Key legal question
Whether the facilitated naturalization of A.________ was obtained by false statements or concealment of material facts under Art. 41 BüG.
Extracted holding
The annulment of A.________'s facilitated naturalization was lawful because the timeline showed no stable marital community at the decisive time and she had knowingly given untruthful declarations.
Extracted reasoning
The close sequence of naturalization, separation, divorce, and remarriage supported the inference that the marriage was already broken at the time of the declaration; the authority could rely on factual presumptions and there was no federal-law violation.
