Questione giuridica chiave
Whether the federal appeal met the formal reasoning requirements of Art. 42 LTF
Decisione estratta
No. The filing did not sufficiently explain, against the cantonal judgment, why the finding of late opposition and no restitution of the deadline was unlawful.
Motivazione estratta
The cantonal judgment addressed only procedural admissibility, but the appellant mainly argued the merits of entitlement to accident benefits and merely repeated why the opposition deadline was missed. This is not a valid, topically reasoned appeal.
