Questione giuridica chiave
Whether there was a legally relevant change in health justifying revision of the disability pension
Decisione estratta
No sufficiently proven revision-relevant change occurred; the half pension could not be lifted.
Motivazione estratta
Although the medical reports differed in their descriptions, the MEDAS experts expressly denied any change in health since June 2005, which was not shown to be manifestly incorrect or based on arbitrary assessment.
