Kernrechtsfrage
Whether the appellant met the three-year minimum contribution period for an ordinary Swiss invalidity pension.
Extrahierter Entscheid
Foreign contribution periods in Germany could not be credited; the minimum contribution period was not met.
Extrahierte Begründung
The applicable rules required three years of contributions under Swiss law. The Yugoslavia social security agreement did not extend to the FZA or its coordination regulations, and its equality clause did not permit importing those rules. The special provision for certain former Yugoslav nationals did not apply because the appellant had not remained in Switzerland and no AVS/AI contributions continued.
