Question juridique clé
Admissibility of the federal appeal against an interlocutory seizure order
Solution extraite
The appeal was admissible only as a constitutional-law appeal insofar as it raised constitutional grievances; otherwise it was inadmissible for lack of proper motivation.
Motifs extraits
A seizure decision is an incidental measure and may be challenged only if irreparable harm is shown. When the challenge concerns a provisional measure, only constitutional rights can be invoked and must be argued specifically.
