Key legal question
Whether the residence permit had to be renewed under Art. 50(1)(a) AuG after divorce.
Extracted holding
No. Because the marriage was found to be a sham marriage, no protectable residence-right claim arose or it had lapsed.
Extracted reasoning
On a holistic assessment of indications and the former spouse's self-incriminating statements, the marriage was concluded for immigration purposes only, triggering Art. 51(1)(a) and (2)(a) AuG.
