Questão jurídica principal
Whether the appeal met the mandatory requirements of Art. 42 BGG and could be examined on the merits.
Decisão extraída
The appeal did not satisfy the minimum requirements because it failed to explain sufficiently how the challenged decision violated federal law.
Fundamentação extraída
The only timely filing did not contain a sufficiently reasoned challenge to the facts or the legal assessment; the later supplementary submission was filed after the appeal deadline and could not be considered.
