Swiss Parliament Moves EU Deal Toward a Vote as Tuition-Fee Rules Face Scrutiny

Switzerland’s Senate has moved the EU package closer to a nationwide vote, while attaching a tougher approval route to the agreements. On October 1, 2026, senators rejected the Federal Council’s proposal for an optional referendum by 23 votes to 17, with 3 abstentions. That procedure would have required only a simple majority of voters. The chamber then backed a “sui generis” referendum, a route that would require approval from a majority of the cantons even without a constitutional amendment.

The decision places the package inside Switzerland’s most demanding democratic framework. A treaty can face a mandatory referendum in practice when lawmakers judge that it has a constitutional character, although the constitution does not explicitly require that step for this agreement. The Senate also approved a proposal from its Commission on Political Institutions to seek a double majority through a constitutional amendment.

The vote does not settle the matter. The House of Representatives must now examine the Senate’s proposals and revisit the Federal Council’s simple-majority option. Until that process ends, the exact ballot question and approval threshold remain unsettled.

A cantonal majority could determine whether the EU agreements survive the ballot box. Under the Senate-backed model, approval would require more than a national tally of voters. A majority of Switzerland’s cantons would also have to support the package, giving smaller cantons a decisive role alongside populous regions such as Zurich, Geneva and Vaud.

Swiss constitutional practice gives the cantons a direct voice on measures tied to the country’s federal structure. The Senate’s “sui generis” approach seeks that double legitimacy without formally changing the constitution. Its supporters argue that the agreements carry constitutional significance. The Federal Council had proposed a simpler route, requiring only a majority of people voting nationwide.

The distinction could shape the entire campaign. A package might win a national majority and still fail if enough cantons reject it. That makes the political geography of Switzerland central to the outcome, from urban centres with strong cross-border economic links to rural and peripheral cantons with different views of European integration. The House of Representatives will decide which of these competing procedures advances.

Lawmakers also want EU students at Switzerland’s two federal institutes of technology to face the same tuition fees as Swiss students. The decision covers EPFL in Lausanne and ETH Zurich, two institutions with major international research profiles and large communities of students from across Europe.

The measure emerged during parliamentary deliberations on the new package of agreements with the European Union. Deputies decided that EU students enrolled at the two institutions must receive equal treatment with Swiss students regarding tuition fees. The available source does not specify the current fee levels, the number of affected students or the timetable for implementation.

That limited provision carries practical importance. Tuition rules are a visible expression of how Switzerland translates its relationship with the EU into daily institutional policy. The debate reaches beyond treaty language and into access to higher education, university finances and the conditions offered to European students studying in Switzerland.

The decision is part of the broader parliamentary process and does not, on the information available, establish that the full EU package has been approved. The House of Representatives still has to continue its examination of the agreements and referendum procedure.

The procedural dispute has exposed a legal question with direct political consequences: who should approve the EU agreements, and by what majority? The Senate’s rejection of the optional referendum came by a margin of six votes, with three senators abstaining. It then endorsed the “sui generis” model by an almost identical margin, according to Swissinfo.

The two routes would produce different campaigns. A simple-majority referendum would be decided by the national popular vote. A mandatory-style vote involving the cantons would require the package to build support across Switzerland’s federal system. The Senate also backed a Commission on Political Institutions proposal designed to secure approval through a constitutional amendment and a double majority.

These choices matter because the agreements will be judged twice: first through parliamentary handling of the treaty and referendum question, then through the institutional rules governing the public vote. The Federal Council’s preferred option remains alive because the House of Representatives must consider it again. Parliament therefore still has to settle both the substance of the package and the democratic threshold attached to it.

The next decision belongs to the House of Representatives, where the Senate’s competing proposals will face another test. Deputies will consider the Senate-backed “sui generis” referendum, the constitutional-amendment proposal seeking a double majority and the Federal Council’s option for a simple national majority. The chamber’s response will determine how the EU package proceeds through the federal institutions.

For voters, the process has two immediate consequences. First, the package is moving toward a public decision rather than remaining solely a parliamentary matter. Second, the eventual ballot may ask for approval from both the people and the cantons, depending on the outcome in the House. The Senate has made clear that it regards the agreements as significant enough to warrant a broad federal mandate.

The tuition provision adds a domestic policy dimension to the debate. Equal fees for EU students at EPFL and ETH Zurich would connect the European agreements with the operation of Switzerland’s flagship technical universities. Parliament’s next stage will show whether that provision remains intact and how lawmakers define the package voters may ultimately receive.
