Introduction
On 30 March 2026, Ecuador’s Constitutional Court docket issued Dictamen 19-25-TI/26A, conditionally approving the Settlement for the Promotion and Safety of Investments between Ecuador and the United Arab Emirates (the “UAE BIT”), together with the investor-State dispute settlement (“ISDS”) mechanism established in Article 20. The ruling concludes a two-stage constitutional overview: on 5 March 2026, the Court docket decided that the UAE BIT required full constitutional overview underneath Article 419 of Ecuador’s 2008 Structure; the 30 March ruling delivered that overview. Legislative approval by the Nationwide Meeting stays a situation of ratification—anticipated to comply with, given the ruling social gathering’s majority—after the amended textual content is re-submitted to the Court docket for verification.
The central query put to the Court docket was slim: does Article 422 of Ecuador’s Structure prohibit funding treaties containing worldwide arbitration or ISDS clauses? Article 422 offers, in its related half, that Ecuador “shall not conclude treaties or worldwide devices during which the State cedes sovereign jurisdiction to worldwide arbitral our bodies in disputes of a contractual or industrial nature between the State and pure or authorized individuals.” By seven votes to 2, the Court docket held that Article 422 doesn’t prohibit treaty-based worldwide arbitration of funding disputes, supplied that Article 20 of the UAE BIT be amended to expressly exclude from such arbitration any disputes of a contractual or industrial nature between Ecuador and personal individuals, and that the amended textual content be verified by the Court docket earlier than ratification.
In substance, the ruling opens the constitutional door to funding treaty-based ISDS for the primary time since 2008, reversing the place of Ecuador’s Constituent Meeting, the Court docket’s personal 2023 jurisprudence, and two latest referendums rejecting constitutional change to that impact. This publish argues that the holding is analytically unsound on the phrases of the ruling itself, and that its implications attain nicely past Ecuador.
Article 422: context and goal
Article 422 was written by Ecuador’s 2007–2008 Constituent Meeting in response to the nation’s expertise as a serial ISDS respondent. By 2008, Ecuador confronted a minimum of 13 such claims. In Occidental v. Ecuador (LCIA, 2004), a contractual VAT dispute was transmuted right into a treaty declare; Ecuador’s defence that the matter belonged earlier than home courts was rejected by the tribunal, and the nation paid USD 71.5 million in damages. EnCana v. Ecuador (LCIA, 2006) arose from the identical VAT scheme and reached the other consequence—confirming that the boundary between a contractual and treaty dispute was set not by treaty textual content however by tribunal discretion. By the point the Constituent Meeting convened, Occidental v. Ecuador (II)—initiated in 2006 by the identical claimant looking for billions after Ecuador terminated an oil concession—was already pending.
Article 422 was a direct constitutional response to this expertise. The drafters’ purpose was to ban treaties that “switch jurisdiction in disputes arising from contractual or industrial relationships with transnational companies to supranational arbitral our bodies” (see para 167 of Dictamen 2-23-TI/23). Ecuador subsequently terminated its BIT community, and in 2023 the Court docket reaffirmed the prohibition, hanging down ISDS provisions in a proposed settlement with Costa Rica.
The primary floor: whether or not funding disputes are “contractual or industrial” in nature
The bulk holds that disputes underneath Article 20 of the UAE BIT don’t fall inside Article 422’s prohibition on submitting ‘controversias contractuales o de índole comercial’ to worldwide arbitration as a result of, as soon as characterised as funding‑treaty claims, they’re now not handled as contractual or industrial disputes lined by the clause. It invokes the ‘treaty/contract distinction’—the concept a declare grounded in a treaty’s funding protections is legally separate from a contractual declare, even when each come up from the identical details—citing Christoph Schreuer’s commentary and the Vivendi v. Argentina annulment committee (2002), and treats this distinction as settled funding arbitration regulation that the Constituent Meeting should have had in thoughts.
