We granted certiorari in order to answer the question whether the trial court should have granted Hanson’s motion to quash an indictment against him because the district attorney had granted him transactional immunity.
Hanson was arrested in DeKalb County in 1979 for possession *740 and sale of methaqualone in violation of the Controlled Substances Act. In exchange for some cooperation in furnishing information concerning drug and gambling investigations, the district attorney gave Hanson a letter in which he purported to grant immunity from prosecution for all violations of the law within his jurisdiction prior to September 8,1980. A DeKalb County judge also signed a postscript to the letter which noted that the letter had been called to the attention of the court. At about the same time the district attorney dismissed the charges pending against Hanson. The dismissal was noted on the file, the notation giving no reason for the dismissal.
After the district attorney was defeated in his bid for re-election, the new district attorney submitted the dismissed cases to the grand jury, which indicted Hanson for possession and sale of methaqualone. Hanson’s attorney filed a motion to quash the indictment, relying upon the letter from the former district attorney. There was no copy of this letter in the case file. The trial court denied the motion, and the Court of Appeals reversed, holding that the promises of the public prosecutor and the public faith pledged by him must be kept.
Hanson v. State,
In affirming it is necessary to address four issues: (1) Was Hanson entitled to either a common law transactional immunity or to the use and derivative use immunity provided by Code Ann. § 38-1715? (2) If not, did the prosecutor have the power to promise to forgo prosecution in exchange for information? (3) If the promise were valid, to what extent was it binding? (4) If the promise were valid and binding, did it bind the prosecutor’s successor in office?
1. In England and this country, for over two centuries amnesty has been extended to individual offenders or classes of offenders in exchange for incriminating information. This practice is particularly useful in the context of offenses for which “... proof and punishment were otherwise impracticable because of the implication in the offense itself of all who could bear useful testimony.” 8 Wigmore, Evidence, § 2281 (McNaughton Rev. 1961) at 492. The removal of penal consequences is referred to in this country as immunity, which “... signifies the beneficial result to the offender...” as opposed to amnesty, which “ ... signifies the sacrificial act on the part of the state” Id. at 493.
A grant of immunity may be given in many different contexts — as part of a plea bargain, in exchange for testimony or'confession, or in exchange for other evidence. Where the defendant relinquishes valuable constitutional rights in exchange for immunity, the question of enforcement of the bargain has constitutional overtones. This is true whether the rights relinquished are Sixth Amendment rights, as in the case of a plea bargain, or Fifth Amendment rights, as in the case *741 of a confession or incriminating testimony.
The immunity granted in exchange for
compelled
testimony must be sufficiently broad to protect the witness to the extent of his Fifth Amendment privilege against self-incrimination. The immunity granted may be “transactional,” which protects the person testifying against prosecution for any transaction touched on in his testimony whether or not his involvement can be independently proven. A more limited immunity, “use and derivative use” immunity, protects the witness from the use of either the incriminating testimony or the fruits of such testimony.

The first federal immunity statute, passed in 1857, provided immunity to anyone testifying before either house of Congress for any fact or act upon which he touched in his testimony. 11 Stat. 155-156 (1857). This very broad protection encouraged so-called “immunity baths.” To gain immunity, witnesses testified in droves before congressional committees as to offenses both relevant and unrelated to matters under investigation. Comment,
Immunity Grants to Suspected Criminals to Secure Testimony,
18 Loyola L. Rev. 115 (1971-72). This situation led Congress to substitute a statute which provided only use immunity and which made no provision for immunity from derivative use of the incriminating testimony. 12 Stat. 333 (1862). In Counselman v. Hitchcock,
*742
In 1975 the Georgia Legislature passed the Georgia Witness Immunity Act, Ga. L. 1975, pp. 727, 728, Code Ann. § 38-1715, which provides use immunity for a witness compelled to testify. We have held that this statute provides constitutional protection adequate to compel testimony.
Brooks v. State,
Since we have concluded that there is no common law transactional immunity in Georgia, the next question which must be considered is whether the district attorney had the authority to promise to forgo prosecution apart from the statutory authority granted in Code Ann. § 38-1715. The state argues that the statute is broad enough to encompass any agreement to excuse a person from prosecution and that the prosecutor could make no promise without following the procedure set out in the statute.

We do not agree. From
*743
the beginning of our criminal justice system prosecutors have exercised the power of prosecutorial discretion in deciding which defendants to prosecute. The prosecutor’s bargaining power is a crucial factor in the disposition of criminal charges. Santobello v. New York,
Hanson neither engaged in a plea bargain nor was he compelled to testify. He apparently gave information in exchange for dismissal of charges against him and a promise of the prosecutor not to prosecute him for any crimes committed prior to September, 1980. As far as the record shows, he gave up no constitutional right. Therefore, he was not entitled to immunity for the purpose of constitutional protection.
2. Having decided that Hanson can claim neither a common law transactional immunity nor the use and derivative use immunity extended by Code Ann. § 38-1715, we are faced with the question whether and to what extent Hanson can claim the benefit of his bargain with the district attorney. The answer to this question depends upon whether the prosecutor had authority to make an agreement with Hanson and the extent of that authority. At common law the prosecutor enjoyed absolute control over the entry of a nolle prosequi until the jury was sworn.
We find that the prosecutor, as part of the authority of his office, has the sole discretion to dismiss cases prior to indictment. The operation of his office and the fulfillment of his function in our criminal justice system demands that he have this power. As noted above, our statutes require that the prosecutor obtain court approval for the entry of a nolle prosequi. Logic would dictate that he also obtain court approval for an agreement to enter a nolle prosequi.
