Dispute Resolution Procedure
Summary: The Bilateral Agreements III introduce for the first time a parity-based arbitration tribunal for the resolution of disputes between Switzerland and the EU. The tribunal consists of three judges per side. For questions concerning EU law, it requests a preliminary ruling from the Court of Justice of the European Union (CJEU). This mechanism replaces the previous Joint Committees as the sole dispute resolution instrument.
¶ Political decisions: as of 6 September 2026
New political decisions checked on 6 September 2026; earlier background retains its stated reference date.
14.08.2026 — The Council of States Foreign Affairs Committee supported the three cohesion credits and the Federal Council’s wage-protection measures. It seeks stronger parliamentary information and consultation rights in dynamic legal alignment and dispute settlement. These are committee positions in ongoing proceedings. Original source.
04.09.2026 — The committee approved the stabilisation component by 9–3 with one abstention. It is ready for the Council of States’ autumn session; the electricity agreement is provisionally expected in winter. The committee supports the proposed immigration levy. This is not final parliamentary approval. Original source.
¶ The Problem: Previous Dispute Resolution
Previously, disputes over the interpretation or application of the bilateral agreements were handled in Joint Committees. These political bodies consist of representatives from both sides and decide by consensus. Where no agreement is reached, there is no binding mechanism for dispute resolution -- the issues in dispute remain unresolved [1][5].
This deficiency was a core element of the institutional gap that the Bilateral Agreements III are intended to close.
¶ The New Arbitration Tribunal
¶ Composition
The parity-based arbitration tribunal consists of six judges -- three per side [5][7]:
| Aspect | Details |
|---|---|
| CH judges | 3 (appointed by Switzerland) |
| EU judges | 3 (appointed by the EU) |
| Chair | Rotation or by agreement of the parties |
| Qualification | Independent legal experts |
| Decision | Binding on both sides |
¶ Procedural Sequence
¶ Step by Step
- Consultations: First, the parties attempt to find a solution in the Joint Committee (political level)
- Referral to the arbitration tribunal: If consultations fail, either side may refer the matter to the arbitration tribunal
- Examination of the legal question: The tribunal examines whether the dispute concerns a question of EU law
- CJEU preliminary ruling (if relevant): For EU law questions, the tribunal requests a preliminary ruling from the CJEU
- Decision: The arbitration tribunal renders a binding award
- Implementation: Both sides are obliged to implement the award [5][7]
¶ The Role of the CJEU
The role of the Court of Justice of the European Union (CJEU) in the dispute resolution procedure is the most politically contentious aspect of the Bilateral Agreements III [7][8].
¶ What the CJEU Does
The CJEU is called upon when a dispute concerns the interpretation of EU law. In this case, it issues a preliminary ruling that is binding on the arbitration tribunal regarding the EU law question [5].
Example: If Switzerland and the EU disagree about whether a particular Swiss wage protection mechanism is compatible with the free movement of persons, and this question concerns the interpretation of an EU directive, the arbitration tribunal requests the CJEU's opinion on the interpretation of that directive.
¶ What the CJEU Does Not Do
- The CJEU does not decide the dispute as a whole -- that remains the province of the arbitration tribunal
- The CJEU does not rule on the application of the law to the specific case
- The CJEU has no direct jurisdiction over Switzerland [5][7]
¶ Delimitation
| Function | CJEU | Arbitration Tribunal |
|---|---|---|
| Interpretation of EU law | Yes (binding) | No |
| Application to the case | No | Yes |
| Overall decision | No | Yes |
| Sanctions | No | Yes |
¶ Debate: "Foreign Judges"
¶ Supporters' Perspective
- The arbitration tribunal is parity-based (3+3) -- neither side has a majority of judges
- The CJEU interprets only EU law that Switzerland has voluntarily adopted
- A comparable mechanism exists in EFTA (EFTA Court with obligation to refer to the CJEU)
- The system creates legal certainty and predictability [5]
¶ Critics' Perspective
- The CJEU is an EU institution and therefore a partisan body -- "foreign judges" deciding on Swiss matters
- The binding effect of the CJEU preliminary ruling restricts the sovereignty of the arbitration tribunal
- There is a lack of reciprocity: no Swiss court decides on EU law questions in return [8][16]
An in-depth analysis can be found in the chapter Disadvantages: "Foreign Judges".
¶ Comparison with Other Models
| Model | Description | Application |
|---|---|---|
| Joint Committees | Political, consensus-based, no binding decision | Bilateral I/II (previous model) |
| EFTA Court | Own court of the EFTA states, follows CJEU case law | EEA/EFTA (Norway, Iceland, Liechtenstein) |
| Bilateral III | Parity-based arbitration tribunal + CJEU preliminary ruling | New model (from 2026) |
| EU accession | Direct jurisdiction of the CJEU | EU Member States |
