Swiss Voters Reject Stricter Neutrality Rules in Referendum

Swiss voters overwhelmingly rejected a proposal to impose stricter constitutional rules on the country’s long-standing neutrality, preserving Switzerland’s ability to adopt economic sanctions and cooperate with international security partners.

Official results from Switzerland’s Federal Statistical Office showed 70.15% voted against the Neutrality Initiative on September 27, while 29.85% supported it. The proposal was rejected by every canton, with voter turnout reaching 47.06%.

The initiative sought to formally establish a more restrictive interpretation of Swiss neutrality in the constitution. It would have prevented Switzerland from joining or cooperating with military and defence alliances unless the country faced an attack or preparations for one. It also would have barred sanctions against parties involved in wars unless those measures were approved by the United Nations.

Foreign Minister Ignazio Cassis stressed that the referendum concerned how neutrality should be implemented rather than whether Switzerland should remain neutral. The result allows Bern to maintain its existing approach, including cooperation with other countries on security and participation in sanctions regimes.

Switzerland largely adopted European Union sanctions against Russia following Moscow’s invasion of Ukraine, a decision that supporters of the initiative argued weakened the country’s traditional neutrality. The proposal was backed by figures from the right-wing Swiss People’s Party (SVP), while the Federal Council and Parliament opposed imposing more rigid constitutional restrictions.

Opponents argued that Switzerland needed flexibility to respond to international security developments while maintaining its neutral status. The government said the existing policy enables the country to safeguard its independence and security while cooperating internationally when necessary.

Switzerland’s neutrality has been enshrined in its Federal Constitution since 1848 and is internationally recognised. The government has maintained that neutrality remains central to Swiss foreign policy regardless of the referendum outcome.

With the initiative defeated, Switzerland retains its current framework for deciding on sanctions and security cooperation rather than adopting the proposed constitutional restrictions.
