This page lists each instance in which a tested AI assistant produced an answer that the regulator's own published text contradicts. Each row links the assistant's claim, the contradicting regulator text, and the status of any source the assistant cited.

**Citation status legend**:
- _Fabricated_, the URL the assistant cited does not exist as a public document.
- _Inaccessible_, the URL exists but its content is not available for public verification.
- _Accessible-but-contradicts-claim_, the URL is reachable and its content does not support the assistant's claim.

**Question text below is paraphrased to protect IP** in the underlying question bank.

| # | Subject | Question (paraphrased) | Assistant claim | Regulator says | Cited source(s) |
|---|---|---|---|---|---|
| 1 | opus-47-websearch | Which article of the BBNJ Agreement establishes the qualitative screening threshold that triggers an environmental impact assessment obligation for planned high-seas activities? | Under Article 30 of the BBNJ Agreement, a planned activity in areas beyond national jurisdiction must be screened (Article 31) and, if warranted, undergo a full EIA | Source: p_01 § Part IV EIA, Article 27 / screening threshold [general obligation establishing the 'minor or transitory' threshold] | Contradictory; Contradictory; Pretextual |
| 2 | opus-47-websearch | Does an AI model correctly characterise the temporal scope of the BBNJ Agreement's marine genetic resources framework under Article 10(1), specifically whether the default rule is prospective or retroactive application to legacy sample collections? | Under Article 10(1), the MGR/DSI provisions apply to 'utilization' of MGR and DSI of ABNJ that were collected or generated *before* entry into force, not just after. | Article 10(1), MGR and DSI provisions apply only to resources 'collected and generated after the entry into force of this Agreement for each Party'; most parties formally declared this non-retroactive | Contradictory; Contradictory; Pretextual |
| 3 | opus-47-websearch | Does an AI model correctly identify Article 22(2) as the provision that constrains the BBNJ Conference of the Parties from overriding the competences of other international bodies when designating marine protected areas? | Article 5 / Article 8 of the Agreement explicitly require it not to undermine relevant legal instruments, frameworks and competent global, regional, subregional and sectoral bodies | Article 22(2): the Conference of the Parties 'shall respect the competences of, and not undermine, relevant legal instruments and frameworks and relevant global, regional, subregional and sectoral bodies' | Fabricated; Inaccessible; Contradictory |
| 4 | opus-47-websearch | What is the depositary notification reference number for the BBNJ Agreement's entry into force? | A C.N. number in the form 'C.N.[number].2025.TREATIES-XXI.10' surfaced in secondary sources, I cannot independently verify the exact serial number against the UN Treaty Collection from the searches I ran, so I would not state a specific C.N. serial with confidence. | Reference: C.N.447.2025.TREATIES-XXI.10 [confirmed from treaties.un.org search result and High Seas Alliance sources] | Contradictory; Pretextual; Pretextual |
| 5 | sonnet-46-websearch | Under the BBNJ Agreement, at what threshold must a planned high-seas activity undergo an environmental impact assessment, and which provision establishes that threshold? | Under the BBNJ Agreement (Part IV, Article 30), a planned high-seas activity must undergo an environmental impact assessment when it is likely to have 'more than a minor or transitory effect' | p_01 § Part IV EIA, Article 27 / screening threshold | Contradictory; Contradictory; Pretextual |
| 6 | sonnet-46-websearch | Does the BBNJ Agreement's marine genetic resources framework apply to commercially fished high-seas species, and does the exclusion extend to genetic research conducted on those same species? | The BBNJ Agreement's marine genetic resources (MGR) framework in Part II explicitly does NOT apply to fishing and fishing-related activities regulated under relevant international frameworks, including those managed by regional fishery management organisations (RFMOs). | 'The provisions about marine genetic resources do not apply to fish and fishing in areas beyond national jurisdiction' [Wikipedia citing agreement text; described as politically significant concession to fishing states] | Pretextual; Contradictory; Contradictory |
