Kernrechtsfrage
Whether the applicants had standing to challenge the cantonal mutual legal assistance decision
Extrahierter Entscheid
Only persons personally and directly affected by the mutual legal assistance measures may appeal; mere economic interest or being named in the foreign investigation is insufficient.
Extrahierte Begründung
The account holders were the two companies, not the applicants. B.________ was neither account holder nor economically entitled. A.________ and C.________ failed to prove the alleged liquidation of the companies with official evidence, so no exceptional derivative standing arose.
