Kernrechtsfrage
Whether the cantonal court had to order further rheumatological medical investigations
Extrahierter Entscheid
No further rheumatological examination was required because the medical records were sufficiently consistent and such an examination was not likely to produce additional relevant findings.
Extrahierte Begründung
The court relied on concordant reports from multiple doctors and found the existing file adequate; it upheld the lower court's anticipatory evaluation of evidence.
