Kernrechtsfrage
Whether U.________ and C.________ had standing to challenge the transfer of the witness transcript and bank documents.
Extrahierter Entscheid
They lacked standing to challenge the transcript, and thus their appeal was inadmissible in full; only M.________ had standing regarding its own bank documents.
Extrahierte Begründung
Standing to attack witness transcripts belongs, as a rule, only to the witness directly affected. Third parties touched by the statements are not entitled to complain, unless transcript transfer effectively circumvents review of account-document transfer. That exception was not shown.
