Questão jurídica principal
Whether the federal appeal met the motivation requirements under Art. 42 and 108 LTF.
Decisão extraída
No. The appellant challenged only the timeliness of the written appeal brief but did not contest the separate ground that the declaration of appeal was itself late.
Fundamentação extraída
Where the challenged decision rests on independent alternative grounds, the appellant must show that each ground is unlawful. Because one sufficient ground remained unchallenged, the appeal was manifestly insufficiently reasoned.
