Question juridique clé
Whether the cantonal order requiring USTRA to produce documents in arbitration was appealable to the Federal Tribunal.
Solution extraite
The challenged cantonal decision was not directly appealable to the Federal Tribunal because the cantonal judge acted as supporting authority in a single and final instance.
Motifs extraits
Evidence-assistance decisions under the CPC by the supporting state authority are rendered in a single, definitive instance; the remedy indication in the cantonal order could not create Federal Tribunal jurisdiction.
