Questione giuridica chiave
Whether the constitutional complaint was admissible despite the missing signature being cured only after the deadline.
Decisione estratta
No. The appellant did not cure the signature defect within the time limit, and the later letter could not be treated as a valid appeal because the appeal period had already expired.
Motivazione estratta
Under Art. 42 para. 5 LTF, an unsigned filing must be signed by the party or a lawyer within the prescribed deadline. The later submission came after the non-extendable appeal period under Art. 100 para. 1 LTF had long expired.
