Questione giuridica chiave
Whether the German request concerned abgabebetrug and thus allowed mutual legal assistance
Decisione estratta
Yes. The described conduct amounted to customs fraud under Swiss law and therefore did not fall under the fiscal-offence refusal ground.
Motivazione estratta
False invoices with underdeclared horse prices were documentary evidence in customs proceedings; their systematic use constituted deceitful conduct, not mere tax evasion.
