Binding law — in force AI-adjacent law

Solely automated decisions with legal or similar significant effects need human intervention, the person's view and a way to contest (Nigeria NDPA s. 37)

Official Gazette No. 119, Vol. 110, Lagos, 1st July, 2023 (masthead) · official text · In force: applies since 12 Jun 2023 · NG

Nigeria's Data Protection Act, 2023 gives a data subject the right not to be subject to a decision based solely on automated processing of personal data, including profiling, that produces legal or similar significant effects concerning them (s. 37(1)), except where the decision is necessary for a contract between the data subject and the controller, authorised by a written law with suitable safeguards, or authorised by the data subject's consent (s. 37(2)). The data controller must implement suitable measures to safeguard the data subject's rights, including the rights to obtain human intervention, to express their point of view and to contest the decision (s. 37(3)). Before collecting personal data, the controller must tell the data subject of the existence of automated decision-making, including profiling, its significance and envisaged consequences, and the right to object to and challenge it (s. 27(1)(g)). Detect a model output that becomes a decision about a person with no human-intervention and contest route, and no human decision.

Detectors

1 detector (data flow), experimental: written from the rule's text and not yet measured for precision on real code, so treat a hit as a lead to verify.

Known limits:

  • The s. 27(1)(g) notice at collection is not detected
  • Whether a contract, written law or consent exception applies (s. 37(2)) is not detected
  • Decisions without legal or similar significant effect are outside s. 37; the contest form may live in a separate service.

Who it applies to

  • Duty falls on: controller
  • Systems covered: automated decision, consequential decision
  • Data controllers domiciled in, resident in or operating in Nigeria, processing personal data in Nigeria, or processing personal data of a data subject in Nigeria from outside it (s. 2(2)), that take decisions based solely on automated processing, including profiling, with legal or similar significant effects. In force since commencement on 2023-06-12. Whether the s. 37(3) measures apply to every such decision or only to those taken under a s. 37(2) exception, and whether a s. 3(2) purpose reaches s. 37, are counsel questions.
  • Not covered:
    • Processing by one or more persons solely for personal or household purposes, unless it violates a data subject's fundamental right to privacy (s. 3(1))
  • Whether it applies depends on facts outside the code; a person has to decide.

The guard to add

Route significant automated decisions through meaningful human review, or wire in an automated-decision notice, reasons, human intervention, a way to give a view, and contest.

At the point where model output becomes a significant decision about a person (approve, deny, underwrite, set_status), either queue the case for a reviewer who weighs the evidence and can change the outcome before it takes effect (review_queue.enqueue, requires_human_review), or, where the decision stays solely automated, record the permitted basis for that decision type and wire the safeguards in. Those safeguards are a notice in the decision message that it was made by automated processing, reasons the person can read, and request_human_review or contest routes where the person can give their view and have a human reconsider. A reviewer who approves every case without examining it does not make the decision non-automated, so the review records reviewer identity, the evidence viewed, and the outcome.

Where it goes: 1 application source code, 9 AI output handling, 15 agent action surface, 14 user-facing text.

What this provision adds:

  • Before collecting personal data, tell the person that automated decision-making, including profiling, is used, its significance and envisaged consequences, and their right to object to and challenge it (s. 27(1)(g)).
  • Let the person obtain human intervention on the controller's part, express their point of view and contest the decision (s. 37(3)).

Example (Python + OpenAI SDK), before:

verdict = client.chat.completions.create(model=MODEL, messages=msgs).choices[0].message.content
if verdict.strip() == 'deny':
    deny(applicant)
    send_decision_email(applicant, 'Your application was not approved.')

After:

out = client.chat.completions.create(model=MODEL, messages=msgs,
                                     response_format={'type': 'json_object'})
result = json.loads(out.choices[0].message.content)
if result['decision'] == 'deny':
    if requires_human_review('credit'):                 # a person decides
        review_queue.enqueue(applicant.id, proposal=result)
    else:                                               # solely automated, recorded basis
        deny(applicant, basis=DECISION_BASIS['credit'], reasons=result['reasons'])
        send_decision_email(applicant, render('adm_denial.txt', notice=ADM_NOTICE,
            reasons=result['reasons'], contest_url=f'{BASE}/decisions/{applicant.id}/contest'))
