Key legal question
Whether the cantonal judgment had to be set aside for lack of reasoning under Art. 112 BGG
Extracted holding
The cantonal decision omitted the decisive factual and legal reasons on the disability degree and comparison incomes, so it had to be annulled and remitted.
Extracted reasoning
Under Art. 112 Abs. 1 lit. b and Abs. 3 BGG, a judgment must state the material factual and legal grounds. The cantonal court failed to explain the calculation of the invalidity degree, which prevented federal review.
