Standard / soft law

High-impact AI should undergo an ethical impact assessment with oversight (UNESCO)

UNESCO Recommendation on the Ethics of AI (2021), para. 50 (Ethical Impact Assessment) · official text · Soft law or guidance (not binding law)

Per the UNESCO Recommendation on the Ethics of AI (paras. 50 and 53), Member States should introduce ethical impact assessment (EIA) frameworks to identify and assess the benefits, concerns, and risks of AI systems and appropriate prevention/mitigation/monitoring measures, and adopt procedures — particularly for public authorities — to predict consequences, mitigate risks, and establish oversight mechanisms (auditability, traceability, explainability, external review), with assessments transparent and open to the public where appropriate. Detect a high-impact AI deployment with no ethical/impact-assessment artifact or oversight provisions.

Who it applies to

Duty falls on: developer, deployer
Systems covered: high risk, automated decision
AI actors and Member States (especially public authorities) deploying AI that may significantly affect people. Voluntary UNESCO recommendation; applied by 194 Member States. UNESCO provides an EIA methodology + Readiness Assessment.

The guard to add

Organizational artifact to keep (not verifiable from code); the guard is the record, its owner and its upkeep.

Complete an impact assessment of a high-impact AI deployment's benefits, risks to affected people, mitigations, and oversight before first use, and keep it current.

A deployment-level assessment owned by the deploying business owner with legal and ethics input: how and where the system is used, who is affected and which groups are most exposed, benefits and specific risks of harm, mitigations and what happens if a risk materialises, and oversight provisions (decision logs for traceability, explanations, human oversight, complaint handling, external review). It is completed before first use, updated when any of those elements change, and published or shared with reviewers where appropriate. The deploy pipeline can check that a current, signed assessment exists for each high-impact deployment.

Where it goes: 12 repository artifacts, 15 agent action surface.

Example (Deployment impact assessment (docs/impact/)), before:

# Benefits eligibility assistant
DPIA done in 2024.

After:

# Impact assessment: benefits eligibility assistant (2026-07-15)
- Use: caseworkers see an AI eligibility recommendation; weekly batch + on demand
- Affected: applicants; most exposed: non-native speakers, people with irregular income
- Risks: wrongful denial, delayed payment, opaque reasons
- Oversight: caseworker decides; every recommendation logged with model version and reasons
- If harm occurs: pause switch, re-review affected cases, complaint route via /appeals
- External review: annual review by independent auditor; DPIA cross-referenced
- Sign-off: service owner, DPO (2026-07-20)

Control: High-impact AI deployed without an ethical/impact assessment. The same guard addresses 2 items with binding law in 1 jurisdiction. Engineering guidance, not legal advice.

Standard / soft law

Human oversight should allow AI decisions to be overturned

UNESCO Recommendation (2021) para. 36 · official text · Ethics framework (not binding law)

UNESCO's Recommendation calls for retained human oversight so AI decisions and actions can be overturned by humans, with responsibility attributable to a person. Detect consequential AI decision/action paths with no human override/overturn affordance. Broadest-adoption ethics instrument.

Who it applies to

Duty falls on: deployer, operator
Any AI actor deploying consequential AI. Adopted by 193 UNESCO member states; advisory.

The guard to add

Give a human a working way to review and overturn each consequential AI decision: a pending-review step before it takes effect and an override that restores the prior state.

Two pieces on the path where model output becomes an effect (status change, record update, letter, tool execution). Before the effect, consequential decisions wait in a pending_review state or an agent interrupt (LangGraph interrupt_before or interrupt(), Claude Agent SDK can_use_tool) where an assigned overseer sees the output in context and can accept, change, or disregard it. After the effect, an override route (for example POST /decisions/{id}/override or reverse_decision) lets an authorized person reverse the outcome, restores the prior state, and records who overturned it and why, so responsibility is attributable to a person.

Where it goes: 15 agent action surface, 1 application source code, 2 data models.

Example (LangGraph), before:

app = builder.compile()
app.invoke({'application': application})

After:

app = builder.compile(checkpointer=MemorySaver(), interrupt_before=['apply_decision'])
config = {'configurable': {'thread_id': application.id}}
app.invoke({'application': application}, config)   # pauses before apply_decision
# overseer UI shows the state; the reviewer accepts, edits, or discards the AI output
app.update_state(config, {'decision': reviewer_decision, 'reviewed_by': reviewer.id})
app.invoke(None, config)

Control: AI decisions cannot be overturned by humans. The same guard addresses 2 items with binding law in 1 jurisdiction. Engineering guidance, not legal advice.
