Summary: The more than 120 bilateral agreements between Switzerland and the EU have no common institutional umbrella. A uniform dispute resolution mechanism, dynamic legal alignment and independent oversight are all lacking. The attempt to close this gap with an Institutional Framework Agreement (InstA) failed on 26 May 2021.
The bilateral treaty architecture between Switzerland and the EU comprises over 120 agreements that were individually negotiated over decades. Each agreement has its own Joint Committee, its own rules and its own dynamic. What is missing is an overarching institutional framework [1].
Three central mechanisms that are standard in modern international relations are largely absent from the bilateral agreements:
In the event of disagreements over the interpretation or application of an agreement, there is no independent court and no arbitration procedure. Disputes are handled in Joint Committees -- parity-based political bodies in which both sides must find a consensual solution. If this fails, the dispute remains unresolved [1][2].
The agreements reflect the EU's legal status at the time of signature. When the EU develops its regulation further, the agreements become outdated. An adjustment requires formal negotiations and the agreement of both sides in the Joint Committees. In practice, this leads to a growing divergence in the legal foundations [1][3].
The only exception is the Schengen association: here, Switzerland must adopt developments in the Schengen acquis, otherwise the agreement faces termination [3].
There is no independent body that verifies whether Switzerland and the EU are correctly fulfilling their contractual obligations. Oversight lies with the contracting parties themselves -- a system that the EU increasingly regarded as inadequate [2].
To close the institutional gap, Switzerland and the EU began negotiations on an Institutional Framework Agreement (InstA) in 2014. This was intended to serve as an "umbrella" over the existing market access agreements for institutional rules. A negotiation result was available on 23 November 2018 [4].
The InstA draft envisaged:
The Federal Council identified three areas where "substantial differences" existed [4]:
| Sticking point | Problem |
|---|---|
| Wage protection | The EU demanded the adoption of the EU Posting of Workers Directive, which would have partially called into question Swiss flanking measures (8-day rule, deposit requirement). The trade unions rejected this. |
| Citizens' Rights Directive | The EU demanded the adoption of extended residence rights for EU citizens, which could have had implications for social welfare. |
| State aid | The EU wanted to introduce state aid rules that would have restricted cantonal sovereignty over subsidies and tax concessions. |
The consultation on the InstA (2019) produced mixed results. Business associations broadly supported the agreement, trade unions rejected it because of wage protection, and the SVP opposed it fundamentally as a "subjugation treaty" [4].
On 26 May 2021, the Federal Council informed the European Commission that it would not sign the institutional agreement. In its statement, it explained:
"The Federal Council is of the opinion that no solution could be found on the three remaining open points -- state aid, wage protection and the Citizens' Rights Directive." [4]
The termination triggered controversial reactions:
Supporters of the termination:
Critics of the termination:
The failure of the InstA had immediate consequences:
These consequences led to the erosion of the existing agreements, which increased the pressure for a new round of negotiations. In March 2022, exploratory talks began that ultimately led to the Bilateral Agreements III.
