Questione giuridica chiave
Whether the federal appeal satisfied the formal requirements of Art. 42 BGG and was filed within time.
Decisione estratta
The appeal did not meet the statutory requirements; no supplemental filing was made within the appeal deadline.
Motivazione estratta
The appellant merely repeated prior arguments and did not explain how the challenged decision violated federal law. The deadline had expired without correction, so the appeal was manifestly deficient.
