Kernrechtsfrage
Whether the appeal met the 'particularly important case' requirement under Art. 84 LTF.
Extrahierter Entscheid
The case did not present special importance: it concerned only documents relating to three specified bank accounts, and no legal question of principle arose.
Extrahierte Begründung
Although secret information was involved, the requested transmission was limited and the appellants failed to show any exceptional ground under Art. 84 LTF.
