Key legal question
Whether the cantonal and federal supervisory authorities had to order a new valuation of the property
Extracted holding
No. The complaint did not show that the cantonal authority exceeded or abused its discretion when relying on the expert valuation.
Extracted reasoning
Property-valuation disputes are finally decided by the cantonal supervisory authority; federal review is limited to violations of federal procedural rules or abuse/excess of discretion. The debtor failed to demonstrate any such error, and several objections were either legally irrelevant or factual challenges inadmissible in this procedure.
