Questão jurídica principal
Whether the extradition request satisfied the formal requirements and allowed review of dual criminality
Decisão extraída
The translated request was linguistically unclear and insufficiently reliable, so the authorities could not properly review dual criminality.
Fundamentação extraída
The request and annexes must let the Swiss authority assess the relevant extradition conditions. Here the description of the facts was too confusing and inconsistent to support a sound legal assessment.
