Questão jurídica principal
Whether the revision requirements under Art. 17 ATSG were met due to a material deterioration in health and earning capacity.
Decisão extraída
No material change was proven beyond the increase already recognised by the IV office; the revision basis was therefore limited to the pension level already granted.
Fundamentação extraída
The court accepted that psychiatric evidence established a 40% capacity in the insured's work, but it found no legally relevant additional somatic deterioration compared with the situation underlying the 2002 decision.
