Kernrechtsfrage
Whether the appeal could rely on objections already rejected in earlier decisions concerning the admissibility of mutual legal assistance.
Extrahierter Entscheid
No. In a supplementary closure decision, only arguments that could not have been raised earlier, especially those concerning execution, are admissible.
Extrahierte Begründung
The appellant merely repeated complaints already finally dismissed in earlier proceedings; such arguments cannot be reconsidered at this stage.
