Questione giuridica chiave
Whether the cantonal court had to address the alleged failure to grant a grace period for the cost advance under cantonal procedure.
Decisione estratta
No. Because both non-payment of the cost advance and unexcused absence from the hearing independently justified contumacy under cantonal law, the alleged omission about a grace period did not matter.
Motivazione estratta
Under Art. 125 ZPO/GR, either non-appearance at the main hearing or failure to pay the required advance is sufficient for the contumacy procedure. Both grounds were present on the unchallenged facts.
