Legal Grounds for Dismissing Sexual Assault Charges under § 170 Abs. 2 StPO

The legal landscape surrounding sexual consent in Germany has undergone a significant evolution, particularly concerning the practice of “stealthing”—the non-consensual removal of a condom during sexual intercourse. Whereas high-profile rulings have established that such actions can constitute a criminal offense, the practical application of the law often results in the dismissal of cases before they ever reach a trial verdict.

In recent legal discussions, attention has turned to cases where proceedings for sexual assault were terminated under § 170 Abs. 2 StPO of the German Code of Criminal Procedure. This specific statute allows prosecutors to drop a case when the investigation does not provide sufficient grounds for a suspicion of a crime. For victims of stealthing, these dismissals often create a tension between the theoretical precedent set by higher courts and the evidentiary hurdles faced by prosecutors in individual cases.

The complexity of these cases often hinges on the distinction between a legal definition of a crime and the ability to prove that crime beyond a reasonable doubt in a specific instance. When a case is dismissed under § 170 Abs. 2 StPO, it does not necessarily mean the act was legal, but rather that the evidence gathered during the investigation was insufficient to justify a trial.

The Legal Precedent: Stealthing as Sexual Assault

The foundational legal shift occurred with a landmark decision by the Kammergericht (KG), the higher regional court in Berlin. On July 27, 2020, the court ruled that the secret removal of a condom during sexual intercourse, followed by ejaculation, constitutes a sexual assault under Section 177 of the German Criminal Code (StGB). This ruling marked the first time a German higher court explicitly categorized stealthing as a punishable offense.

The court’s reasoning centered on the concept of conditional consent. In these instances, the consent to engage in sexual activity is not absolute; It’s contingent upon the employ of a condom. When that condition is secretly violated, the court determined that the consent is effectively withdrawn or invalidated, transforming the act into a sexual assault. However, the court distinguished this from rape, noting that while it is a punishable sexual assault, it does not necessarily meet the legal threshold for rape if the initial act of intercourse was consensual.

This ruling established a critical legal baseline: the belief that “consent to sex” equals “consent to any form of sex” is legally incorrect. The specific terms of the agreement—in this case, protected sex—are central to the legality of the encounter.

Understanding § 170 Abs. 2 StPO and Case Dismissals

Despite the Kammergericht’s precedent, many stealthing cases are closed during the investigative phase. The primary mechanism for this is Section 170, Paragraph 2 of the Strafprozessordnung (StPO). This provision mandates that the public prosecutor’s office must dismiss the proceedings if the investigation does not yield “sufficient suspicion” that a criminal offense was committed.

In the context of stealthing, a dismissal under § 170 Abs. 2 StPO typically occurs for several reasons:

  • Lack of Evidence: Unlike many other crimes, stealthing often occurs without witnesses. If the accused denies the act and there is no forensic or digital evidence (such as messages admitting the act), prosecutors may find the evidence insufficient.
  • Credibility Assessments: In cases where the only evidence is the conflicting testimony of two parties, prosecutors may determine that the suspicion is not “sufficient” to ensure a conviction at trial.
  • Procedural Hurdles: If the victim’s account is deemed inconsistent or if the timeline of events is unclear, the case may be closed to avoid a likely acquittal.

that a dismissal under § 170 Abs. 2 StPO is not a judicial acquittal. An acquittal occurs after a full trial where a judge decides the defendant is not guilty. A dismissal under § 170 Abs. 2 StPO is an administrative decision by the prosecutor that the case is not strong enough to proceed to trial.

The Gap Between Law and Practice

The discrepancy between the Kammergericht’s ruling and the frequency of dismissals under § 170 Abs. 2 StPO highlights a systemic challenge in the German legal system. While the law now recognizes the violation of conditional consent as a crime, the evidentiary standards required to move a case from “investigation” to “trial” remain high.

For legal practitioners and victims, this means that the “legal” victory of the 2020 ruling does not automatically guarantee a “procedural” victory. The burden remains on the prosecution to prove not only that the condom was removed, but that it was done so intentionally and without the other party’s knowledge.

This gap often leaves victims in a precarious position. While they have been told by the legal system that their experience is a recognized crime, the practical outcome of their specific case may be a letter stating that the proceedings have been discontinued due to a lack of sufficient suspicion.

Impact on Victims and Future Legal Trends

The ongoing tension between these rulings and the actual rate of prosecutions is driving a broader conversation about sexual autonomy and the “No means No” (Nein heißt Nein) principle integrated into German law in 2016. By framing stealthing as a violation of consent, the courts are aligning sexual assault laws with a modern understanding of bodily autonomy.

Legal experts suggest that as more cases are reported and more specific evidence is gathered—such as the use of communication logs or corroborating testimony—the rate of dismissals under § 170 Abs. 2 StPO may decrease. However, until the evidentiary requirements for “sufficient suspicion” are met, the precedent set by the Berlin court remains a theoretical shield that is difficult to activate in practice.

For those seeking legal guidance, the distinction between a legal lack of grounds (meaning the act itself isn’t a crime) and a factual lack of grounds (meaning the act happened, but cannot be proven) is the most critical element of any defense or prosecution strategy in these cases.

Key Takeaways on Stealthing Law in Germany

  • Criminal Status: The Berlin Kammergericht ruled in July 2020 that stealthing is a punishable sexual assault under § 177 StGB.
  • Conditional Consent: Consent for protected sex is not consent for unprotected sex; violating this condition is a legal breach.
  • Procedural Dismissal: Many cases are dropped under § 170 Abs. 2 StPO, not because the act is legal, but because evidence is insufficient for trial.
  • Evidence Gap: The lack of third-party witnesses often makes these cases difficult to prosecute despite the existing legal precedent.

The next significant development in this area will likely come from further appellate court rulings that clarify how “sufficient suspicion” should be evaluated in cases of conditional consent. Until then, legal professionals continue to navigate the divide between the high-level precedent of the Kammergericht and the daily realities of the prosecutor’s office.
