False Accusation Lawyer | What counts as false accusation, and how intent decides the case
False accusation (mugo) punishes a person who reports or files a criminal or disciplinary complaint against someone else knowing the underlying facts to be false (형법 제156조). Being investigated for this charge does not mean you are guilty just because your original complaint was dismissed or the other party was found not guilty - the prosecution must prove you knew, at the time you reported, that what you said was false. This page explains the legal elements, why the intent issue is the battlefield in most mugo cases, and what a practical defense looks like.

False Accusation | What the prosecution must prove
A false accusation charge is not established simply because a complaint you filed did not lead to a conviction. Several distinct elements must all be met.
Reporting or accusing to a government authority
The statement must have been made to a prosecutor, police officer, or other official empowered to investigate or discipline, with the purpose of subjecting someone else to criminal punishment or a disciplinary measure (형법 제156조). A private complaint made only to a company's internal HR department, for example, may not satisfy this element in the same way a police report does.
The reported facts must be false
The core facts reported - not every peripheral detail - must be objectively untrue. Courts distinguish between a report that turns out to be false because the underlying facts genuinely differed from what happened, and a report that was merely unprovable or where the accused party was given the benefit of the doubt.
The report must be about facts, not opinion or exaggeration
Exaggerating the severity of an incident, or characterizing ambiguous conduct in the way most favorable to yourself, does not automatically amount to a false report. Courts have repeatedly held that a report is not 'false' merely because it turned out to be legally or factually weaker than the reporter believed.
False Accusation | Did you know it was false when you reported it?
In practice, this is where nearly every mugo case is won or lost. The Supreme Court requires that the reporter have actual knowledge of falsity, not mere negligence or a mistaken belief.
Actual knowledge, not negligence, is required
The Supreme Court has consistently held that false accusation requires the reporter to have positively recognized that the reported facts were false; a report based on a mistaken belief, faulty memory, or a reasonable but incorrect interpretation of events does not satisfy the intent requirement even if it later proves incorrect.
A non-prosecution decision on your original complaint is not proof of your intent
Prosecutors and defense counsel sometimes treat a dismissed complaint or a not-guilty verdict against the person you reported as strong circumstantial evidence that you lied. But the legal standard for the original complaint (proof beyond reasonable doubt of the other person's guilt) is different from - and higher than - what is needed to conclude that you subjectively knew your report was false.
Ambiguous or conflicting accounts of a shared incident
Many mugo investigations arise from he-said-she-said situations - workplace disputes, relationship conflicts, business disagreements - where both sides genuinely experienced the incident differently. If your account is a reasonable, if ultimately unaccepted, version of events, that supports an argument that you lacked the required knowledge of falsity.
False Accusation | Building a defense once you are the suspect
Once a false accusation investigation is opened against you, the strategy shifts to reconstructing what you actually believed at the time you filed the original report - not defending the truth of that report all over again.
Reconstruct your state of mind at the time of the original report
Text messages, recordings, medical records, or witness statements from around the time of the original incident can show what you reasonably believed had happened, even if it later could not be proven to the standard required for a criminal conviction.
Distinguish 'unprovable' from 'false'
A key defense theme is showing that your original complaint failed for lack of sufficient evidence, not because the facts you reported were affirmatively untrue. This distinction is often the difference between an unfounded criminal complaint and a criminal false accusation.
Retraction and self-reporting can reduce or eliminate punishment
If a person who filed a false report retracts it before a judgment becomes final in the underlying case (or before a disciplinary decision is made), the punishment for false accusation may be reduced or the person may be exempted from punishment (형법 제157조, 제153조). Whether and how to retract, however, requires careful legal judgment, since a poorly handled retraction can itself be read as an admission.
False Accusation | From receiving a summons to case resolution
Determine whether you are being investigated as a suspect and, where possible, review the complaint filed against you and any related non-prosecution decision to understand exactly what statements are being characterized as false.
Gather contemporaneous records - messages, recordings, medical or workplace documentation - that show what you believed and knew at the time you made the original report.
Because intent is the central issue, how you explain your original state of mind during questioning matters a great deal; inconsistent or defensive answers can be misread as admissions of knowledge of falsity.
Before an indictment decision is made, submitting a written statement addressing the falsity and intent elements directly can affect whether the case proceeds to summary indictment, formal indictment, or non-prosecution.
If the case proceeds to trial, the focus remains on whether the prosecution can prove beyond reasonable doubt that you knew the reported facts were false at the time you made the report.
False Accusation | How fees are typically structured
An initial fee may apply to reviewing the original complaint, any non-prosecution decision, and the evidence against you before a defense strategy is set.
Set according to the stage of the case (pre-investigation, police investigation, prosecutorial review, or trial) and the complexity of reconstructing the intent issue.
Some firms structure a portion of fees around the procedural outcome (e.g., non-prosecution, summary fine instead of trial); any such arrangement should be set out clearly in the written retainer agreement.
Costs such as document copying, expert opinions, or record requests are billed separately from the legal fee itself.

False Accusation | Self-Check Before You Respond
1️⃣ Understanding Your Situation
- Has your original complaint already ended in a non-prosecution decision or a not-guilty verdict against the person you reported?
- Have you received a summons, phone call, or written notice referring to a false accusation investigation against you?
- Do you know exactly which statement in your original report is being treated as false?
2️⃣ Reviewing Your State of Mind at the Time
- At the time you made the report, did you genuinely believe the facts you reported were true?
- Do you have any contemporaneous records (messages, medical visits, witness accounts) supporting your belief?
- Was your account based on your direct experience, or did it rely on secondhand information you were told by someone else?
3️⃣ Before Speaking to Investigators
- Have you reviewed the full non-prosecution decision or judgment to understand the specific reasoning against your original complaint?
- Are you prepared to explain, calmly and consistently, why you believed the facts at the time - rather than re-arguing the truth of the original incident?
- Have you avoided making any written statement (social media, messages to the other party) that could be read as retaliation or intimidation?
4️⃣ Considering Retraction
- Has a final judgment or disciplinary decision already been made in the underlying case?
- Would a retraction at this point genuinely reflect a change in your belief, or would it appear as a strategic admission?
- Have you discussed the risks and benefits of retraction with counsel before taking any action?
