Questione giuridica chiave
Whether the public-law appeal was filed within the statutory time limit.
Decisione estratta
The appeal period runs from notification of the challenged decision, not from later communication of remedies; the appeal was therefore late.
Motivazione estratta
No legal duty to indicate remedies existed for this extraordinary remedy, and the later letter did not amount to a new decision, correction, or supplementation that would restart the deadline.
