Key legal question
Whether the cantonal court violated the duty to investigate and the right to be heard by not ordering an independent medical expertise.
Extracted holding
No. The court could rely on the existing file because an anticipatory assessment of evidence showed that further evidence would not change the result.
Extracted reasoning
The allegations under Art. 43(1) LPGA and Art. 29(2) Cst. merged with the evidentiary assessment issue; the file already allowed a well-founded conclusion.
