Key legal question
Whether the insured person's health had materially worsened since the 2005 decision so as to justify a pension revision.
Extracted holding
No material change in health or work capacity was shown; the 50% work capacity remained.
Extracted reasoning
The 2012 multidisciplinary assessment and RAD view supported a continued 50% capacity in the former occupation and in light work. Additional diagnoses and changed labels did not alter the decisive functional assessment.
