May an AI selection tool distinguish between candidates on the basis of sex, origin or other characteristics?

No. The General Equal Treatment Act prohibits direct and indirect distinction when offering and filling a vacancy, when entering into and terminating an employment relationship and in promotion. An apparently neutral criterion that particularly affects people with a protected characteristic is also prohibited, unless it is objectively justified. For age and for disability or chronic illness, separate acts with a comparable prohibition apply to recruitment and selection.

What is prohibited

Distinction is prohibited when offering a position and in the treatment when filling it, and when entering into and terminating an employment relationship [1], and also in promotion [2]. Distinction also includes indirect distinction: an apparently neutral provision, criterion or practice that particularly affects persons of a certain religion, belief, political opinion, race, sex, nationality, heterosexual or homosexual orientation or marital status [3].

Age, disability and chronic illness

Age is not in the General Equal Treatment Act, but in the Act on equal treatment on the ground of age in employment [8]. That act prohibits distinction when offering and filling a position and when entering into and terminating an employment relationship [9]. For disability or chronic illness the same applies under the Act on equal treatment on the ground of disability or chronic illness [10] [11]. Both acts have their own exceptions. An AI tool that, for example, scores candidates with a lot of work experience or with gaps in their career lower can therefore also fall under these acts.

When indirect distinction is allowed

Indirect distinction is allowed if it is objectively justified by a legitimate aim and the means are appropriate and necessary [4]. A selection criterion of an AI tool, such as a postcode, an educational institution or a gap in the CV, can be such a criterion. Have it tested whether the outcomes particularly affect groups with a protected characteristic, and record why each criterion is necessary.

What the AI Act adds

Since the amendment by Regulation (EU) 2026/1744, a deployer may exceptionally process special categories of personal data where strictly necessary to detect and correct bias that may lead to prohibited discrimination, under strict conditions; that is not a duty [5]. From 2 December 2027, for a high-risk system you must also ensure that the input data you control is relevant and sufficiently representative [6] [7].
