Question juridique clé
Whether the residence permit could be revoked after the marital relationship had effectively ended.
Solution extraite
Yes. The permit was derived from the marital relationship and could be revoked once the marriage had materially broken down and the permit was invoked only formally to maintain residence rights.
Motifs extraits
The free-movement-based derived right exists only while the marriage formally continues and is not abused. Once the spouses had definitively separated and the wife clearly wanted a divorce, the appellant relied on a merely formal marriage to circumvent immigration rules.
