Question juridique clé
Whether the banks were entitled to appeal the prosecutor's order under cantonal criminal procedure
Solution extraite
They were not directly and personally affected by the challenged order and therefore lacked standing.
Motifs extraits
The order only invited the accused to submit evidence hypotheses and did not itself impose any document-production duty on the banks; any later evidentiary steps remained reserved. Formal notification and a legal-remedy notice did not create standing.
