Korea’s Three-Level Criminal Trial System and the “Presumption of Innocence” — What Does “Final Acquittal” Mean?
News about criminal cases often uses terms such as “first-instance ruling,” “appeal,” “remand after reversal,” and “final acquittal.” That is because Korea’s criminal trial system follows a three-level structure, allowing a case to be contested up to three times rather than ending after a single trial. Once you understand the terms, you can accurately read which stage a case is currently in.

First instance → second instance (appeal) → third instance (final appeal)
- First instance: a district court makes the initial judgment on the facts and legal issues.
- Second instance (appeal trial): if a party challenges the first-instance judgment, the case is heard again by a high court or another appellate court. Both facts and law may be disputed.
- Third instance (final appeal): the Supreme Court handles the case and, in principle, reviews whether the law was applied correctly as a court of law.
Meaning of “remand after reversal” and “finalized”
If the Supreme Court finds a problem with the lower court’s judgment, it sets aside the judgment and sends the case back to a lower court for a new hearing. This is a remand after reversal. Conversely, when the judgment can no longer be contested, such as when a final appeal is dismissed or an appeal is waived, the judgment becomes “final.” A “final acquittal” means that an acquittal has become final and can no longer be overturned.
Principle of presumption of innocence
The Constitution states that a criminal defendant is presumed innocent until a guilty verdict becomes final (Article 27 of the Constitution). In other words, even if a person has been indicted or found guilty at first instance, they are not legally guilty until the judgment becomes final. This is tied to a fundamental principle of criminal law: the prosecutor bears the burden of proving guilt, and when there is doubt, the case should be judged in favor of the defendant.
When reading news, check the stage first
In criminal case reporting, the current procedural stage matters more than the conclusion. The meaning changes depending on whether it is a first-instance judgment, an appeal judgment, or a Supreme Court decision. In particular, a judgment that is not yet final may change in later proceedings, so it is better not to treat a headline alone as the final conclusion.
The presumption of innocence does not mean taking the defendant’s side. It means the state must prove its case sufficiently before punishing a person. That is why, until the judgment becomes final, the defendant is not legally treated as guilty.
