What is the prohibition of reformatio in peius?
The prohibition of reformatio in peius is a procedural safeguard that prevents a defendant’s legal position from being worsened solely because they appealed against a judgment. The Latin expression means “a change for the worse”. In Polish criminal proceedings, this principle is intended to ensure that a person does not refrain from using an appeal merely because they fear that the appellate court may impose a more severe outcome.
In practical terms, where an appeal has been lodged only in favour of the defendant, the court hearing the appeal cannot, subject to statutory exceptions, issue a ruling that is less favourable to that defendant. This rule is particularly important in criminal cases, in which an appeal may concern a conviction, the legal classification of an offence, the penalty imposed, preventive measures, compensation obligations or other elements of the judgment.
The principle is regulated primarily in Article 434 of the Polish Code of Criminal Procedure. It is connected with the adversarial nature of appellate proceedings and the right to an effective defence. Its purpose is not to guarantee that every appeal will succeed, but to protect the appellant against negative consequences resulting exclusively from exercising the right to challenge a judgment.
How does the prohibition of reformatio in peius operate?
The direct prohibition applies before the appellate court. If neither the prosecutor nor another authorised party lodges an appeal to the defendant’s detriment, the appellate court may not, subject to statutory exceptions, worsen the defendant’s situation. For example, where only the defendant challenges a custodial sentence, the appellate court cannot increase that sentence or replace it with a more severe penalty.
The scope of the prohibition depends on the content and direction of the appeal. An appeal may be lodged in favour of the defendant or to their detriment. A prosecutor, injured party acting as an auxiliary prosecutor, or other authorised participant may, in circumstances provided by law, challenge a judgment seeking a stricter outcome. If an appeal to the defendant’s detriment has been validly filed, the appellate court may examine the case within the limits set by that appeal and applicable procedural rules.
The assessment is not limited to the length of imprisonment or the amount of a fine. A ruling may be considered less favourable when it changes the legal classification of an act to a more serious offence, imposes a more burdensome criminal measure, increases a compensation obligation, or otherwise aggravates the consequences of the judgment for the defendant.
Polish criminal procedure also recognises an indirect prohibition of reformatio in peius. Under Article 443 of the Code of Criminal Procedure, where a judgment has been quashed and the case remitted for reconsideration following an appeal lodged exclusively in favour of the defendant, the court reconsidering the case may not, subject to statutory exceptions, issue a more severe judgment than the quashed judgment. This prevents the safeguard from being circumvented through remittal of the case for retrial.
Why is this principle important in criminal proceedings?
The prohibition of reformatio in peius reduces the procedural risk associated with filing an appeal. Without it, a defendant could be discouraged from challenging errors in factual findings, legal assessment, sentencing, evidentiary rulings or procedural irregularities. The rule therefore supports the practical exercise of the right to appeal.
At the same time, the prohibition does not mean that an appeal filed by the defendant automatically leads to a more favourable result. The appellate court may dismiss the appeal and uphold the original judgment. It may also amend the judgment in a way that is not detrimental to the defendant. Whether the prohibition applies in a particular case requires an analysis of who filed appeals, what grounds were raised, and which parts of the judgment were challenged.
When is legal assistance useful?
Legal assistance may be important before filing an appeal against a criminal judgment and during appellate proceedings. The wording, scope and grounds of an appeal can affect the powers of the appellate court and the procedural position of the parties. This is especially relevant where both the defence and the prosecutor have appealed, where the judgment has been partially challenged, or where the case may be returned to the court of first instance.
A prompt consultation with a criminal defence lawyer can help identify whether an appeal may expose the defendant to a less favourable ruling, whether the prohibition of reformatio in peius applies, and how to formulate appellate arguments without overlooking procedural requirements. It may also help avoid errors that could limit the effective review of the judgment.
