If your company has investments, assets or contracts in Canada, or if you are a Canadian company operating in Spain, this interpretation changes the rules of the game in case of a dispute with the State. Interpretation No. 1/2026 of the CETA Joint Committee, adopted on March 5, 2026 and published in the EU Official Journal on July 3, 2026 with reference [2026/1469], establishes mandatory criteria for arbitrators resolving conflicts between investors and States under the EU-Canada Comprehensive Economic and Trade Agreement.
The result is a dual reading: greater legal certainty about which State conduct is claimable, but also possible restrictions on the scope of claims that investors can file in the future.
What does this regulation establish?
The CETA Joint Committee has issued a binding interpretation on four key elements of the treaty's investment protection chapter:
| Article / Annex | Subject matter | What the interpretation clarifies |
|---|---|---|
| Article 8.10 | Fair and equitable treatment | Establishes concrete criteria on what State conduct constitutes a violation of this standard and what falls within legitimate regulatory margin |
| Annex 8-A | Specific commitments on fair treatment | Delimits the scope of additional commitments assumed by the parties in relation to Article 8.10 |
| Article 8.9 | Expropriation | Clarifies when a State regulatory measure can be considered indirect expropriation that is claimable and when it is legitimate exercise of regulatory power in the public interest |
| Article 8.39 | Arbitral awards | Sets criteria on the content and limits of awards that CETA arbitral tribunals may issue |
The central element of this interpretation is the balance between investment protection and the right to regulate. States—both Spain and Canada—have margin to adopt measures of public interest (environmental, health, tax) without this automatically resulting in a winning arbitral claim by the affected investor. This interpretation binds arbitrators: they cannot ignore it when resolving disputes.
Economic and operational impact
The impact is not a direct tax or fine, but a change in the legal risk map for companies with bilateral Spain-Canada exposure:
- Future arbitral claims more limited: Investors planning to claim against the Canadian State (or Spanish State) under CETA will need to adjust their arguments to the new interpretive criteria. Some litigation strategies that could previously succeed now have weaker grounds.
- Greater predictability for investment planning: Knowing more precisely which State conduct is claimable allows better assessment of regulatory risk before investing.
- Review of contracts and dispute resolution clauses: Contracts that include references to dispute resolution mechanisms under CETA should be reviewed in light of the new criteria on fair treatment, expropriation and awards.
- Impact on ongoing litigation: Arbitral tribunals resolving active disputes under CETA are obligated to apply this interpretation, which may alter the outcome of pending cases.
Who does it affect?
- Spanish and European companies with direct investments in Canada (subsidiaries, joint ventures, productive assets)
- Canadian companies with investments in Spain or the EU
- Investors who have or foresee active or future arbitral disputes under CETA
- Law firms and legal advisors managing international investment arbitration litigation
- CFOs and risk directors of groups with bilateral Spain-Canada exposure who must assess regulatory risk in their investment models
- Companies in sectors with high regulatory exposure: energy, infrastructure, pharmaceutical, telecommunications and natural resources
Practical example
Imagine a Spanish energy company that holds an operating concession in Canada. The Canadian government approves new environmental regulations that restrict its activity and significantly reduce the value of the investment. Before this interpretation, the company could have argued before a CETA arbitral tribunal that this measure constitutes indirect expropriation (Article 8.9) or a violation of fair and equitable treatment (Article 8.10).
With Interpretation No. 1/2026 in force, the arbitral tribunal is obligated to apply the new binding criteria to determine whether that environmental measure falls within the State's legitimate regulatory margin or whether, on the contrary, it crosses the line into claimable expropriation. The outcome of the arbitration may differ from what would have been obtained under the previous interpretation. That is why reviewing the legal strategy before filing or continuing a claim is now essential.
What should companies do now?
- Identify exposure: Map whether your company has active investments in Canada or if you are a Canadian company with assets in Spain. If so, this interpretation directly affects you.
- Review ongoing litigation: If you have an active arbitral claim under CETA, consult with your legal advisor whether the new binding criteria of Article 8.10, Annex 8-A, Article 8.9 and Article 8.39 affect your procedural strategy.
- Audit contracts with CETA references: Review investment contracts, joint ventures or commercial agreements that include dispute resolution clauses under the CETA arbitration mechanism.
- Update regulatory risk analysis: Incorporate the new interpretive limits into risk valuation models for future investments in Canada or Canadian companies in the EU.
- Consult specialized international arbitration advice: This interpretation has complex technical effects. A specialist in investment arbitration can determine whether your position improves, worsens or remains the same under the new criteria.
Frequently asked questions
What is Interpretation No. 1/2026 of the CETA Joint Committee and why is it binding?
It is a decision adopted on March 5, 2026 by the CETA Joint Committee—the joint governing body of the EU and Canada of the treaty—that establishes mandatory criteria on how Articles 8.10 (fair and equitable treatment), Annex 8-A, Article 8.9 (expropriation) and Article 8.39 (arbitral awards) should be interpreted. Its binding nature means that arbitral tribunals resolving disputes under CETA cannot ignore it or depart from it.
Does this interpretation affect CETA arbitrations already underway?
Yes. The interpretation is mandatory for active arbitral tribunals, meaning it can alter the outcome of disputes already initiated. If you have an arbitral case in progress under CETA, it is urgent to review with your legal advisor whether the new criteria on fair treatment, expropriation and awards modify your procedural position.
Which Spanish companies should review their strategy following this interpretation?
Mainly Spanish and European companies with direct investments in Canada (subsidiaries, concessions, productive assets) and Canadian companies with investments in Spain. The sectors with the highest exposure are energy, infrastructure, pharmaceutical, telecommunications and natural resources, due to their high dependence on regulatory decisions by States.
Does the interpretation reduce investor protection against the State?
It does not necessarily eliminate it, but it does limit it. The interpretation balances investment protection with the right of States to regulate in the public interest. This means that some claims that could previously succeed—especially those based on environmental, health or tax measures by the State—now have a higher threshold to be considered expropriation or violation of fair and equitable treatment. In return, it provides greater legal certainty about which State conduct is indeed claimable.
When did this interpretation enter into force and where can I consult it?
