Questão jurídica principal
Whether the facilitated naturalization was obtained by false declarations or concealment of essential facts under Art. 41 LN.
Decisão extraída
Yes. The applicant concealed essential facts and made false declarations about his family situation and criminal record, so annulment was justified.
Fundamentação extraída
A lasting double life and the failure to disclose an extramarital child showed deception; the drug conviction also contradicted his declaration of respect for Swiss law. These facts independently sufficed to establish fraudulent acquisition.
