Kernrechtsfrage
Whether the cantonal court erred in finding that the claimant had regained work capacity and lost entitlement to an invalidity pension as of 1 January 2003.
Extrahierter Entscheid
The claimant's arguments did not show any manifestly incorrect factual finding or procedural violation; the finding that pension entitlement ceased was upheld.
Extrahierte Begründung
Under the restricted review applicable, the complaint relied on unsupported allegations and did not displace the file evidence, including salary declaration, anonymous report, and field observations.
