Question juridique clé
Whether the public law appeal against the interlocutory order was admissible despite its preparatory nature.
Solution extraite
Yes. The order was a cantonal final decision; because it threatened use of public force, it could cause irreparable legal harm.
Motifs extraits
An interlocutory evidence order is directly attackable only if irreparable prejudice may result. The threat of public force, like a criminal sanction, creates such prejudice because it cannot be effectively prevented or undone in time.
