Questione giuridica chiave
Whether the Belgian request was sufficiently motivated and met double-criminality requirements
Decisione estratta
The supplemented request sufficiently described the modus operandi and the company's alleged role, allowing the Swiss authorities to accept a customs fraud amounting to tax fraud.
Motivazione estratta
Although the first request was too sparse, the later supplement clarified the diamond-routing scheme, false invoices, and the company's alleged role as a shell company. The conduct described constituted a customs offence equivalent to tax fraud, so mutual assistance was not barred by the tax-offence exclusion.
