Key legal question
Whether the refusal to take evidence on the amount the employee would receive in SAirGroup's concordat violated the right to be heard or cantonal procedure.
Extracted holding
No violation was shown: the requested evidence concerned a legally irrelevant future amount, and the complaint was insufficiently reasoned.
Extracted reasoning
The amount potentially received from another solidary debtor did not need to be established because the creditor may claim full performance from one debtor and need deduct only what has already been received.
