Key legal question
Whether the appeal is admissible in a mutual assistance case under Art. 84 BGG
Extracted holding
The case was not particularly important within the meaning of Art. 84 BGG, so the appeal was inadmissible.
Extracted reasoning
The request concerned information from the secret sphere, but the appellants did not show any element justifying a particularly important case. Their arguments on Art. 2 IRSG, dual criminality, and alleged abuse of proceedings were unconvincing or unsupported.
