The concept of plea bargain itself, originated from the American jurisprudence and became established in the case of Brady v. United States 397 U.S 742 (90 S.Ct.1463, 25 L.Ed. 2d 747). Below are the brief facts of the case: In 1959, the accused/petitioner was charged with kidnapping and faced a maximum penalty of death. He was represented by competent counsel and at fast, elected to plead guilty. Upon hearing that his co-accused had confessed to the authorities, would plead guilty and be available to testify against him, he changed his plea to guilty. His plea was accepted after he was twice questioned as to the voluntariness of the plea and he was subsequently sentenced to 50 years imprisonment. In 1967, he sought for relief under 28 U.S.C 2255 claiming that his plea of guilty was not voluntary. He claimed that his counsel mounted impermissible pressure on him to plead guilty. The district court for the District of New Mexico denied him the relief. The Court of Appeal affirmed the decision of the District Court. The Supreme Court of the United States in affirming the decision of the Court of Appeal had this to say: “The issue we deal with is inherent in the criminal law and its administration because, guilty pleas are not constitutionally forbidden because the criminal law characteristically extends to the Judge or jury a range of choice in setting the sentence in individual cases, and because both the State and the defendant often find it advantageous to preclude the possibility of the maximum penalty authorized by law. For a defendant who sees slight possibility of acquittal, the advantages of pleading guilty and limiting the probable penalty are obvious. His exposure is reduced, the correctional processes can begin immediately, and the practical burdens of a trial are eliminated. For the State, there are also advantages- the more promptly imposed punishment after an admission of guilt may more effectively attain the objectives of punishment; and with the avoidance of trial, scarce judicial and prosecutorial resources are conserved for those cases in which there is substantial issue of the defendant’s guilt or in which there is a substantial doubt that the State can sustain its burden of proof.” The Supreme Court of the United States stated further that: “Of course, that the prevalence of guilty pleas is explainable does not necessarily invalidate those pleas or the system which produces them. But we cannot hold that it is unconstitutional for the State to extend a benefit to a defendant who in turn, extends a substantial benefit to the state and who demonstrates by his plea that he is ready and willing to admit his crime and enter a correctional system in a frame of mind that affords hope for success in rehabilitation over a shorter period of time than might otherwise be necessary.” Subsequently and with this seal of approval by the US Supreme Court, the courts treated a plea bargain as contracts between the prosecutors and defendants. If the defendant breaks a plea bargain, the prosecutor is no longer bound by his or her side of the deal. If a prosecutor reneges on a plea bargain, the defendants may seek relief from the court.