This characterisation is traditionally inaccurate. On the time of the Constituent Meeting’s deliberations, the treaty/contract distinction was among the many most contested questions in ISDS jurisprudence. Vivendi v. Argentina (ICSID Annulment, 2002) and the SGS v. Pakistan (ICSID, 2003) and SGS v. Philippines (ICSID, 2004) selections produced contradictory outcomes on materially related details, exactly on whether or not a contractual dispute may additionally represent a treaty violation. As Schreuer himself later acknowledged in a 2014 article, tribunals with broadly-worded clauses are “authorised” to think about claims past the treaty—a alternative open to tribunals, not a set rule. Studying that unsettled debate again right into a 2008 textual content drafted in response to ISDS follow, not doctrinal taxonomy, is anachronistic. The Meeting data draw no such distinction.
There’s a additional issue. The UAE BIT’s Article 1 defines “funding” to incorporate “rights arising from a contract, together with turnkey, development and administration contracts” and “concessions … conferred by regulation or underneath contracts.” For the subset of investments expressly outlined as contract-derived rights or concessions, the treaty/contract distinction collapses underneath the treaty’s personal definition: the identical contractual association is concurrently a controversia contractual for Article 422 functions and an “funding” for Article 20’s jurisdiction over “any dispute regarding an funding.” The bulk constrains Article 422 to contractual disputes whereas approving jurisdiction over funding disputes—with out participating with the truth that the treaty itself re-characterises sure contractual rights as investments.
The bulk’s remedy of the de índole comercial limb of Article 422 of the Structure is equally poor. That phrase—“of a industrial character”—factors to the substance of a dispute, not its formal label. This studying tracks each the strange which means of the Spanish (índole denotes nature or character) and the aim of Article 422, which was drafted exactly to foreclose the sort of tribunal-led re-characterisation on show in Occidental and EnCana. Ecuador’s Industrial Code defines industrial acts as routine actions of manufacturing, trade of products, or provision of companies carried out with an financial goal. The argument is that this: no matter how the treaty labels the dispute, any exercise protected underneath the UAE BIT will qualify as “industrial exercise” underneath Ecuadorian regulation—as a result of “funding” underneath the BIT presupposes an financial contribution, a industrial presence, or routine financial exercise of the type the Industrial Code describes. It follows that each dispute arising from an Article 20 funding is, in its substance, a dispute “of a industrial character” for Article 422 functions, no matter its formal pleading.
The bulk’s personal reasoning confirms this. Addressing the UAE BIT’s denial-of-benefits clause, the bulk notes that the treaty might deny safety to enterprises missing “substantive industrial actions” in a Celebration’s territory (at para 131). That by itself doesn’t decide the authorized character of the reason for motion—pleaded as a treaty breach—however Article 422 speaks to the character of the controversy, not its formal pleading. A dispute whose complete factual and financial predicate is the operation of a industrial enterprise, whose damages measure hurt to that enterprise, and whose admissibility activates the claimant’s industrial exercise, is substantively industrial—exactly the controversias de índole comercial that Article 422 was designed to maintain out. The bulk doesn’t tackle this contradiction.
The bulk’s interpretation additionally founders on the textual content of Article 422 of the Structure itself. The supply opens by prohibiting Ecuador from concluding “treaties or worldwide devices” that cede sovereign jurisdiction in disputes of a contractual or industrial nature. Article 422 is, by its personal phrases, a prohibition on what treaties might do. On the bulk’s studying—that any dispute arising from a treaty is “treaty-based” and due to this fact exterior the prohibition of Article 422—the availability empties itself: each instrument it regulates (a treaty) would, on that logic, be excluded from its attain. The drafters can’t have meant a prohibition that prohibits nothing.
One would possibly defend the bulk’s studying extra narrowly—limiting Article 422 to treaties that instantly submit contractual disputes to arbitration. However fashionable BITs, together with this one, don’t submit “contractual disputes” to arbitration as such; they submit “funding disputes,” into which contractual rights are definitionally absorbed. On that narrower studying, Article 422 would prohibit a treaty type that doesn’t exist in follow. Lastly, “worldwide devices,” as used alongside “treaties,” refers to agreements between States ruled by worldwide regulation, not contractual preparations with personal individuals—a studying confirmed by Article 422’s placement underneath the constitutional heading “Worldwide Relations.”
