Question juridique clé
Whether Portuguese contribution periods from 1971 to 1973 had to be counted for the invalidity pension calculation.
Solution extraite
No. Only the contribution periods recognized by the Portuguese authorities could be counted; Swiss law could not be used to add periods not confirmed by Portugal.
Motifs extraits
Under the applicable coordination rules and the Swiss-Portuguese convention, periods completed in Portugal must be assessed according to Portuguese law. The Portuguese authorities confirmed 264 contribution months and expressly denied any recorded contributions for the disputed period.
