Key legal question
Whether the cantonal court could declare an appeal inadmissible immediately because it lacked the original signature.
Extracted holding
No. Under the principle against excessive formalism and good faith, the appellant must be given a short additional period to cure an unsigned appeal, even if the appeal period has expired, absent abuse of rights.
Extracted reasoning
The omission was a readily recognizable procedural defect. Refusing any opportunity to regularize it, although there was no sign of deliberate misuse, was arbitrary and excessively formalistic.
