Key legal question
Whether the facilitated naturalization could be declared void under Art. 41 BüG for being obtained by concealment of relevant facts.
Extracted holding
Yes. Concealing serious criminal conduct that existed before naturalization, even if not yet discovered by the authorities, constitutes deception under Art. 41 BüG.
Extracted reasoning
The decisive point is the applicant's actual conduct, not whether the offences had already been uncovered. The duty of candor includes informing the authorities of conduct the applicant knew or had to know was relevant to naturalization.
