Key legal question
Whether the special investigating office had standing to file an eidgenössische Nichtigkeitsbeschwerde.
Extracted holding
The special investigating office was entitled to act as the cantonal public prosecutor for the cases definitively assigned to it and therefore had standing to file the federal cassation appeal.
Extracted reasoning
Under the cantonal rules, the office combined investigative and prosecutorial powers within its field of competence and acted independently of the ordinary prosecution service; no supervisory or instruction power of the latter remained.
