In late 2024, Switzerland and the EU concluded negotiations on a new comprehensive package of bilateral agreements (known as Bilaterals III). Ultimately, the fate of these accords will be decided by Swiss voters in a referendum

The package of bilateral agreements being finalised between Switzerland and the EU must be anchored in the Federal Constitution through a transitional provision, a parliamentary committee says.

The House of Representatives’ Committee of Political Institutions backs a proposal from a parallel Senate committee that calls for approval by a double majority of Swiss voters and cantons.
The lower chamber committee backed the proposal by 15 votes to 10, parliamentary services announced on Friday. Submitting the Swiss-EU agreement package to both voters and the cantons is “justified by its importance and constitutional nature”.
At the same time, the committee believes a simpler solution could be a “sui generis” one-of-a-kind referendum. By 16 votes to 9, it has asked for this option to be examined in greater detail.

A minority of parliamentarians opposes the proposal, arguing that a constitutional amendment would prevent the Swiss-EU agreements and their implementing legislation from being put to a single vote. This could jeopardise the overall compromise — for example on wage protection — and thus endanger Bilaterales III as a whole.
The proposal seeks to resolve uncertainties over the constitutionality of amending the Agreement on the Free Movement of Persons. According to the Senate committee, a contradiction exists between extending free movement and the constitutional provision on the autonomous management of immigration.

The new transitional provision would allow the approval of the agreement package despite constitutional rules limiting immigration. It would also settle the question of whether a double majority of the people and the cantons is required.
The proposal further stipulates that, in the event of a conflict between the agreements and either the Constitution or federal law, the Federal Court must apply Swiss law if the legislator has expressly rejected the agreements. This is intended to preserve sufficient national leeway to act accordingly and to accept the consequences under international law.
Views of legal scholars
The Senate committee heard from Stefan G. Schmid, professor of constitutional law at the University of St Gallen, at the end of March. He highlighted the constitutional tension created by extending free movement, which confers new residence rights.

While the Federal Council argued that the quantitative impact would be limited, Andreas Glaser, professor of public and administrative law at the University of Zurich, countered that the key issue is not the numbers but the legal ability to control them.
Schmid described a transitional provision as “legally feasible but politically difficult”.
