Key legal question
Whether the lecture and its organization occurred publicly within Art. 261bis StGB
Extracted holding
Yes. A gathering is public when it is not confined to a private circle of family, friends, or similarly trust-based personal relationships; a closed invitation-only extremist meeting of 40-50 persons was still public.
Extracted reasoning
For Art. 261bis StGB, publicity is determined by whether the conduct falls outside the private sphere, not by a fixed numerical threshold. Shared ideology, invitation screening, and closed access do not by themselves create privacy if participants are not personally connected.
