Key legal question
Whether the facilitated naturalization was obtained by deceit under Art. 41 BüG
Extracted holding
The naturalization was obtained by deceit because the marriage was no longer a genuine, stable community at the relevant time and the applicant concealed that fact.
Extracted reasoning
The close sequence of events, the later affair, divorce, and remarriage supported the presumption that marital will had already ceased by naturalization; the applicant did not rebut this.
