Can You Appeal a Criminal Case in Korea? And Can the Prosecutor Appeal Too?
Written by Attorney Soobin You, a former prosecutor licensed in Korea, defending criminal cases with consultations available in English.
Quick answer: Yes, Korea has criminal appeals, and importantly, both sides can appeal. If you lose at first instance, you can appeal to try to reduce or overturn the outcome. But the prosecutor can also appeal, even when you received a favorable result, arguing the sentence was too light. This means a good first-instance outcome is not always final. Understanding both directions is essential.
For foreigners in Korea, this often comes as a shock. You receive a fine instead of prison, you feel relief, and then you learn the prosecutor has appealed to make it heavier. Here is how criminal appeals work in Korea, from a Korean English-speaking lawyer’s perspective.
Appeals go both ways
In Korea, a first-instance judgment is not necessarily the end. Either side can appeal to the next level. A defendant can appeal to seek a reduced sentence or an acquittal. But the prosecutor can also appeal, arguing that the sentence was too lenient and seeking a heavier one. This second possibility catches many people off guard: even a favorable result can be challenged.
When an appeal is filed, the case moves to an appeal court. Note that appeals are heard by designated courts, so a case from one region may have its appeal heard at a court in another. Regardless of direction, an appeal is not a simple re-hearing. It is a structured argument about what the first court got wrong, whether it overlooked mitigating factors, or weighed something too heavily.
When the prosecutor appeals a light sentence
Consider a real example. A driver with a prior drunk-driving record received a fine at first instance, a favorable result given that a repeat offense can support a prison sentence under the revised Road Traffic Act. But the prosecutor appealed, arguing the sentence was too light: that the offense was serious, that there had been a prior fine for the same conduct a few years earlier at a similar alcohol level, and that imposing the same sentence again did not reflect the purpose of the revised law.
The task on appeal was to defend the first-instance result and have the prosecutor’s appeal dismissed. This required active work: reinforcing the sentencing materials with additional written reflections and family petitions, and preparing a detailed sentencing opinion arguing that the fine was appropriate and not excessively low. The key points included that the alcohol level was not especially high, that the driver had voluntarily complied with the police check, the circumstances that led to the driving, and genuine economic hardship.
On the legal question, the prosecutor’s position was essentially that a second offense always requires a heavy sentence. Against this, an analysis of existing precedent showed that even a repeated drunk-driving offense can result in a fine where there was no accident and the risk of reoffending is low, and that the first-instance sentence could not be regarded as too light. The appeal court accepted this reasoning and dismissed the prosecutor’s appeal, so the fine stood.
Why an appeal, in either direction, needs careful handling
When the prosecutor appeals, the defendant is in a more precarious position, because a favorable result could be changed to a suspended sentence or even prison if the appeal is not actively defended. And when a defendant appeals, the scope for new steps is limited, so much of the groundwork has to be laid at first instance. In both directions, an appeal turns on reinforced sentencing materials, a persuasive sentencing opinion, and a clear legal analysis of the relevant precedents.
An appeal is argued on a record someone else assembled. Where that record was built carefully at first instance, there is something to work with; where it was not, the appeal is mostly damage control. See what defence at each stage of a Korean criminal case involves.
Frequently Asked Questions
Q: Does Korea have criminal appeals?
A: Yes. A first-instance judgment can be appealed to a higher court. An appeal is not a simple re-hearing but a structured argument about what the first court got wrong or weighed incorrectly.
Q: Can the prosecutor appeal even if I got a good result?
A: Yes. The prosecutor can appeal a sentence they consider too lenient, seeking a heavier one. This means a favorable first-instance outcome, such as a fine, can still be challenged and must be actively defended.
Q: What happens if I don’t respond to the prosecutor’s appeal?
A: You are in a more vulnerable position. Without an active defense, a favorable result like a fine could be changed to a suspended sentence or prison. Reinforcing the sentencing case on appeal is important.
Q: Can I appeal to reduce my own sentence?
A: Yes. A defendant can appeal seeking a reduced sentence or an acquittal. Because the scope for new steps narrows on appeal, doing everything possible at first instance also matters.
Q: I’m a foreigner facing an appeal in Korea. Can I get help in English?
A: Yes. A Korean English-speaking lawyer can take your account in English and handle an appeal in either direction, defending a favorable result or seeking to reduce a sentence, through reinforced materials and legal analysis.
