Questão jurídica principal
Whether the debt collection proceeding was null because it constituted an abuse of rights
Decisão extraída
Only in exceptional cases can a debt collection be null for abuse of rights; here no exceptional circumstances were shown, so the proceeding was not abusive.
Fundamentação extraída
The office had to serve the payment order if the request met formal requirements. The existence or validity of the claim is not examined at this stage, and the facts suggested a possible contractual damages claim, even if the creditor may also have wanted to exert pressure.
