Question juridique clé
Whether the appeal against the provisional criminal seizure was admissible
Solution extraite
The appeal was admissible because the seizure was a criminal matter decided by a final cantonal authority and caused irreparable harm to the account holder.
Motifs extraits
A provisional seizure temporarily deprives the holder of free disposal over the assets, so it creates irreparable prejudice under Art. 93 lit. a LTF.
