Kernrechtsfrage
Whether the medical evidence sufficiently established a significant change in health or earning capacity justifying revision of the disability pension from 1 October 2004
Extrahierter Entscheid
The record did not allow the court to determine whether there had been a relevant change or merely a different assessment of an unchanged condition.
Extrahierte Begründung
Neither the administrative decisions nor the cantonal judgment showed on what medical basis the authorities had concluded that the pension had to be limited in time; the factual findings were insufficient for federal review, requiring remand.
