Question juridique clé
Whether the insured person proved a rent-relevant deterioration of health between the 2010 pension decision and the 2013 refusal to increase the pension.
Solution extraite
No. The medical evidence remained sufficient to support a continuing 50% work capacity in adapted work, so no relevant change in circumstances was shown.
Motifs extraits
The cantonal court could rely on the 2012 MEDAS expertise and the psychiatrist's clarifying statement from September 2013. The reported somatic worsening did not alter the overall work capacity, because psychiatric incapacity had already been assessed at 50% in 2010. No arbitrary assessment or procedural defect justified further evidence.
