Question juridique clé
Whether Swiss or Burundian law governed the divorce of a spouse with multiple nationalities and a Swiss domicile
Solution extraite
Swiss law applied because the wife’s effective nationality was Swiss and, in any event, she was domiciled in Switzerland when the action was filed.
Motifs extraits
Under LDIP, the common foreign nationality only displaces Swiss law if it is the effective nationality. The court upheld the cantonal assessment that the wife’s strongest ties were with Switzerland, given her long residence there, her decision to settle there permanently, and her naturalization.
