Questione giuridica chiave
Whether the cantonal court arbitrarily applied the Valais pleading rules by relying on allegedly unpleaded facts about loss of view and panorama.
Decisione estratta
No arbitrariness was shown; the pleaded allegations were sufficient to allow adjudication and proof-taking, and the court could rely on the evidence administered.
Motivazione estratta
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.
