Kernrechtsfrage
Whether the German request met the formal requirements of mutual legal assistance requests.
Extrahierter Entscheid
The request was sufficiently specific in light of the case and the known documents; the formal requirements were satisfied.
Extrahierte Begründung
The purpose of the formal rules is primarily to protect the requesting state; the Swiss executing authority knew the relevant file and the appellants could not be misled about the scope of the request.
