The initiative would have required Switzerland to keep its permanent resident population below 10mn before 2050. The federal page said the measure would have required strict limits, including on asylum and residence, and could have forced Switzerland to terminate international treaties if the population threshold was exceeded. The Federal Council and Parliament opposed the initiative, saying it threatened Switzerland's bilateral route with the European Union and created uncertainty for prosperity and internal security.

AP reported that the proposal was promoted by the Swiss People's Party, which argued that population growth was adding pressure to housing, infrastructure and public services. The Guardian reported that the measure would have affected family reunification, residence permits and asylum policy, and could have required Switzerland to leave its free-movement agreement with the EU if the population crossed 10mn before 2050.

That treaty consequence made the referendum more than a domestic population target. Switzerland is not an EU member, but its bilateral agreements with the bloc shape labour mobility and market access. The Federal Council's opposition argument, published by the justice department, was that the initiative would endanger that route and create uncertainty for the economy and internal security. AP reported a similar warning from opponents, who said foreign workers support important sectors of the Swiss economy.

The result leaves the existing EU free-movement framework intact for now. AP reported that critics, including the federal government, Parliament and business groups, warned that the measure could damage Switzerland's relationship with the EU and reduce access to foreign workers. Politico Europe also reported that Swiss voters rejected the proposed population limit.
