Kernrechtsfrage
Whether the surveillance of the insured person was lawful and usable.
Extrahierter Entscheid
The surveillance was objectively justified by concrete indications of possible exaggeration or simulation, and its results were not excluded from the file.
Extrahierte Begründung
The court held that an 'initial suspicion' in the criminal-law sense was not required; objective justification sufficed. The file contained indications from medical sources supporting doubts about the reported limitations.
