Key legal question
Whether a revision ground under Article 17 ATSG existed due to a material change in health or work capacity
Extracted holding
No material change in the relevant facts or a sufficiently increased work capacity was shown.
Extracted reasoning
The court held that the later medical opinion and the insured's reported functional improvements showed at most a slightly better health state, but not a substantial improvement in earning capacity; the case was one of different assessment of largely unchanged facts.
