Key legal question
Whether the accident insurer could revoke the disability pension under Article 17 ATSG on the basis of an alleged improvement in health and work capacity.
Extracted holding
The file did not permit a final ruling on a relevant change in the insured person's condition; further medical clarification was necessary before deciding on revision.
Extracted reasoning
The surveillance footage raised doubts, but the existing medical reports did not resolve whether the observed activities were compatible with the diagnoses underlying the pension. A specialist, possibly multidisciplinary, assessment had to be obtained after confronting the doctors with the recordings.
