Questione giuridica chiave
Whether the unsigned copy of the cantonal judgment rendered it invalid
Decisione estratta
The missing signature was only a clerical error; the defect was cured by delivery of a properly signed version, so the judgment remained valid.
Motivazione estratta
The court distinguished the case from practice concerning unsigned decisions as a matter of routine. Here the court file contained a signed original, showing the absence of a signature on the copy sent to the appellant was accidental.
