Questão jurídica principal
Whether the facilitated naturalization could be annulled under Art. 41 LN for fraudulent concealment of the lack of a stable marital union.
Decisão extraída
Yes. The rapid sequence of events supported a factual presumption that the naturalization had been obtained fraudulently, and the applicant did not rebut it.
Fundamentação extraída
Under Art. 41 LN, annulment requires deceptive conduct, not merely the absence of a substantive condition. A factual presumption may arise from the chronology of marriage breakdown and later divorce; the applicant only needed to show a reasonable possibility she had not lied, but the pregnancy, alleged marital stability, and ex-husband's explanations were insufficient.
