Question juridique clé
Whether the Federal Supreme Court could hear a direct appeal against the cantonal decision on provisional evidence preservation.
Solution extraite
The appeal was inadmissible because the challenged decision was an interlocutory decision not meeting the conditions for immediate federal review.
Motifs extraits
The order granting an expert opinion in autonomous provisional evidence proceedings did not end the case. The appellants failed to show a non-reparable legal prejudice under Art. 93(1)(a) BGG, and Art. 93(1)(b) BGG was also unavailable because, after a non-entry decision below, the Federal Supreme Court could not decide the merits itself.
