Question juridique clé
Whether the federal appeal could be entered into despite the cantonal court's dismissal of the claim for lack of substantiated damage
Solution extraite
The appeal could not be examined because the cantonal court's alternative reasoning on insufficient substantiation of damage was sufficient to sustain the judgment.
Motifs extraits
The Federal Supreme Court held that it did not need to review the primary reasoning on absence of damage, since the independent alternative ground of insufficient substantiation alone upheld the decision, and no violation of federal law in that respect was shown.
