Supreme Court allows bankruptcy administrator's appeal to recover costs from insolvent debtor.

The Supreme Court of Poland accepted the bankruptcy administrator's cassation appeal against the lower court's dismissal of the claim for payment. The administrator argued that the debtor failed to justify the expenses incurred during the insolvency proceedings, while the debtor contended the costs were necessary for asset preservation. The court ruled that the debtor must substantiate the necessity and proportionality of such expenditures to avoid unjust enrichment.
