Kernrechtsfrage
Whether the appeal against the partial cantonal judgment ordering disclosure to B. was admissible
Extrahierter Entscheid
The appellant was not the addressee of that partial judgment and could not challenge the lack of a ruling on joinder through this appeal.
Extrahierte Begründung
The contested decision imposed obligations only on the State and did not determine the appellant's joinder status; he therefore lacked a sufficient legal interest in that specific ruling.
