Kernrechtsfrage
Whether the applicants had standing to challenge the transfer of witness interview records and other materials.
Extrahierter Entscheid
The applicants lacked standing to contest the transmission of the interview records and most third-party documents.
Extrahierte Begründung
Standing in mutual assistance is limited to persons directly affected by the coercive measure or, exceptionally, bank account holders in certain cases. The applicants were only indirectly affected by the witness statements and third-party records, and no exceptional ground applied.
