Key legal question
Whether the insured's circumstances had changed in a revision-relevant way since the final 2003 pension denial
Extracted holding
No revision-relevant change was shown; the medical and economic situation did not justify a new pension entitlement.
Extracted reasoning
The court accepted the later expert report of Institut Y. and found no credible worsening. The contrary assessments were unconvincing, and the insured remained able to work 80% in suitable light work.
