1. Indecent Act by Compulsion (Sexual Molestation) | Concept

Daeryun Law Firm explanation of the concept of indecent act by compulsion (sexual molestation)


Indecent act by compulsion (sexual molestation) is a crime in which a person molests another through the unlawful means of assault or intimidation.

Here, “molestation” refers to physical contact that generally provokes sexual shame or revulsion, and it is judged to be a sexual act that cannot be tolerated under generally accepted social norms.

The “assault or intimidation” must be sufficient to infringe upon the other party’s free right of sexual self-determination, and it need not necessarily be so severe that the other party is unable to resist.

For example, even light physical contact or the act of grabbing someone’s wrist, rather than the use of strong physical force, may amount to an indecent act by compulsion in certain situations.

According to Supreme Court precedent, with respect to indecent act by compulsion (sexual molestation), it has been held that even if direct tangible force is not exercised in the form of assault or intimidation, it is sufficient if the act instilled fear.

Accordingly, indecent act by compulsion is a sex crime that may apply in a relatively broad range of situations, centering on physical contact against the explicit will of the other party.

2. Indecent Act by Compulsion (Sexual Molestation) | Severity of Punishment

The following examines the severity of punishment for indecent act by compulsion (sexual molestation).

Indecent act by compulsion (sexual molestation) belongs to the same category of sex crimes as rape (sexual assault), but its constituent elements and the degree of the conduct differ.

For rape (sexual assault) to be established, an act of forcible sexual intercourse must exist, whereas indecent act by compulsion (sexual molestation) may be established as molestation if the victim felt sexual shame, even without direct physical contact.

If a charge of indecent act by compulsion (sexual molestation) is recognized, the offender is subject to the levels of punishment set out below.

Indecent Act by CompulsionImprisonment for not more than 10 years or a fine not exceeding 15 million won
Quasi-Indecent Act by CompulsionImprisonment for not more than 10 years or a fine not exceeding 15 million won
Special (Aggravated) Indecent Act by Compulsion (use of a deadly weapon, joint commission by two or more persons, etc.)Imprisonment for a limited term of not less than 5 years
Indecent Act by Compulsion Based on a Relative RelationshipImprisonment for a limited term of not less than 5 years

Sentencing Guidelines for Indecent Act by Compulsion

▶Mitigating Factors

- If the assault or intimidation was very slight, or the degree of molestation was minor

- If the offender turned themselves in

- If the victim has expressed a wish not to have the offender punished

- No prior record of criminal punishment

- Sincere remorse and efforts to redress the harm

- A minor degree of involvement (passive participation, participation under coercion, etc.)

▶Aggravating Factors

- Molestation carried out in a sadistic or perverse manner

- Multiple victims or repeated offenses

- A victim in a vulnerable state (disability, a child, etc.)

- Intrusion upon habitation or special (aggravated) indecent act by compulsion within a relative relationship

- Soliciting a subordinate to commit the offense

- An offense by a worker at a protective facility or by a person obligated to report child abuse

- A habitual offender

- If a relationship of personal trust (teacher-student, superior-subordinate, etc.) was exploited

3. Indecent Act by Compulsion (Sexual Molestation) | Representative Types

Daeryun Law Firm areas of assistance for indecent act by compulsion (sexual molestation)


Indecent act by compulsion (sexual molestation) arises in various ways depending on the place, situation, and target of the conduct.

The following are representative types.

▶Touching Part of the Body

-Contact with the thigh, buttocks, chest, hand, or the like against the person’s will
-Acts that force a hug or a kiss are also included

Precedent: The Supreme Court ruled that a male company representative who put a female employee in a so-called “headlock” by wrapping his arm around her head at a company dinner committed an indecent act by compulsion.

▶Contact on Public Transit or in an Elevator

-Intentionally pressing against or contacting another person’s body in a crowded space
-Whether it was “incidental contact” or “intentional molestation” is the key issue

▶Molestation Exploiting a Position at Work

-A superior, teacher, or supervisor exploiting their authority to commit molestation
-Consideration of a relationship in which it is difficult for the victim to refuse

▶Molestation at a Drinking Gathering or Company Dinner

-Mistaking physical contact while drinking for a “joke” or an “expression of familiarity”
-Whether the victim showed an unpleasant reaction is important

▶Indecent Act by Compulsion in a Digital Environment

Precedent: The court ruled that if a person threatened victims met through a smartphone chat app and received nude photographs and videos containing obscene acts, a charge of indecent act by compulsion may apply.

This means that if a perpetrator threatened a victim online and received “sexual exploitation material the victim produced themselves,” the perpetrator may be regarded as a “person who committed an indecent act by compulsion indirectly.”

4. Indecent Act by Compulsion (Sexual Molestation) | Response Methods

Response methods for the suspect and the victim in an indecent act by compulsion (sexual molestation) case

The following examines response methods from the standpoint of both the suspect and the victim in matters related to indecent act by compulsion (sexual molestation).

Response Methods From the Suspect’s Standpoint

1. The Importance of the Initial Response

As soon as a person receives notice of a police investigation or of a filed complaint, organizing the facts is more important than responding emotionally.

Self-serving explanations may instead operate as unfavorable statements.


2. Deciding Whether to Admit the Charge

If a person has been wrongly accused, proving the absence of any charge takes priority over a settlement.

