Kernrechtsfrage
Whether the cantonal cassation court properly refused restoration of the appeal period and declared the late cantonal nullity appeal inadmissible.
Extrahierter Entscheid
The refusal was upheld; the medical certificate did not sufficiently prove the reasons for the late filing or absence of gross fault.
Extrahierte Begründung
Under cantonal law, restoration required proof that the debtor was prevented from acting timely or from instructing a third party. The court was entitled to require evidence beyond a general certificate of 100% incapacity and to notify the debtor of the deficiency.
