Question juridique clé
Whether the cantonal court arbitrarily applied the Valais pleading rules by relying on allegedly unpleaded facts about loss of view and panorama.
Solution extraite
No arbitrariness was shown; the pleaded allegations were sufficient to allow adjudication and proof-taking, and the court could rely on the evidence administered.
Motifs extraits
The allegations under Art. 684 CC met the substantiation required by federal law and were also adequate under cantonal procedure; refusing to invite clarification first would have been unduly formalistic.