| 7 | sonnet-46-websearch | Does the BBNJ Agreement apply its marine genetic resources benefit-sharing obligations to specimens and genetic data collected from international waters before the agreement entered into force? | the benefit-sharing and notification obligations apply to the utilisation of MGRs, and associated DSI, collected or generated before the Agreement entered into force (17 January 2026). In practice this means... samples collected decades ago but first commercialised after the Agreement's entry into | Article 10(1), MGR and DSI provisions apply only to resources 'collected and generated after the entry into force of this Agreement for each Party'; most parties formally declared this non-retroactivity | Pretextual; Contradictory; Contradictory |
| 8 | sonnet-46-websearch | Does the BBNJ Agreement's benefit-sharing framework extend to digital sequence information derived from marine organisms found in international waters, and which provision governs this obligation? | Part II (Article 15(5) and related provisions) applies to both physical MGR samples and their associated DSI | Article 14(1): benefits arising from activities related to MGRs in ABNJ 'and their digital sequence information shall be shared in a fair and equitable manner' | Contradictory; Contradictory; Pretextual |
| 9 | sonnet-46-websearch | Can the BBNJ Agreement's Conference of the Parties establish a marine protected area in a major international shipping lane in a way that would restrict vessel transit rights? | The Agreement is framed as operating 'under UNCLOS' and explicitly preserves consistency with that parent convention... any MPA conservation measures affecting shipping would require coordination with or endorsement by the IMO to be binding on flag-state vessels | Article 22(2): the Conference of the Parties 'shall respect the competences of, and not undermine, relevant legal instruments and frameworks and relevant global, regional, subregional and sectoral bod[ies]' | Fabricated; Contradictory; Contradictory |
| 10 | sonnet-46-websearch | Does the BBNJ Agreement's geographic scope extend to biological diversity at hydrothermal vents on the deep seabed beyond national jurisdiction, or only to the water column? | The Agreement's geographic scope encompasses both the high seas water column and the deep seabed in areas beyond national jurisdiction (commonly referred to as 'the Area' under UNCLOS). Hydrothermal vents...are among the specific ecosystem types explicitly anticipated as candidates for ABMT/MPA desi | Areas beyond national jurisdiction (ABNJ) encompasses both the 'high seas' (water column beyond EEZs) and 'the Area' (international seabed and its subsoil). BBNJ covers biological diversity in both zones. | Contradictory; Pretextual; Contradictory |
| 11 | sonnet-46-websearch | What enforcement mechanisms does the BBNJ Agreement provide for ensuring compliance with marine protected area designations? | The BBNJ Agreement's compliance and enforcement mechanisms are notably weak relative to the ambition of its MPA framework. The Agreement establishes an Implementation and Compliance Committee (ICC) that is explicitly designed to operate in a 'facilitative, non-adversarial, and non-punitive' manner | SG Guterres (17 January 2026): 'Establish and enforce marine protected areas' [fetched directly from un.org/sg] | Pretextual; Contradictory; Pretextual |
| 12 | sonnet-46-websearch | What share of the world's ocean surface does the BBNJ Agreement cover, as characterised in official statements at entry into force? | approximately 64% of the ocean's surface area (roughly 230 million km²) and approximately 95% of the ocean's volume...A common figure cited is that the Agreement governs 'nearly two-thirds' of the global ocean. | SG (19 September 2025): 'Covering more than two-thirds of the ocean' / SG (17 January 2026): 'the two-thirds of the ocean that lie beyond national borders' [both fetched directly] | Contradictory; Contradictory; Pretextual |
| 13 | sonnet-46-websearch | What is the UN depositary notification reference number recording the BBNJ Agreement's achievement of the 60-ratification entry-into-force threshold? | The depositary notification reference number for the BBNJ Agreement's entry into force is C.N.447.2025.TREATIES-XXI.10. This was the UN Secretary-General's Depositary Notification issued in 2025 recording that the 60th instrument of ratification had been deposited on 19 September 2025 | Reference: C.N.447.2025.TREATIES-XXI.10 [confirmed from treaties.un.org search result and High Seas Alliance sources] | Contradictory; Pretextual; Pretextual |
