Whether the debtor had capacity to sue in the definitive debt-enforcement proceedings and whether this had to be examined ex officio.
Capacity to sue had to be examined ex officio; the lower court erred by relying on the criminal judgment and by not investigating the current state of discernment further.
Civil procedural capacity under Arts. 59, 60 and 67 CPC depends on civil capacity and discernment. The criminal court's finding of inability to participate in criminal proceedings did not settle civil capacity, which is relative and act-specific. The record contained reasons to doubt discernment, so the presumption of capacity was not sufficient.
