Key legal question
Whether the cantonal court acted arbitrarily in refusing restoration of the missed deadline
Extracted holding
No. An unreasoned medical certificate alone did not make an unavoidable impediment plausible, and the applicant failed to explain the nature and extent of the illness or why no third party or extension request was possible.
Extracted reasoning
Under cantonal procedural law, the applicant had to allege and prove the restoration grounds. The court could require more than a bare certificate and was not required to infer even slight fault or seek the opponent's position without sufficient factual basis.
