Question juridique clé
Whether the cantonal court violated the right to be heard by insufficiently addressing the appellants' arguments and evidence.
Solution extraite
The judgment sufficiently dealt with the relevant arguments and evidence; insofar as the complaint merely referred to prior submissions, it was inadequately reasoned.
Motifs extraits
The cantonal court expressly addressed the notary's conduct, the old family-agency disputes, and the evidentiary value of the witness statements; unsupported references to prior briefs do not satisfy the federal pleading requirements.
