Kernrechtsfrage
Whether the private prosecutor had standing to file an eidgenössische Nichtigkeitsbeschwerde in a Zürich defamation case.
Extrahierter Entscheid
Yes. In principle private-prosecution defamation proceedings under Zürich law are brought solely by the private prosecutor, so standing exists under Art. 270 lit. g BStP.
Extrahierte Begründung
The public prosecutor is not entitled to indict in such proceedings; the complainant steps into the role of the public accuser from the outset.
