Key legal question
Whether the insured's health had worsened since the 2005 pension review so as to justify a higher invalidity pension
Extracted holding
There were significant doubts about the medical assessment; further investigations were required before deciding the revision request.
Extracted reasoning
The record showed potential worsening related to leg edema and musculoskeletal limitations. Existing reports were incomplete and partly contradictory, and it was unclear whether the edema had been medically assessed and how it affected work capacity.
