Question juridique clé
Whether the Federal Court had jurisdiction over the compensation claims against the private co-defendants.
Solution extraite
The appeal was inadmissible because no substantive judgment on those claims existed; the cantonal court had only referred them to the civil judge.
Motifs extraits
The referral was purely procedural and did not finally determine the merits; under Art. 29 OJ, such a procedural order is not reviewable on federal appeal.
