Question juridique clé
Whether the public-law appeal was admissible despite uncertainty about a cantonal remedy against a prosecutor's failure to act
Solution extraite
The appeal was admissible because a cantonal remedy was at least doubtful, and the appellants were directly affected by the seizures.
Motifs extraits
A refusal or undue delay to decide by the competent final cantonal authority is treated as a decision. No clear cantonal remedy existed; the appellants had standing as directly affected account holders/economic beneficiaries.
