Question juridique clé
Whether the claimant remained entitled to an IV pension after his AHV contributions were refunded/transferred to Turkey.
Solution extraite
No. Once the AHV contributions were transferred to the Turkish social insurance system, no further claim to Swiss AHV/IV benefits could be derived from them.
Motifs extraits
The court held that contribution refund under the Swiss-Turkish social security agreement and the relevant AHV rules extinguishes any future Swiss pension claim based on those contributions; the amounts are to be credited under the Turkish system instead.
