Question juridique clé
Whether the request disclosed sufficiently justified suspicion of tax fraud enabling mutual legal assistance.
Solution extraite
The request did not describe an astute fraudulent scheme; mere non-documentation or lack of accounting was insufficient.
Motifs extraits
Mutual legal assistance for tax fraud requires sufficiently substantiated suspicion of an offense involving astute deception. The facts alleged showed at most an attempt to conceal taxable profits and the use of offshore structures, but not the concrete deceptive manoeuvre needed under Swiss law.
