Question juridique clé
Whether the extradition appeal presented a particularly significant case under Art. 84 BGG
Solution extraite
It did not; the case raised no fundamental legal question and had no exceptional significance.
Motifs extraits
The lower court addressed the objections; its reasoning revealed no federal-law violation. In particular, the alleged Russian amnesty did not create an extradition bar because it was for the Russian authorities to decide whether it applied, and they had not withdrawn the request.
