In Switzerland, the federal popular initiative "against mass immigration" (German: Eidgenössische Volksinitiative "Gegen Masseneinwanderung", French: Initiative populaire « Contre l'immigration de masse », Italian: Iniziativa popolare "Contro l'immigrazione di massa") was a referendum that aimed to limit immigration through quotas, as it had been prior to the bilateral treaties between Switzerland and the European Union (EU) launched in 2002.
