Crime of Disclosure of Official Secrets
The crime of disclosure of official secrets applies when a public official, or a person who was a public official, discloses a secret learned in the course of their duties. Because the crime of disclosure of official secrets may result in the loss of one's public office, caution is necessary.
1. Crime of Disclosure of Official Secrets | Elements of the Offense

The crime of disclosure of official secrets is a crime in which a public official, or a person who was a public official, discloses a secret learned through their duties.
The subject of this crime is a public official or a person who was a public official, and it applies when that person discloses a secret of their official duties as provided by statute.
Here, disclosure means informing a third party who does not know the secret, and informing a person who already knows the secret does not constitute disclosure.
For this crime to apply, the disclosed information must be a secret of one's official duties as provided by statute.

The crime of disclosure of official secrets is also viewed not as protecting the secret itself, but as protecting the interest endangered by a breach of the public official's duty of confidentiality, that is, the function of the State that is threatened by disclosure of the secret.
In the Supreme Court's view, for this crime to apply, the disclosed secret must be one that impedes the functions of the State.
Recent Status of Bookings and Arrests
Over the past 3 years, the number of cases in which current or former public officials, including police officers, were booked for leaking official secrets has reportedly exceeded 100.
According to the National Police Agency, from 2022 through the first half of 2024, the number of cases placed under investigation on charges of disclosure of official secrets reached a total of 137.
Differences from the Crime of Violation of Secrecy
The crime of disclosure of official secrets and the crime of violation of secrecy both protect a ‘secret,’ but they differ in their subject and object, their conduct, and the legal interest protected.
The crime of disclosure of official secrets applies when a public official or a former public official discloses a secret learned through their duties.
By contrast, the crime of violation of secrecy punishes opening a sealed letter or document of another, or ascertaining its contents by technical means.
2. Crime of Disclosure of Official Secrets | Penalty Level

If the crime of disclosure of official secrets is recognized, the following punishment applies under the Criminal Act.
| Article 127 of the Criminal Act | Imprisonment with or without labor for not more than 2 years or suspension of qualifications for not more than 5 years |
Administrative Disposition
If a charge of the crime of disclosure of official secrets is recognized, you may face not only criminal punishment but also an administrative disposition that results in the loss of your public office.
Disciplinary actions include removal, dismissal, demotion, suspension from duty, salary reduction, and reprimand, and the level of discipline is determined by considering the content and intentionality of the disclosure together with one's standing as a public official.

3. Crime of Disclosure of Official Secrets | How to Respond

The crime of disclosure of official secrets is a very serious crime, and if the charge is recognized, imprisonment and a disciplinary disposition are difficult to avoid.
For this reason, it is advisable to preserve the course of events and the evidence and to establish a defense strategy promptly.
Facing an Investigation?
Before being investigated on a charge of the crime of disclosure of official secrets, it is very important to accurately grasp and organize the circumstances surrounding the case
Because statements made before the investigative authorities greatly affect not only future criminal punishment but also disciplinary proceedings, you must set the direction of your response carefully.
▷ Clarify the facts by securing relevant materials and evidence
▷ Establish a statement strategy for questioning in advance together with an attorney
▷ Refrain from unnecessary statements during the investigation and respond prudently
Want to Reduce the Penalty?
Because the crime of disclosure of official secrets does not provide for a fine by law, if the charge is recognized, there is a high likelihood of imprisonment.
The absence of intent or the fact that the harm was not significant, along with remorse and efforts to repair the harm after the incident, can be important factors in mitigating the punishment.
▷ Take active measures to minimize the harm after the incident
▷ Express an attitude of remorse and make concrete efforts to prevent recurrence
Want to Object to an Administrative Disposition?
If, after receiving an administrative disposition for the crime of disclosure of official secrets, you conclude that the disposition is unjust, you can respond actively through legal procedures such as an objection or an administrative appeal.
▷ Promptly carry out the procedure within the objection period
▷ Review additional legal remedies, such as an administrative appeal and administrative litigation
