Kernrechtsfrage
Whether the private complainant had standing to bring an eidgenössische Nichtigkeitsbeschwerde under Art. 270 lit. g BStP.
Extrahierter Entscheid
Yes. In a principal private prosecution for defamation under Zurich procedure, the public prosecutor is not involved, so the complainant was entitled to file the federal nullity complaint.
Extrahierte Begründung
The cantonal procedure assigns the prosecution entirely to the private complainant; therefore the case falls within Art. 270 lit. g BStP.
