Questão jurídica principal
Whether the cantonal court committed a formal denial of justice by not deciding the validity of the guarantee call and the existence of another secured claim.
Decisão extraída
No. The current-account debt alone meant the pledge had not extinguished, so the cantonal court did not need to rule on the disputed guarantee claim.
Fundamentação extraída
Under Art. 889(2) CC, the pledgee must return the pledged assets only after being fully paid. Because an undisputed current-account debt remained unpaid, the bank still had a secured claim, and the pledge remained in force in full.
