Key legal question
Whether the refusal to increase the invalidity pension should be annulled and a full pension granted
Extracted holding
The pension could not be increased because neither the health condition nor its impact on earning capacity had worsened.
Extracted reasoning
The cantonal findings were binding and showed no relevant deterioration. The MEDAS expert opinion of 19 June 2003 remained decisive, establishing 50% work capacity for suitable light to medium work, while the claimant’s objections merely repeated arguments already rejected and did not demonstrate a manifestly incorrect factual assessment or a violation of federal law.
