Question juridique clé
Whether the cantonal authority had to hear witnesses about the auction start time and the alleged effect of the creditor's meeting with the office.
Solution extraite
The refusal to take further evidence did not violate federal law; evidentiary assessment is governed by cantonal procedure and is not reviewable under the LP complaint.
Motifs extraits
Except for the principle of free assessment under Art. 20a(2) no. 3 LP, the taking and appraisal of evidence are matters of cantonal procedural law, reviewable only by constitutional complaint for arbitrariness.
