Kernrechtsfrage
Whether the administrative-law appeal against the closure decision in mutual legal assistance was admissible.
Extrahierter Entscheid
The appeal was admissible against the closure decision, but the challenged act had to be treated as an inadmissible, overly broad entry-and-execution decision because it left the scope of assistance undefined.
Extrahierte Begründung
The decision authorized general consultation and copying of unspecified documents without a precise document list, preventing review of proportionality and proper judicial control.
