Legal File 4.09: Making Human Validation Genuinely Mandatory
Validation is not a formality: the responsible person must understand, control, challenge and remain accountable.
A human in the loop is not enough
Measure 4.09 requires human intervention for any adverse decision. Human presence is meaningless if the person lacks time, information, competence or power to disagree with the system. The law must therefore define effective human oversight.
The reviewer’s powers
Verify
Access the case file and underlying sources.
Reject
Disregard the output without automatic penalty.
Suspend
Stop the tool when risk or incident appears.
Explain
Give independent reasons for the final decision.
Remain accountable
Be identifiable and legally responsible.
Adverse decisions
| Example | Why validation is required |
|---|---|
| Rejection or inadmissibility | The person may lose access to a claim. |
| Penalty or aggravation | The legal position is worsened. |
| Refusal of a right | A negative legal effect follows. |
| More burdensome procedure | The output increases delay or constraint. |
| Risk flag | A score may trigger enhanced scrutiny. |
No sham validation
Rubber-stamping is prohibited. Batch signatures, preselected approval buttons or a process in which disagreement requires special permission do not amount to effective oversight.
European-law link
The EU AI Act requires human oversight for high-risk systems, proportionate to risk and context. Oversight personnel must have competence, training and authority. The proposed French clauses apply those principles to judicial use.
