Swiss voters have rejected a proposal that would have introduced a stricter definition of the country’s traditional policy of neutrality into the Constitution.
In the referendum held on September 27, 2026, the proposal was rejected by 70.15% of voters, while 29.85% voted in favour. All 26 cantons also rejected the initiative, meaning it failed to achieve the required double majority of voters and cantons.
The initiative, known as the “Safeguard Swiss Neutrality” proposal, sought to define Switzerland’s neutrality as “perpetual and armed”. It would have placed additional constitutional limits on the country’s ability to join military alliances, participate in conflicts abroad and impose certain sanctions against countries involved in wars.
Supporters of the proposal argued that Switzerland’s neutrality has helped keep the country away from wars and allowed it to act as a mediator in international disputes. The campaign was backed mainly by the right-wing Swiss People’s Party and the Pro Schweiz movement.
The proposal also sought to restrict Switzerland from imposing economic or diplomatic sanctions against countries involved in conflicts unless they were required by the United Nations. This issue became particularly important after Switzerland adopted many European Union sanctions against Russia following Russia’s invasion of Ukraine in 2022.
Supporters argued that a stricter interpretation of neutrality would protect Switzerland’s independence and preserve its traditional role as an impartial country. They also expressed concern that closer military cooperation with organisations such as NATO could weaken Switzerland’s neutral position.
The Swiss government and most political parties opposed the initiative. They argued that the existing system gives the government enough flexibility to respond to changing international security conditions while maintaining Switzerland’s neutral status.
Government officials also warned that restricting military cooperation could make it more difficult for Switzerland to work with neighbouring countries and other European partners on security issues. The government maintained that Switzerland can remain neutral while cooperating with other countries to strengthen its security.
The referendum result means that Switzerland’s current approach to neutrality remains in place. Neutrality has been included in the Swiss Federal Constitution since 1848 and is recognised under international law. The government can continue to participate in sanctions regimes while maintaining its neutral status.
The debate over neutrality, however, is not expected to disappear. Switzerland continues to face questions about how a neutral country should respond to wars and security threats in Europe while maintaining its diplomatic role.
The referendum has therefore settled the immediate constitutional proposal, but discussions about the balance between neutrality, sanctions, international cooperation and national security are likely to continue in Switzerland.
