Kernrechtsfrage
Whether the insured showed a relevant deterioration justifying a higher disability pension revision.
Extrahierter Entscheid
No legally relevant deterioration of health or earning capacity was proven; the refusal of the increase was upheld.
Extrahierte Begründung
The court relied on the MEDAS report and the later expert report, which did not establish a substantial change since the half pension was granted. The objections based on treating physicians and one private psychiatric opinion were not convincing, especially because treating specialists are generally expected to favor their patients in doubtful cases.
