Kernrechtsfrage
Whether the complainant had standing to challenge the dismissal on the merits
Extrahierter Entscheid
He had no standing to contest the merits because the refusal to act on a denunciation does not affect legally protected interests; supervisory rules protect institutional functioning only.
Extrahierte Begründung
Public-law recourse is open only to a person legally affected. A decision not to enter into or reject a denunciation is not a decision regulating legal relations, and judicial supervision provisions do not confer individual rights.
