Kernrechtsfrage
Whether the appellant had standing to challenge transmission of his interrogation transcripts
Extrahierter Entscheid
He was directly affected because he had spoken about his own situation and could invoke his own right to refuse to testify.
Extrahierte Begründung
A person heard as witness may oppose transmission only insofar as the information concerns them personally or they rely on a refusal right; that was the case here.
