Key legal question
Whether the appeal against the cantonal decision on provisional evidence was admissible before the Federal Supreme Court.
Extracted holding
The challenged cantonal decision ended an autonomous provisional-evidence proceeding and was therefore a final decision; civil appeal was in principle admissible.
Extracted reasoning
A provisional-evidence decision is a final decision when issued in a self-contained proceeding independent of any main action; it is not a mere interim measure tied to pending merits proceedings.