The 2023 Court docket resolved the equal query in the wrong way. In Dictamen 2-23-TI/23—authored by Choose Herrería Bonnet, now Authorized Secretary to President Noboa—the Court docket reviewed the Constituent Meeting document intimately, rejected the treaty/contract distinction as inapplicable, and declared the ISDS provisions of the Costa Rica settlement unconstitutional. The 2026 majority’s departure is effected in a single sentence: its evaluation “expressly departs from” the prior ruling as a result of the 2023 Court docket “didn’t think about the excellence, recognised in worldwide funding regulation, between contractual claims and treaty-based claims.” However the 2023 Court docket did think about that distinction and rejected it.
The bulk’s personal conditional approval reinforces the purpose. Having held that treaty-based funding disputes fall exterior Article 422’s prohibition, the Court docket nonetheless required—as a situation of constitutionality—that Article 20 of the UAE BIT be amended to expressly exclude from worldwide arbitration any disputes of a contractual or industrial nature between Ecuador and personal individuals. One would possibly defend the carve-out as a supplementary textual safeguard, making certain the treaty mirrors a distinction the Structure already attracts. However the majority’s personal reasoning forecloses that protection: it treats the treaty/contract distinction as inherent and automated, not as a distinction requiring textual reinforcement. If the excellence is self-operative, the carve-out is redundant; if it’s not, the bulk’s reasoning collapses. Both means, the carve-out concedes what the evaluation denies: the boundary between treaty claims and contractual or industrial claims shouldn’t be self-executing. As Justice Lozada Prado notes in dissent, it is going to in the end fall to the arbitral tribunal to find out whether or not a given dispute falls inside or exterior the carve-out—giving rise to precisely the Kompetenz-Kompetenz downside Article 422 was designed to foreclose.
The second floor: whether or not ISDS constitutes a “cession of sovereign jurisdiction”
The bulk’s second floor holds that funding arbitration doesn’t “cede sovereign jurisdiction” as a result of the tribunal’s mandate is proscribed to figuring out Ecuador’s worldwide duty—a operate carried out on the airplane of worldwide regulation relatively than home regulation. This drains Article 422’s operative time period of sensible content material. The related constitutional query is a purposeful one: is a home courtroom displaced as the first adjudicator of disputes to which the State is a celebration? On the phrases of Article 20 itself, the reply is clearly sure. Below Article 20, a overseas investor might provoke binding arbitration with out exhausting home treatments, receive an award enforceable in opposition to Ecuador’s sovereign belongings, and completely foreclose Ecuador’s courts from the identical dispute—some extent the bulk itself acknowledges, noting that “the selection of discussion board is remaining.”
The 2023 ruling was specific: underneath ISDS, “the State wouldn’t have the ability to guage or implement judgments,” whereas the investor may “with out exhausting home treatments” go instantly “to a global arbitration establishment.” Accordingly, this could “suggest that the State submits to being judged by these establishments, … thus transferring their jurisdiction” (para 176). The 2026 majority doesn’t have interaction with that evaluation; it relabels the identical institutional displacement to disclaim that it happens.
The inconsistency reaches past Ecuador’s home constitutional order. Within the ISDS case, Merck v. Ecuador (PCA Case No. 2012-10), Ecuador’s personal counsel argued earlier than an arbitral tribunal that “the correct of a overseas investor to invoke worldwide arbitration instantly in opposition to a sovereign State is a unprecedented concession of sovereignty and an exception to the overall unavailability of obligatory dispute decision procedures on the worldwide stage” (para 83). That characterisation displays a place many States and students share: ISDS as a departure from the default guidelines of sovereign immunity and jurisdiction. The 2026 majority doesn’t clarify why Ecuador’s prior characterisation of ISDS—superior earlier than a global discussion board—needs to be disregarded when deciphering a constitutional provision whose drafters shared the identical understanding.
