Kernrechtsfrage
Whether the record sufficiently established the insured person's work capacity from April 2003 without additional medical evidence.
Extrahierter Entscheid
The factual findings on remaining work capacity were binding and did not justify further investigations; anticipatory weighing of evidence was permissible.
Extrahierte Begründung
The Federal Court found no substantiated challenge showing obvious inaccuracy or legal error in the cantonal court's assessment of the medical evidence.
