Swiss voters reject proposal to restrict neutrality and sanctions

Swiss voters decisively rejected a proposal to write a more restrictive definition of neutrality into the constitution on Sunday, September 27. The federal result showed 70.2% voting against the Neutrality Initiative, leaving the government free to continue its current approach to international sanctions and security cooperation.

The initiative sought to define Switzerland as permanently armed and neutral, bar it from joining military or defence alliances, and limit cooperation with such alliances unless Switzerland itself was under attack or facing preparations for an attack. It would also have prevented Switzerland from adopting sanctions against states involved in a war, with exceptions for measures ordered by the United Nations and steps to prevent sanctions from being evaded through Swiss territory.

Supporters argued that a firm constitutional rule would better protect the country from being drawn into conflicts and preserve its role as a neutral mediator. Opponents, including the Federal Council and parliament, said the text would reduce Switzerland’s ability to respond to security crises and restrict the diplomatic and economic tools it has used in recent years.

Sanctions and the war in Ukraine

The immediate political backdrop was Switzerland’s decision to adopt many European Union sanctions against Russia after its full-scale invasion of Ukraine in 2022. The initiative would have sharply narrowed the circumstances in which Bern could independently impose sanctions on a party to a conflict. Switzerland’s government argued that such a prohibition would weaken its capacity to act alongside partners while maintaining its neutrality under international law.

Neutrality does not currently prevent the Swiss government from imposing economic sanctions. Bern distinguishes between military participation in a conflict and measures taken in response to violations of international law. The referendum tested whether that discretion should be curtailed by a binding constitutional provision.

The proposal also addressed cooperation with NATO. Switzerland is not a member of the alliance, but it participates in selected partnership activities and has sought closer practical cooperation as European security conditions have changed. The government warned that the initiative’s wording could complicate training, coordination and other defence arrangements even without formal alliance membership.

Government retains room to decide case by case

After the vote, Foreign Minister Ignazio Cassis said the result should not be interpreted as a rejection of neutrality itself. The government’s position is that Switzerland remains neutral while retaining the flexibility to decide how that principle applies to particular conflicts and international measures.

The ballot was a vote on the initiative’s constitutional text, not a referendum on joining NATO or abandoning armed neutrality. Switzerland’s Federal Department of Foreign Affairs describes neutrality as a long-standing element of the country’s foreign and security policy, with a legal core and political practice that has evolved over time.

The result leaves decisions about future sanctions and cooperation within the existing legal framework. It also means the government may continue to assess EU measures against Russia individually, including whether and how to adopt them in Swiss law, rather than facing the initiative’s broad constitutional ban.
