Article 4a inserted, Article 10(5) deleted

Since 27 July 2026 the legal basis for bias detection using special categories of personal data sits as Article 4a in Chapter I and no longer as Article 10(5) in Chapter III. The circle has widened from providers of high-risk systems alone to providers and deployers of other AI systems and models and deployers of high-risk systems, on the same conditions.

- Condition | allParagraph 1 is open only to the provider of a high-risk AI system, and only to the extent that the processing is strictly necessary to detect and correct bias in accordance with Article 10(2), points (f) and (g). The deployer cannot rely on this paragraph, not even for a high-risk system; for the deployer the route runs through paragraph 2.
- Condition | allParagraph 2 is open to providers and deployers of other AI systems and models and to deployers of high-risk AI systems, but carries its own substantive threshold: the processing must be strictly necessary in view of possible biases that are likely to affect the health and safety of persons, have a negative impact on fundamental rights or lead to discrimination prohibited under Union law, especially where data outputs influence inputs for future operations. Bias without one of those consequences falls outside it.
- Condition | allThe six conditions in paragraph 1 are cumulative and, through paragraph 2, point (b), apply to the wider circle as well: (a) other data, including synthetic or anonymised data, demonstrably do not suffice; (b) technical limitations on re-use apply plus state of the art security and privacy preserving measures, including pseudonymisation; (c) there is strict access control with documentation and confidentiality; (d) the data are not transmitted, transferred or otherwise accessed by other parties; (e) they are deleted once the bias has been corrected or the retention period ends, whichever comes first; (f) the record of processing activities states why the processing was strictly necessary and why the objective could not be achieved with other data.
- ExceptionParagraph 2 closes by providing that it creates no obligation to carry out bias detection and correction. Article 4a is therefore a basis and not an instruction: without carrying out such processing there is nothing to comply with under this article, there is no date by which anything must be done, and outside the purpose of bias detection and correction it grants no room at all.
As long as this exception is not ruled out, the outcome stays conditional and you have to establish it yourself.

What this object states

Official fact

Attributable to a named primary source, with a locator. Where they differ, the official source prevails.

Regulation (EU) 2026/1744 inserted Article 4a and deleted Article 10(5) with effect from 27 July 2026. Anyone justifying a processing operation by reference to Article 10(5) has since been referring to a deleted provision.
