Questão jurídica principal
Whether the husband's action to challenge paternity was an abuse of rights under Art. 2(2) CC
Decisão extraída
The action was not abusive on the specific facts and had to be assessed case by case.
Fundamentação extraída
Art. 2(2) CC requires consideration of the concrete circumstances. The husband's marriage to a pregnant woman is not legally equivalent to an acknowledgment of paternity or consent to conception by a third party, and no fixed rule bars the claim.
