Questione giuridica chiave
Whether the debt collection was null because it allegedly constituted an abuse of rights under Art. 2(2) CC
Decisione estratta
Nullity for abuse of rights is exceptional and was not established here; the complaint merely attacked the underlying claims, which must be decided by the competent merits courts.
Motivazione estratta
The existence and debtor status of the claims were disputed in parallel civil and criminal proceedings. The surveillance authority could not substitute itself for the trial courts to determine whether the claims were well-founded.
