Kernrechtsfrage
Whether the appeal met the formal requirements of Art. 42 BGG and could be considered on the merits.
Extrahierter Entscheid
The filing did not contain a legally sufficient request or a sufficiently issue-specific reasoning and failed to engage with the lower court's findings in a concrete way.
Extrahierte Begründung
Under Art. 42 BGG, an appeal must state requests and reasons showing in what respect the challenged decision violates federal law. The appellant did not substantively address the lower court's reasoning, including the new registration for an invalidity pension and the income comparison, nor did he show a violation under Art. 95 f. BGG or an obviously incorrect fact-finding under Art. 97(1) BGG.
