Questione giuridica chiave
Whether the mutual assistance request satisfied the factual-exposition requirements of TEJUS Art. 29(1).
Decisione estratta
Yes. Read in context of the successive supplements, the request sufficiently identified the investigation, the essential facts, and the need for the evidence.
Motivazione estratta
The Court held that the treaty requires a brief statement of essential facts, including where possible time, place, and manner. The Swiss authority may depart from the requesting state's account only for obvious and immediately established errors. A supplementary request may rely on earlier requests, and the cumulative file made the object and reasons of the request clear.
