Seven Years Minimum for Military Sexual Assault Causing Injury: Constitutional Court Says That’s Justified

By ,

Korea’s Constitutional Court has for the first time ruled on whether the Military Criminal Act’s mandatory minimum of seven years for sexual assault causing injury within the armed forces is constitutional — and has upheld it, finding the military context justifies harsher treatment than civilian law. Here are the key points.

Issue

Does the Military Criminal Act provision imposing a mandatory minimum sentence of seven years in prison — or life imprisonment — for sexual assault causing bodily injury within the military violate the constitutional principles of proportionality between culpability and punishment, and equality before the law?

Background

  • Under Article 92-7 of the Military Criminal Act, a military member or civilian military employee who commits sexual assault against another military member or civilian employee and causes bodily injury faces a sentence of life imprisonment or a minimum of seven years in prison. Because the minimum exceeds three years, suspended sentences are unavailable as a practical matter absent statutory grounds for reduction.
  • The equivalent provision under the general Criminal Act for sexual assault causing injury imposes life imprisonment or a minimum of five years — two years lower than the military provision.

Facts

  • Navy officer A and Army officer B were each indicted in 2021 for sexually assaulting subordinates — A targeting a non-commissioned officer under his command, and B targeting a female civilian employee — causing bodily injury in both cases.
  • Both received sentences of three years and six months in prison — the floor reached after applying statutory sentencing reductions to the seven-year minimum.
  • After their applications for a constitutional referral were rejected during their appeals, both filed constitutional complaints challenging the provision’s sentencing floor as disproportionately severe.

Constitutional Court Decision

  • The Constitutional Court ruled 7 to 2 in favor of constitutionality on July 23, 2026 — the first time the court has directly addressed this provision.
  • The majority held that the provision does not violate either proportionality or equality.

On proportionality, the court reasoned that the military is a strictly hierarchical institution where the power structure creates heightened opportunities for abuse and makes victims particularly vulnerable. Sexual assault causing injury within the military causes harm beyond the individual victim — it poses a serious threat to combat readiness and military cohesion. The mandatory minimum of seven years, viewed against the gravity of the offense and the degree of culpability involved, reflects a legislative judgment that the court found sustainable.

On equality, the court found a rational basis for the two-year gap between the military provision and the equivalent civilian provision. The special characteristics of military organization, the distinct interests being protected, and the qualitatively different nature of the offense in a military context together justify treating the military offense more severely.

The Dissent (Justices Jeong Gye-seon and Ma Eun-hyeok)

  • The two dissenting justices found the provision unconstitutional on proportionality grounds.
  • They argued that the range of factual scenarios covered by the provision is extremely broad — acts of sexual assault vary enormously in form and severity, and some cases may involve no supervisory relationship and only a minor impact on military discipline.
  • Fixing the sentencing floor at seven years, such that even after applying all available statutory reductions the minimum sentence is still three years and six months of actual imprisonment, creates a concern about inflexible, one-size-fits-all punishment that fails to account for the wide spectrum of conduct the provision encompasses.

Key Takeaways

  • The Military Criminal Act’s sentencing floor of seven years for sexual assault causing injury within the military has been confirmed constitutional by a 7-to-2 majority — the first definitive ruling on this question.
  • The military context is the operative justification: the hierarchical power structure, the vulnerability it creates for victims, and the impact on military readiness and cohesion all support treating this category of offense more seriously than the civilian equivalent.
  • Because the minimum sentence exceeds three years, suspended sentences are effectively unavailable for this offense absent statutory reduction grounds — meaning convicted officers face actual imprisonment in virtually all cases.
  • The two-vote dissent signals meaningful judicial concern about mandatory sentencing floors that leave no room to account for the wide variation in the severity of conduct covered by a single provision.

Why This Matters

This ruling settles a previously unresolved constitutional question about one of the most serious offenses in the Military Criminal Act. For military justice practitioners, it confirms that the seven-year floor will remain in place and that arguments for leniency must be pursued through statutory sentencing reduction mechanisms rather than through constitutional challenge. For policymakers and reformers, the dissent’s concerns about inflexibility in mandatory minimum sentencing — particularly across a broad and varied category of conduct — remain live issues for future legislative consideration.
