Question juridique clé
Whether the appeal met the special admissibility requirement of a particularly important case under Art. 84 LTF.
Solution extraite
The case did not raise a particularly important question; the appeal was therefore not admissible.
Motifs extraits
The arguments on the foreign-law value threshold and lex mitior concerned facts and the merits to be decided by the trial judge, not a question of principle. The detention-conditions complaint did not justify departure from settled case law accepting extradition to Russia with diplomatic assurances.
