Kernrechtsfrage
Whether the cantonal court violated the appellants' right to be heard by deciding without giving access to the service documents and translations concerning notification of the default judgment.
Extrahierter Entscheid
Yes. Because the notification date was decisive, the service documents and their translations had to be disclosed and the parties had to be allowed to comment on them.
Extrahierte Begründung
The documents were central to determining timeliness. The record did not show that the appellants had been able to consult them or respond to them at any stage, and the appellate court ignored their explicit request for access and a supplementary deadline.