The questions remaining do not deal with the authority of the prosecutor to enter into an agreement to dismiss specific charges, to grant immunity in exchange for the relinquishment of valuable constitutional rights, or to enter a nolle prosequi. We must consider his authority to forgo prosecution in exchange for information or evidence which is not compelled and the necessity of his obtaining court approval before entering into such an agreement. We conclude that in the future court approval will be required.
Aside from the question whether court approval is necessary for an agreement to forgo prosecution, we must consider whether the prosecutor has the power to promise to forgo prosecution of all crimes committed by an individual in exchange for information or evidence. Such a blanket promise rises to the level of amnesty or a pardon. The power to grant pardons is traditionally a function of the executive and in Georgia is in the Pardon and Parole Board alone. Code Ann. §§ 2-2001, 2-2802. We find that while the prosecutor has, with court approval, the power to promise to forgo prosecution, this promise must be limited to prosecution as to specific crimes or transactions. Therefore, a valid promise to forgo prosecution based on prosecutorial discretion rather than on Code Ann. § 38-1715 must, first, contain a description of the crimes or transactions in regard to which an individual is excused from prosecution. Secondly, the prosecutor must obtain court approval of an agreement to forgo prosecution. We reiterate that court approval is not necessary to a mere decision to dismiss charges where there is no promise to forgo prosecution in the future.
3. Having declared the parameters of a valid promise to forgo prosecution, we conclude that the agreement involved in the case at hand was too broad to be enforceable in that it purported to insulate Hanson from prosecution for all crimes committed in the jurisdiction of the DeKalb County district attorney prior to September 8,1980, the date of the agreement. This agreement, apparently covering all crimes known or unknown, is clearly too broad. The agreement recites that the promise is given in exchange for information and *745 assistance regarding drug and gambling investigations. The trial court found that the document did not reflect valid mutual consideration. However, the record reveals nothing which disputes the recital of consideration in the agreement. Assuming, then, that Hanson kept his part of the bargain, to what extent is he entitled to the benefit of an invalid promise by the prosecutor?
Not only has this question never been decided in Georgia, the answer is in flux in other jurisdictions as well. In United States v. Ford,
The rule of U.S. v. Ford, supra, that the promise of a prosecutor, which is beyond the scope of his authority, entitles the defendant only to an equitable right to executive clemency, which is not binding on the state and may not be pled as a bar, was followed for a period of time. See, e.g., Cortes v. State,
In
Smith v. State,
Thus in this state it has been indicated, although not decided, that a prosecutor may make an agreement to forgo prosecution only with the approval of the court. Further, the language in Smith indicated that the agreement may be considered as a contract and that public policy dictates that the prosecutor have the authority to make such contracts with the court’s approval. While a slavish adherence to contract law should be avoided, we find that analysis of the present agreement as a contract between the prosecutor and Hanson is useful. The parties made a bargain. There is no evidence in the record that Hanson failed to live up to his part of the bargain. Ordinarily, therefore, he would be entitled to the benefit of his bargain. We have found that court approval is necessary to make a promise to forgo prosecution binding. Here there was no specific approval although the court has indicated that the agreement was brought to its attention. We find that inasmuch as there was *747 previously no requirement of court approval, the procedure adopted in Division 2 above is required prospectively only, and we refuse to find the instant agreement invalid for lack of approval.
The question of court approval aside, we find that the terms of this agreement are beyond the power of the prosecutor to grant, being in the nature of a blanket amnesty or pardon. Public policy demands, however, that the fact that the agreement was ultra vires should not cause it to fail entirely. We therefore hold that to the extent that a promise to forgo prosecution could be validly made to Hanson, such an agreement is deemed to have been made.
In the light of the circumstances surrounding the agreement here, including the dismissal of specific charges, we find that the agreement not to prosecute is binding as to those charges, including the subject of the indictment here. In the future, an agreement to forgo prosecution must be in writing, must specifically set forth the transactions to which the promise relates, and must be approved by the court. We find that the agreement between Hanson and the district attorney is enforceable as a bar to the present indictment.
4. The final question, whether the agreement is binding on the district attorney’s successor in office, must be answered in the affirmative. The integrity of the office of the district attorney demands that promises made by the district attorney are binding on his successor to the extent that they are valid and enforceable.
Judgment affirmed.
Notes
Part of the confusion in analysis in this area comes from the use of the term “immunity.” “ [T]he basic purpose of a grant of immunity is to permit the compulsion of testimony which otherwise would be privileged by the fifth amendment.” United States v. Weiss, 599 F2d 730, 737 (5th Cir. 1979). The confusion occurs when a grant of immunity in exchange for a valuable constitutional right is approached analytically in the same way as an exercise of prosecutorial discretion in the decision *742 not to prosecute. We therefore confine our use of the term “immunity” to the protection afforded an individual who has given up a valuable constitutional right and use the term “promise to forgo prosecution” to describe the promise resulting from an exercise of prosecutorial discretion which has no constitutional overtones.
The language of the Georgia Constitution, Art. I, Sec. I, Par. XIII, Code Ann. § 2-113, affords greater protection than the literal language of the Fifth Amendment to the United States Constitution.
Code Ann. § 38-1715 provides in part: “Whenever in the judgment of the Attorney General or any district attorney, the testimony of any person or the production of evidence of any kind by any person in any criminal proceeding before a court or grand jury is necessary to the public interest, then the Attorney General or the district attorney may request the superior court, in writing, to so order that person to testify or produce the evidence.”
Since the validity of Seal’s release was not before it, the court did not address the argument that the court had exceeded its authority in ordering release in that this authority was vested solely in the Prison Board.
