Questão jurídica principal
Whether the insured person's pension should be reduced from a full pension to a quarter pension as of 1 January 2006.
Decisão extraída
The reduction was lawful because the insured person's health had improved and she had a 60% work capacity in her previous occupation without loss of performance.
Fundamentação extraída
The court accepted the expert evidence and held that, under the applicable invalidity comparison, the relevant question was whether the claimant could use the remaining capacity on the balanced labour market. Since no reduced performance was established, the income with disability corresponded to 60% of the income without disability, producing a 40% invalidity rate.
