Questão jurídica principal
Whether the appellants had standing and the federal appeal was admissible against the interim seizure decision.
Decisão extraída
The appellants had a legally protected interest as account holders, and the appeal was admissible despite the interlocutory nature of the seizure order.
Fundamentação extraída
A decision maintaining or refusing a criminal seizure is interlocutory, but it normally causes irreparable harm because the holder is temporarily deprived of the use of the assets; the appeal was timely and directed against a final cantonal instance decision.
