Questão jurídica principal
Whether the insured person's disability had changed since the initial pension decision so as to justify reducing the pension.
Decisão extraída
The disability had improved enough to reduce the full pension, but only to a half pension from 2003, not to a quarter pension.
Fundamentação extraída
Medical evidence supported a 50% work capacity in adapted light work; however, the canton wrongly assessed the pre-injury income, and correcting that income led to a 55% disability rate.
