Key legal question
Whether the request was sufficiently motivated to satisfy dual criminality requirements
Extracted holding
Yes. The supplementary request described a customs/tax fraud scheme with enough clarity to permit recognition of an offence equivalent to fiscal fraud under Swiss law.
Extracted reasoning
Although the facts were somewhat confusing, the description of the diamond-carrousel scheme, false invoices, substitutions, and structured evasion of taxes sufficiently justified assistance; the court accepted the Cantonal court's revised assessment.
