Kernrechtsfrage
Whether the ongoing disability pension could be reduced through revision under Art. 17(1) ATSG.
Extrahierter Entscheid
No. The facts had not materially changed during the relevant period, so a pension revision was excluded.
Extrahierte Begründung
The Federal Court was bound by the lower court's factual finding that there had been no significant change. On that basis, the statutory conditions for revision were not met.
