Questione giuridica chiave
Whether the former Swiss-Yugoslav social security agreement still applied to a Kosovar claimant after 1 April 2010
Decisione estratta
The agreement was no longer applicable to Kosovar nationals from 1 April 2010 onward.
Motivazione estratta
Following BGE 139 V 263, Kosovo nationals cannot rely on the former Yugoslav agreement. The respondent's asserted Serbian citizenship was not proven; a lapsed Serbian passport and unclear documents for her husband were insufficient.
