Kernrechtsfrage
Whether the final collocation plan could be corrected ex officio after it had become final.
Extrahierter Entscheid
A final collocation plan may be reopened ex officio only in exceptional cases for weighty reasons; here the correction was permissible because the earlier plan had not expressly and unmistakably ruled on the mortgage issue and no special notice had been served.
Extrahierte Begründung
A final collocation decision is generally immutable, but the rule does not apply where the bankruptcy office merely overlooked a matter and never formally denied the lien claim. Since the lien status had not been decided in a clear way, the plan did not become final on that point.