Democratic rejection and institutional stress
The ruling can be in pressure with direct democratic expressions of constitutional choice. In April 2024, following a petition by President Noboa, voters had been requested whether or not Ecuador ought to amend Article 422 to allow worldwide arbitration as a way of resolving funding, contractual, and industrial disputes. 65% voted no. In November 2025, 62% rejected a constituent meeting course of understood as an extra automobile for a similar goal. If Article 422 already permitted treaty-based worldwide arbitration to resolve overseas funding disputes, no referendum would have been wanted. The Government’s pursuit of a constitutional modification (and presumably, the Court docket’s acceptance of the proposition) is essentially the most direct accessible proof that Article 422 was understood, even by its most motivated opponents, as an operative constraint.
These democratic rejections didn’t happen in isolation. In August 2025, the UN Particular Rapporteur on the Independence of Judges and Legal professionals issued an pressing enchantment expressing deep concern over “threats, intimidation and political stress by high-level public officers” in opposition to the Court docket. On 31 March 2026—the day after the ruling—the Court docket itself warned publicly that it was working underneath “sustained institutional pressures.” Enrique Herrería Bonnet—creator of the 2023 ruling this majority reverses, now Authorized Secretary to President Noboa—publicly criticised the Court docket’s preliminary dealing with of the UAE BIT overview and acknowledged speaking with sitting justices whereas the case was pending. Subsequently, the Prosecutor’s Workplace opened an investigation into Justice Lozada Prado (one of many two dissenters)—and eight days after the ruling, Justice Raúl Llasag (the opposite dissenter) resigned from the Court docket. These details don’t, by themselves, set up improper affect. However they bear on whether or not this ruling may be learn as an unbiased, principled act of constitutional interpretation—versus an institutional output formed by the stress its authors themselves have publicly described.
Implications for the worldwide funding regulation debate
Ecuador’s ruling doesn’t come up in a vacuum in worldwide regulation. As I’ve argued in an earlier publish for EJIL:Speak!, ISDS is at a second of accelerating contestation: the European Union and the vast majority of its Member States have withdrawn from the Power Constitution Treaty; Bolivia, India, Indonesia, and South Africa have denounced most of their funding treaties; and Canada and the US eliminated ISDS from the renegotiated NAFTA. In the meantime, ISDS reform negotiations proceed at UNCITRAL Working Group III and underneath the OECD programme on Modernising Funding Treaties. Extra not too long ago, Colombia has emerged as among the many most vocal critics, with civil society and authorities voices pushing to exit the system—a trajectory sharpened by the Santa Marta Transitioning Away from Fossil Gasoline Convention, which has positioned State regulatory obligations and the chilling impact of ISDS publicity on these obligations on the centre of its agenda.
Towards this backdrop, Ecuador’s ruling represents a step in the wrong way, by means of a course of whose institutional integrity has been publicly questioned. Its holdings are framed as basic interpretations of Article 422—not UAE BIT-specific rulings—and can accordingly govern constitutional overview of any future ISDS-containing treaty submitted to the Court docket. The possible attain is appreciable: the pending Canada–Ecuador FTA, which incorporates an ISDS mechanism, now has a transparent constitutional pathway.
The ruling illustrates a sample seen past Ecuador: the place democratic majorities and constitutional courts as soon as closed the door to ISDS, government stress and judicial reconfiguration can and are reopening it. In Ecuador’s case, the consequence reverses greater than a decade of jurisprudence, two referendums, and the nation’s personal prior authorized positions—with out the standard of reasoning these prior commitments demanded. The query shouldn’t be solely whether or not the bulk was proper on the regulation; it’s what it means for the reform agenda when a constitutional prohibition, constructed by democratic mandate and confirmed by well-liked vote, may be reversed by a reconfigured courtroom underneath government stress—and what mechanisms of worldwide and comparative scrutiny stay accessible when it does.
