Key legal question
Whether the complainant had standing to challenge the dismissal on the merits
Extracted holding
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.
Extracted reasoning
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.
