South Korea Supreme Court Reviews Decades-Old Force Threshold in Rape Cases

A rape appeal puts the meaning of force before the full court

South Korea's Supreme Court will examine whether to change a legal standard dating to February 1979 that requires violence or intimidation in a rape case to make resistance impossible or substantially difficult. The case has been referred to the court's full bench, with its first deliberation scheduled for the 22nd. The month and a date for a final decision were not specified.

The defendant, identified only as A, was convicted at trial but acquitted on appeal. The appeals court found insufficient grounds to conclude that A had acted with the intent to commit rape and used violence or threats severe enough to meet that threshold. Prosecutors appealed, bringing the case to the Supreme Court in February of the previous year.

The central issue is how much force or intimidation prosecutors must establish for a rape conviction. For 47 years, the court has retained the basic requirement that the conduct must make the victim's resistance impossible or substantially difficult, while directing judges to consider the surrounding circumstances.

A change could affect how courts assess sexual encounters involving unwanted force or threats that fall below that demanding threshold. It would also bring the interpretation of rape closer to a change the Supreme Court made in September 2023 for the separate offense of indecent assault by force or intimidation.

The review comes amid a longstanding campaign to make lack of consent the central element of rape law. Parliament has not passed those proposals, leaving the Supreme Court to consider the meaning of the violence and intimidation requirement in the existing law.

What the law requires prosecutors to show

Article 297 of South Korea's Criminal Act defines rape through sexual intercourse accomplished by violence or intimidation. It provides for imprisonment for a fixed term of at least three years.

Sungkyunkwan University School of Law's Public Interest Law Clinic set out that wording in its 2020 questionnaire response, submitted on August 20 to the United Nations special rapporteur on violence against women. The clinic answered that the definition rested on force or threats, rather than lack of consent.

The statute and the court's interpretation perform different jobs. Article 297 names violence and intimidation as elements of the offense. Supreme Court precedent tells judges how serious that violence or intimidation must be.

Under the established interpretation, judges assess whether the force or threats made resistance impossible or substantially difficult. They must consider the nature and degree of the conduct, how it arose, the relationship between the people involved, and circumstances during and after intercourse.

Prosecutors therefore face both a legal threshold and an evidence requirement. They must show that the alleged conduct meets the definition of rape and prove the charge beyond reasonable doubt. In plain language, the evidence must leave judges convinced of guilt without a reasonable doubt about the essential facts.

Earlier rulings show how the threshold operates

The Supreme Court's April 2001 ruling, case 2001Do230, illustrates how the resistance standard has shaped appeals. On April 27, 2001, the court overturned a conviction for rape resulting in injury and returned the case to the Seoul High Court for further examination.

The justices repeated that violence or intimidation must make resistance impossible or substantially difficult. They also found weaknesses in the examination of evidence, including the complainant's statements, other witness accounts and medical evidence. The lower court needed to examine the circumstances more closely before deciding whether the charge was established.

Almost a decade later, the Supreme Court's November 2010 ruling, case 2010Do9633, again applied the same standard. The court held that prosecutors had not proved rape allegations concerning October 28 and 29, 2009, beyond reasonable doubt, and sent the case back to the Seoul High Court.

The 2010 judgment addressed both the reliability of the evidence and the severity of the alleged violence or threats. It questioned whether the conduct reached the required level after considering the parties' relationship and the circumstances surrounding intercourse. The judgment also upheld the lower court's findings on separate assault and intimidation charges.

Why the 2023 decision matters

The Supreme Court has already changed a similar standard for indecent assault by force or intimidation. In September 2023, its full bench revised an interpretation that had stood for about 40 years.

For that offense, the court held that violence could consist of unlawfully applying physical force to another person's body. Intimidation could consist of communicating a threat of harm capable of causing fear. The revised standard no longer required force or threats severe enough to make resistance substantially difficult.

The current rape appeal puts a related question before the full bench: whether the court should continue requiring that high level of force or intimidation for rape while applying a broader interpretation to indecent assault.

The practical stakes concern which conduct courts can recognize as meeting the violence or intimidation element. If the Supreme Court lowers the threshold, judges would assess rape allegations under a wider understanding of those terms. Prosecutors would still have to prove every element required by the resulting legal test.

Chae Da-eun, a lawyer specializing in sexual offense cases, said the existing provisions and interpretation had faced criticism for assuming violence or threats so severe that resistance was effectively impossible. She also said some lower courts had interpreted violence and intimidation more broadly than the established precedent.

