Kernrechtsfrage
Whether the IV office could reduce the disability pension without clarifying the effects of the SUVA assessment
Extrahierter Entscheid
The IV office had to take the SUVA assessment into account and obtain its file and reasoning before deciding on the revision.
Extrahierte Begründung
A final disability assessment by another social insurer cannot be ignored; it must be treated as an important indication and incorporated into the assessment. The IV office therefore breached its duty to investigate by not clarifying the SUVA findings.
