Key legal question
Whether the cantonal court violated the right to be heard by not ordering further witness and expert evidence.
Extracted holding
The right to be heard was not violated because the claimant had not duly requested those specific measures in the cantonal proceedings, and the court could decide on the existing record.
Extracted reasoning
A party must offer the evidence it considers necessary in due time. The cantonal court was entitled to rely on the file and did not need to order further evidence ex officio.
