Key legal question
Whether the facts alleged by France satisfy double criminality for extradition under Swiss law.
Extracted holding
Yes. The surveillance, reconnaissance, and possession of weapons described in the request amounted to preparatory acts within the meaning of Art. 260bis CP.
Extracted reasoning
For extradition, the Swiss authority is bound by the facts stated in the request absent manifest inaccuracies. Those facts showed concerted reconnaissance and material steps indicating a process moving beyond mere discussion toward execution.
