Questão jurídica principal
Whether the cantonal court violated the right to be heard by refusing evidence on the amount the employee might obtain in SAirGroup's concordat.
Decisão extraída
No. The requested fact was future and legally irrelevant because the creditor could claim full performance from either solidary debtor, subject only to amounts already received.
Fundamentação extraída
The complaint did not identify a concrete piece of evidence, and the amount recoverable from the other debtor did not matter for the dispute.