Chae viewed the full bench review as an opportunity to settle those interpretive differences and respond to the international movement toward giving greater weight to consent. That is her assessment of the court's possible direction; the justices have yet to announce their decision.

How the legal debate developed

The dispute has grown through decades of judgments, advocacy and proposals for legislation. Several dates explain how the present review fits into that history:

• February 1979: The Supreme Court first stated that violence or intimidation in rape must make resistance substantially difficult.
• April 27, 2001: Case 2001Do230 repeated the standard and required closer examination of the evidence before a conviction could stand.
• November 11, 2010: Case 2010Do9633 reaffirmed the threshold and the prosecution's duty to prove guilt beyond reasonable doubt.
• July 2018: Public debate highlighted the resistance requirement alongside the pressure some complainants faced from retaliatory legal complaints.
• August 20, 2020: Sungkyunkwan University's Public Interest Law Clinic submitted its account of South Korean rape law and barriers to reporting to a UN special rapporteur.
• September 2023: The Supreme Court lowered the force and intimidation threshold for indecent assault.
• The current appeal: The full bench is scheduled to begin considering whether to revise the rape standard on the 22nd.

The sequence shows two routes to changing the law in practice. Parliament can rewrite the offense, while the Supreme Court can change how judges interpret its existing words. The pending case concerns the second route.

Why consent remains central to the campaign

Women's organizations have repeatedly called for rape to be defined around the absence of consent. UN human rights bodies have also urged South Korea to revise its definition in that direction.

A law centered on consent asks whether a person freely agreed to the sexual activity. South Korea's existing approach places violence or intimidation at the center of Article 297, with court precedent determining the required severity.

The distinction matters when a person does not agree to intercourse but the force or threats are difficult to show at the level demanded by the current interpretation. Campaigners want the legal definition to focus directly on agreement rather than on how difficult resistance became.

The Public Interest Law Clinic's 2020 submission identified this issue as a barrier to reporting and prosecution. It also described assumptions that sexual violence is less serious when a woman has previous sexual experience, has been in a relationship with the perpetrator, or previously agreed to sex with that person. According to the clinic, such assumptions could sometimes contribute to reduced sentences.

England, Germany, France, Canada and some US states have moved toward legal approaches that give consent a central role, although their statutory tests vary. South Korean lawmakers have introduced related bills several times, but the proposals failed to pass before the relevant parliamentary terms ended.

The Supreme Court can reconsider the force threshold under Article 297. Replacing that provision with an offense expressly organized around lack of consent would require parliamentary action.

The pressure surrounding a rape complaint

Legal debates over the resistance threshold sit alongside another problem documented in 2018: complainants facing criminal complaints themselves after reporting sexual violence or speaking publicly about it.

A Seoul office worker identified as D described repeated complaints accusing her of offenses including defamation, perjury and intimidation. The man she accused was eventually convicted of rape and sentenced to two years in prison, while the accusations against her were dismissed. He continued pursuing her after leaving prison, until a 2014 conviction for stalking and intimidation ended the ordeal described in her account.

Seo Hye-Jin of the Korean Women Lawyers Association described the effect on women considering whether to pursue a complaint:

The whole system has a chilling effect on women,

South Korea's criminal defamation rules can expose someone to a complaint over public allegations even when the statements are true, depending on the legal circumstances. Reporting an allegation to police and publishing it publicly carry different legal risks. False accusation proceedings can create another source of pressure during a sexual violence case.

In July 2018, the Justice Ministry instructed prosecutors to wait until the underlying sexual abuse case had been resolved before investigating the complainant for false accusation. That measure addressed the timing of investigations, while the campaign to change rape law addressed the definition of the offense itself.

What the historical figures reveal

Korea Women's Hotline said in 2018 that only about 10 percent of rape complaints it received qualified as rape under the law at that time. The figure concerned complaints received by the organization, whose contact with survivors gave it a direct view of the gap between reported experiences and the legal threshold.

Figures attributed to the Institute of Justice showed that prosecutors dropped 55 percent of sex crime cases in 2016, compared with 22 percent of homicide cases and 26 percent of burglary and robbery cases. The sex crime figure was 33 percentage points above homicide and 29 points above burglary and robbery.

Those figures describe the prosecution environment in 2016. The current full bench review concerns one part of that environment: the legal meaning of violence and intimidation in rape cases.

For A, the immediate issue is whether the acquittal survives the prosecution's appeal. For future cases, the larger consequence would be a change in the legal test judges use to evaluate force and threats. The Supreme Court must decide whether to retain the standard, revise it, and determine how its reasoning applies to this appeal.
