Kernrechtsfrage
Whether the federal appeal met the reasoning requirements of Art. 42 BGG.
Extrahierter Entscheid
The appeal did not sufficiently engage with the decisive reasons of the cantonal judgment and was therefore inadmissible in simplified procedure.
Extrahierte Begründung
The appellant merely asserted he had been symptom-free before the accident, without addressing the cantonal court's key findings on non-reviewability of the reconsideration request, expiry of the revision period, and lack of natural causal connection.
