Questão jurídica principal
Whether the denial of an invalidity pension should be upheld based on the assessed residual work capacity and income comparison.
Decisão extraída
The denial could not be upheld; the correct income comparison yielded an invalidity degree of 43%, entitling the insured to a quarter disability pension.
Fundamentação extraída
The court accepted a residual work capacity of 75% as the midpoint between 70% and 80%, used the more concrete validated income from the specialized job, and found that this produced a pension-relevant loss of earnings despite a 10% deduction.
