Ecuador’s Constitutional Court and the UAE BIT: From Conditional Acceptance to a Structural Test of ISDS

Key Takeaways

• Court approved Ecuador‑UAE BIT, but barred contractual ISDS claims
• Condition stems from Article 422 constitutional prohibition on ceding sovereign jurisdiction
• Decision revises Costa Rica precedent, yet leaves treaty amendment pending
• Ambiguity remains on distinction between contract and treaty disputes
• Restrictive ISDS scope may deter investors seeking full protection

Pulse Analysis

Ecuador’s constitutional architecture requires every international treaty to pass a three‑stage review, culminating in legislative ratification. Article 422 explicitly blocks any treaty that hands over sovereign jurisdiction to foreign arbitral tribunals for contractual or commercial disputes. After re‑joining the ICSID Convention in 2021, the government has been eager to revive ISDS mechanisms to lure investment, making the Ecuador‑UAE BIT a litmus test for how constitutional safeguards intersect with modern treaty‑based arbitration.

The Court’s March 30 opinion marks a departure from its 2023 Costa Rica ruling, where it excised ISDS provisions entirely. By allowing the BIT to proceed but mandating the exclusion of contractual disputes, the justices adopted a surgical approach that balances constitutional fidelity with investment promotion. Dissenting judges argued that treaty‑based arbitration does not equate to a loss of sovereignty, a view that aligns with Ecuador’s Organic Code on Production, Trade and Investment, which already endorses mandatory arbitration under UNCITRAL, ICC and CIAC rules. Yet the majority’s conditional acceptance leaves the treaty in limbo, as the government must rewrite the ISDS clause to satisfy the Court’s specifications.

For investors, the uncertainty surrounding the scope of ISDS in Ecuador creates a risk premium that could dampen capital inflows. While the conditional approval signals a willingness to engage with international dispute‑resolution mechanisms, the lack of a clear constitutional framework may prompt investors to seek jurisdictions with unequivocal ISDS protections. Policymakers will need to reconcile sovereign concerns with the competitive imperative of offering comprehensive arbitration safeguards, perhaps by codifying a nuanced interpretation of Article 422 that reflects contemporary international law. The outcome of the BIT’s amendment process will likely set a precedent for future treaties and shape Ecuador’s position in the regional investment landscape.
