Key legal question
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.
Extracted holding
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.
Extracted reasoning
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.
