Background

The Dresden Higher Regional Court was trying several defendants accused of membership in or support for a militant far-left criminal organization. Prosecutors alleged that the group used severe violence against people it associated with neo-Nazi and far-right circles, or facilitated such attacks, to combat right-wing extremist activity and ideology.

Witness E. had previously been convicted for participating in that organization and in several attacks, as well as related offenses, and received an aggregate prison sentence of five years and three months. Called to testify about the conduct underlying her final convictions, she refused to answer any substantive questions, asserting a comprehensive right against self-incrimination under Section 55(1) of the German Code of Criminal Procedure. The trial court rejected that blanket claim, imposed costs and a regulatory fine, and ordered six months’ coercive detention under Section 70(2). E. appealed after being taken into custody.

The Court’s Holding

The Federal Court of Justice dismissed the appeal and upheld the detention order. Because E.’s convictions for the events at issue were final, the prohibition against renewed prosecution generally eliminated any self-incrimination risk concerning those same procedural acts. A comprehensive refusal could be justified only by concrete facts showing that truthful testimony would expose her to prosecution for other offenses. Speculation that her answers might become a “piece in a mosaic-like structure of evidence” was insufficient, particularly because investigators already possessed detailed information about the organization and her role, prior investigations into other suspected conduct had largely been closed, and no further organization-related criminal case against her was pending. She remained entitled to refuse particular answers if an individual question created a genuine risk of prosecution.

The Court also held that Section 70(4)’s prohibition on repeating coercive detention did not bar the new order, even though another court had previously ordered six months’ detention for her refusal to testify about one of the same attacks. The earlier order had not been executed. Section 70(4) limits the combined execution of coercive-detention orders concerning the same procedural act to six months; it does not prohibit a second order before that maximum has actually been served. The challenged order expressly required credit for any detention served under the earlier order. The Court further found the measure necessary and proportionate given the gravity of the alleged politically motivated violence, E.’s likely knowledge, and the trial court’s duty to ascertain the truth.

Key Takeaways

  • A witness previously convicted by a final judgment ordinarily cannot invoke Section 55(1) to refuse all testimony about the same adjudicated acts.
  • A blanket refusal requires concrete evidence that truthful testimony would create or strengthen a risk of prosecution for another procedural act; conjectural or theoretical risks do not suffice.
  • Multiple coercive-detention orders concerning the same procedural act may be issued, but their combined execution may not exceed six months.

Why It Matters

The decision clarifies the relationship between a witness’s privilege against self-incrimination and the duty to testify after a related conviction has become final. It emphasizes that courts must assess concrete prosecution risks question by question rather than accept a generalized fear arising from the witness’s former membership in a criminal organization.

It also resolves an important issue concerning repeated coercive-detention orders: Section 70(4) regulates the total time actually served, not merely the number or stated duration of orders entered. Courts issuing a later order involving the same procedural act must expressly ensure that combined detention does not exceed six months.
