Questione giuridica chiave
Whether the appellant lacked passive standing because SAirGroup was the only debtor of the promised pre-retirement benefits.
Decisione estratta
The appellant was the contracting employer and could be sued for the promised benefits; the employee could claim full performance from her alone.
Motivazione estratta
The employment contract was concluded with the appellant, and the retirement letter was a binding promise within that relationship. In any event, solidarity rules allowed the creditor to pursue one debtor for the whole debt.
