Key legal question
Whether the extension request satisfied formal requirements and whether the appellant's right to be heard was violated by lack of file access.
Extracted holding
The hearing right was respected and the request met the formal requirements for extension.
Extracted reasoning
The appellant had already been heard in France under the extradition procedure; the French request included the relevant decision, facts, and legal basis. The late request for the file in Switzerland did not show a denial of access, especially since the appellant was later allowed to consult the file and comment.
