Swiss Federal Council Formally Submits 'Bilaterale III' Treaty Package to Parliament

The Swiss Federal Council officially approved and submitted a comprehensive treaty package to Parliament on Friday to deepen relations with the European Union. The agreement, known as Bilaterale III, marks a significant step in resolving years of diplomatic uncertainty between Bern and Brussels. Swiss President Guy Parmelin and European Commission President Ursula von der Leyen previously signed the package of agreements on March 2, 2026. The government characterized the deal as a strategic necessity for the nation's economic and political stability. This legislative move follows 12 years of complex negotiations aimed at modernizing the bilateral path. The draft law now moves to the Swiss Parliament for deliberation and a potential future referendum.

The treaty package has secured broad domestic backing from Swiss cantons and approximately three-quarters of political groups as of late 2025. However, the proposal faces scrutiny from some business sectors, including the economiesuisse federation, which has voiced specific criticisms. Ignazio Cassis, serving as Vice President and head of the Federal Department of Foreign Affairs in 2026, has been a central figure in steering the diplomatic process. The Federal Council emphasized that the agreement ensures Switzerland's participation in the EU internal market while preserving national sovereignty. Officials noted that the patience of the Europeans regarding the long-standing dossier has reached its limits. The package covers various sectors, including electricity, food safety, and health cooperation.

Switzerland and the European Union have managed their relationship through a series of bilateral agreements since the 1990s, following the Swiss rejection of European Economic Area membership in 1992. The first set of agreements, Bilaterals I, was signed in 1999, followed by Bilaterals II in 2004. Negotiations for a new framework began over a decade ago but faced a major setback in 2021 when Switzerland unilaterally walked away from talks on an Institutional Framework Agreement. The current Bilaterale III package represents a renewed effort to stabilize ties and update existing accords to reflect modern regulatory standards.

The government remains firm on the importance of the deal for the future of the Swiss Confederation. „The agreement is a strategic necessity for the country” — Swiss Federal Council via Bloomberg Business
