Questão jurídica principal
Whether the reduction of the whole invalidity pension to a three-quarter pension was lawful under the revised IVG transitional rules.
Decisão extraída
The reduction could not stand on the existing file because the authority had not sufficiently clarified whether the insured person's condition had changed since the earlier assessment.
Fundamentação extraída
A pension revision requires a legally relevant change in facts; given the six-year gap between the MEDAS report and the contested decision, relying only on internal medical-service assessments was insufficient. Additional specialist examinations were necessary.
