Questione giuridica chiave
Whether the appeal against the cantonal judgment was timely for the parts not covered by the correction decision
Decisione estratta
The appeal was late insofar as it attacked parts of the 11 September 2012 judgment not affected by the 18 December 2012 correction.
Motivazione estratta
A later corrected judgment starts a new time limit only for the points actually corrected. The original appeal period for all other parts had already expired.
