Key legal question
Whether the federal appeal satisfied the reasoning requirements of Art. 42 BGG.
Extracted holding
No. The filing mainly challenged factual findings in an appellatory way and did not concretely address the cantonal court's reasoning on the required change in invalidity or the underlying income comparison.
Extracted reasoning
An appeal must state requests and reasons and show, in concise form, how the challenged decision violates law. The appellant failed to explain why the factual findings were manifestly incorrect or based on legal error.
