Questão jurídica principal
Whether the annulment of facilitated naturalization under Art. 41 LN was lawful because it had been obtained by false declarations or concealment of essential facts.
Decisão extraída
The annulment was lawful because the authorities could, without arbitrariness, infer that the declaration of a stable marital union was false or misleading when made.
Fundamentação extraída
The chronological sequence of marriage, naturalization request, later separation, and an extra-marital relationship supported the presumption that the marriage was not genuinely stable at the relevant time. The applicants did not rebut that presumption with a plausible extraordinary event explaining the rapid breakdown.