Conversely, if some fault is acknowledged, the punishment may be minimized through sincere remorse and efforts toward a settlement.


3. Gathering Evidence

A person should secure as much as possible to support the circumstances at the time, such as CCTV footage, text messages, call recordings, and witness statements.

Materials that include the usual relationship with the victim and conversations before and after the conduct are very important to the assessment of credibility.


4. Managing One’s Demeanor When Giving Statements

In an indecent act by compulsion case, the credibility of the victim’s statements and the suspect’s demeanor are central.

It is important to avoid expressions that may give rise to misunderstanding and to respond calmly during the investigation.

Response Methods From the Victim’s Standpoint

1. Action Immediately After the Harm

-Immediately report to 112 or visit a nearby police substation or police station
-Preserve the scene: keep clothing, the physical condition, and the surrounding environment as they are immediately after the harm
-Secure evidence: identify the location of CCTV cameras, capture text messages and SNS messages, and obtain the contact details of people nearby


2. Preparing Statements

-Statements should be very specific and consistent, and should be written with a focus on facts rather than expressions of emotion
-Before memory fades, it is advantageous to note down the gist of one’s statement


3. Using Hospitals and Sexual Violence Counseling Institutions

-Records from obstetrics and gynecology or psychiatry are key materials for proving the harm
-Connect with a sexual violence counseling center or a Sunflower Center under the Ministry of Gender Equality and Family


4. Considering Parallel Criminal and Civil Proceedings

-In addition to a criminal complaint, a person may pursue actual redress of the harm by also conducting civil proceedings, such as a claim for consolation money

5. Indecent Act by Compulsion (Sexual Molestation) | Practical Defense Points

The following examines the practical defense points for indecent act by compulsion (sexual molestation).

Key Defense Points From the Suspect’s Standpoint

In an indecent act by compulsion case, a defense strategy is established with the aim of an acquittal or a reduced sentence on the following key issues.

1. Disputing Whether the Conduct Itself Constitutes “Molestation”

The point emphasized is that the conduct the suspect engaged in does not amount to “molestation” that provokes sexual shame under generally accepted social norms.

For example, where it is proven that the conduct was merely incidental contact or a friendly gesture arising in an everyday relationship (for instance, a pat on the shoulder by way of encouragement), an acquittal may be possible.

The victim’s reaction, the circumstances at the time, third-party statements, and CCTV footage are used as decisive materials.


2. Arguing That There Was No “Assault or Intimidation”

If there was no physical force in the conduct, or the situation was one in which the victim could react freely, then compulsion is not recognized, and an element required for the crime to be established is lacking.

The key question is whether simply touching an arm or having a hand make contact rose to a level that can be regarded as indecent act by compulsion under the criminal law.


3. Rebutting the Credibility of the Victim’s Statements

If the victim’s statements contradict the chronological order, the content, or the surrounding circumstances, or lack specificity, the possibility of false statements may be raised.

In particular, where a flow of statements that is difficult to accept based on common experience is found, an assertive defense is possible on that basis.

Text and KakaoTalk messages occurring before and after the victim’s statements, and whether the statements were retracted, are key materials.


4. Arguing That, Based on Subsequent Circumstances, There Was No “Serious Harm”

If there are circumstances showing that the victim naturally conversed with the suspect immediately after the conduct or had a further meeting, this may be regarded as indicating that the victim did not strongly perceive the harm.

If the timing of the complaint was excessively late (weeks to months later), the genuineness of the alleged harm may be disputed.

For instance, the possibility of an emotional response after a breakup or a complaint arising from a misunderstanding may be presented.

Key Points of Argument From the Victim’s Standpoint

From the victim’s standpoint, building the structure of the argument around how the conduct provoked sexual shame, the clarity of one’s own refusal, and one’s state of shock at the time is a practical response strategy.


1. Emphasizing the Assessment of “Molestation” Under Generally Accepted Social Norms

From one’s own standpoint, a person must specifically state that the conduct was entirely unwanted and that the sexual displeasure was very strong.

Even simple physical contact may amount to indecent act by compulsion depending on the situation and relationship, the part of the body touched and the manner of contact, and the victim’s reaction.

It is important to give concrete form to the emotions and reactions, such as “it was sudden and unwanted physical contact” and “I felt unpleasant and frightened at the time.”


2. Highlighting That There Was a Clear Expression of “Refusal”

Whether the conduct continued despite a refusal being expressed verbally or non-verbally (pulling away, removing a hand, etc.) has a significant effect on the sentence as well.

If there are circumstances showing that displeasure was conveyed to the other party in text messages, SNS messages, or the like, these must be submitted.


3. Emphasizing the Genuineness of the Harm Based on the Circumstances

Securing hospital treatment records or statements from people nearby regarding the emotional shock immediately after the incident (insomnia, depression, panic, etc.) increases credibility.

If the conduct before or after the complaint is consistent with that of an ordinary victim, the court will assess this as a basis for credibility.


4. The Need to Explain Conversations and Conduct With the Suspect After the Incident

If there are circumstances showing that the victim later contacted the suspect or had everyday conversations, the court may use this as a basis for doubting the victim’s psychological state.

For this reason, the victim should explain in advance, in their statement, the background in which refusal was difficult because of the relationship, such as the other party being a workplace superior or a teacher, or the context in which they responded out of fear or an intent to smooth things over.
