‌Context & Objective: Acquiescence to judgment (submitting to a trial court's verdict and waiving the right to appeal in exchange for a mandatory sentence reduction) is a prevalent leniency mechanism in the Iranian criminal justice system. According to Article 442 of the Iranian Criminal Procedure Code, convicts who waive or withdraw their appeal against taʿzīr (a punishment determined at the discretion of the Islamic judge and lesser than the fixed ḥadd penalty) sentences before the judgment becomes final are entitled to mitigation, provided neither the prosecutor nor the private complainant appeals the decision. Despite the apparent simplicity of this statutory provision, its implementation reveals hidden legal complexities, as evidenced by the issuance of four precedent-setting judgments by the Supreme Court of Iran. A fundamental procedural challenge within this framework is the ambiguous role and operational conduct of the public prosecutor. Due to statutory brevity and doctrinal silence on this specific issue, prosecutorial intervention often depends on the personal preferences of judicial authorities rather than objective legal criteria. The primary purpose of this research is to define the logical boundaries of the prosecutor's right to appeal in such scenarios. Consequently, the main research question asks what the legitimate approach of the public prosecutor should be when confronting criminal convicts who submit to their initial judgments.
 ‌Method & Approach: This research employs an applied, doctrinal methodology alongside a descriptive-analytical approach to investigate the prosecutor's role in the appellate process. The study systematically interprets relevant provisions of the Iranian Criminal Procedure Code and evaluates various legal arguments, scholarly doctrines, and opposing viewpoints regarding the necessity and extent of prosecutorial appeals.
 ‌Findings: The investigation reveals three primary findings regarding the restriction of prosecutorial appeals. First, the pursuit of offenders through prosecutorial appeals against initial convictions must be measured, proportionate, and aligned with the principle of prosecutorial discretion rather than mandatory prosecution. When defendants submit to their initial convictions, the prosecutor's right to appeal should be inherently limited to serve broader strategic objectives, including the reduction of procedural stages, adherence to the principle of reasonable time in criminal proceedings, victim protection through the swift restoration of damages, the facilitation of convict rehabilitation, and the reduction of the penal population in prisons. Second, a protective, differential approach governs the leniency mechanism in the context of child and juvenile delinquency. The prosecutor is generally prohibited from appealing juvenile court judgments under the pretext of disproportionate sentencing, thereby insulating the juvenile's acquiescence to judgment from prosecutorial disruption. Third, the current legal framework necessitates substantial legislative revision concerning specific offenses. The findings emphasize that the legislature must establish an absolute prohibition on prosecutorial intervention regarding convicts' submission to judgments in forgivable crimes, taʿzīr crimes against chastity—which are subject to the Islamic criminal policy of concealment and non-investigation—and degree-seven taʿzīr offenses, where judicial leniency is inherently prioritized.
 ‌Conclusion: The legal implications of this study confirm that the overarching framework for prosecutorial appeals, in circumstances where the defendant complies with the initial trial court conviction, must be rigidly founded upon the principle of minimal intervention. While the right to a second hearing and the avoidance of judicial errors remain fundamental to fair trial standards, unchecked prosecutorial appeals undermine the efficiency and rehabilitative potential of the acquiescence mechanism. A minimalist prosecutorial approach acts as an essential procedural balance, transforming the public prosecutor from an unrestrained authority into a judicial manager who effectively harmonizes public interest with individual rights and liberties. To legally codify this minimal intervention and resolve existing judicial inconsistencies, the legislature must intervene directly. The study concludes by proposing a specific statutory amendment to Article 442 of the Criminal Procedure Code. This proposed addendum would explicitly nullify the prosecutor's right to appeal when a convict submits to the verdict in forgivable crimes, chastity offenses, degree-seven taʿzīr crimes, and all sentences issued by juvenile courts, thereby guaranteeing the procedural integrity and intended leniency of the acquiescence mechanism.
