2014 Swiss immigration initiative

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.

The popular initiative was launched by the national conservative Swiss People's Party and was accepted by a majority of the electorate (50.3%, a difference of 19,526 votes) and a majority of the cantons (14.5 out of 23; 12 of 20 full cantons plus five of six half cantons) on 9 February 2014. This initiative was mostly backed by rural parts (57.6% approvals) of Switzerland as well as by a strong majority (69.2% approvals) in the Italian-speaking canton of Ticino, while metropolitan centres (58.5% rejection) and the French-speaking part (58.5% rejection) of Switzerland rejected it.

Swiss-EU bilateral treaties on single market participation are all co-dependent; if one is terminated, then all are terminated. Consequently, should Switzerland choose unilaterally to cancel the free movement agreement, then all its single market agreements with the EU will lapse unless a compromise is found. On 22 December 2016, Switzerland and the EU concluded an agreement that a new Swiss law (in response to the referendum) may require Swiss employers to give priority to Swiss-based job seekers (Swiss nationals and foreigners registered in Swiss job agencies) but does not limit the free movement of EU workers to Switzerland.
