Questão jurídica principal
Whether the cantonal court correctly declared the appeal inadmissible for lack of motivation, conclusions, and signature.
Decisão extraída
Yes. The appeal before the cantonal court was not properly completed within the time limit, so the court rightly refused to enter into the merits.
Fundamentação extraída
The submissions after the defect-warning concerned only the merits and did not justify the failure to cure the formal defects in time. Later filings after expiry of the appeal period could not be considered.
