I was reading 18 articles. Two authentic texts (English and French) codrafted simultaneously, each shaped by its own legal tradition, each equally binding. I read the French, then I read the English and I realized they were not saying the same thing.
Not because anyone made a mistake. Because two legal traditions, working on the same instrument at the same time, made different choices about what needs to be said explicitly, and those choices reveal what each tradition considers ambiguous or legally perilous in the other’s formulation.
The International Law Commission’s Draft Articles on the Protection of Persons in the Event of Disasters — the foundation of what will become a binding treaty by 2027 — exist in six official UN languages, all equally authentic. But the deepest jurisprudential tension lives between two: the English, shaped by common law flexibility and diplomatic generalism, and the French, forged in the codifying logic of the civil law tradition.
Read the English first, and you see a humanitarian framework. Read the French first, like me, reading the PPED backwards, and you see a second legal architecture underneath, one that resolves ambiguities the English-language drafting left open. Below I explain what it says to me.
The sovereignty firewall we don’t talk about
Start with Article 3(b). The English defines the “affected State,” a term so natural, so intuitive, that no English-speaking diplomat would pause over it. But the Francophone co-drafters did pause. They rejected État affecté and chose État touché instead. This is a sovereignty firewall.
In French international legal discourse, État affecté is a term of art anchored in transboundary environmental law. Born from the legacy of the Trail Smelter arbitration, the phrase crystallized in subsequent OECD recommendations and International Law Commission drafts on cross-border pollution, a dense legal architecture defining the downstream fallout of a neighbor’s hazardous activities.
Francophone diplomats hear État affecté and immediately picture a toxic plume crossing a border. It signals the secondary casualty of a foreign hazard. To use État affecté in the PPED would have implied that a disaster’s legal gravity depends on cross-border impact, opening the door to interventionist interpretations where neighboring states claim standing based on being secondarily “affected.”
État touché closes that door. It denotes direct, physical, catastrophic impact on a state’s own territory. The disaster happened here, to us, and the sovereign response begins here.
The English didn’t need to make this distinction. The French did, because in the civil law tradition, a term of art carries its entire jurisprudential history into every new instrument where it appears. Choosing touché over affecté was a preemptive act of legal boundary-setting.
Splitting “duty” in two
The English text uses the word “duty” twice in quick succession.
Article 10: the affected State has the “duty to ensure” protection of persons on its territory.
Article 11: when a disaster exceeds national capacity, the affected State has the “duty to seek” external assistance. Same word. Same grammatical weight. A reader of the English might assume these are two expressions of the same kind of obligation.
The French text says otherwise.
Article 10 renders “duty” as devoir: l’État touché a le devoir d’assurer la protection des personnes.
Article 11 renders “duty” as obligation: l’État touché a l’obligation de rechercher l’assistance. In French legal architecture, these are not synonyms.
A devoir is a sovereign, philosophical imperative: the State protects its people because protecting them is what statehood means. An obligation is an enforceable legal bond owed to the international community, a vinculum juris with consequences for non-compliance.
The English text treats both duties as functionally equivalent. The French text establishes a hierarchy: Article 10 is about the social contract between a state and its citizens. Article 11 is about the legal contract between a state and the international order. A state that fails in its devoir fails its own people. A state that fails in its obligation breaches international law.
This distinction is invisible in the English version. It is structural in the French. And neither text is wrong, they simply reveal different assumptions about what the word “duty” contains.
prohibition becomes an impossibility
Article 13(2) may be the most consequential sentence in the entire instrument. The English states: “Consent to external assistance shall not be withheld arbitrarily.” Standard prohibitive language. Shall not: the workhorse of international treaty drafting, carrying the weight of mandatory prohibition.
The French text reads: Le consentement à l’assistance extérieure ne saurait être refusé arbitrairement.
Ne saurait. Not ne doit pas (must not). Not ne sera pas (will not). The conditional form of savoir (to know, to be capable of) expressing not a prohibition but a moral impossibility. A state cannot arbitrarily refuse consent in the way that a circle cannot be square. Arbitrarily withholding life-saving assistance contradicts the very rational justification of sovereign statehood. It cancels the State.
This is not a higher degree of the same obligation. It is a different category of normative statement. The English tells a State what it must not do. The French strips the State of the capacity to do it.
Three lines later, in Article 13(3), when the text requires the affected State to communicate its decision in a timely manner, the French snaps back to the mandatory doit (must). The contrast is deliberate: logistical communication is a procedural mandate. The refusal of life-saving aid is a philosophical impossibility. The English flattens both into shall.
timeline Collapsed in English
One more. Article 2, the object clause. The English speaks of facilitating “response to disasters.” A word so broad, so functionally neutral in English, that no one questions its temporal scope.
But when the ILC’s Francophone members co-drafted the French text, they had to choose, because French forces the choice. In earlier ILC sessions, the Commission used réaction rather than réponse: a term deliberately selected to encompass the full crisis lifecycle, from structural prevention through post-disaster recovery, not merely the logistical deployment phase that réponse implies. The ILC commentaries make the reasoning explicit: réponse was deemed too narrow, too reactive, too bound to the post-event timeline.
The final 2016 text settled on réponse in Article 2 while retaining the active participle réagissant in Article 6 (en réagissant aux catastrophes, literally “in reacting to disasters”), preserving the continuous, lifecycle-spanning quality the drafters fought for. The debate across multiple ILC sessions tells us something important: “response” in English carries no inherent temporal limitation, so no one needed to argue about it. In French, the Francophone drafters did argue because the language forced a conceptual choice the English never had to make.
What reading backwards teaches
None of these divergences appear in the ILC commentaries as drafting disputes. They are not flagged as inconsistencies or explained as compromises. And that is precisely the point.
The French text does not translate the English. It was never meant to. Both are authentic. Both bind. But the civil law tradition that shaped the French formulation demands a kind of precision that the common law tradition shaping the English does not require. Every lexical choice in the French resolves an ambiguity that the English leaves open. The English drafters were not careless. English simply permits ambiguity in places where French demands specification.
For the institutions that will implement this treaty (IFRC, ICRC, UNHCR, UNOCHA, and the national disaster management authorities of 193 member States) the distinctions will be real. When the consolidated negotiation text emerges from the April 2026 Working Group, and when the anticipated diplomatic conference convenes in Manila in early 2027, the words that survive will carry legal force in every language simultaneously.
The PPED is not one text in two languages. It is two legal instruments that must agree. And right now, in the places that matter most, they are saying different things.
