How is the upper limit of punishment for juvenile offenders set in the Sacheon high school murder case
On December 25, 2024, at the entrance of an apartment in Sacheon, Gyeongnam, a 17-year-old female high school student was stabbed to death by an 18-year-old male. Approximately 20 stab wounds were found on the victim, concentrated around the neck and abdomen. The perpetrator was reported to have continued stabbing even after confirming that the victim was dead. This article organizes the structure of the upper limit on juvenile offender punishment, the legislative intent behind it, and the flow of revision discussions that this case has brought back into focus.
Case overview and public reaction
The perpetrator and the victim were reported to have met for the first time on the day of the incident. Despite being a brutal and clearly premeditated violent crime, the fact that the death penalty or life imprisonment could not be imposed because the perpetrator had committed the crime at age 17 was emphasized, prompting strong anger among the bereaved family and citizens.
The bereaved family, along with the agony of asking why this happened to our child, urged the revision of the Juvenile Act, demanding that minors who commit premeditated and brutal crimes be punished by the same standards as adults.
Why is the death penalty or life imprisonment completely impossible for 17-year-olds
The Juvenile Act and the Act on Special Cases concerning the Punishment of Specific Violent Crimes generally prohibit the imposition of the death penalty or life imprisonment on juveniles under the age of 18. Even in cases that would warrant life imprisonment, the punishment is typically converted to a definite term of imprisonment of up to 15 years, and even in cases falling under specific violent crimes, the upper limit of punishment is generally 20 years.
- Death penalty: Cannot be imposed on those under 18
- Life imprisonment: Cannot be imposed on those under 18
- Murder qualifying as a specific violent crime: For those under 18, generally up to 20 years of definite imprisonment
If the same case had been committed by an adult, life imprisonment or the death penalty would have been on the table, so the gap in the upper limit of punishment is very large.
Legislative intent, the premise of rehabilitative potential
The upper limit of punishment under the current Juvenile Act is generally based on the following two premises.
- Rehabilitative potential of juveniles in the formative years: The criminal-policy judgment that protection and rehabilitation is more beneficial to society as a whole than criminal punishment
- Consistency with international human rights standards: Strong restrictions on the death penalty and life imprisonment for minors under international standards including the UN Convention on the Rights of the Child
However, in cases where premeditation and brutality stand out, as in the Sacheon case, this premise generally diverges greatly from the legal sentiment of members of society, and revision discussions are repeatedly highlighted.
Issues frequently raised in Juvenile Act revision discussions
- Lowering the age: Discussion of lowering the age of criminal minority (currently 14) to 13
- Raising the upper limit: Discussion of raising the upper limit of punishment for specific violent crimes (currently 20 years) to 25 or 30 years
- Differentiation by case type: Discussion of excluding the application of the upper limit for premeditated and brutal crimes
- Strengthening victim protection procedures: The right of bereaved families to state opinions, identity protection, priority procedures for damages
From the perspective of a former chief judge turned attorney
I handled many juvenile cases as a chief judge and have continued to specialize in juvenile cases since transitioning to private practice. Courts generally evaluate the sentencing of juvenile offenders based on both rehabilitative potential and victim recovery. However, in cases like the Sacheon case where the victim cannot be restored, it is difficult to deny that explaining the upper limit of sentencing based on rehabilitative potential alone is losing social persuasive power.
What both the perpetrator side and the victim side should generally know
- Bereaved family of the victim: In criminal proceedings, you can generally review with an attorney the application to state opinions, the application for a damages order, and the use of the Crime Victim Protection Fund
- Perpetrator side: At the sentencing stage, genuine remorse, efforts at restitution, and the establishment of an environment to prevent recidivism are generally key evaluation factors
Frequently asked questions
Q. Is there a significant difference in punishment between cases committed just before and just after the 18th birthday?
A. The difference is generally very large. This is because the actual age at the time of the offense is the key standard. If committed just before the 18th birthday, the death penalty or life imprisonment cannot be imposed, but if committed just after, life imprisonment or even the death penalty is possible depending on the case. The structure where the upper limit of sentencing differs by a matter of days is the core example of the legislative blind spot debate.
Q. Where does the discussion on Juvenile Act revision stand now?
A. Generally, whenever serious cases occur, discussions on lowering the age and raising the upper limit have been highlighted and then subsided repeatedly. Several amendment bills have been proposed between 2024 and 2026, but the timing of passage may vary by case, so the accumulation of social consensus is the key variable.

Closing
The Sacheon case shows most acutely the tension between the rehabilitative potential of juveniles and the irrecoverability of victim damage. To accurately understand and respond to the procedure and sentencing structure of juvenile cases, I recommend consulting an attorney well-versed in juvenile cases, such as a former chief judge, as early in the case as possible.
