Questão jurídica principal
Whether the annulment of facilitated naturalization under Art. 41 LN was lawful
Decisão extraída
The annulment was lawful because the authorities could reasonably infer that the applicant had obtained naturalization through deceptive statements about a stable marital union, and he failed to rebut that presumption.
Fundamentação extraída
The rapid sequence of events—declaration of stable marriage, naturalization, separation, divorce, and a new marriage project—supported a factual presumption of fraud. The applicant's explanations did not make a reasonable alternative plausible.
