Question juridique clé
Whether the appeal met the threshold of a particularly important case under Art. 84 LTF for extradition detention matters.
Solution extraite
No. The appellant did not show any issue of principle or serious defect warranting Federal Supreme Court review.
Motifs extraits
Extradition detention is reviewed only prima facie at this stage; alleged errors about the foreign penal provision and double criminality concern the merits of extradition, not the legality of detention. The supposed abrogation of the cited Russian provision did not make the case particularly important.
