Question juridique clé
Whether the requirements for revising and terminating the invalidity pension were met under changed health circumstances.
Solution extraite
The evidence did not establish a sufficiently proven material change in health or work capacity compared with the 2003 pension award.
Motifs extraits
The later expert report described diagnostic changes and some deterioration, but it did not clearly distinguish an actual factual change from a mere new assessment of largely unchanged findings. For revision under Art. 17 ATSG, the court requires a reliable comparative assessment of earlier and current medical facts, which was lacking.
