Kernrechtsfrage
Whether the insured proved a relevant deterioration of health justifying revision of the disability pension.
Extrahierter Entscheid
No. The medical reports did not objectively establish a notable worsening compared with the prior assessed situation.
Extrahierte Begründung
The treating physician mainly relied on subjective complaints; the former expert report served only as a comparison basis in revision proceedings; a new expertise was not required.
