NextFin News - A high-stakes legislative review in Bern has concluded that Switzerland’s landmark "Bilaterals III" package with the European Union cannot proceed without a formal amendment to the national constitution. Lawmakers in the Swiss capital signaled on Wednesday that the scope of the agreement—which includes dynamic alignment with EU law and new dispute resolution mechanisms—triggers a mandatory constitutional referendum, significantly raising the bar for the deal’s ultimate survival.
The determination by parliamentary committees follows the Federal Council’s March 13 dispatch of the package, which seeks to stabilize relations with Switzerland’s largest trading partner. According to Bloomberg, the legal consensus emerging in Bern suggests that because the deal touches upon fundamental sovereign powers, particularly regarding state aid monitoring and the role of the European Court of Justice in arbitration, it must be put to a "double majority" vote. This requires approval not only from a majority of the national popular vote but also from a majority of Switzerland’s 26 cantons, a hurdle that has historically derailed ambitious foreign policy initiatives.
The "Bilaterals III" package is the culmination of years of stop-and-start negotiations aimed at modernizing the 1999 and 2004 agreements. It introduces new sectoral frameworks for electricity, food safety, and health, while updating the Free Movement of Persons agreement. However, the inclusion of "dynamic alignment"—a requirement for Switzerland to adopt relevant EU legislative changes automatically—has long been a flashpoint for the Swiss right. By classifying the deal as a constitutional matter rather than a standard legislative treaty, lawmakers have effectively handed a powerful veto to the smaller, more conservative rural cantons.
The Swiss government, led by the Federal Council, has consistently framed the deal as a "strategic necessity" for economic stability. In its April 22 adoption of the package, the Council emphasized that the bilateral approach remains the only viable path to maintain access to the EU single market. To mitigate domestic opposition, the government recently reached an agreement with the cantons to ensure their involvement in "decision-shaping" and dispute settlement. Yet, the legal requirement for a constitutional change suggests these concessions may not be enough to bypass a grueling national campaign.
The political risk is compounded by the current composition of the Swiss parliament and the influence of the Swiss People’s Party (SVP), which has long campaigned against "foreign judges" and the erosion of Swiss neutrality. While pro-business groups and the pharmaceutical sector—heavily dependent on EU market access—argue that failure to ratify the deal would lead to a slow "erosion" of Swiss prosperity, the constitutional requirement forces a binary choice on the electorate that transcends simple economic calculus.
If the lawmakers' assessment holds, the timeline for ratification will likely stretch into late 2026 or 2027. The Federal Council had originally proposed an optional treaty referendum, which only requires a simple popular majority. Shifting to a mandatory constitutional referendum changes the math entirely. Historically, several Swiss initiatives have won the popular vote but failed the cantonal majority, a scenario that now looms over the most significant diplomatic effort between Bern and Brussels in two decades.
