Kernrechtsfrage
Whether the appeal met the minimum reasoning requirements of Art. 42 BGG and could be examined on the merits.
Extrahierter Entscheid
The appeal did not meet the statutory minimum reasoning requirements and was therefore inadmissible.
Extrahierte Begründung
The appellant failed to show, in a concise manner, how the challenged decision violated federal law; his criticism was limited to an unsubstantiated reappraisal of the medical records, which is inadmissible appellatory criticism.
