Summary: The Bilateral Agreements III introduce for the first time sectoral state aid rules in the areas of air and overland transport as well as electricity. Critics fear that these rules could restrict cantonal subsidy policy and impinge on Swiss federalism. Supporters emphasise that the rules are limited to three sectors and that no general EU state aid law applies.
EU state aid law generally prohibits state subsidies that distort competition in the single market. It regulates the conditions under which public funds may flow to companies [5][3].
Under the Bilateral Agreements III, sectoral state aid rules are introduced in three areas [5]:
The cantons have extensive competences in Switzerland in the area of economic promotion and subsidy policy. Critics argue [1]:
State aid rules were one of the three sticking points that led to the failure of the Framework Agreement (InstA) in May 2021. Switzerland feared that a general state aid law would restrict cantonal tax policy [5].
Supporters emphasise that the state aid rules are limited to three sectors and that no general EU state aid law applies [3][5]:
| Area | State aid rules | General EU state aid law |
|---|---|---|
| Air transport | Yes (sectoral) | No |
| Overland transport | Yes (sectoral) | No |
| Electricity | Yes (sectoral) | No |
| All other areas | No | No |
The sectoral state aid rules do not affect cantonal tax policy. They regulate exclusively direct state subsidies to companies in the three named sectors [3][5].
Compared to the failed InstA, Switzerland was able to significantly restrict the scope of the state aid rules. The InstA would have provided for comprehensive state aid law for all market access agreements [5].
The consultation (autumn 2025) brought specific concerns to light that go beyond general criticism.
Die Mitte (The Centre party) demands an independent authority for monitoring state aid rules and expresses concerns about the impact on cantonal state guarantees -- particularly those of the cantonal banks [11]. Since EU state aid rules restrict public subsidies that distort competition, the question arises whether the traditional state guarantee of cantonal banks could be classified as impermissible aid [11].
Supporters emphasise that the sectoral state aid rules are limited to air transport, land transport and electricity and do not affect the banking sector [3][5].
The Canton of Uri explicitly demands guarantees for water royalties and the right of reversion (Heimfall) in its consultation response [12]. Uri fears that EU state aid rules could in the long term be extended to hydropower, which would jeopardise the revenues of mountain cantons from hydropower exploitation [12].
The Federal Council has repeatedly clarified that the electricity agreement does not affect cantonal sovereignty over hydropower and that water royalty regulation remains a domestic matter [5].
A structural point of criticism concerns the voting procedure: the Bilateral Agreements III are subject to the optional referendum (simple popular majority), not the mandatory referendum (double majority of people and cantons) [5]. Critics, including several cantonal governments, argue:
Prof. Andreas Glaser (University of Zurich) has raised the question of whether the Bilateral Agreements III -- particularly the partial adoption of the UBRL with the right of permanent residence -- are compatible with Art. 121a para. 4 of the Federal Constitution, which stipulates that "no international treaties may be concluded that contradict this article" [13].
Supporters point out that the Federal Council has examined and confirmed constitutional compatibility, and that the existing procedure is standard for bilateral agreements [5].
