Key legal question
Whether the federal appeal complied with the requirement to state reasons under Art. 42 BGG.
Extracted holding
The appeal did not sufficiently explain, with reference to the cantonal court's reasoning, why the findings were erroneous or unlawful.
Extracted reasoning
The filing merely disputed the assessment of work capacity, income comparison, and disability deduction in an appellatory manner, without showing obvious factual error or legal violation as required by Art. 97 and 95 BGG.
