parties of the trial: prosecution, defendant and the victim as an auxiliary prosecutor (in Poland, the victim may declare that he wants to act as an "auxiliary prosecutor" and consequently gains the rights similar to official prosecutor) - have the right to appeal.
